- A
Set an automatic rollback policy in the delivery pipeline definition
Correct. The delivery pipeline definition supports a `rollback_policy` that automatically rolls back on deploy failure.
- B
Use a Cloud Build post-deploy hook to check the rollout status and roll back if needed
Why wrong: Incorrect. While a Cloud Build post-deploy hook could be used, it is unnecessary because Cloud Deploy provides a native rollback policy.
- C
Configure the approval gate to reject the deployment if it fails
Why wrong: Incorrect. Approval gates are for manual approval and do not trigger automatic rollbacks.
- D
Enable the 'rollback on failure' flag in the pipeline
Why wrong: Incorrect. There is no 'rollback on failure' flag in the pipeline definition.

Google PCA Cloud Deploy rollback policy Practice Question
This PCA practice question tests your understanding of managing and provisioning a solution infrastructure. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: cloud Deploy rollback policy. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
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.

Common exam trap: answer the scenario, not the keyword
Candidates may assume Cloud Deploy lacks automated rollback, but it actually supports it via a pipeline-level rollback policy.
