Service-managed vs customer-managed vs BYOK keys
WHAT IT TESTS: key management control versus burden. OUTLINE: service-managed keys are automatic but opaque; CMK gives you control over rotation, policy, and revocation in a KMS; BYOK imports your own key material for compliance.
WHAT IT TESTS: understanding the control-versus-operational-burden spectrum of encryption keys. ANSWER OUTLINE: service-managed keys are created and rotated by the provider with zero effort but no visibility or independent revocation. Customer-managed keys live in a KMS you control, letting you set rotation, access policy, and audit, and revoke to disable data access, at the cost of managing them. BYOK imports your own externally generated key material for compliance and provenance, adding the most operational responsibility.
