2. How to prepare for FAANGM jobs interviews
You must be able to write code. It is as simple as that. Prepare for the interview by practicing coding exercises in different categories. You’ll solve one or more coding problems focused on CS fundamentals like algorithms, data structures, recursions, and binary trees.
Coding Interview Tips These tips from FAANGM engineers can help you do your best.
Make sure you understand the question. Read it back to your interviewer. Be sure to ask any clarifying questions.
An interview is a two-way conversation; feel free to be the one to ask questions, too.
Don’t rush. Take some time to consider your approach. For example, on a tree question, you’ll need to choose between an iterative or a recursive approach. It’s OK to first use a working, unoptimized solution that you can iterate on later.
Talk through your thinking and processes out loud. This can feel unnatural; be sure to practice it before the interview.
Test your code by running through your problem with a few test and edge cases. Again, talk through your logic out loud when you walk through your test cases.
Think of how your solution could be better, and try to improve it. When you’ve finished, your interviewer will ask you to analyze the complexity of the code in Big O notation.
Walk through your code line by line and assign a complexity to each line.
Remember how to analyze how “good” your solution is: how long does it take for your solution to complete? Watch this video to get familiar with Big O Notation.
How to Approach Problems During Your Interview
Before you code
• Ask clarifying questions. Talk through the problem and ask follow-up questions to make sure you understand the exact problem you’re trying to solve before you jump into building the solution. • Let us know if you’ve seen the problem previously. That will help us understand your context. • Present multiple potential solutions, if possible. Talk through which solution you’re choosing and why.
While you code
• Don’t forget to talk! While your tech screen will focus heavily on coding, the engineer you’re interviewing with will also be evaluating your thought process. Explaining your decisions and actions as you go will help the interviewer understand your choices. • Be flexible. Some problems have elegant solutions, and some must be brute forced. If you get stuck, just describe your best approach and ask the interviewer if you should go that route. It’s much better to have non-optimal but working code than just an idea with nothing written down. • Iterate rather than immediately trying to jump to the clever solution. If you can’t explain your concept clearly in five minutes, it’s probably too complex. • Consider (and be prepared to talk about): • Different algorithms and algorithmic techniques, such as sorting, divide-and-conquer, recursion, etc. • Data structures, particularly those used most often (array, stack/queue, hashset/hashmap/hashtable/dictionary, tree/binary tree, heap, graph, etc.) • O memory constraints on the complexity of the algorithm you’re writing and its running time as expressed by big-O notation. • Generally, avoid solutions with lots of edge cases or huge if/else if/else blocks, in most cases. Deciding between iteration and recursion can be an important step
After you code
• Expect questions. The interviewer may tweak the problem a bit to test your knowledge and see if you can come up with another answer and/or further optimize your solution. • Take the interviewer’s hints to improve your code. If the interviewer makes a suggestion or asks a question, listen fully so you can incorporate any hints they may provide. • Ask yourself if you would approve your solution as part of your codebase. Explain your answer to your interviewer. Make sure your solution is correct and efficient, that you’ve taken into account edge cases, and that it clearly reflects the ideas you’re trying to express in your code.
Reverse to Make Equal: Given two arrays A and B of length N, determine if there is a way to make A equal to B by reversing any subarrays from array B any number of times. Solution here
Contiguous Subarrays: You are given an array arr of N integers. For each index i, you are required to determine the number of contiguous subarrays that fulfills the following conditions:
The value at index i must be the maximum element in the contiguous subarrays, and These contiguous subarrays must either start from or end on index i. Solution here
Add 2 long integer (Example: “1001202033933333093737373737” + “934019393939122727099000000”) Solution here
# Python3 program to find sum of
# two large numbers.
# Function for finding sum of
# larger numbers
def findSum(str1, str2):
# Before proceeding further,
# make sure length of str2 is larger.
if (len(str1) > len(str2)):
t = str1;
str1 = str2;
str2 = t;
# Take an empty string for
# storing result
str = "";
# Calculate length of both string
n1 = len(str1);
n2 = len(str2);
# Reverse both of strings
str1 = str1[::-1];
str2 = str2[::-1];
carry = 0;
for i in range(n1):
# Do school mathematics, compute
# sum of current digits and carry
sum = ((ord(str1[i]) - 48) +
((ord(str2[i]) - 48) + carry));
str += chr(sum % 10 + 48);
# Calculate carry for next step
carry = int(sum / 10);
# Add remaining digits of larger number
for i in range(n1, n2):
sum = ((ord(str2[i]) - 48) + carry);
str += chr(sum % 10 + 48);
carry = (int)(sum / 10);
Rotational Cipher: One simple way to encrypt a string is to “rotate” every alphanumeric character by a certain amount. Rotating a character means replacing it with another character that is a certain number of steps away in normal alphabetic or numerical order.For example, if the string “Zebra-493?” is rotated 3 places, the resulting string is “Cheud-726?”. Every alphabetic character is replaced with the character 3 letters higher (wrapping around from Z to A), and every numeric character replaced with the character 3 digits higher (wrapping around from 9 to 0). Note that the non-alphanumeric characters remain unchanged.Given a string and a rotation factor, return an encrypted string. Solution here
Matching Pairs: Given two strings s and t of length N, find the maximum number of possible matching pairs in strings s and t after swapping exactly two characters within s.A swap is switching s[i] and s[j], where s[i] and s[j] denotes the character that is present at the ith and jth index of s, respectively. The matching pairs of the two strings are defined as the number of indices for which s[i] and t[i] are equal. Note: This means you must swap two characters at different indices. Solution here
Minimum Length Substrings: You are given two strings s and t. You can select any substring of string s and rearrange the characters of the selected substring. Determine the minimum length of the substring of s such that string t is a substring of the selected substring. Solution here
Recursion
Encrypted Words: You’ve devised a simple encryption method for alphabetic strings that shuffles the characters in such a way that the resulting string is hard to quickly read, but is easy to convert back into the original string. When you encrypt a string S, you start with an initially-empty resulting string R and append characters to it as follows: Append the middle character of S (if S has even length, then we define the middle character as the left-most of the two central characters) Append the encrypted version of the substring of S that’s to the left of the middle character (if non-empty) Append the encrypted version of the substring of S that’s to the right of the middle character (if non-empty) For example, to encrypt the string “abc”, we first take “b”, and then append the encrypted version of “a” (which is just “a”) and the encrypted version of “c” (which is just “c”) to get “bac”. If we encrypt “abcxcba” we’ll get “xbacbca”. That is, we take “x” and then append the encrypted version “abc” and then append the encrypted version of “cba”.
Slow Sums: Suppose we have a list of N numbers, and repeat the following operation until we’re left with only a single number: Choose any two numbers and replace them with their sum. Moreover, we associate a penalty with each operation equal to the value of the new number, and call the penalty for the entire list as the sum of the penalties of each operation.For example, given the list [1, 2, 3, 4, 5], we could choose 2 and 3 for the first operation, which would transform the list into [1, 5, 4, 5] and incur a penalty of 5. The goal in this problem is to find the worst possible penalty for a given input.
Reverse Operations: You are given a singly-linked list that contains N integers. A subpart of the list is a contiguous set of even elements, bordered either by either end of the list or an odd element. For example, if the list is [1, 2, 8, 9, 12, 16], the subparts of the list are [2, 8] and [12, 16].Then, for each subpart, the order of the elements is reversed. In the example, this would result in the new list, [1, 8, 2, 9, 16, 12].The goal of this question is: given a resulting list, determine the original order of the elements. Solution Here.
Hash Tables
Pair Sums: Given a list of n integers arr[0..(n-1)], determine the number of different pairs of elements within it which sum to k. If an integer appears in the list multiple times, each copy is considered to be different; that is, two pairs are considered different if one pair includes at least one array index which the other doesn’t, even if they include the same values. Solution here.

The interviewer will be thinking about how your skills and experience might help their teams.
