How do I set up Failover on Amazon AWS Route53?

In simple configurations, you create a group of records that all have the same name and type, such as a group of weighted records with a type of A for example.com. In more complex configurations, you create a tree of records that route traffic based on multiple criteria. Read more …

• How can a program running inside AWS EC2 determine which VPC and security group an incoming IP address or TCP connection belongs to, for application-layer firewalling?

  I assume it is your subscription where the VPCs are located, otherwise you can’t really discover the information you are looking for. On the EC2 server you could use AWS CLI or Powershell based scripts that query the IP information. Based on IP you can find out what instance uses the network interface, what security groups are tied to it and in which VPC the instance is hosted. Read more here…

   

• What are some tips, tricks and gotchas when using AWS Lambda to connect to a VPC?

  When using AWS Lambda inside your VPC, your Lambda function will be allocated private IP addresses, and only private IP addresses, from your specified subnets. This means that you must ensure that your specified subnets have enough free address space for your Lambda function to scale up to. Each simultaneous invocation needs its own IP. Read more here…

How do AWS step functions communicate with lambda functions which are in a VPC?

When a Lambda “is in a VPC”, it really means that its attached Elastic Network Interface is the customer’s VPC and not the hidden VPC that AWS manages for Lambda.

The ENI is not related to the AWS Lambda management system that does the invocation (the data plane mentioned here). The AWS Step Function system can go ahead and invoke the Lambda through the API, and the network request for that can pass through the underlying VPC and host infrastructure.

Those Lambdas in turn can invoke other Lambda directly through the API, or more commonly by decoupling them, such as through Amazon SQS used as a trigger. Read more ….

How do I invoke an AWS Lambda function programmatically?

public InvokeResult invoke(InvokeRequest request)

Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. To invoke a function asynchronously, set InvocationType to Event.

For synchronous invocation, details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log and trace.

When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Retry Behavior.

For asynchronous invocation, Lambda adds events to a queue before sending them to your function. If your function does not have enough capacity to keep up with the queue, events may be lost. Occasionally, your function may receive the same event multiple times, even if no error occurs. To retain events that were not processed, configure your function with a dead-letter queue.

The status code in the API response doesn’t reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, limit errors, or issues with your function’s code and configuration. For example, Lambda returns TooManyRequestsException if executing the function would cause you to exceed a concurrency limit at either the account level ( Concurrent Invocation Limit Exceeded) or function level ( Reserved Function Concurrent Invocation LimitExceeded).

For functions with a long timeout, your client might be disconnected during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.

This operation requires permission for the lambda:InvokeFunction action. Read more…

How bad would it be to configure one AWS VPC for all my environments (dev, stg, prod) while creating 2 subnets (priv, pub) for each environment?  It depends highly on the budget. However, for my systems I always set different environments up in different VPCs. Why? Because they’re guaranteed to be isolated from one another, and VPCs are very easy to create and manage if you’ve automated. The flip side is you do pay a bit more for edge services like NAT Gateway and ALB, since you’ll have at least one per VPC.

 

What are the differences between default and non-default AWS VPCs?

Default VPC

1. 1 per region
2. a set VPC CIDR range … you can’t changed it
3. has everything configured by default .. 1 subnet per AZ, an internet gateway, routes and subnets set to allocate IPv4 by default.

Custom VPCs

1. As any as you want per region (within limits)
2. Customisable CIDR range
3. Customisable subnet structure
4. Nothing configured by default, you have to configure everything

What would be the effect if IPv4 stopped working suddenly, and only IPv6 was left standing?

if IPv4 stopped working, and IPv6 remained functional, through some magical means that prevented IPv4 from being fixed, there would be a few days of pandemonium while non-dual-stack networks and legacy IPv4-only networks flailed mightily, and then a whole bunch of IPv6-skilled network engineers would make a shit-ton of money in a short period of time going from ill-prepared network to ill-prepared network, one at a time, rolling out IPv6 across their infrastructure as quickly as possible. Read more here….

 

Why is the subnet mask important in determining the network address?

The subnet mask determines how many bits of the network address are relevant (and thus indirectly the size of the network block in terms of how many host addresses are available) –

192.0.2.0, subnet mask 255.255.255.0 means that 192.0.2 is the significant portion of the network number, and that there 8 bits left for host addresses (i.e. 192.0.2.0 thru 192.0.2.255)

192.0.2.0, subnet mask 255.255.255.128 means that 192.0.2.0 is the significant portion of the network number (first three octets and the most significant bit of the last octet), and that there 7 bits left for host addresses (i.e. 192.0.2.0 thru 192.0.2.127)

When in doubt, envision the network number and subnet mask in base 2 (i.e. binary) and it will become much clearer. Read more here…

 

What are some best practices securing my Amazon Virtual Private Cloud (VPC)?

