You support a production service that runs on a single Compute Engine instance. You regularly need to spend time on recreating the service by deleting the crashing instance and creating a new instance based on the relevant image. You want to reduce the time spent performing manual operations while following Site Reliability Engineering principles. What should you do?

1. A. File a bug with the development team so they can find the root cause of the crashing instance.
2. B. Create a Managed Instance Group with a single instance and use health checks to determine the system status.
3. C. Add a Load Balancer in front of the Compute Engine instance and use health checks to determine the system status.
4. D. Create a Stackdriver Monitoring dashboard with SMS alerts to be able to start recreating the crashed instance promptly after it has crashed.

Correct Answer: B

You deploy a new release of an internal application during a weekend maintenance window when there is minimal user traffic. After the window ends, you learn that one of the new features isn't working as expected in the production environment. After an extended outage, you roll back the new release and deploy a fix. You want to modify your release process to reduce the mean time to recovery so you can avoid extended outages in the future. What should you do?

1. A. Before merging new code, require 2 different peers to review the code changes.
2. B. Adopt the blue/green deployment strategy when releasing new code via a CD server.
3. C. Integrate a code linting tool to validate coding standards before any code is accepted into the repository.
4. D. Require developers to run automated integration tests on their local development environments before release.
5. E. Configure a CI serve
6. F. Add a suite of unit tests to your code and have your CI server run them on commit and verify any changes.

Correct Answer: BE

Your application services run in Google Kubernetes Engine (GKE). You want to make sure that only images from your centrally-managed Google Container Registry (GCR) image registry in the altostrat-images project can be deployed to the cluster while minimizing development time. What should you do?

1. A. Create a custom builder for Cloud Build that will only push images to gcr.io/altostrat-images.
2. B. Use a Binary Authorization policy that includes the whitelist name pattern gcr.io/attostrat-images/.
3. C. Add logic to the deployment pipeline to check that all manifests contain only images from gcr.io/altostrat-images.
4. D. Add a tag to each image in gcr.io/altostrat-images and check that this tag is present when the image is deployed.

Correct Answer: B

You support a stateless web-based API that is deployed on a single Compute Engine instance in the
europe-west2-a zone . The Service Level Indicator (SLI) for service availability is below the specified Service Level Objective (SLO). A postmortem has revealed that requests to the API regularly time out. The time outs are due to the API having a high number of requests and running out memory. You want to improve service availability. What should you do?

1. A. Change the specified SLO to match the measured SLI.
2. B. Move the service to higher-specification compute instances with more memory.
3. C. Set up additional service instances in other zones and load balance the traffic between all instances.
4. D. Set up additional service instances in other zones and use them as a failover in case the primary instance is unavailable.

Correct Answer: C

You are creating and assigning action items in a postmodern for an outage. The outage is over, but you need to address the root causes. You want to ensure that your team handles the action items quickly and efficiently. How should you assign owners and collaborators to action items?

1. A. Assign one owner for each action item and any necessary collaborators.
2. B. Assign multiple owners for each item to guarantee that the team addresses items quickly
3. C. Assign collaborators but no individual owners to the items to keep the postmortem blameless.
4. D. Assign the team lead as the owner for all action items because they are in charge of the SRE team.
