PHOnA aggregates HpTFs from different laboratories, including measurements for multiple different headphones, subjects, and repositionings of headphones for each subject. The dataset uses the spatially oriented format for acoustics (SOFA), and SOFA conventions are proposed for efficiently storing HpTFs. PHOnA is intended to provide a foundation for machine learning techniques applied to HpTF equalization. This shared data will allow optimization of equalization algorithms to provide more universal solutions to perceptually transparent headphone reproduction. Access it here.

Natural History Museum in London

The Natural History Museum in London has 80 million items (and counting!) in its collections, from the tiniest specks of stardust to the largest animal that ever lived – the blue whale. 

The Digital Collections Programme is a project to digitise these specimens and give the global scientific community access to unrivalled historical, geographic and taxonomic specimen data gathered in the last 250 years. Mobilising this data can facilitate research into some of the most pressing scientific and societal challenges.

Digitising involves creating a digital record of a specimen which can consist of all types of information such as images, and geographical and historical information about where and when a specimen was collected. The possibilities for digitisation are quite literally limitless – as technology evolves, so do possible uses and analyses of the collections. We are currently exploring how machine learning and automation can help us capture information from specimen images and their labels.

With such a wide variety of specimens, digitising looks different for every single collection. How we digitise a fly specimen on a microscope slide is very different to how we might digitise a bat in a spirit jar! We develop new workflows in response to the type of specimens we are dealing with. Sometimes we have to get really creative, and have even published on workflows which have involved using pieces of LEGO to hold specimens in place while we are imaging them.

Mobilising this data and making it open access is at the heart of the project. All of the specimen data is released on our Data Portal, and we also feed the data into international databases such as GBIF.

Electric Cars – Autonomous Cars – Self driving cars : Tesla, CyberTruck, EV, Volt, Wayne, Nissan Leaf, Electric Bikes, e-bikes, i-cars, smart cars


This blog explores Clever Questions and Answers about Electric Vehicles, Autonomous Cars, Self driving cars, Tesla, Volt, Wayne, Nissan Leaf, Electric Bikes, e-bikes, i-cars, smart cars, Cyber Trucks, etc…

BNEF outlines that electric vehicles (EVs) will hit 10% of global passenger vehicle sales in 2025, with that number rising to 28% in 2030 and 58% in 2040. According to the study, EVs currently make up 3% of global car sales.

The 5 Levels of Autonomous Vehicles

  • Level 0 – No Automation. This describes your everyday car.
  • Level 1 – Driver Assistance. Here we can find your adaptive cruise control and lane keep assist to help with driving fatigue.
  • Level 2 – Partial Automation.
  • Level 3 – Conditional Automation.
  • Level 4 – High Automation.
  • Level 5 – Full Automation.


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.


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.

Pros and Cons of CyberTruck


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.

CONS: Cybertruck hurdles. What are the design and production issues that engineers still have to over come?

  1. Crash tests/crumple zone.
  2. Side Mirrors?
  3. Regulatory approval
  4. Stainless steel in salty environments.
  5. Tire size/ range efficiency? Looks cool but….

I realize the shape is actually very efficient to build, ridged and aerodynamic. Looking for feedback.

As a Tesla owner, do you agree that it’s the best car you’ve ever purchased?

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 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.


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.


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.


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’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.


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.


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’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.


1- Does using cruise control when going downhill in an electric car use more energy?

No – quite the opposite in fact.

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):

2- How was your Tesla car buying experience? Which Tesla; Model X, Model S, Model 3, or Model Y?

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.


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.

3- What are some unforeseen impacts of self-driving cars?


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:

You don’t need a Google Account to participate in Meet video meetings. However, if you don’t have a Google Account, the meeting organizer or someone from the organization must grant you access to the meeting. Tip: If you are not signed into a Google or Gmail accountyou cannot join using your mobile device.
Microsoft Teams is excellent for internal collaboration, whereas Zoom is often preferred for working externally – whether that’s with customers or guest vendors.
Security – Encryption ZOOM
Zoom claims that meetings are secure with end to end encryption, but it does not use the end-to-end encryption.
The Security icon in the meeting controls allows the host or co-host of a meeting to enable or disable options during a meeting to secure the meeting and minimize disruption during the meeting. Most of the settings can be controlled from Account, Group, and User settings prior to the meeting
All data in Google Meet is encrypted in transit by default between the client and Google for video meetings on a web browser, on the Meet Android and Apple® iOS® apps, and in meeting rooms with Google meeting room hardware. Meet recordings stored in Google Drive are encrypted at rest by default.
Google Meet has an anti-abuse feature that keeps the meetings safe with its anti-hijacking features and allowing the host to secure all controls of the meeting. This feature also allows multiple 2-step verification processes and security keys.
Teams enforces team-wide and organization-wide two-factor authentication, single sign-on through Active Directory, and encryption of data in transit and at rest. Files are stored in SharePoint and are backed by SharePoint encryption. Notes are stored in OneNote and are backed by OneNote encryption.

