- A
Deploy using Spinnaker on GKE with a canary pipeline that includes an automated rollback step.
Why wrong: Spinnaker is an additional tool, not a Google-native solution.
- B
Configure a Cloud Build step to monitor the canary and rollback if needed.
Why wrong: Manual monitoring via build step is not automatic or robust.
- C
Use a GKE rolling update strategy within the deployment manifest.
Why wrong: Rolling update is not canary; it updates pods gradually but doesn't support automated rollback based on metrics.
- D
Set up Cloud Deploy with a rollout strategy that uses Cloud Monitoring metrics to automatically rollback.
Cloud Deploy can use a 'canary' strategy with metrics-based promotion/rollback.

PCDOE Building and implementing CI/CD pipelines Practice Question
This PCDOE practice question tests your understanding of building and implementing ci/cd pipelines. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 team implements canary deployments using Cloud Deploy and deploys to GKE. They want to automatically roll back if the canary release's error rate exceeds 5% within 10 minutes. Which approach should they use?
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 up Cloud Deploy with a rollout strategy that uses Cloud Monitoring metrics to automatically rollback.
Option D is correct. Cloud Deploy can leverage Cloud Monitoring metrics as part of a rollout strategy to automatically roll back a canary deployment when the error rate exceeds a defined threshold (e.g., 5% within 10 minutes). Options A is incorrect because Spinnaker is not native to GCP and does not integrate seamlessly with Cloud Deploy; also Spinnaker is not the recommended tool for this scenario. Option B is incorrect because Cloud Build is intended for building and testing artifacts, not for real-time monitoring and rollback of deployments. Option C is incorrect because a rolling update strategy does not support canary deployments or metric-based automatic rollback; it simply replaces pods gradually.
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.
