Google Cloud Professional Machine Learning Engineer — Question 36

You have written unit tests for a Kubeflow Pipeline that require custom libraries. You want to automate the execution of unit tests with each new push to your development branch in Cloud Source Repositories. What should you do?

Answer options

• A. Write a script that sequentially performs the push to your development branch and executes the unit tests on Cloud Run.
• B. Using Cloud Build, set an automated trigger to execute the unit tests when changes are pushed to your development branch.
• C. Set up a Cloud Logging sink to a Pub/Sub topic that captures interactions with Cloud Source Repositories. Configure a Pub/Sub trigger for Cloud Run, and execute the unit tests on Cloud Run.
• D. Set up a Cloud Logging sink to a Pub/Sub topic that captures interactions with Cloud Source Repositories. Execute the unit tests using a Cloud Function that is triggered when messages are sent to the Pub/Sub topic.

Correct answer: B

Explanation

The correct answer is B because Cloud Build is specifically designed to automate the execution of tasks such as running unit tests upon code changes in Cloud Source Repositories. Option A lacks automation for triggering tests upon pushes, while options C and D involve additional steps and components that complicate the process unnecessarily compared to the direct approach of using Cloud Build.