Extra Unique Features ZOOM
Zoom has all the basic features such as screen sharing, file sharing, and a message box. But the distinguishing feature of Zoom is it allows you to control all settings, from enabling waiting rooms, allowing participants to rename themselves and give reactions, controlling the chatbox options, and much, much more.
Google Meet allows live captioning during meetings with its automated live captions powered by Google Speech. It also allows you to check video and audio controls before you enter a meeting.
The Google Meet layout automatically adjusts to display the most active content and participants. It also has screen sharing features, chat features, file sharing features, and is integrated with Microsoft and Google Apps.
Additional features that Microsoft Teams has, are the customizable backgrounds, the ‘together mode’ in which all members sit together in the same background making it feel like they are all at one place, and file sharing and co-authoring files in real-time.

Google Meet is a far stronger and more intuitive product than the video calling feature on Microsoft Teams and Zoom.
Device compatibilities ZOOM
Zoom is compatible with all devices whether it is a desktop/laptop, Android, iPhone, or iPad.
Google Meet is compatible across many devices whether it is a desktop/laptop, Android, iPhone, or iPad.
Microsoft Teams is compatible with iOS, Android, macOS, and Windows and is mostly free for up to 300 people and 5GB worth of files.
We have had great success and increase moblity by using this product. Extremely intuitive so video conference meetings are now becoming more popular than the face-to-face.

Which do you prefer for video calls: Skype, Zoom, or Google Hangouts?

I prefer Zoom and I have used all three of these mediums.

I prefer Zoom because its streamlined and easy for domestic and international clients. I like Zoom because you can utilize breakout rooms to easily divide people in to groups for short periods of time and have people raise their hand so you can toggle over audio during a busy call with a lot of people on. It’s great for managing webinars as well as internal team meets or client correspondences.

Is it possible to transcribe a meeting on Google Meet? If yes, how?

Yes, it’s possible. All you need is to create a free account at SpeechText AI audio transcription service and upload recorded audio files.

Here is the step-by-step guide:

1. In Google Meet, start recording the meeting. Click “More” (3 vertical dots on the lower right-hand side) and choose the “Record Meeting” option.

2. Recorded Google Meet video will be automatically stored in your Google Drive. Check “My Drive” -> “Meet recordings” folder. An email with a link to the Google Meet recording will also be sent to the meeting administrator. You need to download it to your computer.

3. Create a trial SpeechText AI account. It’s free.

4. Locate your downloaded recording on your computer and upload it to the cloud transcription service.

5. SpeechText AI is the first multilingual and industry-specific audio transcription engine. To start transcription you should accurately select the transcription language (the service supports more than 30 languages and accents), industry to accurately transcribe domain-specific terms and audio type (in your case it will be the ‘Meeting record’).

6. Hit the “Transcribe” button and SpeechText AI transcribes your Google Meet meeting in seconds.

I’ve attached the example of transcription results you can get using SpeechText AI service. It’s the interview of Elon Musk at The Late Show with Stephen Colbert.

Is Google Classroom safer than Zoom?

The Cloud is the future: The AWS Certified Solutions Architect – Associate Averge salary is $149,446/year. Get Certified Now with the apps below:

Google Classroom and Zoom are completely different types of programs. Classroom is used for assigning and tracking student work while Zoom is a platform for video conferencing. Google does have an equivalent to Zoom in their Google Meets app, but Zoom does not have an equivalent to Google Classroom.

As teachers at my school had already started is Zoom back when lockdown started, it was easier to continue using the same format than to transition to a different platform, plus there was a *ridiculously* long wait to get approval for Google Classroom back when every school in the country was scrambling to become a provider of online education all at the same time.

From the reports I’ve heard, both Google Meets and Zoom had security issues when they got all of those new customers all at once. Both have increased security over the past few months & added extra layers of security to the point that security issues seem to be pretty far in between, or at least you hear fewer reports of them. Now it seems to be more an issue of them both working on improving system stability, so there are fewer system-wide crashes & fewer dropped participants.

