- A
Add a stage that runs a performance or load test.
Load testing validates performance.
- B
Add a stage that automatically rolls back the deployment if tests fail.
Why wrong: Rollback is a recovery action, not a testing step.
- C
Add a manual approval stage after testing before promoting to production.
Manual approval allows review.
- D
Add a stage that deploys the application to a separate production environment.
Why wrong: Not a testing step.
- E
Add a stage after deployment that runs integration tests against the deployed API.
Integration tests validate the deployment.

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 company uses AWS CodePipeline to deploy a serverless application using AWS SAM. The pipeline includes a build stage that runs 'sam build' and a deploy stage that runs 'sam deploy'. The team wants to automatically test the deployed application before promoting it to production. Which THREE steps should be included in the pipeline?
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 stage that runs a performance or load test.
Option A is correct because adding a performance or load test stage after deployment validates that the serverless application can handle expected traffic volumes under AWS SAM's provisioned concurrency and scaling limits. This ensures the application meets non-functional requirements before promotion, catching issues like cold start latency or throttling that unit tests miss.
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 confuse automatic rollback (Option B) with a valid pipeline step, but AWS CodePipeline requires explicit actions for rollback, and the question specifically asks for steps to include, not automated recovery mechanisms.
Detailed technical explanation
How to think about this question
Under the hood, AWS SAM uses AWS CloudFormation change sets to manage deployments; 'sam deploy' executes a change set that can be rolled back if tests fail, but CodePipeline does not natively trigger rollback without a custom action. In practice, teams often use a Lambda function in the pipeline to run integration tests against the API Gateway endpoint (e.g., using the SDK to invoke the API and validate responses), and a manual approval stage ensures a human verifies test results before the pipeline proceeds to production promotion.
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.
