DOP-C02 SDLC Automation Practice Question
A development team uses AWS CodeCommit to store their application code. They want to enforce that all code changes to the main branch are reviewed and approved by at least one other team member before being merged. Which AWS service or feature should they use to implement this requirement?
⚠ Common exam trap
It's easy for candidates to confuse deployment approval (CodePipeline manual approval) with code review approval (CodeCommit approval rules), which serve different purposes.
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
✓
AWS CodeCommit approval rule templates
CodeCommit approval rule templates define the number of approvals required for a pull request to be merged. By applying a template to the repository, you can enforce that at least one approval is needed before merging into the main branch. This is the native feature for implementing mandatory code reviews in CodeCommit.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Identity and Access Management (IAM) policies
Why it's wrong here
IAM policies control access to CodeCommit actions, such as who can push or create branches. They cannot enforce that a pull request must be approved before merging. While you could restrict direct pushes to the main branch, you cannot use IAM to require an approval step in the pull request process.
- ✗
AWS CodePipeline manual approval action
Why it's wrong here
A manual approval action in CodePipeline pauses a pipeline for approval, but it does not prevent code from being merged into the main branch. It is used for deployment approvals, not for code review enforcement. Code can still be merged without approval, and the pipeline would only be triggered after the merge.
- ✓
AWS CodeCommit approval rule templates
Why this is correct
Approval rule templates in CodeCommit allow you to define the number of approvals required for a pull request to be merged. You can apply a template to a repository to enforce that at least one approval is needed before merging into the main branch. This directly meets the requirement for mandatory code review.
- ✗
AWS CodeCommit repository triggers
Why it's wrong here
Repository triggers in CodeCommit are used to send notifications or invoke Lambda functions in response to repository events like pushes. They do not enforce approval workflows or block merges. Triggers are for automation, not for access control or review enforcement. They cannot prevent a merge without approval.
