Google PCA Cloud Deploy rollback policy Practice Question
You have a Cloud Deploy delivery pipeline with an approval gate. You want to automatically roll back a release if the rollout fails during the deploy step. How should you configure the pipeline?
⚠ Common exam trap
Candidates may assume Cloud Deploy lacks automated rollback, but it actually supports it via a pipeline-level rollback policy.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set an automatic rollback policy in the delivery pipeline definition
Cloud Deploy does have a built-in automatic rollback feature via the `rollback_policy` in the delivery pipeline definition. Setting this policy automatically rolls back a release if the rollout fails during the deploy step. Option B describes a custom solution that is unnecessary because the native policy exists. Option C is incorrect because approval gates are for manual approval and cannot automatically trigger a rollback. Option D is incorrect because no such global flag exists. Therefore, option A is correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set an automatic rollback policy in the delivery pipeline definition
Why this is correct
Correct. The delivery pipeline definition supports a `rollback_policy` that automatically rolls back on deploy failure.
- ✗
Use a Cloud Build post-deploy hook to check the rollout status and roll back if needed
Why it's wrong here
Incorrect. While a Cloud Build post-deploy hook could be used, it is unnecessary because Cloud Deploy provides a native rollback policy.
- ✗
Configure the approval gate to reject the deployment if it fails
Why it's wrong here
Incorrect. Approval gates are for manual approval and do not trigger automatic rollbacks.
- ✗
Enable the 'rollback on failure' flag in the pipeline
Why it's wrong here
Incorrect. There is no 'rollback on failure' flag in the pipeline definition.
