Your application images are built using Cloud Build and pushed to Google Container Registry (GCR). You want to be able to specify a particular version of your application for deployment based on the release version tagged in source control. What should you do when you push the image?

• A.Use Cloud Build to include the release version tag in the application image.
• B.Supply the source control tag as a parameter within the image name.
• C.Reference the image digest in the source control tag.
• D.Use GCR digest versioning to match the image to the tag in source control.

You support a service with a well-defined Service Level Objective (SLO). Over the previous 6 months, your service has consistently met its SLO and customer satisfaction has been consistently high. Most of your service's operations tasks are automated and few repetitive tasks occur frequently. You want to optimize the balance between reliability and deployment velocity while following site reliability engineering best practices. What should you do? (Choose two.)

• A.Make the service's SLO more strict.
• B.Increase the service's deployment velocity and/or risk.
• C.Shift engineering time to other services that need more reliability.
• D.Get the product team to prioritize reliability work over new features.
• E.Change the implementation of your Service Level Indicators (SLIs) to increase coverage.

You support a high-traffic web application that runs on Google Cloud Platform (GCP). You need to measure application reliability from a user perspective without making any engineering changes to it. What should you do?
Choose 2 answers

• A.Review current application metrics and add new ones as needed.
• B.Modify the code to capture additional information for user interaction.
• C.Analyze the web proxy logs only and capture response time of each request.
• D.Use current and historic Request Logs to trace customer interaction with the application.
• E.Create new synthetic clients to simulate a user journey using the application.

You have a CI/CD pipeline that uses Cloud Build to build new Docker images and push them to Docker Hub.
You use Git for code versioning. After making a change in the Cloud Build YAML configuration, you notice that no new artifacts are being built by the pipeline. You need to resolve the issue following Site Reliability Engineering practices. What should you do?

• A.Run a Git compare between the previous and current Cloud Build Configuration files to find and fix the bug.
• B.Change the CI pipeline to push the artifacts is Container Registry instead of Docker Hub.
• C.Disable the CI pipeline and revert to manually building and pushing the artifacts.
• D.Upload the configuration YAML file to Cloud Storage and use Error Reporting to identify and fix the issue.

You have a pool of application servers running on Compute Engine. You need to provide a secure solution that requires the least amount of configuration and allows developers to easily access application logs for troubleshooting. How would you implement the solution on GCP?

• A.* Deploy the Stackdriver logging agent to the application servers.
  * Give the developers the IAM Logs Viewer role to access Stackdriver and view logs.
• B.* Deploy the Stackdriver logging agent to the application servers.
  * Give the developers the IAM Logs Private Logs Viewer role to access Stackdriver and view logs.
• C.* Install the gsutil command line tool on your application servers.
  * Write a script using gsutil to upload your application log to a Cloud Storage bucket, and then schedule it to run via cron every 5 minutes.
  * Give the developers IAM Object Viewer access to view the logs in the specified bucket.
• D.* Deploy the Stackdriver monitoring agent to the application servers.
  * Give the developers the IAM Monitoring Viewer role to access Stackdriver and view metrics.