IAM is the new perimeter.

Separate out the roles needed to do each job. (Assuming this is a corporate environment)

Have a role for EC2, another for Networking, another for IAM.

Everyone should not be admin. Everyone should not be able to add/remove IGW’s, NAT gateways, alter security groups and NACLS, or setup peering connections.

Also, another thing… lock down full internet access. Limit to what is needed and that’s it. Read more here….

How can we setup AWS public-private subnet in VPC without NAT server?

Within a single VPC, the subnets’ route tables need to point to each other. This will already work without additional routes because VPC sets up the local target to point to the VPC subnet.

Security groups are not used here since they are attached to instances, and not networks.

See: Amazon Virtual Private Cloud

The NAT EC2 instance (server), or AWS-provided NAT gateway is necessary only if the private subnet internal addresses need to make outbound connections. The NAT will translate the private subnet internal addresses to the public subnet internal addresses, and the AWS VPC Internet Gateway will translate these to external IP addresses, which can then go out to the Internet. Read more here ….

What are the applications (or workloads) that cannot be migrated on to cloud (AWS or Azure or GCP)?

A good example of workloads that currently are not in public clouds are mobile and fixed core telecom networks for tier 1 service providers. This is despite the fact that these core networks are increasingly software based and have largely been decoupled from the hardware. There are a number of reasons for this such as the public cloud providers such as Azure and AWS do not offer the guaranteed availability required by telecom networks. These networks require 99.999% availability and is typically referred to as telecom grade.

The regulatory environment frequently restricts hosting of subscriber data outside the of the operators data centers or in another country and key network functions such as lawful interception cannot contractually be hosted off-prem. Read more here….

How many CIDRs can we add to my own created VPC?

You can add up to 5 IPv4 CIDR blocks, or 1 IPv6 block per VPC. You can further segment the network by utilizing up to 200 subnets per VPC. Amazon VPC Limits. Read more …

Why can’t a subnet’s CIDR be changed once it has been assigned?

Sure it can, but you’ll need to coordinate with the neighbors. You can merge two /25’s into a single /24 quite effortlessly if you control the entire range it covers. In practice you’ll see many tiny allocations in public IPv4 space, like /29’s and even smaller. Those are all assigned to different people. If you want to do a big shuffle there, you have a lot of coordinating to do.. or accept the fallout from the breakage you cause. Read more…

Can one VPC talk to another VPC?

Yes, but a Virtual Private Cloud is usually built for the express purpose of being isolated from unwanted external traffic. I can think of several good reasons to encourage that sort of communication, so the idea is not without merit. Read more..

What questions to expect in cloud support engineer deployment roles at AWS? 

Cloud Support Engineer (CSE) is a role which requires the following abilities:

• Wide range of technical skills
• Good communication and time management
• Good knowledge about the AWS services, and how to leverage them to solve simple to complex problems.

As your question is related to the deployment Pod, you will probably be asked about deployment methods (A/B testing like blue-green deployment) as well as pipelining strategies. You might be asked during this interview to reason about a simple task and to code it (like parsing a log file). Also review the TCP/IP stack in-depth as well as the tools to troubleshoot it for the networking round. You will eventually have some Linux questions, the range of questions can vary from common CLI tools to Linux internals like signals / syscalls / file descriptors and so on.

Last but not least the Leadership principles, I can only suggest you to prepare a story for each of them. You will quickly find what LP they are looking for and would be able to give the right signal to your interviewer.

Finally, remember that theres a debrief after the (usually 5) stages of your on site interview, and more senior and convincing interviewers tend to defend their vote so don’t screw up with them.

Be natural, focus on the question details and ask for confirmation, be cool but not too much. At the end of the day, remember that your job will be to understand customer issues and provide a solution, so treat your interviewers as if they were customers and they will see a successful CSE in you, be reassured and give you the job. 

Expect questions on cloudformations, Teraform, Aws ec2/rds and stack related questions.

Its a high tech call center. You are expected to take calls, chats of customers and give them technical advice. You will not be doing any of the cool stuff you did earlier (if you are coming from engineering job or DBA). You will surely gain a very good knowledge of multiple AWS services and the one that you will be hired in, however most of the knowledge will be theoretical and nothing practical in day-to-day life.

It also depends on the support team you are being hired for. Networking or compute teams (Ec2) have different interview patterns vs database or big data support.

In any case, basics of OS, networking are critical to the interview. If you have a phone screen, we will be looking for basic/semi advance skills of these and your speciality. For example if you mention Oracle in your resume and you are interviewing for the database team, expect a flurry of those questions.

Other important aspect is the Amazon leadership principles. Half of your interview is based on LPs. If you fail to have scenarios where you do not demonstrate our LPs, you cannot expect to work here even though your technical skills are above average (Having extraordinary skills is a different thing).

