This CCSP practice question tests your understanding of cloud security operations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 notices that a cloud storage bucket contains objects with public read access. The organization's policy prohibits public access. What is the most efficient way to remediate this issue across all objects in the bucket?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply a bucket policy that denies public access and update the bucket ACL to block public access
Option B is correct because applying a bucket policy that denies public access and updating the bucket ACL to block public access will override any object-level public ACLs. Option A is inefficient as it requires manual object updates. Option C is unnecessarily disruptive. Option D may not be needed.
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.
✗
Delete the bucket and recreate it
Why it's wrong here
Deleting the bucket is overly destructive and unnecessary.
✗
Use a third-party tool to scan and fix
Why it's wrong here
Third-party tools are not always efficient and may introduce extra complexity.
✓
Apply a bucket policy that denies public access and update the bucket ACL to block public access
Why this is correct
Bucket-level policies and ACLs override object-level permissions, efficiently blocking public access.
Related concept
Standard ACLs match source addresses.
✗
Manually update each object's ACL
Why it's wrong here
Manual updates are time-consuming and error-prone; not efficient for many objects.
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 team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
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.
