CCSP Cloud Data Security Practice Question
A healthcare organization is storing patient records in a cloud object storage service. They must encrypt data at rest with keys they control and rotate regularly, but they do not want to manage the encryption process themselves. Which encryption option should they use?
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)
CMEK allows the customer to create and manage keys in the cloud KMS, while the cloud service performs encryption/decryption using those keys, providing control without operational burden.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Server-side encryption with cloud provider default keys
Why it's wrong here
Default keys are managed by the provider, not the customer.
- ✓
Customer-managed encryption keys (CMEK)
Why this is correct
Correct: customer creates keys in KMS, authorizes cloud service, and retains control.
- ✗
Customer-supplied encryption keys (CSEK)
Why it's wrong here
CSEK requires the customer to supply the key with each API call, not ideal for automatic rotation.
- ✗
Client-side encryption
Why it's wrong here
Client-side encryption is performed before upload, requiring customer to manage keys entirely.