The overall interview itself will have 1 phone screen if you are interviewing in the US and 1–2 if outside US. The onsite loop will be 4 rounds , 2 of which are technical (again divided into OS and networking and the specific speciality of the team you are interviewing for ) and 2 of them are leadership principles where we test your soft skills and management skills as they are very important in this job. You need to have a strong view point, disagree if it seems valid to do so, empathy and be a team player while showing the ability to pull off things individually as well. These skills will be critical for cracking LP interviews.

You will NOT be asked to code or write queries as its not part of the job, so you can concentrate on the theoretical part of the subject and also your resume. We will grill you on topics mentioned on your resume to start with.

Traditional monolithic architectures are hard to scale: TRUE

Monolithic architecture is something that build from single piece of material, historically from rock. Monolith term normally use for object made from single large piece of material.” – Non-Technical Definition. “Monolithic application has single code base with multiple modules.

Large Monolithic code-base (often spaghetti code) puts immense cognitive complexity on the developer’s head. As a result, the development velocity is poor. Granular scaling (i.e., scaling part of the application) is not possible. Polyglot programming or polyglot database is challenging.

Drawbacks of Monolithic Architecture

This simple approach has a limitation in size and complexity. Application is too large and complex to fully understand and made changes fast and correctly. The size of the application can slow down the start-up time. You must redeploy the entire application on each update.

18. Sticky Sessions help increase your application’s scability: FALSE

Sticky sessions, also known as session affinity, allow you to route a site user to the particular web server that is managing that individual user’s session. The session’s validity can be determined by a number of methods, including a client-side cookies or via configurable duration parameters that can be set at the load balancer which routes requests to the web servers.

Some advantages with utilizing sticky sessions are that it’s cost effective due to the fact you are storing sessions on the same web servers running your applications and that retrieval of those sessions is generally fast because it eliminates network latency. A drawback for using storing sessions on an individual node is that in the event of a failure, you are likely to lose the sessions that were resident on the failed node. In addition, in the event the number of your web servers change, for example a scale-up scenario, it’s possible that the traffic may be unequally spread across the web servers as active sessions may exist on particular servers. If not mitigated properly, this can hinder the scalability of your applications. Read more here … 

AWS recommends replicating across Availability Zones for resiliency: TRUE

If you need to replicate your data or applications in an AWS Local Zone, AWS recommends that you use one of the following zones as the failover zone:

• Another Local Zone

• An Availability Zone in the Region that is not the parent zone. You can use the describe-availability-zones command to view the parent zone.

For more information about AWS Regions and Availability Zones, see AWS Global Infrastructure.

What are the benefits of AWS Cloud Computing?

• Trade Capital expenses for variable expenses
• Increase speed and agility
• Benefit from massive economies at scale
• Stop spending money on running and maintaining data centers
• Stop guessing capacity
• Go global in minutes

What is the default behavior for an EC2 instance when terminated?

After you terminate an instance, it remains visible in the console for a short while, and then the entry is automatically deleted. You cannot delete the terminated instance entry yourself. After an instance is terminated, resources such as tags and volumes are gradually disassociated from the instance, therefore may no longer be visible on the terminated instance after a short while.

When an instance terminates, the data on any instance store volumes associated with that instance is deleted.

By default, Amazon EBS root device volumes are automatically deleted when the instance terminates. However, by default, any additional EBS volumes that you attach at launch, or any EBS volumes that you attach to an existing instance persist even after the instance terminates. This behavior is controlled by the volume’s DeleteOnTermination attribute, which you can modify

For more information, please visit: Terminate Your Instance

How do Amazon EC2 EBS burst credits work?

The documentation on General Purpose SSD (gp2) EBS volumes can be found at this page: New SSD-Backed Elastic Block Storage 

When you first launch an instance with gp2 volumes attached, you get an initial burst credit allowing for up to 30 minutes of 3,000 iops/sec.

After the first 30 minutes, your volume will accrue credits as follows (taken directly from AWS documentation):

Within the General Purpose (SSD) implementation is a Token Bucket model that works as follows

• Each token represents an “I/O credit” that pays for one read or one write.
• A bucket is associated with each General Purpose (SSD) volume, and can hold up to 5.4 million tokens.
• Tokens accumulate at a rate of 3 per configured GB per second, up to the capacity of the bucket.
• Tokens can be spent at up to 3000 per second per volume.
• The baseline performance of the volume is equal to the rate at which tokens are accumulated — 3 IOPS per GB per second.

In addition to this, gp2 volumes provide baseline performance of 3 iops per Gb, up to 1Tb (3000 iops). Volumes larger than 1Tb no longer work on the credit system, as they already provide a baseline of 3000 iops. Gp2 volumes have a cap of 10,000 iops regardless of the volume size (so the iops max out for volumes larger than 3.3Tb)

Is elastic IP service free if we associate it with any VM (EC2 server)?