Help them understand the value you could bring by focusing on these traits and abilities. • Communication: Are you asking for requirements and clarity when necessary, or are you just diving into the code? Your initial tech screen should be a conversation, so don’t forget to ask questions. • Problem solving: They are evaluating how you comprehend and explain complex ideas. Are you providing the reasoning behind a particular solution? Developing and comparing multiple solutions? Using appropriate data structures? Speaking about space and time complexity?Optimizing your solution? • Coding. Can you convert solutions to executable code? Is the code organized and does it capture the right logical structure? • Verification. Are you considering a reasonable number of test cases or coming up with a good argument for why your code is correct? If your solution has bugs, are you able to walk through your own logic to find them and explain what the code is doing?

I am not a lawyer, but I believe there is some sort of legal restrictions on what an internship can be (in California, at least). In my previous company, we had discussed cases on whether or not someone who was out of school can be an intern, and we got an unequivocal verdict that you have to be in school, or about to start school (usually college or graduate school, but high school can work too), in order to be considered for an internship.
I suspect the reason for this is to protect a potential intern from exploitation by companies who would offer temporary jobs to people while labeling them as learning opportunities in order to pay less.
Personally, I feel for people like you, in an ideal world you should be allowed to have the same opportunities as the formally schooled people, and occasionally there are. For example, some companies offer residency programs which are a bit similar to internships. In many cases, though, these are designed to help underrepresented groups. Some examples include:
This is a common bug in the thinking of people, doing the wrong thing harder in the hope that it works this time. Asking tough questions is like hitting a key harder when the broken search function in LinkedIn fails. No matter how hard you hit the key, it won’t work.
Given the low quality of the LinkedIn platform from a technical perspective it seems hard to imagine that they hire the best or even the mediocre. But it may be that because their interviews are too tough to hire good programmers.
Just because so few people can get a question right, does not mean it is a good question, merely that it is tough. I am also a professional software developer and know a bunch of algorithms, but also am wholly ignorant of many others. Thus it is easy to ask me (or anyone else) questions they can’t answer. I am (for instance) an expert on sort/merging, and partial text matching, really useful for big data, wholly useless for UX.
So if you ask about an obscure algorithm or brain teaser that is too hard you don’t measure their ability, but their luck in happening to know that algo or having seen the answer to a puzzle. More importantly how likely are they to need it ?
This is a tricky problem for interviewers, if you know that a certain class of algorithms are necessary for a job, then if you’re a competent s/w dev manager then odds are that you’ve already put them in and they just have to integrate or debug them. Ah, so I’ve now given away one of my interview techniques. We both know that debugging is more of our development effort than writing code. Quicksort (for instance) is conceptually quite easy being taught to 16 year old Brits or undergraduate Americans, but it turns out that some implementations can go quadratic in space and/or time complexity and that comparison of floating point numbers is a sometimes thing and of course some idiot may have put = where he should have put == or >= when > is appropriate.
Resolving that is a better test, not complete of course, but better.
For instance I know more about integrating C++ with Excel than 99.9% of programmers. I can ask you why there are a whole bunch of INT 3’s laying around a disassembly of Excel, yes I have disassembled Excel, and yes my team was at one point asked to debug the damned thing for Microsoft. I can ask about LSTRs, and why SafeArrays are in fact really dangerous. I can even ask you how to template them. That’s not easy, trust me on this.
Are you impressed by my knowledge of this ?
I sincerely hope not.
Do you think it would help me build a competent search engine, something that the coders at LinkedIn are simply unable to do ?
No.
I also know a whole bunch of numerical methods for solving PDEs. Do you know what a PDE even is ? This can be really hard as well. Do you care if you can’t do this ? Again not relevant to fixing the formless hell of LI code. fire up the developer mode of your browser and see what it thinks of Linkedin’s HTML, I’ve never seen a debugger actually vomit in my face before.
A good interview is a measure not just of ability but of the precise set of skills you bring to the team. A good interviewer is not looking for the best, but the best fit.
Sadly some interviewers see it as an ego thing that they can ask hard questions. So can I, but it’s not my job. My job is identfying those that can deliver most, hard questions that you can’t answer are far less illuminating that questions you struggle with because I get to see the quality of your thinking in terms of complexity, insight, working with incomplete and misleading information and determination not to give up because it is going badly.
Do you as a candidate ask questions well ? If I say something wrong, do you a) notice, b) have the soft skills to put it to me politely, c) have the courage to do so ?
Courage is an under-rated attribute that superior programmers have and failed projects have too little of.
Yes, some people have too much courage, which is a deeper point, where for many things there is an optimum amount and the right mix for your team at this time. I once had to make real time un-reversible changes to a really important database whilst something very very bad happened on TV news screens above my head. Too much or too little bravery would have had consequences. Most coding ain’t that dramatic, but the superior programmer has judgement, when to try the cool new language/framework feature in production code, when to optimise for speed, or for space and when for never ever crashes even when memory is corrupted by external effects. When does portability matter or not ? Some code will only be used once and we both know some of it will literally never be executed in live, do we obsess about it’s quality in terms of performance and maintainability .
The right answer is it depends, and that is a lot more important to hiring the best than curious problems in number theory or O(N Log(N)) for very specific code paths that rarely execute.
Also programming is a marathon, not a sprint, or perhaps more like a long distance obstacle course, stretches of plodding along with occasional walls. Writing a better search engine than LinkedIn “programmers” manage is a wall, I know this because my (then) 15 year old son took several weeks, at 15, he was only 2 or 3 times better than the best at LinkedIn, but he’s 18 now and as a professional grade programmer, him working for LinkedIn would be like putting the head of the Vulcan Science Academy in among a room of Gwyneth Paltrow clones.
And that ultimately may be the problem.
Good people have more options and if you have a bad recruitment process then they often will reject your offer. We spend more of our lives with the people we work with than sleep with and if at interview management is seen as pompous or arrogant then they won’t get the best people.

ASTON MARTIN RAPIDE E
Secret agent James Bond’s favorite British automaker will take the wraps off it’s its first battery-powered ride by year’s end, and it’s a true exotic sports car. Based on the low-slung Rapide coupe, production will be limited to 155 units worldwide, with a sky-high sticker price. It’s expected to run for around 200 miles on a charge and register a 0-60 mph time of less than four seconds.
BOLLINGER B1
Fledgling EV maker Bollinger Motors is ramping up to launch its first model, the B1 for 2020. It’s a decidedly boxy SUV and it looks a lot like a classic Land Rover. It’s built on an aluminum frame and comes with a dual-motor electric all-wheel-drive system. The B1 promises a 200-mile range with 613 horsepower and a strong 668 pound-feet of torque, and is said to tow as much as 7,500 pounds.
Now entering a new class of strength, speed and versatility—only possible with an all-electric design. The powerful drivetrain and low center of gravity provides extraordinary traction control and torque—enabling acceleration from 0-60 mph in as little as 2.9 seconds and up to 500 miles of range.
Cybertruck is a vehicle that has better utility than an F-150, while beating out a Porsche 911 in performance.
Cybertruck is designed with 30X Stainless Steel, which is also used on Starship. Cybertruck uses this material for maximum durability, function, and design.
Cybertruck is a beautiful platform for a wildly futuristic design, which contains insane performance, on-road or off-road, regardless.
Cybertruck contains a beautiful full-width unibrow LED bar for a headlight, evident of form, and function packed into one package. With this headlight, maximum visibility is always present, whether at night, or at day with it’s beautiful Always-On LEDs.
With it’s ability to sprint from 0-60 in under 2.9s and be virtually bulletproof, Cybertruck is the best platform for an advanced, beautiful, technological reliant future.
Absolutely! But I’m looking forward to an even better one — Cybertruck. I fell in love with that beast the moment I saw it, and put down a reservation as quickly as possible. I find myself near the head of a long, long waiting list for this revolutionary vehicle. I hope to take delivery of a tri-motor within the first 5000 off the assembly line.
Even before seeing it up close and in person, I know it will be the best vehicle I’ll ever purchase. It goes beyond what I love about my Model 3 AWD. I don’t think of it as a pickup truck. I would never buy a traditional pickup for as little as I would use it as such. Cybertruck is an all-in-one vehicle. It’s a pickup truck, sure, but it’s also an SUV that seats six and has 100 cu ft of secure, weather protected storage. I plan to use it for wilderness camping in hard to get to places by virtue of its exemplary off-roading capabilities.
