- A
Configure Cloud Monitoring alerting policy on deployment errors that triggers a Cloud Function to rollback.
Why wrong: While you can use Cloud Monitoring alerts to trigger a Cloud Function for rollback, this is not a native Cloud Deploy feature and requires custom development.
- B
Set up a Cloud Build trigger that detects deployment failure and runs a rollback.
Why wrong: Cloud Build triggers are designed for building and testing, not for automated rollback of deployments.
- C
Configure a Cloud Deploy rollout strategy with an automated rollback policy.
Cloud Deploy's rollbackPolicy enables automated rollback on failure, making it a native and integrated solution.
- D
Use a Cloud Deploy rollout strategy with a post-deploy hook that calls Cloud Run jobs to revert.
Why wrong: Post-deploy hooks run after a successful deployment and are not intended for automatic rollback on failure.
PCDOE Building and implementing CI/CD pipelines Practice Question
This PCDOE practice question tests your understanding of building and implementing ci/cd pipelines. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
A company uses Cloud Deploy for continuous delivery to GKE. They have a delivery pipeline with a rollout strategy: canary (25% for 30m) then full. The canary rollout fails because the new revision's health check errors. The team wants to automatically rollback the canary and notify. What native GCP feature can achieve this?
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
Configure a Cloud Deploy rollout strategy with an automated rollback policy.
Option C is correct because Cloud Deploy supports automated rollback through its rollbackPolicy configuration in the delivery pipeline. When a rollout fails health checks, the rollbackPolicy can automatically initiate a rollback to the previous successful revision. Additionally, Cloud Deploy can integrate with Cloud Monitoring or Pub/Sub to send notifications. Option A is incorrect because while you can set up an alert and Cloud Function, that is not a native feature of Cloud Deploy and requires custom implementation. Option B is incorrect because Cloud Build triggers are meant for building and testing, not for rollback automation. Option D is incorrect because post-deploy hooks are for custom actions after deployment, not for automatic rollback on failure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