Elastic IP addresses are free when you have them assigned to an instance, feel free to use one! Elastic IPs get disassociated when you stop an instance, so you will get charged in the mean time. The benefit is that you get to keep that IP allocated to your account though, instead of losing it like any other. Once you start the instance you just re-associate it back and you have your old IP again.

Here are the changes associated with the use of Elastic IP addresses

No cost for Elastic IP addresses while in use

* $0.01 per non-attached Elastic IP address per complete hour

* $0.00 per Elastic IP address remap – first 100 remaps / month

* $0.10 per Elastic IP address remap – additional remap / month over 100

If you require any additional information about pricing please reference the link below

Amazon EC2 Pricing – Amazon Web Services

The other cost are as outlined in the paragraph you have quoted.

How do I reduce my AWS EC2 cost? My AWS EC2 expenditure comprises 80% of my AWS bill.

The short answer to reducing your AWS EC2 costs – turn off your instances when you don’t need them.

Your AWS bill is just like any other utility bill, you get charged for however much you used that month. Don’t make the mistake of leaving your instances on 24/7 if you’re only using them during certain days and times (ex. Monday – Friday, 9 to 5).

To automatically start and stop your instances, AWS offers an “EC2 scheduler” solution. A better option would be a cloud cost management tool that not only stops and starts your instances automatically, but also tracks your usage and makes sizing recommendations to optimize your cloud costs and maximize your time and savings.

You could potentially save money using Reserved Instances. But, in non-production environments such as dev, test, QA, and training, Reserved Instances are not your best bet. Why is this the case? These environments are less predictable; you may not know how many instances you need and when you will need them, so it’s better to not waste spend on these usage charges. Instead, schedule such instances (preferably using ParkMyCloud). Scheduling instances to be only up 12 hours per day on weekdays will save you 65% – better than all but the most restrictive 3-year RIs!

You can also save money with:

• Spot Instances
• AWS Dedicated Hosts & Dedicated Instances
• Auto Scaling Groups
• Rightsizing

What is the difference between an Instance, AMI and Snaphots in AWS? What are they used for?

Well AWS is a web service provider which offers a set of services related to compute, storage, database, network and more to help the business scale and grow

All your concerns are related to AWS EC2 instance, so let me start with an instance

Instance:

• An EC2 instance is similar to a server where you can host your websites or applications to make it available Globally
• It is highly scalable and works on the pay-as-you-go model
• You can increase or decrease the capacity of these instances as per the requirement

AMI:

• AMI provides the information required to launch the EC2 instance
• AMI includes the pre-configured templates of the operating system that runs on the AWS
• Users can launch multiple instances with the same configuration from a single AMI

Snapshot:

• Snapshots are the incremental backups for the Amazon EBS
• Data in the EBS are stored in S3 by taking point-to-time snapshots
• Unique data are only deleted when a snapshot is deleted
• Multiple EBS can be created using these snapshots

What are the main differences between a VPNs, VPS and VPC?

They are definitely all chalk and cheese to one another.

A VPN (Virtual Private Network) is essentially an encrypted “channel” connecting two networks, or a machine to a network, generally over the public internet.

A VPS (Virtual Private Server) is a rented virtual machine running on someone else’s hardware. AWS EC2 can be thought of as a VPS, but the term is usually used to describe low-cost products offered by lots of other hosting companies.

A VPC (Virtual Private Cloud) is a virtual network in AWS (Amazon Web Services). It can be divided into private and public subnets, have custom routing rules, have internal connections to other VPCs, etc. EC2 instances and other resources are placed in VPCs similarly to how physical data centers have operated for a very long time.

What is the use of elastic IP in AWS?

Elastic IP address is basically the static IP (IPv4) address that you can allocate to your resources.

Now, in case that you allocate IP to the resource (and the resource is running), you are not charged anything. On the other hand, if you create Elastic IP, but you do not allocate it to the resource (or the resource is not running), then you are charged some amount (should be around $0.005 per hour if I remember correctly)

Additional info about these:

You are limited to 5 Elastic IP addresses per region. If you require more than that, you can contact AWS support with a request for additional addresses. You need to have a good reason in order to be approved because IPv4 addresses are becoming a scarce resource.

In general, you should be good without Elastic IPs for most of the use-cases (as every EC2 instance has its own public IP, and you can use load balancers, as well as map most of the resources via Route 53).

One of the use-cases that I’ve seen where my client is using Elastic IP is to make it easier for him to access specific EC2 instance via RDP, as well as do deployment through Visual Studio, as he targets the Elastic IP, and thus does not have to watch for any changes in public IP (in case of stopping or rebooting).