I will happily take my Cybertruck on cross country road trips. The self-driving capabilities of Tesla vehicles make long distance cruising an enjoyable experience, devoid of the typical driving fatigue that I’ve always endured traveling in other cars I’ve owned, even my Class B motor-home, which I recently sold. I’m looking forward to spending time in the back country of Alaska with the grizzlies and the moose (safely tucked inside CT, of course).
Cybertruck will be the most durable vehicle I’ve ever owned, as well. That 3mm cold rolled stainless steel exoskeleton is dent proof, bullet proof, and rust proof. The windows are almost impossible to break, and the rolling tonneau cover is strong enough to support the weight of a 200+ lb man.
Cybertruck comes without paint of any kind which is great for squeezing through brush on abandoned logging roads. No need to hold back to avoid scratching the finish. I may have the truck painted, though, just to give it a personalized touch.
My Cybertruck won’t be left unused. It will be my daily driver. Sure, it’s large, but it won’t be like driving one of those behemoths from Detroit. It’s fast and responsive. The air suspension can be lowered to make it easier to get in and out of, improve handling, and reduce aerodynamic drag.
Add to that its 3500 lbs load capacity, its 14,000 lb towing capacity, 500+ mile range, and fast charging at the ever-expanding Tesla Supercharger network, and it’s easy to understand how this vehicle will be the best, and probably the last, vehicle I’ll ever own. Unless I deploy it to the Tesla Network as a robotaxi in a couple of years. Now there’s a money making idea!
KIA SOUL EV
Kia is redesigning its funky/boxy compact full-electric hatchback for 2020 with fresh styling and myriad improvements. A new 64 kWh liquid-cooled lithium ion polymer battery pack should deliver well in excess of 200 miles on a charge. Power will be bumped up to 200 horsepower with 291 pound-feet of torque. It will come with four drive modes and four levels of regenerative braking, including a setting for one-pedal driving.
MERCEDES-BENZ EQC
The EQC is the first in what will be a series of luxury EVs coming from Mercedes-Benz. It’s a boldly styled SUV with two electric motors that combine for an output of 402 horsepower with 564 pound-feet of torque. All-wheel-drive will be standard, along with a long list of convenience, connectivity, and safety features. In Europe it’s rated to run for 279 miles on a full charge, though that number may be somewhat lower when evaluated by U.S. standards.
MINI ELECTRIC
BMW’s Mini brand is developing a new full-electric version of the comely Cooper coupe, likely for later in 2020. Details, however, remain sketchy. Only scant visual tidbits like this one remain available. Reports say it will share technology with the BMW i3, and could run for as many as 200 miles on a full charge. Expect it to deliver Mini’s famed go-kart-like handling.
POLESTAR 2
Volvo is launching a new high-tech sub-brand this year called Polestar. While its first model, the Polestar 1, will be a plug-in hybrid, the Polestar 2 is a sleekly cast full-electric luxury four-door hatchback. Intended to compete with the Tesla Model 3, the automaker is targeting a range of 275 miles on a charge, with its two electric motors expected to put around a combined 485 pound-feet of torque to the pavement. All-wheel drive will come standard.
PORSCHE TAYCAN
Porsche’s first full-electric model will be an ultra-exotic battery-powered four-door sports car. It’s said to leap off the line and reach 62 mph (100 km/h) in a sudden 3.5 seconds. The automaker claims around 300 miles of range with a full battery, with the ability to recharge about 60 miles worth of energy in just four minutes.
RIVIAN R1T
Yet another startup EV builder, Rivian plans to introduce a futuristic-looking pickup truck for 2020 to be built in the former Mitsubishi factory in Normal, IL. No mere poseur, the R1T is said to deliver a 400-mile range, with its quad-motor system enabling off-road adventures and a 0-60 mph time of just three seconds on paved roads.
TESLA MODEL Y
Expected sometime during 2020, assuming the automaker incurs no production delays or other corporate calamities, the Tesla Model Y will essentially be a crossover SUV version of the Model 3 sedan. Smaller and less expensive than the Model X, it’s sure to become the company’s best selling model. It will initially come in performance, long-range, and dual motor all-wheel drive variants with specs similar to the Model 3.
TESLA ROADSTER
Tesla’s original Roadster was its first model and it broke new ground in terms of performance and operating range. It’s coming back for 2020 with a freshly curvy profile and uncanny performance. Tesla claims it will fly to 60 mph in a rocket-like 1.9 seconds, reach a felonious top speed of 250 mph, and run for a seemingly impossible 620 miles with a full charge.
When going at a constant speed downhill – the car uses regenerative braking to maintain that speed without going faster and faster.
In effect, the electric motor(s) in the car are turned in to generators – and charge up the battery as they go.
Here is an actual screen shot from my Tesla Model 3 – taken shortly after driving over the Franklin Mountains in El Paso…it’s a graph of the energy consumed per mile driven over the last 30 minutes (kinda like the “mpg” number for a gasoline car):
I bought a Model 3 Standard Range Plus with Full-Self-Driving – a little over a year ago.
I went online – did all of the options selection, all of the financing, taxing and insuring in about 40 minutes – and without ever speaking to an actual human. The deposit money was taken from my credit card.
The car was on a 14day delivery back then – but it took a little longer – more like three3 weeks.
During which time, I had to put up with just a model-Model-3:
The full-sized model 3 was delivered on a large covered car transporter – theoretically to my front door – but in fact the driver phoned me to say he couldn’t get through the twisty streets in my neighborhood in his gigantic truck – so we met him in a nearby street. He offloaded the car – gave me time to inspect it – handed me the “credit card” car keys – and that was that. So I drove it the last 100 yards home.
This is by FAR the most pleasant way to buy a car.
SNAFU’S AND MINOR GLITCHES:
There were some SNAFU’s and complications…mostly because I live in Texas where it’s illegal for a car company to sell direct to a customer…this is true in about 50% of US states.
So what happened was that the car was sold to me in Arizona – where it’s legal. The car was delivered by Tesla to their distribution center in Phoenix Arizona – where I actually purchased it. Then Tesla did the work to re-title the car in Texas at their expense.
The car was not shipped in a Tesla transporter but by some 3rd party (whom Tesla also paid).
This complicated little legal dance would not have been noticeable to me EXCEPT that there was some confusion about my insurance. They couldn’t re-title the car to me without it being insured – and I couldn’t insure it without a VIN – and somewhere along the line someone dropped the ball.
So the car arrived with no temporary licence plates and I had to go back to Tesla and have them do that after the insurance SNAFU got ironed out. I’m still not sure whether it was their fault, my fault, my insurance company’s fault – or the DMV here in El Paso’s fault…I’m betting the latter because we’re pretty sure ours was the first Tesla ever sold here.
Although companies like Uber and Tesla are not very successful in that aspect, fully self driving cars will have to be able to avoid collisons by all means. They simply will have to be designed in a way that they do not crash against something.
Okay, so what will a self driving car do, when another driver deliberately cuts its lane? What, if some guys make a fun out of throwing garbage cans at self driving cars? What, if some unemployed taxicab drivers try to make a ride in a self-driving taxicab as unpleasant as possible?
This is unlikely? Tell me why people spend extra money in order to make their trucks pollute the air as much as possible:
CyberTruck will cost half the competition, and here’s why the math says it works
You are given an array arr of N integers. For each index i, you are required to determine the number of contiguous subarrays that fulfills the following conditions:
The value at index i must be the maximum element in the contiguous subarrays, and
These contiguous subarrays must either start from or end on index i.
Signature int[] countSubarrays(int[] arr)Input
Array arr is a non-empty list of unique integers that range between 1 to 1,000,000,000
Size N is between 1 and 1,000,000
Output An array where each index i contains an integer denoting the maximum number of contiguous subarrays of arr[i]Example: arr = [3, 4, 1, 6, 2] output = [1, 3, 1, 5, 1]Explanation:
For index 0 – [3] is the only contiguous subarray that starts (or ends) with 3, and the maximum value in this subarray is 3.
