- A
Bucket versioning
Versioning protects against accidental deletion or overwrites.
- B
Bucket ACL restricting write access
Why wrong: ACLs restrict access but can be changed; object lock enforces immutability.
- C
Lifecycle policy to transition to archival storage
Why wrong: Lifecycle policies move data but do not prevent modification or deletion.
- D
Object lock with retention period
Object lock prevents object modification or deletion during the retention period.
- E
Cross-region replication
Why wrong: Replication does not prevent modification or deletion.

CCSP Cloud Data Security Practice Question
This CCSP practice question tests your understanding of cloud data security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security analyst is reviewing a cloud storage bucket that contains archived customer records. The analyst wants to ensure that no object in the bucket can be modified or deleted for 7 years to meet regulatory retention requirements. Which TWO features should be enabled? (Select 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
✓
Bucket versioning
Object lock (retention mode) enforces a retention period on objects, preventing deletion or modification. Versioning allows recovery in case of accidental deletion of lock or creation of delete markers. Together they provide a comprehensive retention solution, though object lock alone may suffice if versioning is not required.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related CCSP ACL questions on filtering logic and placement.
