- A
Configure the Elastic Beanstalk environment to run integration tests after deployment via a custom platform hook.
Why wrong: Custom hooks require more effort and are not the simplest solution.
- B
Use Amazon CloudWatch alarms to trigger a Lambda function that runs the tests.
Why wrong: Alarms are for monitoring, not for triggering tests after deployment.
- C
Add a post-deployment script in the CodeDeploy appspec file to run tests.
Why wrong: CodeDeploy is used for EC2/on-premises, not Elastic Beanstalk.
- D
Add a test stage in CodePipeline after the deploy stage that uses CodeBuild to run integration tests.
Adding a test stage in the pipeline is straightforward and automated.

DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 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 test stage in CodePipeline after the deploy stage that uses CodeBuild to run integration tests.
Option D is correct because CodePipeline natively supports a test stage after the deploy stage, and using CodeBuild to run integration tests is the simplest and most integrated approach. This keeps the entire CI/CD workflow within CodePipeline without requiring external triggers, custom scripts, or platform hooks. CodeBuild can be configured to run tests against the deployed Elastic Beanstalk environment URL, and the pipeline will only proceed if the tests pass.
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 may confuse Elastic Beanstalk with CodeDeploy and incorrectly assume a CodeDeploy appspec file (Option C) applies, or they may overcomplicate the solution by choosing CloudWatch alarms (Option B) instead of using the built-in pipeline stage.
Detailed technical explanation
How to think about this question
CodePipeline stages execute sequentially, and a test stage after the deploy stage can use a CodeBuild project that runs a script (e.g., using curl or a test framework) against the Elastic Beanstalk environment's CNAME. The pipeline can be configured with a manual approval gate or automatic rollback on test failure. Under the hood, CodeBuild runs in an isolated container with network access to the deployed environment, and the test results are reported back to CodePipeline via the build status.
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.