For index 1 – [4], [3, 4], [4, 1]
For index 2 – [1]
For index 3 – [6], [6, 2], [1, 6], [4, 1, 6], [3, 4, 1, 6]
For index 4 – [2]
So, the answer for the above input is [1, 3, 1, 5, 1]
Rotational Cipher: One simple way to encrypt a string is to “rotate” every alphanumeric character by a certain amount. Rotating a character means replacing it with another character that is a certain number of steps away in normal alphabetic or numerical order. For example, if the string “Zebra-493?” is rotated 3 places, the resulting string is “Cheud-726?”. Every alphabetic character is replaced with the character 3 letters higher (wrapping around from Z to A), and every numeric character replaced with the character 3 digits higher (wrapping around from 9 to 0). Note that the non-alphanumeric characters remain unchanged. Given a string and a rotation factor, return an encrypted string.
Signature
string rotationalCipher(string input, int rotationFactor)
Given a list of n integers arr[0..(n-1)], determine the number of different pairs of elements within it which sum to k. If an integer appears in the list multiple times, each copy is considered to be different; that is, two pairs are considered different if one pair includes at least one array index which the other doesn’t, even if they include the same values.
Signature
int numberOfWays(int[] arr, int k)
Input
n is in the range [1, 100,000]. Each value arr[i] is in the range [1, 1,000,000,000]. k is in the range [1, 1,000,000,000].
Output
Return the number of different pairs of elements which sum to k.
Example 1
n = 5 k = 6 arr = [1, 2, 3, 4, 3] output = 2The valid pairs are 2+4 and 3+3.
Example 2
n = 5 k = 6 arr = [1, 5, 3, 3, 3] output = 4There’s one valid pair 1+5, and three different valid pairs 3+3 (the 3rd and 4th elements, 3rd and 5th elements, and 4th and 5th elements).
Solution using Python:
Complexity:
Time: O(n)
Space: Array of n and Hash of n (Who cares about space?? really ??)
Execution:
Case 1:
[1, 2, 3, 4, 3] {1: 1, 2: 1, 3: 2, 4: 1} Total Pairs is: 2.0
Case 2:
[1, 5, 3, 3, 3] {1: 1, 5: 1, 3: 3} Total Pairs is: 4.0

Question 1:In our subscription, we have four different resource groups. They are RG1, RG2, RG3, RG4. RG2 has a Read-only lock at the resource group scope. RG3 has a Delete lock at the resource group scope. RG1 and RG4 do not have locks. We need to determine how we could move resources between resource groups during the lifecycle of these resources. Assuming all resources provisioned support moving between resource groups regardless of region. Which of the following statements are plausible?
A. We can move resources from RG1 to RG4.
B. We can move resources between any of these resource groups.
C. We can move resources from RG2 to RG4.
D. We can move resources from RG4 to RG3.
E. We can move resources from RG2 to RG3.
ANSWER1:
A and D.
Notes: We can effectively move resources from RG1 and RG4 because RG1 does not have a lock. We can move resources from RG4 and RG3 because RG4 does not have a lock. Also, while RG3 does have a Delete lock this does not stop resources from being moved into this resource group.
Question 2: Your company has recently added a few new users to your Azure Active Directory. You have already added them to an active directory group, and now you have asked them to add their devices to the domain. When they add their devices, you have to ensure they are prompted to use a mobile phone to verify their identity. How do you configure this?
A. Require multi-factor authentication to join devices
B. Configure a point-to-site VPN
C. Enable Conditional Access
D. You must sign up for Azure AD Premium
ANSWER2:
A
Notes: This setting in Azure Active directory will require multi-factor authentication for all devices under any conditions.
Question 3: Under your Azure Subscription, you are trying to identify VMs that are underutilized in order to shutdown all VMs with CPU utilization under 5%. Which blade should you use?
A. Customer Insights
B. Advisor recommendations
C. Monitor
D. Metrics
ANSWER3:
B
Notes: Advisor helps you follow best practices to optimize your Azure deployments. It analyzes your resource configuration and usage telemetry and then recommends solutions that can help you improve the cost-effectiveness, performance, high availability, and security of your Azure resources.
Question4: You have just purchased the domain name arseemagroup.com from a third party registrar. Using your Azure Active Directory domain, you’d like to create new users with the suffix @arseemagroup.com. Which three things must you do?
A. Access the custom domain names blade from Azure AD
B. Create a MX or TXT record from arseemagroup.com DNS
C. Verify that you own the domain name
D. Access the App registrations blade from Azure AD
ANSWER4:
A B and C
Notes: In order to add the domain “arseemagroup.com” to Azure AD, you must add the domain from the custom domain names blade.
When you add your custom domain to Azure AD, you must create an MX or TXT record with a destination address (provided) in order to verify that the domain does indeed belong to you.
When you add your custom domain to Azure AD, you must verify that this domain belongs to you by going through a verification process. Azure AD will provide the verification information.
Question 5: You have two subscriptions named Subscription1 and Subscription2. You are logged into Azure using Azure PowerShell from Computer1. How can you identify which subscription you are currently viewing and then switch from one subscription to the other for the current session at Computer1.
A. Set-AzContext -SubscriptionName
B. Get-AzContext
C. Select-AzContext
D. AzShow-Context
ANSWER5:
A and B
Notes: In Az PowerShell 3.7.0, Set-AzContext sets the tenant, subscription, and environment for cmdlets to use in the current session.
In Az PowerShell 3.7.0, 'Get-AzContext' gets the metadata used to authenticate Azure Resource Manager requests.
Question 6: You have two subscriptions named Subscription1 and Subscription2. You are currently managing resources in Subscription1 from Computer1 that has the Azure CLI installed. You need to switch to Subscription2. Which command should you run?
A. az set account –subscription “Subscription2”
B. az account set –subscription “Subscription2”
C. az subscription set “Subscription2”
D. Select-AzureSubscription -SubscriptionName “Subscription2”
ANSWER6:
B
Notes: You are accessing Azure from Computer1 with the Azure CLI installed; therefore, this command is the correct command.
Question 7: You work at the IT help desk for Consilium Corporation. You have been getting an influx of calls into the help desk about resetting users’ passwords. They keep reporting that they can’t seem to figure out how to reset their password in order to gain access to their Customer Relationship Management (CRM) software. What do you do?
A. Ensure that the users who are having problems are within the correct AD group
B. Make sure you have Azure Active Directory Free
C. Make sure they have their verification device (mobile app or access to email)
D. Verify that self-service password reset is enabled in Azure Active Directory
ANSWER7:
A C and D
Notes: Self-service password may not apply to those not in a specific Active Directory group. If the user is not in the group, they will not be able to reset their password.
In order to reset their password, the user will have to verify their identity using a mobile phone, mobile app, office phone or email.
Self-service password reset is an optional feature in Azure Active Directory, which may not apply to any and all users in the organization.
Question 8: In this scenario, we are working for Cloud Chase Support. We our the active administrator, and we have been tasked with determining how to ensure we do not incur costs in either our Prod-Subscription and our Dev-Subscription for virtual machine resources. We have a CloudChase management group where both subscription nested. We decide to use Azure Policy to enforce compliance on Virtual Machines. Our Policy definition states that virtual machines are not an allowed resource type at the scope of our CloudChase management group. There are some existing virtual machines in our Prod-Subscription at the time this policy is created. After the enforcement of our new policy which of the below statements is true?
A. We cannot create virtual machines in any subscription under the scope of our management group and our existing virtual machines will be deallocated.
B. Virtual machines can be created in our Prod-Subscription if they are compliant.
C. Virtual machines can be created in our Dev-Subscription.
D. We cannot create virtual machines in any subscription under the scope of our management group.
ANSWER8:
D
Notes: We created a policy that has a definition that defines that virtual machines are not a supported resource type at the scope of our management group. Any subscription under the scope of this management group will not support the provisioning of virtual machine resources.
Question 9: You recently signed up for Azure Active Directory Premium and need users to be able to reset their passwords if they are unable to login. What should you configure in Azure Active Directory?
A. Set “block sign-in” to off when creating the user
B. User password reset
C. User password change
D. Add user to sign-in group in Azure AD
ANSWER9:
B
Notes: With the password reset capability, the user will be able to click “forgot password” when trying to log in to the portal and reset their password on their own.
