- A
Use AWS CloudFormation with a blue/green deployment and a CloudWatch alarm to trigger rollback.
Why wrong: CloudFormation blue/green does not automatically roll back based on health checks; it requires manual intervention.
- B
Use AWS Elastic Beanstalk with a rolling update and a CloudWatch alarm to trigger rollback.
Why wrong: Elastic Beanstalk rolling updates do not support canary traffic shifting; rollback is not automatic.
- C
Use AWS CodeDeploy with a canary deployment and a CloudWatch alarm to trigger automatic rollback.
CodeDeploy canary shifts traffic in increments and automatically rolls back if the alarm triggers.
- D
Use AWS CodePipeline with a manual approval step and a CloudWatch alarm to trigger rollback.
Why wrong: CodePipeline orchestrates stages but does not handle deployment strategies or automatic rollback.
DVA-C02 Deployment Practice Question
This DVA-C02 practice question tests your understanding of deployment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 DevOps engineer is designing a CI/CD pipeline for a microservices application. The team wants to deploy updates to the production environment gradually and automatically roll back if health checks fail. Which AWS service and deployment configuration should the engineer 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
Use AWS CodeDeploy with a canary deployment and a CloudWatch alarm to trigger automatic rollback.
Option B is correct because AWS CodeDeploy with a canary deployment allows gradual traffic shifting and automatic rollback on CloudWatch alarm failure. Option A is incorrect because CloudFormation with a blue/green deployment requires manual rollback. Option C is incorrect because Elastic Beanstalk with rolling updates does not support canary-based traffic shifting. Option D is incorrect because CodePipeline alone does not handle deployment strategies or health check-based rollbacks.
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.
