- A
Configure the approval action to invoke an AWS Lambda function that validates the approver's IAM role tags.
This allows custom authorization based on tags.
- B
Enable AWS CloudTrail to log all approval API calls for auditing.
CloudTrail logs all API calls, including approval actions.
- C
Use Amazon Simple Notification Service (SNS) to send approval notifications and allow any subscriber to approve.
Why wrong: SNS does not enforce authorization.
- D
Use AWS CodeCommit to manage approval permissions via repository policies.
Why wrong: CodeCommit permissions are for source code, not pipeline approvals.
- E
Store approval logs in Amazon CloudWatch Logs for real-time monitoring.
Why wrong: CloudWatch Logs is for log storage, not API auditing.

DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. 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.
An organization has a AWS CodePipeline that deploys a critical application. The pipeline uses a manual approval step before deploying to production. The team wants to ensure that only authorized users can approve the deployment, and that the approval action is logged for compliance. Which combination of actions should the team take? (Select TWO.)
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
✓
Configure the approval action to invoke an AWS Lambda function that validates the approver's IAM role tags.
Option A is correct because AWS CodePipeline's manual approval action can be configured to invoke an AWS Lambda function that checks the approver's IAM role tags, ensuring only authorized users (e.g., those with a specific 'approver' tag) can approve. This provides fine-grained, custom authorization beyond basic IAM policies. Option B is correct because enabling AWS CloudTrail captures all approval API calls (e.g., PutApprovalResult) as audit logs, meeting compliance requirements for tracking who approved and when.
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 often confuse CloudWatch Logs (for monitoring) with CloudTrail (for auditing), or mistakenly think CodeCommit can manage pipeline permissions, when in fact CodePipeline's approval actions require IAM-based or Lambda-based authorization, not repository policies.
Detailed technical explanation
How to think about this question
Under the hood, the Lambda function in option A can use the IAM client's 'get-user' or 'list-role-tags' API to verify the approver's tags, then call 'codepipeline:put_approval_result' with the token from the pipeline. CloudTrail logs every 'PutApprovalResult' call as an event in the management event trail, including the IAM user ARN, source IP, and timestamp, which can be queried via Athena or CloudTrail Lake for compliance reports. A real-world scenario is a financial services firm that must enforce separation of duties, where only senior engineers with a 'role=senior-approver' tag can approve production deployments.
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.
