- A
Configure a Lambda function to validate commits and block pushes.
Why wrong: Lambda can be used but is not the native feature.
- B
Enable branch protection rules on the repository.
Why wrong: CodeCommit does not have built-in branch protection like GitHub.
- C
Create an approval rule template and associate it with the main branch.
Approval rules require pull request approvals before merging.
- D
Use CloudWatch Events to notify when a push occurs.
Why wrong: Notifications do not enforce reviews.

DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 wants to ensure that all code changes are reviewed before being merged to the main branch in AWS CodeCommit. Which feature should be enabled?
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
✓
Create an approval rule template and associate it with the main branch.
Option C is correct because AWS CodeCommit does not natively support branch protection rules like GitHub or GitLab. Instead, you must create an approval rule template and associate it with the main branch to require at least one approved pull request before merging. This ensures all code changes are reviewed before being merged to the main branch.
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
The trap here is that candidates familiar with GitHub or GitLab mistakenly expect 'branch protection rules' (Option B) to exist in CodeCommit, but AWS CodeCommit requires approval rule templates instead, and the exam tests this platform-specific difference.
Detailed technical explanation
How to think about this question
Approval rule templates in CodeCommit are evaluated when a pull request is created or updated; they require a minimum number of approvals from specified IAM users or groups before the pull request can be merged. Under the hood, CodeCommit uses AWS IAM policies and the 'codecommit:CreatePullRequestApprovalRule' action to enforce these rules, and the merge is blocked until the approval conditions are met. In a real-world scenario, you might combine this with a 'deny' IAM policy on the main branch to prevent direct pushes, ensuring all changes go through the approval workflow.
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.
TExam Day Tips
- 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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
