CCSP Cloud Data Security Practice Question
A company uses a cloud key management service with customer-managed keys to encrypt data in a cloud storage bucket. The security team wants to ensure that if a key is compromised, they can revoke the cloud service's ability to decrypt the data immediately. What should they do?
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
✓
Disable the key in the cloud key management service or revoke the key's access permissions for the cloud service.
With customer-managed keys, the customer controls the key and can revoke the cloud service's access by disabling the key or removing the access permission that allows the service to use the key. Deleting the key would also work but is irreversible. Disabling the key is reversible and immediate.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rotate the key to a new version.
Why it's wrong here
Rotation does not revoke access to the old key.
- ✗
Delete the key permanently from the cloud key management service.
Why it's wrong here
Deletion is irreversible and may not be immediate due to waiting periods.
- ✗
Regenerate the key material by importing a new key.
Why it's wrong here
Importing a new key does not revoke access to the existing key.
- ✓
Disable the key in the cloud key management service or revoke the key's access permissions for the cloud service.
Why this is correct
Disabling the key or revoking permissions immediately prevents the service from decrypting data.