How do I record a full screen view in Google Meet when someone else is in the sharing screen?

You can use a third-party screen recorder to meet that goal. The tool I widely used to capture meeting calls on PC is RecMaster. It comes with multiple recording modes and simultaneously provides versatile recording tools. Here let me show you how to record Google Meet in Full screen.

Step 1: Download and make RecMaster running on your computer. After that, choose the Full screen mode to capture the Google Meet call.

Step 2: Choose the system sound button so that the speaker’s voice will be recorded. Here you can also make configuration on the video format, video quality, frame rate one by one. If you are holding any fixed-time recording, you can preset the beginning and ending time of the recording and it will automatically start.

Step 3: Press REC button to start. When it’s time to end this task, tab the red button again to terminate the recording.

Now you’ve got the desired video. You can upload it to Google Drive, YouTube or share with ease.

How do you improve your online class experience on a Zoom cloud meeting?

Here are some additional online resources to help you most effectively use Zoom for virtual education:

  • Live Zoom training dailyThese include sessions specifically highlighting Zoom Meetings for Education (Students & Educators), focusing on using Zoom Meetings as your classroom setting. Zoom Webinar training is also available.

The Google Certified Cloud Professional Architect covers the following topics:

Designing and planning a cloud solution architecture: 36%

This domain tests your ability to design a solution infrastructure that meets business and technical requirements and considers network, storage and compute resources. It will test your ability to create a migration plan, and that you can envision future solution improvements.

Managing and provisioning a solution Infrastructure: 20%

This domain will test your ability to configure network topologies, individual storage systems and design solutions using Google Cloud networking, storage and compute services.

Designing for security and compliance: 12%

This domain assesses your ability to design for security and compliance by considering IAM policies, separation of duties, encryption of data and that you can design your solutions while considering any compliance requirements such as those for healthcare and financial information.

Managing implementation: 10%

This domain tests your ability to advise development/operation team(s) to make sure you have successful deployment of your solution. It also tests yours ability to interact with Google Cloud using GCP SDK (gcloud, gsutil, and bq).

Ensuring solution and operations reliability: 6%

This domain tests your ability to run your solutions reliably in Google Cloud by building monitoring and logging solutions, quality control measures and by creating release management processes.

Analyzing and optimizing technical and business processes: 16%

This domain will test how you analyze and define technical processes, business processes and develop procedures to ensure resilience of your solutions in production.

Below are the Top 50 Google Certified Cloud Professional Architect Exam Questions and Answers Dumps: You will need to have the three case studies referred to in the exam open in separate tabs in order to complete the exam: Company A , Company B, Company C

Question 1:  Because you do not know every possible future use for the data Company A collects, you have decided to build a system that captures and stores all raw data in case you need it later. How can you most cost-effectively accomplish this goal?

 A. Have the vehicles in the field stream the data directly into BigQuery.

B. Have the vehicles in the field pass the data to Cloud Pub/Sub and dump it into a Cloud Dataproc cluster that stores data in Apache Hadoop Distributed File System (HDFS) on persistent disks.

C. Have the vehicles in the field continue to dump data via FTP, adjust the existing Linux machines, and use a collector to upload them into Cloud Dataproc HDFS for storage.

D. Have the vehicles in the field continue to dump data via FTP, and adjust the existing Linux machines to immediately upload it to Cloud Storage with gsutil.




D is correct because several load-balanced Compute Engine VMs would suffice to ingest 9 TB per day, and Cloud Storage is the cheapest per-byte storage offered by Google. Depending on the format, the data could be available via BigQuery immediately, or shortly after running through an ETL job. Thus, this solution meets business and technical requirements while optimizing for cost.

Reference: Streaming insertsApache Hadoop and Spark10 tips for building long running cluster using cloud dataproc

Question 2: Today, Company A maintenance workers receive interactive performance graphs for the last 24 hours (86,400 events) by plugging their maintenance tablets into the vehicle. The support group wants support technicians to view this data remotely to help troubleshoot problems. You want to minimize the latency of graph loads. How should you provide this functionality?

A. Execute queries against data stored in a Cloud SQL.

B. Execute queries against data indexed by vehicle_id.timestamp in Cloud Bigtable.

C. Execute queries against data stored on daily partitioned BigQuery tables.

D. Execute queries against BigQuery with data stored in Cloud Storage via BigQuery federation.




B is correct because Cloud Bigtable is optimized for time-series data. It is cost-efficient, highly available, and low-latency. It scales well. Best of all, it is a managed service that does not require significant operations work to keep running.

