Exam AWS Certified SysOps Administrator - Associate topic 1 question 209 discussion

  • B. Enable RDS encryption on the database at creation time by using the AWS managed key for Amazon RDS.
  • C. Create a new AWS Key Management Service (AWS KMS) customer managed key. Enable automatic key rotation. Enable RDS encryption on the database at creation time by using the KMS key.

B is easiest! Why would you choose C, a custom key with management overhead when you can just have AWS encrypt and rotate the key using default Encryption settings?

Selected Answer: C
Automatic key rotation is supported only on symmetric encryption KMS keys. You cannot enable automatic rotation of asymmetric KMS keys, HMAC KMS keys, KMS keys with imported key material, or KMS keys in a custom key store. To enable or disable automatic rotation of a set of related multi-Region keys, set the property on the primary key.
