The correct actions are to add a manual approval stage before each environment deployment and to configure separate pipeline stages for dev, test, and prod. This works because AWS CodePipeline’s approval action acts as a gate that pauses the pipeline at a specified stage, requiring a manual thumbs-up before proceeding to the next environment. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of stage-based deployment strategies versus branch-based ones—a common trap is thinking you need multiple pipelines or CodeBuild approval actions, but CodePipeline handles approvals natively. Remember that each environment gets its own stage, and the approval action sits right before the deploy action for that environment. A useful memory tip: “Stage before deploy, approve before joy”—the approval gate must always precede the deployment stage for each target environment.
DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. 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.
A company is designing a CI/CD pipeline using AWS CodePipeline, CodeBuild, and CodeDeploy. They need to ensure that the pipeline can deploy to multiple environments (dev, test, prod) with manual approval gates. Which TWO actions should they take? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create separate stages in the pipeline for dev, test, and prod
To implement manual approval gates, CodePipeline supports approval actions. Each environment can be a separate stage. Options B and D are correct. Option A is incorrect because one pipeline cannot have multiple branches for different environments; you would use separate pipelines or stages. Option C is incorrect because CodeDeploy deployment groups can be used for different environments, but the approval gate is in CodePipeline. Option E is incorrect because CodeBuild is for building, not for approvals.
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.
✓
Create separate stages in the pipeline for dev, test, and prod
Why this is correct
Stages allow you to sequence deployments across environments.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure a single pipeline with multiple branches in the source stage
Why it's wrong here
Each branch would typically be a separate pipeline; one pipeline usually tracks one branch.
✗
Use CodeDeploy deployment groups to represent each environment
Why it's wrong here
Deployment groups are for the target environment, but the approval must be in the pipeline.
✓
Add a manual approval stage before each environment deployment
Why this is correct
Approval stages require manual confirmation to proceed.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use CodeBuild batch builds to manage environment promotion
Why it's wrong here
Batch builds are for building multiple projects, not for environment promotion with approvals.
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 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.