Reference: BigTables time series clusterBigQuery

Question 3: Your agricultural division is experimenting with fully autonomous vehicles. You want your architecture to promote strong security during vehicle operation. Which two architecture characteristics should you consider?

A. Use multiple connectivity subsystems for redundancy. 

B. Require IPv6 for connectivity to ensure a secure address space. 

C. Enclose the vehicle’s drive electronics in a Faraday cage to isolate chips.

D. Use a functional programming language to isolate code execution cycles.

E. Treat every microservice call between modules on the vehicle as untrusted.

F. Use a Trusted Platform Module (TPM) and verify firmware and binaries on boot.


E and F


E is correct because this improves system security by making it more resistant to hacking, especially through man-in-the-middle attacks between modules.

F is correct because this improves system security by making it more resistant to hacking, especially rootkits or other kinds of corruption by malicious actors.

Reference 3: Trusted Platform Module

Question 4: For this question, refer to the Company A case study.

Which of Company A’s legacy enterprise processes will experience significant change as a result of increased Google Cloud Platform adoption?

A. OpEx/CapEx allocation, LAN change management, capacity planning

B. Capacity planning, TCO calculations, OpEx/CapEx allocation 

C. Capacity planning, utilization measurement, data center expansion

D. Data center expansion, TCO calculations, utilization measurement




B is correct because all of these tasks are big changes when moving to the cloud. Capacity planning for cloud is different than for on-premises data centers; TCO calculations are adjusted because Company A is using services, not leasing/buying servers; OpEx/CapEx allocation is adjusted as services are consumed vs. using capital expenditures.

Reference: Cloud Economics

Question 5: For this question, refer to the Company A case study.

You analyzed Company A’s business requirement to reduce downtime and found that they can achieve a majority of time saving by reducing customers’ wait time for parts. You decided to focus on reduction of the 3 weeks’ aggregate reporting time. Which modifications to the company’s processes should you recommend?

A. Migrate from CSV to binary format, migrate from FTP to SFTP transport, and develop machine learning analysis of metrics.

B. Migrate from FTP to streaming transport, migrate from CSV to binary format, and develop machine learning analysis of metrics.

C. Increase fleet cellular connectivity to 80%, migrate from FTP to streaming transport, and develop machine learning analysis of metrics.

D. Migrate from FTP to SFTP transport, develop machine learning analysis of metrics, and increase dealer local inventory by a fixed factor.




C is correct because using cellular connectivity will greatly improve the freshness of data used for analysis from where it is now, collected when the machines are in for maintenance. Streaming transport instead of periodic FTP will tighten the feedback loop even more. Machine learning is ideal for predictive maintenance workloads.

Question 6: Your company wants to deploy several microservices to help their system handle elastic loads. Each microservice uses a different version of software libraries. You want to enable their developers to keep their development environment in sync with the various production services. Which technology should you choose?


B. Containers 

C. Chef/Puppet

D. Virtual machines




B is correct because using containers for development, test, and production deployments abstracts away system OS environments, so that a single host OS image can be used for all environments. Changes that are made during development are captured using a copy-on-write filesystem, and teams can easily publish new versions of the microservices in a repository.

Question 7: Your company wants to track whether someone is present in a meeting room reserved for a scheduled meeting. There are 1000 meeting rooms across 5 offices on 3 continents. Each room is equipped with a motion sensor that reports its status every second. You want to support the data upload and collection needs of this sensor network. The receiving infrastructure needs to account for the possibility that the devices may have inconsistent connectivity. Which solution should you design?

A. Have each device create a persistent connection to a Compute Engine instance and write messages to a custom application.

B. Have devices poll for connectivity to Cloud SQL and insert the latest messages on a regular interval to a device specific table. 

C. Have devices poll for connectivity to Cloud Pub/Sub and publish the latest messages on a regular interval to a shared topic for all devices.

D. Have devices create a persistent connection to an App Engine application fronted by Cloud Endpoints, which ingest messages and write them to Cloud Datastore.




C is correct because Cloud Pub/Sub can handle the frequency of this data, and consumers of the data can pull from the shared topic for further processing.

Question 8: Your company wants to try out the cloud with low risk. They want to archive approximately 100 TB of their log data to the cloud and test the analytics features available to them there, while also retaining that data as a long-term disaster recovery backup. Which two steps should they take?

