DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. 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 uses AWS CodePipeline to deploy a serverless application with AWS Lambda and Amazon API Gateway. The pipeline includes a beta and a production stage. The DevOps team wants to automatically promote the application from beta to production after successful testing. Which action should be taken in the pipeline?
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 step between the beta and production stages
Option C is correct because CodePipeline requires an explicit manual approval action to gate promotions between stages. Without a manual approval step, the pipeline would automatically transition from beta to production upon successful testing, which bypasses the necessary human validation for production deployments. Adding a manual approval step ensures that a designated approver reviews the beta stage results before promoting to production, aligning with safe deployment practices.
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 CloudWatch Events rule to automatically trigger the production deployment after beta completion
Why it's wrong here
This bypasses the manual approval requirement.
✗
Use AWS CodeDeploy to create a deployment group that promotes the application
Why it's wrong here
CodeDeploy handles deployments but not pipeline manual approval.
✓
Add a manual approval step between the beta and production stages
Why this is correct
Manual approval action allows human review before promotion.

✗
Configure an AWS Config rule to automatically approve the promotion
Why it's wrong here
Config is for resource compliance, not pipeline approval.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse event-driven triggers (CloudWatch Events) or compliance checks (AWS Config) with the need for a human-in-the-loop approval gate, overlooking that CodePipeline's native manual approval action is the only way to pause and require explicit authorization between stages.
Detailed technical explanation
How to think about this question
CodePipeline manual approval actions use Amazon SNS to notify approvers and require a token-based approval mechanism via the AWS SDK or console. The pipeline execution pauses at the approval stage until an approver calls the PutApprovalResult API with either 'Approved' or 'Rejected' status. This is critical for regulated environments where production deployments must undergo change management review, as it provides an auditable trail of who approved the promotion and when.

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.
