- A
Configure a CodeCommit approval rule template to block the merge.
Why wrong: Approval rules in CodeCommit are for pull requests, not pipeline stages.
- B
Use CloudWatch Events to send a notification and wait for a custom signal.
Why wrong: CloudWatch Events cannot block pipeline execution.
- C
Set the pipeline to only run on manual invocation.
Why wrong: Manual invocation starts the pipeline, but does not provide approval within a stage.
- D
Add a manual approval action in the pipeline stage before production deployment.
Manual approval actions pause the pipeline until approved.

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 DevOps engineer is setting up a CI/CD pipeline for a microservices application using AWS CodePipeline. The pipeline includes a Test stage that runs integration tests against a staging environment. The engineer wants to ensure that manual approval is required before deploying to production. Which action should be taken?
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
✓
Add a manual approval action in the pipeline stage before production deployment.
Option D is correct because AWS CodePipeline supports a manual approval action that can be added to any stage. By placing this action in the stage immediately before the production deployment, the pipeline will pause and require an authorized user to manually approve the transition, ensuring that integration tests have passed before any production release occurs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Configure a CodeCommit approval rule template to block the merge.
Why it's wrong here
Approval rules in CodeCommit are for pull requests, not pipeline stages.
- ✗
Use CloudWatch Events to send a notification and wait for a custom signal.
Why it's wrong here
CloudWatch Events cannot block pipeline execution.
- ✗
Set the pipeline to only run on manual invocation.
Why it's wrong here
Manual invocation starts the pipeline, but does not provide approval within a stage.
- ✓
Add a manual approval action in the pipeline stage before production deployment.
Why this is correct
Manual approval actions pause the pipeline until approved.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse repository-level approval mechanisms (like CodeCommit approval rules) with pipeline-level deployment approvals, or assume that manual invocation alone satisfies the requirement for a conditional approval step.
Detailed technical explanation
How to think about this question
The manual approval action in CodePipeline uses Amazon SNS to send a notification to specified approvers and then polls for an approval or rejection via the AWS Console, CLI, or SDK. Under the hood, the pipeline execution transitions to a 'Waiting' state until the approval is granted, and the action can be configured with required approver IAM permissions and a custom SNS topic. In a real-world scenario, this pattern is often combined with a 'Deploy to Staging' stage that runs integration tests, followed by a manual approval stage, and finally a 'Deploy to Production' stage, ensuring that no code reaches production without human sign-off.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
