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
✓
AWS Secrets Manager
AWS Secrets Manager is the correct service because it can automatically rotate database credentials for Amazon RDS, simplifying credential management and improving security. AWS Systems Manager Parameter Store can store parameters but does not natively rotate RDS credentials. AWS IAM roles are used for authentication and authorization, not for storing credentials. AWS CloudHSM provides hardware security module (HSM) for encryption key management, not credential storage or rotation.