A. Load logs into BigQuery. 

B. Load logs into Cloud SQL.

C. Import logs into Stackdriver. 

D. Insert logs into Cloud Bigtable.

E. Upload log files into Cloud Storage.


A and E


A is correct because BigQuery is the fully managed cloud data warehouse for analytics and supports the analytics requirement.

E is correct because Cloud Storage provides the Coldline storage class to support long-term storage with infrequent access, which would support the long-term disaster recovery backup requirement.

References: BigQueryStackDriverBigTableStorage Class: ColdLine

Question 9: You set up an autoscaling instance group to serve web traffic for an upcoming launch. After configuring the instance group as a backend service to an HTTP(S) load balancer, you notice that virtual machine (VM) instances are being terminated and re-launched every minute. The instances do not have a public IP address. You have verified that the appropriate web response is coming from each instance using the curl command. You want to ensure that the backend is configured correctly. What should you do?

A. Ensure that a firewall rule exists to allow source traffic on HTTP/HTTPS to reach the load balancer. 

B. Assign a public IP to each instance, and configure a firewall rule to allow the load balancer to reach the instance public IP.

C. Ensure that a firewall rule exists to allow load balancer health checks to reach the instances in the instance group.

D. Create a tag on each instance with the name of the load balancer. Configure a firewall rule with the name of the load balancer as the source and the instance tag as the destination.




C is correct because health check failures lead to a VM being marked unhealthy and can result in termination if the health check continues to fail. Because you have already verified that the instances are functioning properly, the next step would be to determine why the health check is continuously failing.

Reference: Load balancingLoad Balancing Health Checking

Question 10: Your organization has a 3-tier web application deployed in the same network on Google Cloud Platform. Each tier (web, API, and database) scales independently of the others. Network traffic should flow through the web to the API tier, and then on to the database tier. Traffic should not flow between the web and the database tier. How should you configure the network?

A. Add each tier to a different subnetwork.

B. Set up software-based firewalls on individual VMs. 

C. Add tags to each tier and set up routes to allow the desired traffic flow.

D. Add tags to each tier and set up firewall rules to allow the desired traffic flow.




D is correct because as instances scale, they will all have the same tag to identify the tier. These tags can then be leveraged in firewall rules to allow and restrict traffic as required, because tags can be used for both the target and source.

Reference: Using VPCRoutesAdd Remove Network

Question 11: Your organization has 5 TB of private data on premises. You need to migrate the data to Cloud Storage. You want to maximize the data transfer speed. How should you migrate the data?

A. Use gsutil.

B. Use gcloud.


D. Use Storage Transfer Service.




A is correct because gsutil gives you access to write data to Cloud Storage.

Reference: gsutilsgcloud sdkcloud storage json apiuploading objectsstorage transfer

Question 12: You are designing a mobile chat application. You want to ensure that people cannot spoof chat messages by proving that a message was sent by a specific user. What should you do?

A. Encrypt the message client-side using block-based encryption with a shared key.

B. Tag messages client-side with the originating user identifier and the destination user.

C. Use a trusted certificate authority to enable SSL connectivity between the client application and the server. 

D. Use public key infrastructure (PKI) to encrypt the message client-side using the originating user’s private key.




D is correct because PKI requires that both the server and the client have signed certificates, validating both the client and the server.

Question 13: You are designing a large distributed application with 30 microservices. Each of your distributed microservices needs to connect to a database backend. You want to store the credentials securely. Where should you store the credentials?

A. In the source code

B. In an environment variable 

C. In a key management system

D. In a config file that has restricted access through ACLs




Question 14: For this question, refer to the Company B case study.

Company B wants to set up a real-time analytics platform for their new game. The new platform must meet their technical requirements. Which combination of Google technologies will meet all of their requirements?

A. Kubernetes Engine, Cloud Pub/Sub, and Cloud SQL

B. Cloud Dataflow, Cloud Storage, Cloud Pub/Sub, and BigQuery 

C. Cloud SQL, Cloud Storage, Cloud Pub/Sub, and Cloud Dataflow

D. Cloud Pub/Sub, Compute Engine, Cloud Storage, and Cloud Dataproc




B is correct because:
Cloud Dataflow dynamically scales up or down, can process data in real time, and is ideal for processing data that arrives late using Beam windows and triggers.
Cloud Storage can be the landing space for files that are regularly uploaded by users’ mobile devices.
Cloud Pub/Sub can ingest the streaming data from the mobile users.
BigQuery can query more than 10 TB of historical data.

Question 15: For this question, refer to the Company B case study.