Why would you choose not to use AWS Transit Gateway instead of VPC peering?

At this time, AWS Transit Gateway does not support inter region attachments. The transit gateway and the attached VPCs must be in the same region. VPC peering supports inter region peering.

Difference between AWS Workspace and AWS Ec2 VM?

• The EC2 instance is server instance whilst a Workspace is windows desktop instance

• Both Windows Server and Windows workstation editions have desktops. Windows Server Core doesn’t not (and AWS doesn’t have an AMI for Windows Server Core that I could find).

• It is possible to SSH into a Windows instance – this is done on port 22. You would not see a desktop when using SSH if you had enabled it. It is not enabled by default.

• If you are seeing a desktop, I believe you’re “RDPing” to the Windows instance. This is done with the RDP protocol on port 3389.

• Two different protocols and two different ports.
• Workspaces doesn’t allow terminal or ssh services by default. You need to use Workspace client. You still can enable RDP or/and SSH but this is not recommended.
• Workspaces is a managed desktop service. AWS is taking care of pre-build AMIs, software licenses, joining to domain, scaling etc.
• What is Amazon EC2? Scalable, pay-as-you-go compute capacity in the cloud. Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.
• What is Amazon WorkSpaces? Easily provision cloud-based desktops that allow end-users to access applications and resources. With a few clicks in the AWS Management Console, customers can provision a high-quality desktop experience for any number of users at a cost that is highly competitive with traditional desktops and half the cost of most virtual desktop infrastructure (VDI) solutions. End-users can access the documents, applications and resources they need with the device of their choice, including laptops, iPad, Kindle Fire, or Android tablets.
• Amazon EC2 can be classified as a tool in the “Cloud Hosting” category, while Amazon WorkSpaces is grouped under “Virtual Desktop”.

• Some of the features offered by Amazon EC2 are:

  • Elastic – Amazon EC2 enables you to increase or decrease capacity within minutes, not hours or days. You can commission one, hundreds or even thousands of server instances simultaneously.
  • Completely Controlled – You have complete control of your instances. You have root access to each one, and you can interact with them as you would any machine.
  • Flexible – You have the choice of multiple instance types, operating systems, and software packages. Amazon EC2 allows you to select a configuration of memory, CPU, instance storage, and the boot partition size that is optimal for your choice of operating system and application.

  On the other hand, Amazon WorkSpaces provides the following key features:

  • Support Multiple Devices- Users can access their Amazon WorkSpaces using their choice of device, such as a laptop computer (Mac OS or Windows), iPad, Kindle Fire, or Android tablet.
  • Keep Your Data Secure and Available- Amazon WorkSpaces provides each user with access to persistent storage in the AWS cloud. When users access their desktops using Amazon WorkSpaces, you control whether your corporate data is stored on multiple client devices, helping you keep your data secure.
  • Choose the Hardware and Software you need- Amazon WorkSpaces offers a choice of bundles providing different amounts of CPU, memory, and storage so you can match your Amazon WorkSpaces to your requirements. Amazon WorkSpaces offers preinstalled applications (including Microsoft Office) or you can bring your own licensed software.

Amazon EBS vs Amazon EFS

An Amazon EBS volume stores data in a single Availability Zone.
To attach an Amazon EC2 instance to an EBS volume, both the Amazon EC2 instance and the EBS volume must reside within the same Availability Zone.

Amazon EFS is a regional service. It stores data in and across multiple Availability Zones.
The duplicate storage enables you to access data concurrently from all the Availability Zones in the Region where a file system is located. Additionally, on-premises servers can access Amazon EFS using AWS Direct Connect.

(Source: r/AWSCertifications)

Study Materials and Timeline:

I watched (binged) the A Cloud Guru course in two days and did the 6 practice exams over a week. I originally was only getting 70%’s on the exams, but continued doing them on my free time (to the point where I’d have 15 minutes and knock one out on my phone lol) and started getting 90%’s. – A mix of knowledge vs memorization tbh. Just make sure you read why your answers are wrong.

I don’t really have a huge IT background, although will note I work in a DevOps (1 1/2 years) environment; so I do use AWS to host our infrastructure. However, the exam is very high level compared to what I do/services I use. I’m fairly certain with zero knowledge/experience, someone could pass this within two weeks. AWS is also currently promoting a “get certified” challenge and is offering 50% off.

Best!

Good Tool For AWS Certified Cloud Practitioner Exam Preparation

PASSED AWS CCP (2022)

Went through the entire CloudAcademy course. Most of the info went out the other ear. Got a 67% on their final exam. Took the ExamPro free exam, got 69%.

Was going to take it last Saturday, but I bought TutorialDojo’s exams on Udemy. Did one Friday night, got a 50% and rescheduled it a week later to today Sunday.

