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 company is using AWS CodePipeline to automate deployments. The pipeline has a source stage that retrieves code from an S3 bucket, a build stage using CodeBuild, and a deploy stage using CodeDeploy. The build stage sometimes fails due to intermittent network issues. Which TWO actions would make the pipeline more resilient to such failures?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable retry on the build stage to automatically attempt the build again on failure.
Enabling retry on the build stage allows the pipeline to automatically retry on failure. Configuring a manual approval stage does not help with automated retries. Using a different source does not address build failures. Splitting into multiple actions adds complexity, not resilience. Storing artifacts in different bucket is not relevant.
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.
✓
Enable retry on the build stage to automatically attempt the build again on failure.
Why this is correct
Retry can handle transient failures.
Related concept
Read the scenario before looking for a memorised answer.
✗
Store build artifacts in a different S3 bucket.
Why it's wrong here
Artifact storage location does not affect build failures.
✗
Add a manual approval stage before the build stage.
Why it's wrong here
Manual approval does not automate retries.
✗
Configure the build stage to run multiple build actions in parallel.
Why it's wrong here
Parallel actions do not retry on failure.
✗
Use a different source repository, such as CodeCommit.
Why it's wrong here
Source type does not affect build stage resilience.
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 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.
