1. You have been hired to consult with an enterprise software development that is starting to adopt agile and DevOps practices. The developers would like advice on tools that they can use to help them collaborate on software development in the Google Cloud. What version control software might you recommend?

2. As an SRE, you are assigned to support several applications. In the past, these applications have had significant reliability problems. You would like to understand the performance characteristics of the applications, so you create a set of dashboards. What kind of data would you display on those dashboards?

3. A team of software engineers is using release management practices. They want developers to check code into the central team code repository several times during the day. The team also wants to make sure that the code that is checked in is functioning as expected before building the entire application. What kind of tests should the team run before attempting to build the application?

4. Release management practices contribute to improving reliability by which one of the following?

5. After determining the optimal combination of CPU and memory resources for nodes in a Kubernetes cluster, you want to be notified whenever CPU utilization exceeds 85 percent for 5 minutes or when memory utilization exceeds 90 percent for 1 minute. What would you have to specify to receive such notifications?

6. A service has detected that a downstream process is returning a large number of errors. The service automatically slows down the number of messages it sends to the downstream process. This is an example of what kind of strategy?

7. A service is experiencing unexpectedly high volumes of traffic. Some components of the system are able to keep up with the workload, but others are unable to process the volume of requests. These services are returning a large number of internal server errors. Developers need to release a patch as soon as possible that provides some relief for an overloaded relational database service. Both memory and CPU utilization are near 100 percent. Horizontally scaling the relational database is not an option, and vertically scaling the database would require too much downtime. What strategy would be the fastest to implement?

8. A compliance review team is seeking information about how your team handles high-risk administration operations, such as granting operating system users root privileges. Where could you find data that shows your team tracks changes to user privileges?

9. A startup offers a software-as-a-service solution for enterprise customers. Many of the components of the service are stateful, and the system has not been designed to allow incremental rollout of new code. The entire environment has to be running the same version of the deployed code. What deployment strategy should they use?

10. Developers have just deployed a code change to production. They are not routing any traffic to the new deployment yet, but they are about to send a small amount of traffic to servers running the new version of code. What kind of deployment are they using?
