The answer is to add a test stage in CodePipeline after the deploy stage that uses CodeBuild to run integration tests. This is the simplest approach because CodePipeline natively supports sequential stages, allowing you to trigger a CodeBuild project immediately after an Elastic Beanstalk deployment completes, ensuring the integration tests run automatically against the live environment without any manual intervention or external services. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your understanding of pipeline orchestration versus monitoring or deployment tools; a common trap is confusing CloudWatch Alarms (which only monitor metrics) or CodeDeploy (which handles deployments, not testing) with the actual test execution capability. The key distinction is that CodePipeline stages are designed for sequential actions, making a post-deploy test stage the most straightforward and maintainable solution. Memory tip: think "Pipeline after deploy, CodeBuild for the test, no manual rest."
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 development team uses AWS CodeStar to set up a continuous delivery pipeline for a web application. The application is deployed to an Elastic Beanstalk environment. After a successful deployment, the team wants to automatically run integration tests against the deployed application. What is the SIMPLEST way to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add a test stage in CodePipeline after the deploy stage that uses CodeBuild to run integration tests.
Option D is correct because adding a test stage in CodePipeline after the deploy stage is the simplest approach. Option A is incorrect because manual testing is not automatic. Option B is incorrect because CloudWatch Alarms monitor metrics, not run tests. Option C is incorrect because CodeDeploy is the deployment service, not a test runner.
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 the Elastic Beanstalk environment to run integration tests after deployment via a custom platform hook.
Why it's wrong here
Custom hooks require more effort and are not the simplest solution.
✗
Use Amazon CloudWatch alarms to trigger a Lambda function that runs the tests.
Why it's wrong here
Alarms are for monitoring, not for triggering tests after deployment.
✗
Add a post-deployment script in the CodeDeploy appspec file to run tests.
Why it's wrong here
CodeDeploy is used for EC2/on-premises, not Elastic Beanstalk.
✓
Add a test stage in CodePipeline after the deploy stage that uses CodeBuild to run integration tests.
Why this is correct
Adding a test stage in the pipeline is straightforward and automated.

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.
