1. TerramEarth is considering building an analytics database and making it available to equipment designers. The designers require the ability to query the data with SQL. The analytics database manager wants to minimize the cost of the service. What would you recommend?

2. Dress4Win has just developed a new feature for its social networking service. Customers can upload images of their clothes, create montages from those images, and share them on social networking sites. Images are temporarily saved to locally attached drives as the customer works on the montage. When the montage is complete, the final version is copied to a Cloud Storage bucket. The services implementing this feature run in a managed instance group. Several users have noted that their final montages are not available even though they saved them in the application. No other problems have been reported with the service. What might be causing this problem?

3. Why would you want to run long-running, compute-intensive backend computation in a different managed instance group than on web servers supporting a minimal user interface?

4. The finance director in your company is frustrated with the poor availability of an on-premises finance data warehouse. The data warehouse uses a commercial relational database that only scales by buying larger and larger servers. The director asks for your advice about moving the data warehouse to the cloud and if the company can continue to use SQL to query the data warehouse. What GCP service would you recommend to replace the on-premises data warehouse?

5. A group of business executives and software engineers are discussing the level of risk that is acceptable for a new application. Business executives want to minimize the risk that the service is not available. Software engineers note that the more developer time dedicated to reducing risk of disruption, the less time they have to implement new features. How can you formalize the group’s tolerance for risk of disruption?

6. A team of architects in your company is defining standards to improve availability. In addition to recommending redundancy and code reviews for configuration changes, what would you recommend to include in the standards?

7. Your development team has implemented a new application using a microservices architecture. You would like to minimize DevOps overhead by deploying the services in a way that will autoscale. You would also like to run each microservice in containers. What is a good option for implementing these requirements in Google Cloud Platform?

8. Your company is implementing a hybrid cloud computing model. Line-of-business owners are concerned that data stored in the cloud may not be available to on-premises applications. The current network connection is using a maximum of 40 percent of bandwidth. What would you suggest to mitigate the risk of that kind of service failure?

9. Line-of-business owners have decided to move several applications to the cloud. They believe the cloud will be more reliable, but they want to collect data to test their hypothesis. What is a common measure of reliability that they can use?

10. TerramEarth is considering building an analytics database and making it available to equipment designers. The designers require the ability to query the data with SQL. The analytics database manager wants to minimize the cost of the service. What would you recommend?

11. Your company is running multiple VM instances that have not had any downtime in the past several weeks. Recently, several of the physical servers suffered disk failures. The applications running on the servers did not have any apparent service disruptions. What feature of Compute Engine enabled that?

12. Your company is implementing a hybrid cloud computing model. Line-of-business owners are concerned that data stored in the cloud may not be available to on-premises applications. The current network connection is using a maximum of 40 percent of bandwidth. What would you suggest to mitigate the risk of that kind of service failure?

13. Kubernetes uses several abstractions to model and manage computation and applications. What is the progression of abstractions from the lowest to the highest level ?

14. Your development team has recently triggered three incidents that resulted in service disruptions. In one case, an engineer mistyped a number in a configuration file and in the other cases specified an incorrect disk configuration. What practices would you recommend to reduce the risk of these types of errors?

15. You have deployed an application on an instance group. The application is not functioning correctly. What is a possible outcome?

16. A group of business executives and software engineers are discussing the level of risk that is acceptable for a new application. Business executives want to minimize the risk that the service is not available. Software engineers note that the more developer time dedicated to reducing risk of disruption, the less time they have to implement new features. How can you formalize the group’s tolerance for risk of disruption?

17. Kubernetes uses several abstractions to model and manage computation and applications. What is the progression of abstractions from the lowest to the highest level ?

18. TerramEarth has determined that it wants to use Cloud Bigtable to store equipment telemetry data transmitted over their cellular network. They have also concluded that they want two clusters in different regions. Both clusters should be able to respond to read and write requests. What kind of replication should be used?

19. A team of data scientists is analyzing archived data sets. The model building procedures run in batches. If the model building system is down for up to 30 minutes per day, it does not adversely impact the data scientists’ work. What is the minimal percentage availability among the following options that would meet this requirement?

20. What configuration changes are required to ensure high availability when using Cloud Storage or Cloud Filestore?
