- A
Require multi-factor authentication (MFA) for pipeline executions.
Why wrong: MFA is for user authentication, not pipeline runs.
- B
Use AWS KMS to encrypt artifacts in the pipeline.
Encrypts sensitive data in transit and at rest.
- C
Use AWS CodePipeline with a customer-managed S3 bucket for artifacts and restrict bucket access.
Restricting bucket access prevents unauthorized access to artifacts.
- D
Enable pipeline-level IAM permissions to restrict who can modify the pipeline.
Prevents unauthorized modifications.
- E
Enable AWS CloudTrail to log pipeline executions.
Why wrong: Logging is good for auditing but does not directly secure the pipeline.
Question 111 of 1,750
Security Best Practices for AWS CodePipeline (KMS, S3, IAM)
This DOP-C02 practice question tests your understanding of sdlc automation. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 THREE actions should a DevOps team take to ensure a CI/CD pipeline using AWS CodePipeline is secure? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS KMS to encrypt artifacts in the pipeline.
Option B is correct because AWS CodePipeline can use AWS KMS customer-managed keys (CMKs) to encrypt artifacts stored in S3 or other supported stores. This ensures that pipeline artifacts are encrypted at rest and in transit, protecting sensitive data from unauthorized access. By default, CodePipeline uses an AWS-managed key, but using a customer-managed KMS key gives the team full control over encryption, key rotation, and access policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse logging (CloudTrail) with security controls, or assume MFA can be directly enforced on pipeline executions, when in fact the correct security measures involve encryption, access control on artifacts, and IAM permissions on the pipeline resource itself.
Detailed technical explanation
How to think about this question
When using a customer-managed S3 bucket for artifacts (Option C), the bucket policy must explicitly allow the CodePipeline service principal (codepipeline.amazonaws.com) to put and get objects, and the KMS key policy must grant decrypt permissions to the CodePipeline service role. Pipeline-level IAM permissions (Option D) are enforced via resource-based policies on the pipeline resource, allowing fine-grained control over who can update, delete, or execute the pipeline. A common real-world scenario is a multi-account setup where the artifact bucket is in a shared services account, requiring cross-account KMS key grants and bucket policies.
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.
TExam Day Tips
- 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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |

Same concept, more angles
1 more ways this is tested on DOP-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO actions can be used to improve the security of a CI/CD pipeline that uses AWS CodePipeline? (Choose two.)
medium- ✓ A.Enable encryption for artifacts stored in the pipeline's S3 bucket.
- ✓ B.Use cross-account actions with appropriate IAM roles to limit access.
- C.Configure the source action to poll for changes instead of using webhooks.
- D.Store secrets in the pipeline environment variables in plain text.
- E.Use a single IAM role for all pipeline actions to simplify permissions.
Why A: Option A is correct because AWS CodePipeline stores artifacts in an S3 bucket, and enabling default encryption (SSE-S3 or SSE-KMS) ensures that all objects at rest are encrypted, protecting sensitive build outputs and source code from unauthorized access if the bucket is compromised. This is a fundamental security best practice for data at rest in any CI/CD pipeline.
