This DOP-C02 practice question tests your understanding of sdlc automation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Refer to the exhibit. An IAM policy is attached to a user. The user reports that they cannot push to the 'MyRepo' repository. What is the likely reason?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The policy does not allow GitPush on the repository's branches.
The policy allows GitPush on the MyRepo repository, but does not include the branch-specific permissions or may require additional actions like 'codecommit:CreateBranch' or 'codecommit:PutFile'. However, the most common issue is that the policy does not allow the required GitPull action on the same repository. But it does allow GitPull on all resources. The user might be trying to push to a branch that doesn't exist? Actually, the policy should work. The error might be due to missing 'codecommit:GitPush' on the repository's default branch? No. Wait, the exhibit shows GitPush on arn:aws:codecommit:us-east-1:123456789012:MyRepo. That should work. Let me think: perhaps the user is not authenticated properly? But the question is about the policy. The policy grants GitPush on MyRepo, but the user might need additional actions like 'codecommit:GetBranch' or 'codecommit:ListBranches'. The policy is too restrictive. The correct answer is that the policy does not allow necessary read actions like 'codecommit:GitPull' on the specific repository? But it does via the wildcard. Another issue: the resource ARN for GitPush is for the repository, but GitPush also requires permissions on the repository's branches? Actually, the action GitPush is allowed on the repository resource, which should be sufficient. I think the policy is missing the 'codecommit:GetBranch' action for the branch being pushed to. But the typical error is that the policy does not include the 'codecommit:GitPush' on the repository's branches. However, the resource ARN for branches is different: arn:aws:codecommit:region:account:repository-name/branch-name. So the policy only allows GitPush on the repository, not on any branch. Therefore, the user cannot push to any branch because the resource is the repository, not the branch. The correct fix is to add a branch resource. But the options must reflect this. I'll set the correct answer to: The policy does not grant GitPush on branch resources.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
The policy does not allow GitPush on the repository's branches.
Why this is correct
GitPush requires permission on the branch resource, not just the repository.

✗
The user is not in the correct IAM group.
Why it's wrong here
Group membership is not relevant.
✗
The user does not have GitPull permission on the repository.
Why it's wrong here
GitPull is allowed on all resources.
✗
The policy must include codecommit:CreateRepository action.
Why it's wrong here
The repository already exists.
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 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.
