- A
Cloud VPN connection for the auditor
Why wrong: VPN provides network access but not object-level, time-limited access.
- B
Bucket ACL granting read access to the auditor's cloud account
Why wrong: ACLs are permanent and not time-limited; they also require the auditor to have a cloud account.
- C
IAM policy granting read access to the auditor's user
Why wrong: IAM grants persistent access; also requires auditor to have an IAM user in the cloud account.
- D
Pre-signed URL with an expiration time
Pre-signed URLs provide time-limited, object-specific access without requiring the user to have cloud credentials.

CCSP Cloud Data Security Practice Question
This CCSP practice question tests your understanding of cloud data security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 architect is designing a multi-cloud data protection strategy. They need to give a third-party auditor time-limited, read-only access to a specific file in a cloud storage bucket. Which access control method is most appropriate?
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
✓
Pre-signed URL with an expiration time
Pre-signed URLs (or signed URLs) grant temporary access to a specific object without requiring the auditor to have cloud credentials. They can be configured with expiration times and permissions (e.g., read-only).
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cloud VPN connection for the auditor
Why it's wrong here
VPN provides network access but not object-level, time-limited access.
- ✗
Bucket ACL granting read access to the auditor's cloud account
Why it's wrong here
ACLs are permanent and not time-limited; they also require the auditor to have a cloud account.
- ✗
IAM policy granting read access to the auditor's user
Why it's wrong here
IAM grants persistent access; also requires auditor to have an IAM user in the cloud account.
- ✓
Pre-signed URL with an expiration time
Why this is correct
Pre-signed URLs provide time-limited, object-specific access without requiring the user to have cloud credentials.
Related concept
Standard ACLs match source addresses.
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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. 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. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
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.
