CCSP Cloud Data Security Practice Question
A cloud security engineer needs to protect a storage bucket from accidental deletion and ransomware attacks. Which two features should be enabled together for maximum protection?
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
✓
Bucket versioning and object lock
Versioning keeps multiple variants of an object, allowing recovery from accidental deletion or overwrite. Object lock (immutability) prevents objects from being deleted or overwritten for a specified retention period, protecting against ransomware. Combining both provides defense in depth.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
IAM policies and MFA delete
Why it's wrong here
IAM policies control who may call delete operations, and MFA delete requires a second factor for permanent deletion; together they address accidental deletion but not ransomware overwriting objects in place. They are correct when enforcing least privilege and deletion authorisation, not version recovery.
- ✓
Bucket versioning and object lock
Why this is correct
Bucket versioning preserves every object revision, so overwritten or deleted data remains recoverable, while object lock enforces WORM retention that blocks deletion even by compromised credentials. Together they satisfy the accidental-deletion and ransomware protection requirement, since neither alone prevents malicious overwrite.
- ✗
Cross-region replication and lifecycle policies
Why it's wrong here
Cross-region replication copies objects to another region and lifecycle policies transition or expire them; neither retains overwritten versions nor blocks deletion. They are correct when meeting durability or cost-management goals, not when recovering data after accidental deletion or ransomware.
- ✗
Server access logging and bucket policies
Why it's wrong here
Server access logging records requests and bucket policies grant or deny access; neither prevents deletion or provides version recovery. They are correct when auditing access patterns or enforcing authorisation rules, not when defending against accidental deletion or ransomware overwrite.
