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
✓
Hold Your Own Key (HYOK)
BYOK allows generating keys on-premises and importing them into cloud KMS. HYOK keeps keys on-premises and cloud services call back to the on-premises HSM for operations. Both involve keys originating on-premises.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Customer-Managed Encryption Key (CMEK)
Why it's wrong here
CMEK keys are generated in the cloud KMS, not on-premises.

Cloud provider default encryption
Why it's wrong here
Cloud provider default uses provider-managed keys, not customer on-premises.
- ✓
Hold Your Own Key (HYOK)
Why this is correct
HYOK keeps keys on-premises and cloud services use them remotely.
- ✓
Bring Your Own Key (BYOK)
Why this is correct
BYOK generates keys on-premises and imports them to cloud KMS.
