Correct answer & explanation
✓
Use EBS encryption with AWS KMS
Amazon EBS encryption with AWS KMS provides key management, rotation, and audit logging. S3 server-side encryption does not apply to EBS. AWS CloudHSM is for hardware-based key management but does not provide automatic key rotation. AWS Certificate Manager is for SSL/TLS certificates.