Question 10: You have an Azure Pay-as-you-go Subscription named Subscription1. You have some concerns about cost for Subscription1, and you would like to spend less than $100.00 US per month on all resources in this subscription. If you spend more than $90.00 US, you would like to get an alert in the form of a text message. What should you do?
A. Shutdown VMs when you are not using them
B. Create an alert in Azure Monitor
C. Create a budget alert condition tied to an action group
D. Create a budget in the subscriptions blade
ANSWER10:
C
Notes: Creating an alert condition is available when setting your budget, it is not required that you create an action group, however in this case where we want to be notified via SMS (text message), it is required that we tie an action group to our budget alert.
Question 11: We want to be provide an Azure AD B2B guest user the ability to manage all resources inside of our DevRG resource group. We want to give them these abilities over managing all resources inside of this resource group and nothing more. What role would we assign to the user to accomplish this goal? Assume we are assigning the role to the DevRG scope.
A. User Access Administrator
B. Owner
C. Contributor
D. Global Admin
ANSWER11:
C
Notes: This role will allow us to give this guest user the ability to manage all resources inside of the DevRG resource group, and nothing more like manage role assignments. This is exactly what we need for our scenario. When assigning permissions we need to think the principle of least privilege.
Question 12: You have just created a General-purpose V2 storage account in Azure. From a VM located in your on-prem environment, you’ve logged into your Azure subscription using the Connect-AzConnect command from the PowerShell command line. Next, you need to retrieve the key, in order to access your storage account. Which PowerShell cmdlet will you use to retrieve the access key?
A. Get-AzStorageAccount
B. Get-AzStorageContainerKey
C. Get-AzStorageContainerStoredAccessPolicy
D. Get-AzStorageAccountKey
ANSWER12:
D
Notes: The Get-AzStorageAccountKey cmdlet gets the access keys for an Azure Storage account.
Question 13: You have been directed to copy all data from one storage account to another using the AzCopy tool. You need to report which storage services you can copy. Which of those services would it be?

Question 14: You have a general purpose v1 storage account named consiliumstore that has a private container named container2. You need to allow read access to the data inside container2, but only within a 14 day window. How do you accomplish this using the Azure Portal?
A. Upgrade the storage account to general purpose v2
B. Create a shared access signatures
C. Create a service SAS
D. Create a stored access policy
ANSWER14:
B and D
Notes: A Shared Access Signature (SAS) allows you to have granular control over your storage account, including access to only certain services (i.e. Azure Blobs) and permitting only read, write, delete, list, add, or create access. A Stored Access Policy allows granular control over a single storage container using a Shared Access Signature (SAS).
Question 15: You have an existing Microsoft Enterprise Agreement (EA) Subscription. You need to ship 34TB of data from an on-premise Windows 2016 server to your Azure storage account. You need to ensure that the data transfer has zero impact on the network, preserves your existing drives and is the fastest and most secure method. What should be your first step to starting the import job?
A. Open a ticket with Microsoft Support
B. Order an Azure Databox via the Azure Portal
C. Start an Import Job via the Azure Portal
D. Prepare your hard drives using the WAImportExport tool
ANSWER15:
B
Notes: This option would be the best, as Azure Data boxsupports Windows 2016 servers, and is secure and reliable.
Question 16: You have data in an AWS S3 Bucket named myS3Bucket and you need to copy all of its contents to a container named container1 in an Azure storage account named companydata. Which command would be most efficient use of getting the data from the S3 bucket to the Azure storage container?

A
Notes: The AzCopy tool can copy directly from an AWS S3 bucket to an Azure Storage Account. source
Question 17: You have the following Azure Storage Accounts in your Subscription: stor1 (BlockBlobStorage) stor2 (FileStorage) stor3 (StorageV2) Which of these storage accounts can be converted to Read-Access Geo-Redundant Storage (RA-GRS) based on their storage account kind? Please select the most appropriate answer.
Question 18: You create an Azure storage account named companystore with a publicly accessible container named container1. You upload a file to container1 named pic1.png. What will be the URL in order to access this blob?
Notes: The URL of the blob, by default will be the storage account name, followed by blob.core.windows.net, the container name, then the name of the blob.
Question 19: You have an Azure subscription named Subscription1. In Subscription1, you have an Azure virtual machine named VM1. Attached to VM1 are two network interface cards. You require a third network interface card with a network bandwidth above 1000 Mbps for your storage area network. What should you do?
A. Create an additional VM in the same subnet and connect to VM1 over the LAN
B. Create a new subnet with a sufficient number of available IP addresses
C. Create a new storage account to store data for VM1
Question 20: You are trying to create a new Azure Kubernetes Service (AKS) cluster from your local workstation. The AKS cluster must contain three nodes and ensure access to the worker nodes in order to troubleshoot the kubelet. You have authenticated to Azure from your local workstation with the Azure CLI. What command will you use to create an AKS cluster named AKS1 with the necessary components inside of the resource group named RG1?
A. az aks create -g RG1 -n AKS1 –generate-ssh-keys –node-count 3
B. az kubernetes create –name AKS1 –group RG1 –nodes 3 –generate-keys
C. az aks create –name AKS1 –resource-group RG1 –nodes 3 –ssh-key-value ~/.ssh/id_rsa.pub
D. az kubernetes create –name AKS1 –resource-group RG1 –nodes 3 –generate-keys
ANSWER20:
A
Notes: The correctcommand to use for creating an AKS cluster is az aks create and the -g and -n values are abbreviated syntax for resource group and name respectively. The --generate-ssh-keys flag will create the SSH keys in order to access the worker nodes. The --node-count flag will ensure that there are three worker nodes in the cluster.
Question 21: VM1 is located in the West US region, and the OS disk is Premium SSD. The size of VM1 is currently Standard_D2s_v3, but you need to change the size to Standard_D2. You are able to select the size from the size blade, but you receive an error message. Why can’t you change the VM size?
A. You need to provide the username and password for the OS to upgrade
B. Standard_D2 does not support premium SSD disks
C. The size Standard_D2 is not available in the West US region
D. You did not shut down (deallocated) VM1 before you change the size
ANSWER21:
B
Notes: Standard_D2 does not support premium disks; therefore, you are unable to change VM1 to this size. A good way to remember which size is available is the s in the size, as the s indicates Premium SSD. See more here: dsv3-series
Question 22: You have an Azure Kubernetes Service (AKS) cluster named AKS1 within the resource group named RG1. You are trying run the command kubectl get all from the Azure Cloud Shell (https://shell.azure.com) to view your cluster resources. You received the error Error from server (BadRequest): the server rejected our request for an unknown reason. You’ve verified that the resources exist and the command is correct. What do you need to do in order to view your cluster resources from the Azure Cloud Shell?
A. Retrieve the access credentials using the command az aks get-credentials --name AKS1 --resource-group RG1
B. Log into the cluster GUI from the Azure Portal
C. Install the kubectl tool
D. Access the Kubernetes Dashboard using the command az aks browse --name AKS1 --resource-group RG1
ANSWER22:
A
Notes: AKS does not have a cluster GUI that is accessible from the Azure Portal. You must use a machine with kubectl installed, or the Azure Cloud Shell.
The kubeconfig is required in order to access the Kubernetes API. You can retrieve the kubeconfig using the az aks get-credentials command.
Question 23: You have a subscription named Subscription1. You create a new Azure VM in your subscription named VM5 running Windows 2012 R2. You try to connect and login to VM5, but you get an error that says “We couldn’t connect to the remote PC. Make sure the PC is turned on and connected to the network, and that remote access is enabled.” You have verified that VM5 is running and has been assigned a public IP address. What change do you need to make in order to successfully connect and login to VM5?
A. Add a rule to the Network Security Group that will allow port 3389
B. Select Reset password from the VM blade
C. Use Network Watcher for detailed connection tracing
D. You need to access the VM from a computer that’s in the same subnet
ANSWER23:
A
Notes: A Network Security Group (NSG) is designed to filter traffic to and from Azure resources, including Azure VMs. Allowing port 3389 from your machine to the Azure VM will address the connection issue. You may reset the password, but being you received the error before attempting to enter your credentials says that it's a connectivity problem, not a credentials problem.
