The correct answer is to enable default encryption on the S3 artifact bucket and ensure all connections use HTTPS. This configuration directly addresses the requirement to encrypt CodePipeline artifacts at rest and in transit because the S3 bucket stores all pipeline artifacts, and enabling default encryption—such as SSE-S3 or SSE-KMS—secures them at rest, while HTTPS encrypts data moving between pipeline stages. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your understanding that CodePipeline does not automatically encrypt artifacts; you must explicitly configure the S3 bucket, and that CodeCommit and CodeBuild already enforce HTTPS by default, making additional steps unnecessary. A common trap is assuming KMS encryption is automatically applied to CodePipeline artifacts, but it is not—you must set it on the bucket. Memory tip: think "Bucket first, HTTPS always" to remember that encryption at rest starts with the S3 bucket, and transit is covered by the protocol.
DOP-C02 Security and Compliance Practice Question
This DOP-C02 practice question tests your understanding of security and compliance. 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 is using AWS CodePipeline to deploy a web application. The pipeline includes a source stage (CodeCommit), a build stage (CodeBuild), and a deploy stage (CodeDeploy). The security team requires that all artifacts be encrypted at rest and in transit. Which configuration ensures encryption for all stages?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable default encryption on the S3 artifact bucket and ensure all connections use HTTPS.
Option B is correct because enabling default encryption on the S3 artifact bucket ensures encryption at rest, and using HTTPS for all endpoints ensures encryption in transit. Option A is wrong because KMS encryption for CodePipeline is not automatic. Option C is wrong because CodeCommit already uses HTTPS; additional steps not needed. Option D is wrong because encryption at rest is not automatically enabled.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable AWS KMS encryption on the CodePipeline artifact bucket and use SSH for CodeCommit.
Read the scenario before looking for a memorised answer.
✗
Encrypt the CodePipeline artifact using the pipeline's built-in encryption feature.
Why it's wrong here
CodePipeline does not have built-in encryption; uses S3.

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.

Variation 1. A company uses AWS CodePipeline to deploy a web application to an Auto Scaling group. The security team requires that all artifacts in the pipeline be encrypted at rest. The pipeline uses an S3 bucket as the artifact store. Which combination of actions should the DevOps engineer take to meet this requirement with minimal operational overhead?
hard
A.Use AWS Certificate Manager to encrypt the artifacts.
✓ B.Enable S3 default encryption with SSE-S3 on the artifact bucket.
C.Use an AWS Lambda function to encrypt artifacts after each pipeline stage.
D.Create a customer-managed KMS key and configure the pipeline to use it for artifact encryption.
Why B: Option D is correct because enabling default encryption on the S3 bucket with SSE-S3 is the simplest way to encrypt all objects at rest. Option A is wrong because SSE-KMS requires managing a KMS key and additional permissions. Option B is wrong because client-side encryption is not natively supported by CodePipeline. Option C is wrong because it only encrypts new objects, not existing; but default encryption applies to all new objects, and existing ones can be copied.
