CCSP Practice Question: Uses cloud object storage for backup data and…
An organization uses cloud object storage for backup data and requires that once written, data cannot be modified or deleted for a specified retention period. Which feature should they enable?
⚠ Common exam trap
ISC2 often tests the misconception that bucket versioning alone provides data immutability, but versioning only protects against accidental overwrites by preserving old versions, not against intentional deletion or modification of the current version.

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
✓
Object lock with write-once-read-many (WORM) protection
Object lock with WORM protection is the correct feature because it enforces a retention policy that prevents any user, including the root account, from modifying or deleting objects until the retention period expires. This is specifically designed for compliance requirements such as SEC 17a-4(f) and ensures data immutability at the object level, which bucket versioning, encryption, or lifecycle rules cannot guarantee.
