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 a build and deploy process. The pipeline has a build stage that uses AWS CodeBuild and a deploy stage that uses AWS CodeDeploy. The build stage produces a build artifact that is stored in Amazon S3. The deploy stage fails with 'NoSuchKey' error. What is the MOST likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The pipeline does not have an OutputArtifact configured for the build stage, so the artifact is not passed to the deploy stage.
Option B is correct because the artifact must be passed explicitly between stages via the OutputArtifacts and InputArtifacts configuration. Option A is wrong because S3 bucket policy is not typically the issue for cross-account same account. Option C is wrong because CodeBuild permissions are separate. Option D is wrong because CodeDeploy permissions are for deployment, not artifact access.
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.
✗
The CodeDeploy application does not have the correct service role.
Why it's wrong here
Incorrect: The error is about missing artifact, not permissions.
✗
The CodeBuild project does not have permissions to upload to the S3 bucket.
Why it's wrong here
Incorrect: CodeBuild uploads the artifact, but the error is in deploy stage.
✓
The pipeline does not have an OutputArtifact configured for the build stage, so the artifact is not passed to the deploy stage.
Why this is correct
Correct: Artifacts must be defined in the pipeline configuration.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The S3 bucket policy does not allow CodePipeline to access the artifact.
Why it's wrong here
Incorrect: CodePipeline uses a service role, not bucket policy.
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.
