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 Key Management Service (KMS)
Amazon Redshift uses AWS KMS for encryption at rest. You can use either the default AWS-managed key or a customer-managed CMK. KMS integrates with Redshift to encrypt data in the cluster and allows fine-grained control over key access via IAM policies. CloudHSM is not directly integrated with Redshift. Secrets Manager and Systems Manager Parameter Store are for secrets, not encryption keys for Redshift.
