This DOP-C02 practice question tests your understanding of sdlc automation. 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.
Which TWO actions should a DevOps engineer take to ensure that an AWS CodeBuild project can access a private Amazon S3 bucket to download build artifacts? (Choose two.)
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 explicitly allows access from the CodeBuild project's IAM role ARN
Options A and D are correct. The CodeBuild project needs an IAM role with permissions to access the S3 bucket, and the S3 bucket policy must allow access from that role. Option B is wrong because VPC configuration is not required for S3 access. Option C is wrong because the bucket does not need to be public. Option E is wrong because CodeBuild does not use access keys.
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.
✗
Generate an access key and secret key for the CodeBuild project to use in the buildspec
Why it's wrong here
CodeBuild uses IAM roles, not access keys.
✓
Add a bucket policy that explicitly allows access from the CodeBuild project's IAM role ARN
Why this is correct
Ensures the bucket allows access from the role.

Read the scenario before looking for a memorised answer.
✗
Configure the CodeBuild project to run in a VPC with an S3 VPC endpoint
Why it's wrong here
Not necessary for S3 access; CodeBuild can access S3 without VPC.
✓
Attach an IAM role to the CodeBuild project with s3:GetObject permissions for the bucket
Why this is correct
The role provides permissions to download objects.

✗
Make the S3 bucket publicly readable
Why it's wrong here
Public access is insecure and not required.
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.
