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
✓
Customer-managed encryption keys (CMEK)
Customer-managed encryption keys (CMEK) allow the customer to create and manage keys in cloud KMS, enabling automatic rotation and fine-grained access policies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cloud provider default encryption
Why it's wrong here
Default encryption uses provider-managed keys; the customer cannot control rotation or policies.
- ✓
Customer-managed encryption keys (CMEK)
Why this is correct
CMEK allows customers to manage keys in KMS, including rotation and access policies.
- ✗
Customer-supplied encryption keys (CSEK)
Why it's wrong here
CSEK requires the customer to supply keys with each request; rotation is not automated via KMS.
- ✗
Bring your own key (BYOK)
Why it's wrong here
BYOK involves importing keys from on-premises; rotation is managed by the customer but not necessarily automated via cloud KMS.
