This CCSP practice question tests your understanding of cloud security operations. 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 analyst is using a cloud security posture management (CSPM) tool that reports a finding of "storage bucket publicly accessible." However, upon manual inspection, the bucket's ACL and bucket policy both restrict access to authorized users only. What is the most likely cause of the false positive?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The bucket contains objects with public ACLs
Option D is correct because individual objects within the bucket might have public ACLs, which CSPM might detect. Option A (CSPM misconfigured) is possible but less likely. Option B (policy syntax error) would cause error, not public access. Option C (region mismatch) is irrelevant.
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.
✗
The bucket is in a different region
Why it's wrong here
Region does not affect access permissions.
✗
The bucket policy has a syntax error
Why it's wrong here
A syntax error would likely cause a different error, not a false positive.
✓
The bucket contains objects with public ACLs
Why this is correct
Object-level ACLs can override bucket-level settings and cause a public access finding.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
✗
The CSPM tool is misconfigured
Why it's wrong here
Misconfiguration is possible but not the most likely cause.
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.

The correct answer is: The bucket contains objects with public ACLs — Option D is correct because individual objects within the bucket might have public ACLs, which CSPM might detect. Option A (CSPM misconfigured) is possible but less likely. Option B (policy syntax error) would cause error, not public access. Option C (region mismatch) is irrelevant.
