Correct answer & explanation
✓
Specify a customer managed KMS key when enabling encryption
Amazon Redshift supports encryption at rest using AWS KMS. To use a key managed by the company (customer managed key), you must specify a customer managed KMS key when enabling encryption. Option D is correct. Option A uses an AWS managed key (default), which is not managed by the company. Option B refers to encryption in transit, not at rest. Option C: HSM is not directly supported for Redshift encryption; KMS is used.