Question 24: Subscription1 contains an Azure VM named VM1 with the following configuration:VM Size: Standard_D2s_v3
Public IP Address: 52.173.36.55
Resource Group: RG1
Availability Zone: None
Location: Japan East
Disk Type: Standard HDD
What are two things you can do to reduce data loss and achieve a 99.9% SLA?
A. Create a recovery services vault and enable replication for VM1
B. Move VM1 to a paired region
C. Place the VM in an availability zone
D. Change the disk type to Premium SSD
ANSWER24:
A and D
Notes: Creating a recovery services vault will allow you to back up the VM to a different region and location. You will enable replication to ensure that VM data and settings are continually replicated to the backup location for simple recovery.
Virtual machines with Premium SSD disks qualify for the 99.9% connectivity SLA.
Question 25: You have created an application that is to be run on Linux containers named ContainerApp1. You’ve created an Azure container instance with an FQDN, but you notice that when the container restarts, all application data is lost. What is the best solution to preserve the data associated with your application?
A. Create a public blob storage container and share the URI with the application
B. Create a storage account and share the SAS with the application
C. Mount an Azure file share as a volume in Azure Container Instances
D. Run the container on a VM, and use the managed disk attached to the VM
ANSWER25:
C
Notes:Azure Container Instancescan mount an Azure file share created with Azure Files. Azure Files offers fully managed file shares hosted in Azure Storage that are accessible via Server Message Block (SMB) protocol. Using an Azure file share with Azure Container Instances provides file-sharing features similar to using an Azure file share with Azure virtual machines.
Question 26: You’ve created a Dockerfile that contains the necessary steps to build an image that you plan to use for your application running as a Web App in App Services named APP1. You have created an Azure Container Registry, which is where you plan to store your images to be used for APP1. What should your next step be?
A. Run the az acr build command
B. Create the App Service Plan
C. Run the docker push command
D. Run the docker login command
ANSWER26:
A
Notes: The az acr build command will build and push your image to an Azure Container Registry all in one command. You should use this if you don't have docker installed, and/or if you don't have the compute resources to build images on your local machine.
Question 27: You have an application that runs on instances in a Virtual Machine Scale Set. The number of instances in the VMSS is at three starting Monday. The minimum number of instances is one, and the maximum is 5 instances. There are two scaling rules for this VMSS:
Rule
Condition
Action
Rule1
CPU > 75%
+1 instance
Rule2
CPU < 25%
-1 instance
Based on the rules above and the chart below, on Wednesday how many instances will there be in our VMSS?
Notes: We start with 3 instances on Monday. Based on the chart we will still be at 3 instances on Tuesday at 12:01 because we have not met a condition for any scaling actions to take place, but then at 13:36 on Tuesday we will scale down an instance due to the CPU% being below 25%. Now we have 2 instances. Then on Wednesday at 12:10 we will be scale-out by one instance because our CPU% has gone above 75%. This gives us three instances on Wednesday.
Question 28: Subscription1 contains an Azure VM named VM1. You have added a data disk to VM1, as well as a new network interface card. You need to create two more Azure VMs just like this one named VM2 and VM3. What is the most efficient way to create VM2 and VM3 that will minimize cost?
A. Backup the VM and recover to a different region
B. Redeploy VM1 with the new disk and NIC and deploy the template to VM2 and VM3
C. Select Export template from VM1 blade, then deploy VM2 and VM3 with that template
D. Create an image from VM1 and use the image to deploy VM2 and VM3
ANSWER28:
C
Notes: Exporting the template from a VM is a quick and easy way to take the existing VM settings and automate future deployments.
Question 29: You have an Azure subscription named Subscription1. You have created a web app named App1 in Subscription1 that is sourced from a git repository named Git1. You need to ensure that every commit to the master branch in Git1 triggers a deployment to a test version of the application before releasing it to production. What are two changes that you must make to App1 to fulfill this requirement?
A. Create a build server with the master branch of Git1 as the trigger
B. Configure custom domains for test and production versions of App1
C. Add a new deployment slot to App1 to release the test version of App1
D. Create a new web app and configure failover settings from test to production
ANSWER29:
A and C
Notes: You have the option of creating a build server natively in App Services by selecting Deployment Center in the App1 blade. This will trigger a build every time a commit is made to the master branch of Git1.
Deployment Slots allow greater flexibility within app services, providing a built-in staging environment for your app, allowing you access to your application without deploying it to production.
Question 30: You plan to create an Azure Web App in the East US region. You need to ensure that this web app scales out with demand, to prevent downtime. You also need to ensure that the data that resides inside of the application will remain secure and never become exposed to anyone outside of the organization. Which App Service plan SKU will you chose that will meet these requirements and also save on cost?
A. FREE
B. B1
C. SHARED
D. I1
ANSWER30:
D
Notes: The I1 SKU allows your app to run on dedicated hardware, and also provides network isolation on top of compute isolation to protect your app. It also provides the maximum scale-out capabilities.
Question 31: VM1 is located in the East US region. You have added a premium SSD data disk to VM1, but the IOPS are not satisfying the needs of your application, how can you change the speed of the disk?
A. Select the disk configuration and increase the size
B. Shut down (Deallocate) the VM
C. Export the disk and convert to VHD
D. Create a new disk and migrate the data
ANSWER31:

Question 32: The NoName Company has just deployed a number of Azure VMs into a specific subnet in an Azure virtual network. They have also implemented a network security plan which includes the use of Azure Firewall. From those newly deployed VMs, the company wants to deny access to the website https://www.microsoft.com. How can you achieve this using their current Azure resources?
A. A network rule
B. Create a route via Route Table to the firewall (as a virtual appliance hop)
C. Configure an application rule on the Azure Firewall that blocks FQDNS www.microsoft.com
D. An Application Gateway
E. A Subnet named AzureFirewallSubnet
F. A VPN Gateway
ANSWER32:
A B C
Notes: A network rule would allow access to an external public DNS service, to lookup the microsoft.com domain name. Creating a route via Route Table to the firewall is required to direct incoming traffic (from the firewall public IP address) to a specific destination.
An application rule allows or blocks an address by URL. This is necessary in order to block https://www.microsoft.com according to the requirements of the company.
Question 33: You need to create an Azure virtual machine named VM1 that requires a static private IP address configured inside the IP address space for the VNet in which the VM resides. How do you configure a static IP address for this Azure VM?
A. After the VM has been created, create a new network interface and configure a static IP address for that network interface
B. After the VM has been created, go to the network interface attached to the VM and change the IP configuration to static assignment
C. When creating a VM in the portal, select New next to private ip address and choose static after assigning the correct IP address
D. When creating the VM in the portal, change the setting from dynamic to static on the networking tab under private IP address
ANSWER33:
B
Notes: Changing the IP configuration on the network interface will achieve this goal.
Question 34: You have an Azure subscription named Subscription1. In Subscription1, you have a web server that has the IP address 10.1.0.83 and a database server that has the IP address 10.1.0.142. Instead of remembering the IP addresses of the servers, you’d like to connect to these servers using a DNS name. With no DNS server currently, and without having to create a new DNS server, how can you access your database server from your web server by the DNS name db.yourcompany.com?
A. Public DNS Zone
B. Promote Server to Domain Controller
C. Access the Domain Controller
D. Private DNS Zone
ANSWER34:
D
Notes: A private DNS zone is an easy way to register servers with a DNS name versus having to access them by their IP address
Question 35: You have an Azure subscription named Subscription1. In Subscription1 you have two VNets, one named VNet-Hub and one named VNet-Spoke. Within VNet-Hub, there is an Azure Firewall with a public IP address, configured as a Standard SKU. In VNet-Spoke, there is a Windows Server 2016 with no public IP address and no Network Security Group (NSG). Using which three items can you utilize the public IP address of the Azure firewall to connect to the Windows Server, without exposing the server to the public internet directly?
