- A
Add a test stage in the pipeline with a CodeBuild action that runs code quality and unit tests.
This adds automated testing in the pipeline.
- B
Add a manual approval step before the deploy stage.
Why wrong: Manual approval does not run tests.
- C
Modify the buildspec file of the build stage to include test commands and fail on test failures.
This ensures the build stage itself runs tests.
- D
Configure the source stage to use an S3 bucket and add a test action.
Why wrong: S3 is a storage service, not a test runner.
- E
Use AWS CloudFormation to create a test environment and run tests.
Why wrong: CloudFormation provisions resources, not run tests.

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 company is implementing a CI/CD pipeline using AWS CodePipeline. The pipeline has a source stage from GitHub, a build stage using AWS CodeBuild, and a deploy stage using AWS Elastic Beanstalk. The team wants to ensure that the pipeline only proceeds if the code quality checks pass and unit tests are successful. Which TWO actions should be taken?
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 the pipeline with a CodeBuild action that runs code quality and unit tests.
Option A is correct because adding a dedicated test stage with a CodeBuild action allows the pipeline to explicitly run code quality checks and unit tests as a separate, visible step. This ensures the pipeline only proceeds to deployment if these tests pass, as CodeBuild can be configured to fail the action on non-zero exit codes from test commands. Option C is also correct because modifying the buildspec file in the existing build stage to include test commands and setting the build to fail on test failures integrates quality gates directly into the build process, which is a common and valid approach for enforcing test success before deployment.
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 think a manual approval step (Option B) or infrastructure provisioning (Option E) can enforce test quality gates, but neither actually executes or validates test results automatically within the pipeline.
Detailed technical explanation
How to think about this question
CodeBuild actions in CodePipeline can be configured with a buildspec file that defines phases like 'pre_build', 'build', and 'post_build'; including test commands in the 'build' phase and using 'fail: true' on the phase ensures the build exits with a non-zero code if tests fail, causing the pipeline to stop. Under the hood, CodePipeline polls the CodeBuild project for the build status; if the build fails, the pipeline transitions to a 'Failed' state and does not proceed to the next stage. This approach is efficient because it avoids creating an extra stage, but adding a separate test stage provides clearer visibility and allows parallel test execution if needed.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
