DOP-C02 Incident and Event Response Practice Question
A company is using AWS CloudFormation to deploy infrastructure. An engineer needs to ensure that any changes to the production stack are reviewed and approved before they are applied. The engineer also wants to prevent unauthorized changes. Which solution should the engineer implement?
⚠ Common exam trap
Watch out — candidates often confuse the purpose of StackSets (multi-account deployment) or CodePipeline (CI/CD pipeline) with the need for a simple change review mechanism, overlooking the direct and built-in capability of CloudFormation Change Sets to preview and require approval before applying changes.
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 CloudFormation Change Sets and require manual approval to execute the change set.
CloudFormation Change Sets allow you to preview how proposed changes to a stack will impact running resources before you apply them. By requiring manual approval to execute the change set, the engineer ensures that all modifications are reviewed and approved, preventing unauthorized changes. This directly meets the requirement for a review-and-approval workflow without introducing unnecessary complexity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use CloudFormation StackSets to manage the production stack across multiple accounts.
Why it's wrong here
StackSets are for deployment across accounts, not for change review.
- ✓
Use CloudFormation Change Sets and require manual approval to execute the change set.
Why this is correct
Change Sets allow you to review proposed changes before applying them.
- ✗
Use AWS Service Catalog to create a product for the stack and require approval for any portfolio changes.
Why it's wrong here
Service Catalog manages product portfolios, not direct stack updates.
- ✗
Use AWS CodePipeline to deploy the stack and require manual approval at the deploy stage.
Why it's wrong here
CodePipeline can include a manual approval step, but CloudFormation Change Sets provide a more native review of actual changes.
