Same concept, more angles
1 more way this is tested on DBS-C01
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. A company needs to securely store and manage the master password for their Amazon RDS for PostgreSQL instance. Which AWS service is purpose-built for managing secrets with automatic rotation?
easy- A.AWS Key Management Service (KMS)
- ✓ B.AWS Secrets Manager
- C.AWS Identity and Access Management (IAM)
- D.AWS CloudHSM
Why B: AWS Secrets Manager is designed for secret management with built-in rotation. Option A is wrong because KMS is for encryption keys, not secret management. Option C is wrong because IAM is for identity and access management, not secret storage. Option D is wrong because CloudHSM provides hardware security modules but not secret rotation.
