DVA-C02 Development with AWS Services Practice Question
This DVA-C02 practice question tests your understanding of development with aws services. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 developer is using AWS CodePipeline to automate CI/CD. The pipeline has a Source stage (CodeCommit), a Build stage (CodeBuild), and a Deploy stage (CodeDeploy). The Build stage runs tests and packages the application. The developer notices that the Deploy stage is triggered even when the Build stage fails. How can the developer prevent deployment on build failure?
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 with 'On failure: Abort' in the pipeline settings.
CodePipeline transitions automatically unless a stage fails. Option A is correct because setting 'On failure: Abort' will stop the pipeline. Option B is incorrect because notifications do not prevent transition. Option C is incorrect because transitions are between stages, not within. Option D is incorrect because manual approval is not automatic.
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.
✗
Set a transition between Build and Deploy stages that only allows successful builds.
Why it's wrong here
Transitions control manual approval, not automatic failure handling.
✗
Add a manual approval action before Deploy stage.
Why it's wrong here
Manual approval would still require human intervention and does not automatically fail.
✗
Add a CloudWatch Events rule to trigger a Lambda function that stops the pipeline on build failure.
Why it's wrong here
This would add complexity and is not necessary.
✓
Configure the Build stage with 'On failure: Abort' in the pipeline settings.
Why this is correct
Aborting the pipeline on failure stops further stages.

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.
