SAP-C02 Design for New Solutions Practice Question
A company is deploying a containerized application on Amazon EKS. The application needs to access an Amazon RDS database. The security team requires that database credentials be rotated automatically and never stored in plaintext. Which solution should the architect use?
⚠ Common exam trap
Many exam-takers confuse AWS Systems Manager Parameter Store with Secrets Manager, assuming Parameter Store supports automatic rotation, but Parameter Store lacks native rotation capabilities for RDS credentials, making Secrets Manager the only correct choice for automated rotation.
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 Secrets Manager to store and rotate credentials, and grant the EKS pod access via an IAM role
AWS Secrets Manager is the correct choice because it natively supports automatic rotation of RDS database credentials via a built-in Lambda rotation function, and it integrates with IAM roles to grant EKS pods secure access without storing secrets in plaintext. By using an IAM role for the pod (via IRSA), the application can retrieve credentials at runtime from Secrets Manager, ensuring compliance with the security team's requirements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use AWS Secrets Manager to store and rotate credentials, and grant the EKS pod access via an IAM role
Why this is correct
Secrets Manager rotates credentials automatically and integrates with IAM for access.
- ✗
Use IAM database authentication for RDS and assign an IAM role to the pod
Why it's wrong here
IAM auth uses tokens, not passwords, but does not rotate credentials; it's a different approach.
- ✗
Hardcode the credentials in the container image and rotate the image regularly
Why it's wrong here
Hardcoding credentials is insecure and violates best practices.
- ✗
Store credentials in AWS Systems Manager Parameter Store and grant the EKS pod access via an IAM role
Why it's wrong here
Parameter Store stores secrets but does not rotate them automatically.