Company B has deployed their new backend on Google Cloud Platform (GCP). You want to create a thorough testing process for new versions of the backend before they are released to the public. You want the testing environment to scale in an economical way. How should you design the process?A. Create a scalable environment in GCP for simulating production load.B. Use the existing infrastructure to test the GCP-based backend at scale. C. Build stress tests into each component of your application and use resources from the already deployed production backend to simulate load.D. Create a set of static environments in GCP to test different levels of load—for example, high, medium, and low.




A is correct because simulating production load in GCP can scale in an economical way.

Question 16: For this question, refer to the Company B case study.

Company B wants to set up a continuous delivery pipeline. Their architecture includes many small services that they want to be able to update and roll back quickly. Company B has the following requirements:

  • Services are deployed redundantly across multiple regions in the US and Europe
  • Only frontend services are exposed on the public internet.
  • They can reserve a single frontend IP for their fleet of services.
  • Deployment artifacts are immutable

Which set of products should they use?

A. Cloud Storage, Cloud Dataflow, Compute Engine

B. Cloud Storage, App Engine, Cloud Load Balancing

C. Container Registry, Google Kubernetes Engine, Cloud Load Balancing

D. Cloud Functions, Cloud Pub/Sub, Cloud Deployment Manager




C is correct because:
Google Kubernetes Engine is ideal for deploying small services that can be updated and rolled back quickly. It is a best practice to manage services using immutable containers.
Cloud Load Balancing supports globally distributed services across multiple regions. It provides a single global IP address that can be used in DNS records. Using URL Maps, the requests can be routed to only the services that Company B wants to expose.
Container Registry is a single place for a team to manage Docker images for the services.

Question 17: Your customer is moving their corporate applications to Google Cloud Platform. The security team wants detailed visibility of all resources in the organization. You use Resource Manager to set yourself up as the org admin. What Cloud Identity and Access Management (Cloud IAM) roles should you give to the security team?

A. Org viewer, Project owner

B. Org viewer, Project viewer 

C. Org admin, Project browser

D. Project owner, Network admin




B is correct because:
Org viewer grants the security team permissions to view the organization's display name.
Project viewer grants the security team permissions to see the resources within projects.

Question 18: To reduce costs, the Director of Engineering has required all developers to move their development infrastructure resources from on-premises virtual machines (VMs) to Google Cloud Platform. These resources go through multiple start/stop events during the day and require state to persist. You have been asked to design the process of running a development environment in Google Cloud while providing cost visibility to the finance department. Which two steps should you take?

A. Use persistent disks to store the state. Start and stop the VM as needed. 

B. Use the –auto-delete flag on all persistent disks before stopping the VM. 

C. Apply VM CPU utilization label and include it in the BigQuery billing export.

D. Use BigQuery billing export and labels to relate cost to groups. 

E. Store all state in local SSD, snapshot the persistent disks, and terminate the VM.F. Store all state in Cloud Storage, snapshot the persistent disks, and terminate the VM.


A and D


A is correct because persistent disks will not be deleted when an instance is stopped.

D is correct because exporting daily usage and cost estimates automatically throughout the day to a BigQuery dataset is a good way of providing visibility to the finance department. Labels can then be used to group the costs based on team or cost center.

Question 19: Your company has decided to make a major revision of their API in order to create better experiences for their developers. They need to keep the old version of the API available and deployable, while allowing new customers and testers to try out the new API. They want to keep the same SSL and DNS records in place to serve both APIs. What should they do?

A. Configure a new load balancer for the new version of the API.

B. Reconfigure old clients to use a new endpoint for the new API. 

C. Have the old API forward traffic to the new API based on the path.

D. Use separate backend services for each API path behind the load balancer.




D is correct because an HTTP(S) load balancer can direct traffic reaching a single IP to different backends based on the incoming URL.

Question 20: The database administration team has asked you to help them improve the performance of their new database server running on Compute Engine. The database is used for importing and normalizing the company’s performance statistics. It is built with MySQL running on Debian Linux. They have an n1-standard-8 virtual machine with 80 GB of SSD zonal persistent disk. What should they change to get better performance from this system in a cost-effective manner?

A. Increase the virtual machine’s memory to 64 GB.

B. Create a new virtual machine running PostgreSQL. 

C. Dynamically resize the SSD persistent disk to 500 GB.

D. Migrate their performance metrics warehouse to BigQuery.




C is correct because persistent disk performance is based on the total persistent disk capacity attached to an instance