Took 4 total TD exams. Got a 50%, 54%, 67%, and 64%. Even up until last night I hated the TD exams with a passion, I thought they were covering way too much stuff that didn’t even pop up in study guides I read. Their wording for some problems were also atrocious. But looking back, the bulk of my “studying” was going through their pretty well written explanations, and their links to the white papers allowed me to know what and where to read.

Not sure what score I got yet on the exam. As someone who always hated testing, I’m pretty proud of myself. I also had to take a dump really bad starting at around question 25. Thanks to TutorialsDojo Jon Bonso for completely destroying my confidence before the exam, forcing me to up my game. It’s better to walk in way over prepared than underprepared.

Just Passed My CCP exam today (within 2 weeks)

I would like to thank this community for recommendations about exam preparation. It was wayyyy easier than I expected (also way easier than TD practice exams scenario-based questions-a lot less wordy on real exam). I felt so unready before the exam that I rescheduled the exam twice. Quick tip: if you have limited time to prepare for this exam, I would recommend scheduling the exam beforehand so that you don’t procrastinate fully.

Resources:

-Stephane’s course on Udemy (I have seen people saying to skip hands-on videos but I found them extremely helpful to understand most of the concepts-so try to not skip those hands-on)

-Tutorials Dojo practice exams (I did only 3.5 practice tests out of 5 and already got 8-10 EXACTLY worded questions on my real exam)

Previous Aws knowledge:

-Very little to no experience (deployed my group’s app to cloud via Elastic beanstalk in college-had 0 clue at the time about what I was doing-had clear guidelines)

Preparation duration: -2 weeks (honestly watched videos for 12 days and then went over summary and practice tests on the last two days)

I passed the AWS Certified Cloud Practitioner

 

AWS Certified Cloud Practitioner

I used Stephane Maarek on Udemy. Purchased his course and the 6 Practice Exams. Also got Neal Davis’ 500 practice questions on Udemy. I took Stephane’s class over 2 days, then spent the next 2 weeks going over the tests (3~4 per day) till I was constantly getting over 80% – passed my exam with a 882.

Passed – CCP CLF-C01

 

 

AWS Certified Cloud Practitioner

What an adventure, I’ve never really gieven though to getting a cert until one day it just dawned on me that it’s one of the few resources that are globally accepted. So you can approach any company and basically prove you know what’s up on AWS 😀

Passed with two weeks of prep (after work and weekends)

Resources Used:

• https://www.exampro.co/

  • This was just a nice structured presentation that also gives you the powerpoint slides plus cheatsheets and a nice overview of what is said in each video lecture.

• Udemy – AWS Certified Cloud Practitioner Practice Exams, created by Jon Bonso**, Tutorials Dojo**

  • These are some good prep exams, they ask the questions in a way that actually make you think about the related AWS Service. With only a few “Bullshit! That was asked in a confusing way” questions that popped up.

Pass AWS CCP. The score is beyond expected

I took CCP 2 days ago and got the pass notification right after submitting the answers. In about the next 3 hours I got an email from Credly for the badge. This morning I got an official email from AWS congratulating me on passing, the score is much higher than I expected. I took Stephane Maarek’s CCP course and his 6 demo exams, then Neal Davis’ 500 questions also. On all the demo exams, I took 1 fail and all passes with about 700-800. But in the real exam, I got 860. The questions in the real exam are kind of less verbose IMO, but I don’t truly agree with some people I see on this sub saying that they are easier.
Just a little bit of sharing, now I’ll find something to continue ^^

Good luck with your own exams.

Passed the AWS Certified Cloud Practitioner (CLF-C01) Exam!

Passed the exam! Spent 25 minutes answering all the questions. Another 10 to review. I might come back and update this post with my actual score.

Background

– A year of experience working with AWS (e.g., EC2, Elastic Beanstalk, Route 53, and Amplify).

– Cloud development on AWS is not my strong suit. I just Google everything, so my knowledge is very spotty. Less so now since I studied for this exam.

Study stats

– Spent three weeks studying for the exam.

– Studied an hour to two every day.

– Solved 800-1000 practice questions.

– Took 450 screenshots of practice questions and technology/service descriptions as reference notes to quickly swift through on my phone and computer for review. Screenshots were of questions that I either didn’t know, knew but was iffy on, or those I believed I’d easily forget.

– Made 15-20 pages of notes. Chill. Nothing crazy. This is on A4 paper. Free-form note taking. With big diagrams. Around 60-80 words per page.

– I was getting low-to-mid 70%s on Neal Davis’s and Stephane Maarek’s practice exams. Highest score I got was an 80%.

– I got a 67(?)% on one of Stephane Maarek’s exams. The only sub-70% I ever got on any practice test. I got slightly anxious. But given how much harder Maarek’s exams are compared to the actual exam, the anxiety was undue.

