CCSP Cloud Data Security Practice Question
A cloud security team needs to ensure that all data in transit between on-premises systems and the cloud is encrypted. Which TWO options should they consider? (Choose two.)
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
✓
Set up a VPN between on-premises and cloud
TLS 1.2+ encrypts API communications, and VPN establishes an encrypted tunnel for hybrid connectivity. Both protect data in transit.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set up a VPN between on-premises and cloud
Why this is correct
VPN encrypts all traffic between networks.
- ✗
Use signed URLs for access
Why it's wrong here
Signed URLs provide authentication, not encryption in transit.
- ✗
Enable bucket versioning
Why it's wrong here
Versioning protects data at rest, not in transit.
- ✗
Enable server-side encryption with CMEK
Why it's wrong here
Server-side encryption with CMEK protects data at rest within the cloud storage layer, not data in transit across the network boundary between on-premises systems and the cloud. It is tempting because CMEK gives the customer control over the encryption key lifecycle, which is often mandated for compliance; however, it would be the correct choice for a scenario requiring the organisation to manage its own keys for encrypting stored objects, such as a regulatory requirement for key rotation or revocation.
- ✓
Use TLS 1.2+ for all API calls
Why this is correct
TLS encrypts data in transit.
