CCSP Cloud Data Security Practice Question
A company uses a cloud key management service (KMS) with an HSM-backed key for encrypting sensitive data. They want to ensure that the key is automatically rotated every 90 days and that older key versions are retained for decryption of previously encrypted data. Which KMS feature should be configured?

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
✓
Automatic key rotation with version retention
Key rotation in cloud KMS (e.g., AWS KMS, Azure Key Vault, GCP Cloud KMS) can be set to automatic rotation with a specified period. Old key versions are retained so that data encrypted with older keys can still be decrypted. The key material changes, but key ID remains the same.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Automatic key rotation with version retention
Why this is correct
Automatic rotation creates new key versions; old versions are retained for decryption.
- ✗
Key aliasing
Why it's wrong here
Aliases are alternate names for keys, not rotation.
- ✗
Key destruction schedule
Why it's wrong here
Destruction is the opposite of retention; it removes keys.
- ✗
Key revocation policy
Why it's wrong here
Revocation disables the key, not rotates it.