– Finishing the practice exams on time was never a problem for me. I would finish all of them comfortably within 35 minutes.

Resources used

– AWS Cloud Practitioner Essentials on the AWS Training and Certification Portal

– AWS Certified Cloud Practitioner Practice Tests (Book) by Neal Davis

– 6 Practice Exams | AWS Certified Cloud Practitioner CLF-C01 by Stephane Maarek*

– Certified Cloud Practitioner Course by Exam Pro (Paid Version)**

– One or two free practice exams found by a quick Google search

*Regarding Exam Pro: I went through about 40% of the video lectures. I went through all the videos in the first few sections but felt that watching the lectures was too slow and laborious even at 1.5-2x speed. (The creator, for the most part, reads off of the slides, adding brief comments here and there.) So, I decided to only watch the video lectures for sections I didn’t have a good grasp on. (I believe the video lectures provided in the course are just split versions of the full length course available for free on YouTube under the freeCodeCamp channel, here.) The online course provides five practice exams. I did not take any of them.

**Regarding Stephane Maarek: I only took his practice exams. I did not take his study guide course.

Notes

– My study regimen (i.e., an hour to two every day for three weeks) was overkill.

– The questions on the practice exams created by Neal Davis and Stephane Maarek were significantly harder than those on the actual exam. I believe I could’ve passed without touching any of these resources.

– I retook one or two practice exams out of the 10+ I’ve taken. I don’t think there’s a need to retake the exams as long as you are diligent about studying the questions and underlying concepts you got wrong. I reviewed all the questions I missed on every practice exam the day before.

What would I do differently?

– Focus on practice tests only. No video lectures.

– Focus on the technologies domain. You can intuit your way through questions in the other domains.

– Chill

Passed CLF-CO1!!

I thank you all for helping me through this process! Couldn’t have done it without all of the recommendations and guidance on this page.

Background: I am a back-end developer that works 12 hours a day for corporate America, so no time to study (or do anything) but I made it work.

Could I have probably gone for SAA first? Yeah, but I wanted to prove to myself that I could do it. I studied for about a month. I used Maarek’s Udemy course at 1.5x speed and I couldn’t recommend it more. I also used his practice exams. I’ll be honest, I took 5 practice exams and got somehow managed to fail every single one in the mid 60’s lol. Cleared the exam with an 800. Practice exams WAY harder.

My 2 cents on must knows:

• AWS Shared Security Model (who owns what)

• Everything Billing (EC2 instance, S3, different support plans)

• I had a few ML questions that caught me off guard

• VPC concepts – i.e. subnets, NACL, Transit Gateway

I passed the AWS CCP today 

I studied solidly for two weeks, starting with Tutorials Dojo (which was recommended somewhere on here). I turned all of their vocabulary words and end of module questions into note cards. I did the same with their final assessment and one free exam.

During my second week, I studied the cards for anywhere from one to two hours a day, and I’d randomly watch videos on common exam questions.

The last thing I did was watch a 3 hr long video this morning that walks you through setting up AWS Instances. The visual of setting things up filled in a lot of holes.

I had some PSI software problems, and ended up getting started late. I was pretty dejected towards the end of the exam, and was honestly (and pleasantly) surprised to see that I passed.

Hopefully this helps someone. Keep studying and pushing through – if you know it, you know it. Even if you have a bad start. Cheers 🍻

  by /u/Substantial-Peach382 (AWS Certifications) on February 7, 2023 at 1:11 am

  Been studying for SAA since October. Did Stephane’s course and have studied constantly between 10-20 hours every week. Flashcards, many rewatches, building my own architectures + hands on. I feel very confident with nearly all the services, score >85% on all the Stephane/TD practice exams. Definitely feel like I can get caught off guard but some small details of services like (ex. EKS, Config, IAM Identity center, cognito identity pools) but for the most part, even with the services I am not the best at, I definitely know what they do and some use cases for using them.

• How to leverage these certs

  Hey everyone, I’ve been creeping around on this sub reading various things for a while. I’m a CS student who will graduate next year. I’m interested in working in cloud security (AWS). I realize that cloud devops etc are not entry fields and that getting these certs + projects will only give me a low chance of getting an entry level job. My plan is to stick to full stack/back end and then try to first get CCP and SAA with some projects to try to transition to a role that I want. What is an ideal way to leverage getting these certs and understanding the material to get a career in cloud. If you can give me some example scenarios I’d appreciate it Thanks in advance submitted by /u/Makhann007 [link] [comments]

• AWS Systems Manager Change Manager now supports a more flexible way of approving change requests
  by aws@amazon.com (Recent Announcements) on February 6, 2023 at 6:03 pm

  Change Manager, a capability of AWS Systems Manager, helps customers request, approve, implement, and report on operational changes to their application configuration and infrastructure on AWS and on premises. With this launch, customers can now set a required number of approvers for a change request before adding all eligible approvers. This provides requesters with additional flexibility to add multiple approvers for the request and get the change approved as soon as the required number is achieved. For example, customers can require three approvals for a level but specify up to five approvers. Approvals from any three of those approvers are sufficient to approve the level.

