The correct solution is to use AWS Secrets Manager to store and rotate credentials, granting the EKS pod access via an IAM role. This approach satisfies the security requirement because Secrets Manager natively supports automated credential rotation for Amazon RDS, eliminating the need to store plaintext secrets, while an IAM role attached to the pod’s Kubernetes service account enables secure, temporary access without embedding credentials in the application code. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of the distinction between AWS Secrets Manager and AWS Systems Manager Parameter Store, as Parameter Store lacks built-in rotation capabilities—a common trap where candidates choose it for its lower cost. Another frequent mistake is selecting IAM database authentication, which uses short-lived tokens but does not rotate static credentials, making it unsuitable when the requirement explicitly calls for credential rotation. Memory tip: “Secrets rotate, tokens expire—know the difference for the SAP-C02.”
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 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?

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 can rotate RDS credentials automatically and provide them to applications via IAM roles. Option A (Parameter Store) does not support automatic rotation. Option B (environment variables) exposes credentials in plaintext. Option D (IAM database authentication) avoids passwords but does not rotate credentials; it uses tokens.
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.
✓
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.
Clue confirmation
The clue word "never" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
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.

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.

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.
