The three actions to fix the S3 bucket access denied error in CodePipeline when deploying to Elastic Beanstalk are to verify the pipeline IAM role has s3:GetObject and s3:PutObject permissions on the artifact bucket, to add a bucket policy if the bucket is in a different AWS account, and to grant kms:Decrypt permission to the pipeline role if the artifact bucket is encrypted with AWS KMS. This error occurs because CodePipeline stores build artifacts in an S3 bucket, and the deploy stage fails when the pipeline’s service role lacks the necessary permissions to read or decrypt those objects. On the AWS Certified Developer Associate DVA-C02 exam, this scenario tests your understanding of cross-service IAM permissions and encryption integration, often appearing as a multi-select question where you must distinguish between access issues and unrelated settings like bucket versioning. A common trap is assuming the bucket name is misconfigured when the real problem is missing KMS decryption rights. Memory tip: think “Read, Cross, Decrypt” — the pipeline role needs read access, cross-account bucket policy, and decrypt permission for encrypted artifacts.
DVA-C02 Troubleshooting and Optimization Practice Question
This DVA-C02 practice question tests your understanding of troubleshooting and optimization. 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 deploy a web application. The pipeline has a source stage from GitHub and a deploy stage to Elastic Beanstalk. The deploy stage fails with the error 'The S3 bucket does not allow access to the artifact'. Which THREE actions could 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
✓
Add a bucket policy that grants the pipeline's service role access to the artifact bucket.
Option A: The artifact bucket may be in another account; setting bucket policy allows access. Option B: The pipeline role must have permissions to the bucket. Option C: If the artifact bucket is encrypted with KMS, the role needs kms:Decrypt. Option D is wrong because the bucket is already specified. Option E is wrong because versioning is not related to 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.
✗
Specify a different artifact bucket in the pipeline configuration.
Why it's wrong here
Changing bucket doesn't solve access issue.
✓
Add a bucket policy that grants the pipeline's service role access to the artifact bucket.
Why this is correct
Bucket policy can grant cross-account access.

✓
Ensure the pipeline's IAM role has s3:GetObject and s3:PutObject permissions on the artifact bucket.
Why this is correct
The role needs permissions to read and write artifacts.

✓
If the artifact bucket is encrypted with AWS KMS, ensure the pipeline role has kms:Decrypt permission.
Why this is correct
KMS encryption requires decryption permission.

✗
Enable versioning on the artifact bucket.
Why it's wrong here
Versioning doesn't affect access.
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.

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.