To help you get a comprehensive view of operational changes, Change Calendar integrates with other Systems Manager capabilities, such as Automation, Maintenance Windows, State Manager, and Change Manager, and pre-populates your Change Calendar with the operational events view. This new feature automatically displays operational events alongside your business-critical events to help customers become aware of restricted periods while scheduling new tasks.

  by /u/GloomyMelons (AWS Certifications) on February 6, 2023 at 2:05 pm

  Hey so I'm trying to familiarize myself with AWS. I don't use it in my job but still wanna familiarize myself with the platform. My employer pays for cbtnuggets so I started using the CLF-C01 course on cbtnuggets, but the course is out of date and doesn't work anymore. For example, Amazon has changed the gui since the course was made in 2019 and stuff like creating cloud trail logs is different. I tried following the course on cbtnuggets but it's difficult when everything is different now than it was in the video. I inadvertently ended up charging 52 cents from the service for nothing but cloud trail logs in s3 buckets because of how bad the course is now so I'm looking for a course that is relevant. Any recs?

The course was great, and the exam questions came exactly like the practice tests surprisingly. Preparing for the exam was not difficult as I have many experience in software development. I'm writing this post for all instructors to include cloud9 in their course since it was not covered in Neal Davis course, the cheat sheets or the practice tests. Link: https://aws.amazon.com/cloud9/ The question was: What is a cloud-based integrated development environment (IDE) that lets you write, run, and debug your code with just a browser?

  by /u/cohenwebdesigndotcom (AWS Certifications) on February 5, 2023 at 4:56 pm

  Preparation Time: 3 Days -- About 10 Hours Total Resources: I used four resources, that's it. FreeCodeCamp AWS CCP Training (4 Hour Version from 2020) (FREE) https://www.youtube.com/watch?v=3hLmDS179YE Free Practice Quizzes from AWS training website (FREE) https://aws.amazon.com/certification/certified-cloud-practitioner/ Quizlet Practice Exams from several people (FREE, signed up for Quizlet+ trial for unlimited Learning function) Tutorial Dojo Practice Exams by Jon Bonso. Purchased directly from the website ($15). My background: Senior student in Computer Science. No direct experience with AWS, but worked alongside peers who used AWS. Knew basic concepts, like Lambda functions being serverless and that cloud computing is pay-as-you-go. Nothing too serious. My opinions: Tutorial Dojo practice tests are top-tier. The real exam is NOT a "cake walk." A lot of the questions for me (I marked 13) were narrowed down between two possible answers. The test was not super hard or time consuming, but it is not like a permit test IMO. If you have a background in IT, you do not need more than a week to study. If not, practice until you get ~70-80 percent on Tutorial Dojo tests. ​ *EDIT* Just got my official score, 827/1000 (where 700 is minimum passing). So not a narrow pass, but not as impressive as others who have prepped longer. submitted by /u/cohenwebdesigndotcom [link] [comments]

• Why do I have to sign in over and over?
  by /u/mikedpayne (AWS Certifications) on February 5, 2023 at 3:49 pm

  The entire time I've been using AWS Skillbuilder it is constantly making me sign back in and confirming that I want to use my Amazon account. Now that I'm trying to do the Cloud Quests, I often can't get through a video without the performance degrading horribly and me having to reload it, at which point I have to sign in again. Am I doing something wrong? What is this madness? submitted by /u/mikedpayne [link] [comments]

• Is there a way to determine the cost for a specific container on ECS?

• A “Duh” Tip
  by /u/aahkellyclarkson (AWS Certifications) on February 4, 2023 at 5:21 pm

  I keep doing this, so I thought I’d share a tip with you all. I keep zeroing in on an answer and then it turns out it was partially correct or it didn’t address every single facet of the question. So a tip I have is to read your question, find your answer, and then SCRUB THE ANSWER BACK AGAINST THE QUESTION. As in: ok, this is my answer. Let me take the question sentence by sentence and make sure this fits every single thing they are asking for. Idk if y’all are all doing this and this is useless advice but this is consistently helping me test better so I thought I’d share in case someone else is missing this crucial step. submitted by /u/aahkellyclarkson [link] [comments]

• SAA-03 - Do questions like this, talking about Wavelength Zones and properties like 'AmazonEKSFargatePodExecutionRole' really show up on exam? This is TD practice exam, but I took Maarek course and this level of detail never showed up for EKS/Containers.
