DVA-C02 Development with AWS Services Practice Question
This DVA-C02 practice question tests your understanding of development with aws services. 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 using AWS CodePipeline to automate its CI/CD pipeline. The pipeline has a build stage that uses AWS CodeBuild. The developer wants to run unit tests and only proceed to the deploy stage if the tests pass. Which configuration should the developer use 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
✓
Configure the build stage to run tests and fail the build if tests fail; CodePipeline will automatically stop.
CodeBuild can be configured with a buildspec file that defines phases, including a 'post_build' phase for running tests. If the tests fail, CodeBuild returns a non-zero exit code, causing the build to fail. CodePipeline will then stop and not proceed to the deploy stage. The developer can also use a 'test' action in CodePipeline with a test provider like CodeBuild. The other options either don't stop the pipeline or are not automated.
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 manual approval step before the deploy stage.
Why it's wrong here
Manual approval requires human intervention, not automated based on test results.
✗
Configure Amazon CloudWatch alarms to stop the pipeline if tests fail.
Why it's wrong here
CloudWatch alarms can notify but not directly stop the pipeline.
✓
Configure the build stage to run tests and fail the build if tests fail; CodePipeline will automatically stop.
Why this is correct
Tests in the build stage can fail the build, preventing deployment.

Read the scenario before looking for a memorised answer.
✗
Configure AWS Lambda to invoke a function that checks test results and manually stops the pipeline.
Why it's wrong here
This is more complex and not a standard configuration.
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.
