This DOP-C02 practice question tests your understanding of sdlc automation. 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 uses AWS CodePipeline with an S3 source action and a CodeBuild project. The pipeline fails intermittently during the build stage with an error indicating that the source code archive is corrupt. Which action should the DevOps engineer take to resolve this issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable versioning on the S3 bucket and use versioned objects in the pipeline.
Enabling versioning on the S3 bucket ensures that object versions are preserved, preventing corruption from overwrites. Option D is correct because using S3 source with versioning guarantees that the pipeline always retrieves the correct version.
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.
✗
Increase the timeout for the CodeBuild project.
Why it's wrong here
Timeout increase does not address corruption of the source archive.
✓
Enable versioning on the S3 bucket and use versioned objects in the pipeline.
Why this is correct
Versioning prevents corruption issues by preserving object versions.

Read the scenario before looking for a memorised answer.
✗
Configure the pipeline to use AWS CodeCommit as the source instead of S3.
Why it's wrong here
Changing source type does not fix the corruption on S3.
✗
Add a manual approval step before the build stage.
Why it's wrong here
Manual approval does not prevent corruption.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