A. NAT Rule for the Firewall
B. Route Table
C. Virtual Network Gateway
D. Virtual Network Peering
E. ExpressRoute Gateway
ANSWER35:
A B D
Notes: You can configure a NAT rule on the firewall to translate and filter inbound Internet traffic to your subnets. You will need a route table to route ingress traffic to the firewall virtual appliance. In order for traffic to flow from the VNet-Spoke to VNet-Hub, you will need a peer connection between the virtual networks (Virtual Network Peering).
Question 36: You have an on-premises environment as well as your Azure environment with a subscription named Subscription1. Subscription1 has a virtual network named VNET1 and you need to connect to the on-premises network securely using an ExpressRoute link and Site-to-site VPN. What Azure resources do you need in order to establish the connection while minimizing cost?
A. Azure VPN Gateway
B. Network virtual appliance
C. No resources needed, ExpressRoute is encrypted by default
D. A route table
ANSWER36:
B and D
Notes: VPN tunnels over Microsoft peering can be terminated either using VPN gateway, or using an appropriate Network Virtual Appliance (NVA) available through Azure Marketplace. We choose to use NVA because it accomplishes our goal, but for a lesser cost than Azure VPN Gateway. A route table is required to specify the next hop for traffic coming and going from the on-premises network.
Question 37: You have a Network Security Group (NSG) that is associated with a network interface that is attached to an Azure virtual machine named VM1 running Windows Server 2019. VM1 is in subnet named subnet1, in a virtual network named VNet1. A different NSG is attached to subnet1, but you notice that there is an inbound rule to allow port 3389. When you try to connect to VM1, you cannot connect. You reviewed the NSG and the source IP address and the protocol are correct. How can you connect to VM1 using best practices for NSGs in Azure?
A. The protocol on the NSG rule is set to UDP
B. The NSG attached to the network interface needs to be removed
C. The source IP address on the NSG rule is incorrect
D. You need to add an inbound rule for the NSG attached to the network interface
ANSWER37:
B
Notes: Removing the NSG from the network interface would allow the VM to use the NSG associated with the subnet, which is best practice.
Question 38: You have an Azure subscription named Subscription1. In Subscription1 you have an Azure VM named VM1 with Windows Server 2019 as the operating system. VM1 does not have a public IP address assigned to it. VM1 is located in a virtual network named VNet1, in subnet1. Attached to subnet1 is a Network Security Group (NSG) that has port 3389 open inbound. On your local machine, you do not have an RDP client installed, but you need to login into the VM. Without assigning a public IP address to the VM, what three things in combination can we use to log into VM1?
A. HTML5 supported Web Browser
B. Azure VPN Gateway
C. A subnet named AzureBastionSubnet
D. A Gateway Subnet
E. Azure Bastion Host
F. Inbound security rule to open port 443
ANSWER38:
A C E
Notes: The RDP connection to the virtual machine happens via Bastion host using the Azure portal (over HTML5) using port 443 and the Bastion service.
The subnet inside your virtual network to which the Bastion resource will be deployed must have the name AzureBastionSubnet. The name lets Azure know which subnet to deploy the Bastion resource to. This is different than a Gateway Subnet.
The Azure Bastion service is a new fully platform-managed PaaS service that you provision inside your virtual network. It provides secure and seamless RDP/SSH connectivity to your virtual machines directly in the Azure portal over TLS. When you connect via Azure Bastion, your virtual machines do not need a public IP address.
Question 39: You have a subscription named Subscription1. Subscription1 has two virtual networks named VNet1 and VNet2 in two different resource groups. VNet1 is located in the West US region and VNet2 is located in the East US region. You need to apply a network security group named NSG1 to a subnet in VNet1. NSG1 is located in the East US region. How do you attach NSG1 to the subnet in VNet1?
A. You can’t. Create a new network security group in the west us region
B. Move VNet1 into a resource group located in the east us region
C. Select the subnet and choose NSG1 from the network security group drop-down
D. Move NSG1 into the VNet1 resource group
ANSWER39:
A
Notes: In order for you to associate a network security group to a subnet, both the virtual network and the network security group must be in the same region.
Question 40: You have a subscription named Subscription1. Subscription1 has one Azure virtual machine named VM1 which is an Ubuntu server. You can’t seem to login to the server via SSH. What tool should you use to verify if the problem is the network security group?
A. IP flow verify tool in Azure Network Watcher
B. Azure Monitor VM metrics
C. Azure Traffic Manager traffic view
D. Azure Virtual Network logs
ANSWER40:
A
Notes: The IP Flow Verify tool checks if a packet is allowed or denied to or from a virtual machine. The information consists of direction, protocol, local IP, remote IP, local port, and a remote port. If the packet is denied by a security group, the name of the rule that denied the packet is returned.
Question 41: You have two Azure virtual machines named VM1 and VM2. VM1 is using the Red Hat Enterprise Linux 8.1 (LVM) operating system and is located in VNet1, within subnet1. VM2 is using the Windows Server 2019 operating system, and is located in VNet1, within subnet2. VNet1 has custom DNS configured, pointing to a DNS server with the IP address 172.168.0.6. VM2 has 10.0.1.15 configured as the DNS server on its network interface. Which DNS server will VM2 use for DNS queries?
A. 8.8.8.8
B. 10.0.1.15 for primary, 172.168.0.6 as secondary
C. 10.0.1.15
D. 172.168.0.6
ANSWER41:
C
Notes: Since the network interface attached to VM2 is assigned to a specific DNS server, it takes precedence over the DNS configured on the VNet.
Question 42: You have created a new Azure virtual machine in a subnet named Subnet1 with an attached network interface card named NIC1. The NIC1, attached to Subnet1, has the following effective routes:
Question 43: You have a standard load balancer that directs traffic from port 80 externally to three different virtual machines. You need to direct all incoming TCP traffic on port 5000 to port 22 internally for connecting to Linux VMs. What do you need in order to connect to the VM via SSH?
A. A public IP address for all three VMs
B. A Route Table with at least one rule
C. A Network Security Group (NSG)
D. A Network Address Translation (NAT) Rule
ANSWER43:
C and D
Notes: The NSG rules work alongside the NAT rules to provide a connection to a VM that's behind a load balancer. NAT rules work alongside NSG rules to provide a connection to a VM that's behind a load balancer.
Question 44: You have a web application that serves video and images to those visiting the site. You start to notice that your web server is overloaded, and often crashes because the requests have consumed all of its resources. To combat this, you’ve added an additional web server and you plan to load balance these servers by serving images from the first server only and serving video from the second server only. Which Azure resource can you implement that will properly load balance (at OSI layer 7) with URL-based routing and secure with SSL at the lowest cost?
A. Azure Load Balancer
B. Azure Front Door
C. Azure Application Gateway
D. Web Application Firewall
ANSWER44:
C
Notes: Azure Application Gateway operates at layer 7 (the application layer), and is a web traffic load balancer that enables you to manage traffic to your web applications. Application Gateway can make routing decisions based on URI path and secure with SSL.
Question 45: You manage a virtual network named VNet1 that is hosted in the West US region. Two virtual machines named VM1 and VM2, both running Windows Server, are on VNet1. You need to monitor traffic between VM1 and VM2 for a period of five hours. As a solution, you propose to create a connection monitor in Azure Network Watcher. Does this solution meet the goal?
A. Yes
B. –
C. –
D. No
ANSWER45:
A
Notes: The connection monitor capability in Azure Network Watcher monitors communication at a regular interval and informs you of reachability, latency, and network topology changes between the VM and the endpoint.
Question 46: You have an Azure subscription named Subscription1. You would like to connect your on-premises environment to Subscription1. You have to meet three requirements from the business. The first requirement is that the connection from the on-premises office and Azure must be a private connection. No network traffic is allowed to go over the public internet. The second requirement is that all traffic from the on-premises office and Azure must happen at layer 3 (network layer). The third requirement is that this connection from on-premises to Azure must be redundant to minimize the opportunity for failure. What type of connection fulfills these three requirements?
