The answer is to configure CodeBuild to store artifacts in S3 and use an S3 lifecycle policy to delete objects after a certain number of days. This works because CodeBuild can directly output build artifacts to a specified S3 bucket, and an S3 lifecycle rule with an expiration action automatically removes objects older than a defined threshold, ensuring only the latest successful build artifacts are retained. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of combining CodeBuild artifact configuration with S3 lifecycle management for cost-effective CI/CD pipelines. A common trap is confusing artifact storage with source code repositories like CodeCommit or log retention in CloudWatch Logs—remember that artifacts are build outputs, not source or logs. Memory tip: "Build to S3, expire with lifecycle—keep only the latest, save the cost."
DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. 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 uses AWS CodeBuild to run tests as part of their CI/CD pipeline. They want to store build artifacts in an S3 bucket and ensure that only the latest successful build artifacts are retained. Which TWO actions should they take? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure CodeBuild to output artifacts to a specific S3 bucket.
Options B and D are correct. Option B configures CodeBuild to store artifacts in S3. Option D sets a lifecycle policy to expire old artifacts. Option A is wrong because it would retain all artifacts. Option C is wrong because CodeCommit is for source code, not artifacts. Option E is wrong because CloudWatch Logs are for logs, not artifacts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Store artifacts in an AWS CodeCommit repository.
Why it's wrong here
CodeCommit is for source code, not artifacts.
✗
Enable versioning on the S3 bucket to keep all versions.
Why it's wrong here
Versioning retains all versions, not just the latest.
✗
Use CloudWatch Logs to store build logs.
Why it's wrong here
Logs are not artifacts.
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.
