The answer is to use AWS Secrets Manager and IAM roles to protect secrets in a CI/CD pipeline. This is correct because Secrets Manager provides a secure, centralized service to store and automatically rotate sensitive data like API keys, while IAM roles allow the CI/CD service to assume a temporary, scoped permission to retrieve those secrets without ever hardcoding them into code or configuration files. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this concept tests your understanding of the principle of least privilege and the separation of secrets from pipeline artifacts—a common trap is selecting “store secrets in environment variables” or “encrypt with KMS” alone, but the exam requires the two-part best practice of using a dedicated secrets manager plus role-based access. A useful memory tip is “Secrets Manager stores, IAM roles grants”—if you remember that secrets should never be embedded and access should always be assumed, you will avoid the hardcoding pitfall.
DOP-C02 Security and Compliance Practice Question
This DOP-C02 practice question tests your understanding of security and compliance. 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.
A company is designing a secure CI/CD pipeline. Which TWO actions should be taken to protect secrets (e.g., API keys) used in the pipeline? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Store secrets in AWS Secrets Manager
AWS Secrets Manager stores and rotates secrets securely. IAM roles should be used to grant access to secrets without hardcoding. Storing secrets in buildspec or environment variables is insecure. Using KMS to encrypt secrets is good, but the question asks for TWO best practices: using Secrets Manager and IAM roles.
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.
✗
Encrypt secrets with AWS KMS and store the encrypted value in the source code
Why it's wrong here
Storing encrypted secrets in source code is still risky if the key is compromised.
✓
Store secrets in AWS Secrets Manager
Why this is correct
Secrets Manager provides secure storage and rotation.

✗
Store secrets in plaintext in the buildspec file
Why it's wrong here
Plaintext in buildspec is insecure.
✗
Pass secrets as environment variables in the build
Why it's wrong here
Environment variables can be exposed in logs.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