A. ExpressRoute with premium add-on
B. ExpressRoute
C. Site-to-Site VPN
D. Virtual WAN
ANSWER46:
B
Notes:ExpressRoute lets you extend your on-premises networks into the Microsoft cloud over a private connection facilitated by a connectivity provider. ExpressRoute connections do not go over the public Internet. An ExpressRoute Connection is a layer 3 connection between your on-premises network and Azure through a connectivity provider (e.g. Verizon).
Question 47: You have an Azure subscription as well as an on-premises environment that is connected via ExpressRoute circuit. You have two additional branch offices that you need to connect to the network, as well as ten remote employees that change locations frequently but still need access to Azure resources. What is the solution that will provide the quickest setup at the lowest cost?
A. Site-to-Site VPN
B. Point-to-Site VPN
C. Virtual WAN
D. Hub-and-Spoke Network Topology
ANSWER47:
C
Notes: The Virtual WAN architecture is a hub and spoke architecture for branches and users. It enables global transit network architecture, where the cloud-hosted network 'hub' enables transitive connectivity between endpoints that may be distributed across different types of 'spokes'. All hubs are connected in full mesh in a Standard Virtual WAN making it easy for the user to use the Microsoft backbone for any-to-any (any spoke) connectivity. This satisfies the requirement to provide the quickest set up at the lowest cost.
Question 48: You have a small number of servers running a microservice, and you want to make sure that all the servers have connectivity to each other.

A. Log Analytics Workspace
B. Network Performance Monitor
C. Azure Monitor
D. Azure Traffic Manager
ANSWER48:
A and B
Notes:A Log Analytics workspace is a data repository for Azure Monitor log data. A pre-requisite in order to use Network Performance Monitor. Network Performance Monitor helps you monitor network performance between various points in your network infrastructure. It also helps you monitor network connectivity to service and application endpoints and monitor the performance of Azure ExpressRoute.
Question 49: You have two virtual networks named VNet1 and VNet2. VNet1 is located in the West US region, whereas VNet2 is located in the East US region. You need to configure a virtual machine that’s located in VNet1 to also communicate with VMs in VNet2. From the choices available how can we enable communication between resources in VNet1 and VNet2
A. Migrate the VNet1 VM to VNet2 and leave the other VM components on VNet1
B. Migrate the network interface card (NIC), the network security group (NSG) and the VM disks to VNet2
C. Just the VM disks will need to be migrated to VNet2
D. Configure a VNet-to-VNet VPN gateway connection to allow communication between VNets in different regions
Question 50: You have two subscriptions, one named Subscription1 and the other named Subscription2. Both subscriptions are located within the same tenant. You have one Azure virtual machine located within Subscription1 and another Azure virtual machine within Subscription2 and you’d like to view CPU utilization metrics on both virtual machines. How can you achieve this while maintaining the minimum number of Azure resources and minimizing cost?
A. Create a Log Analytics Workspace for both VMs
B.Turn on VM Insights in Azure Monitor
C. Install the Log Analytics (OMS) Agent on the VMs
D. Enable guest-level monitoring on each VM
ANSWER50:
A and B
Notes: You can view metrics data (such as CPU utilization %) over time by sending your metrics data to a log analytics workspace. This workspace can collect metrics data from multiple VMs, no matter if they are located in the same or different subscriptions.
VM integration with Azure Monitor Logs delivers powerful aggregation and filtering, allowing Azure Monitor for VMs to analyze data trends over time. You can view this data in a single VM from the virtual machine directly, or you can use Azure Monitor to deliver an aggregated view of your VMs where the view supports Azure resource-context or workspace-context modes.
Question 51: You have created a new Azure virtual machine named VM1. You plan to use VM1 as a web server, which will require the VM to be accessible using HTTP/S (HTTP and HTTPS) protocol. A Network Security Group (NSG) is attached to the NIC of VM1 with the following rules:
What changes do you have to make to the NSG in order to meet the requirements for VM1?
A. Change the priority of Rule3 to 200
B. Change the action of Rule1 to Allow
C. Change the priority of Rule4 to 200
D. Change the port of Rule5 to 443
ANSWER51:
C
Notes: Lower priority rules take precedence over higher ones. Changing Rule4 to a lower number will negate all the other rules of a lesser priority, therefore allowing traffic on ports 60-500, which includes 80 and 443, the ports necessary for allowing traffic over HTTP/S. Remember the lower the priority the priority number the higher the priority in regards to reading the rules.
Question 52: You have an Azure virtual machine running Windows Server 2016. You need to collect OS level metrics on this virtual machine, including Windows event logs and performance counters. Which of the following items do you need in order to collect this metrics data?
A. Enable guest-level monitoring
B. Windows Diagnostics Extension
C. Log Analytics Agent
D. InfluxData Telegraf Agent
E. Storage Account for Diagnostic Data
ANSWER52:
A B E
Notes: In order to install the diagnostics extension on an Azure VM, you must enable guest-level monitoring from the VM settings in the portal. Windows Diagnostic Extension is an agent in Azure Monitor that collects monitoring data from the guest operating system and workloads of Azure virtual machines and other compute resources. In order to enable guest-level monitoring, you need to create a storage account for storing the metrics data.
Question 53: You have an Azure subscription with a virtual machine named VM1. You are using Recovery Services Vault (RSV) to backup VM1 with soft delete enabled. The backup policy is set to backup daily at 11 PM UTC, retain an instant recovery snapshot for 2 days, and retain the daily backup point for 14 days. After the initial backup of VM1, you are instructed to delete the vault and all of the backup data. What should you do?
A. Turn off soft delete in the vault security settings
B. Wait 14 days
C. Stop the backup of VM1 and delete backup data
D. Delete the backup policy
E. Delete Backup Jobs Workload
F. Wait 15 days
ANSWER53:
A and C
Notes: When you stop the backup and delete the backup data, because you have soft delete enabled, the backup data is still kept. Permanently delete the soft-deleted backup items that would remove the backup data indefinitely. If you stop the backup of VM1 and choose delete backup data from the dropdown menu, this will stop future backups and delete the existing backup data.
Question 54: You have a number of virtual machines and web applications running in your Azure environment. These Azure resources are critical for business operations, so you’ve locked the resources in order to prevent deletion. In addition, how can you alert on these actions in the portal, and notify your team via email and SMS when a user is trying to delete or create a new resource from within your Azure subscription?
A. Pin the activity log to your dashboard
B. Create a new alert rule
C. Query Administrative Events and Copy Link to Query
D. Create a new action group
ANSWER54:
B and D
Notes: Alert rules specify the conditions for which the alert is triggered. Activity log alerts are the alerts that get activated when a new activity log event occurs that matches the conditions specified in the alert. An action group is a collection of notification preferences defined by the owner of an Azure subscription. Azure Monitor and Service Health alerts use action groups to notify users that an alert has been triggered.
Question 55: You have a .NET Core application running in Azure App Services. You are expecting a huge influx of traffic to your application in the coming days. When your application experiences this spike in traffic, you want to detect any anomalies such as request errors or failed queries immediately.

A. Client-side monitoring
B. Live Metrics Stream in Application Insights
C. Application Insights Search
D. Log analytics workspace
ANSWER55:
B
Notes: Live metrics stream includes such information as the number of incoming requests, the duration of those requests, and any failures that occur. You can also inspect critical performance metrics such as processor and memory.
Question 56: You have an Azure subscription named Subscription1. In Subscription1 you have two Azure VMs named VM1 and VM2, both running Windows Server 2016. VM1 is backed up using Recovery Services Vault, with a backup policy of producing a daily backup and keeping that daily backup for seven days. Also, a snapshot is kept for 2 days. VM1 is compromised by a virus that infects the entire system, including the files. You need to restore the files from yesterday’s backup of VM1. Where can you restore the files to in the quickest manner?
A. A new Azure VM
B. Restore the VM1 snapshot
C. VM2
D. In-place
ANSWER56:
B
Notes: Using snapshots for VM backups, you speed up the recovery time considerably. The snapshots are stored with the disks in Azure, so the transfer speeds are optimal.
Question 57: You have a subscription named Subscription1. You would like to be alerted upon certain administrative events within Subscription1 to detect unauthorized access. Which of the following is the quickest method to setup these types of alerts?
A. Monitor > Alerts > New Alert Rule
