- A
Bucket versioning enabled
Why wrong: Versioning helps with data recovery, not exposure.
- B
Bucket ACL set to public read
Public read ACL allows anonymous access to all objects.
- C
Default encryption enabled
Why wrong: Encryption protects data at rest, but public access bypasses it.
- D
Bucket policy with a condition for source IP
Why wrong: This restricts access based on IP, reducing risk.

CCSP Cloud Application Security Practice Question
This CCSP practice question tests your understanding of cloud application 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 cloud-native application stores sensitive user files in an Amazon S3 bucket. Which misconfiguration poses the greatest risk of data exposure?
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 ACL set to public read
Setting the S3 bucket ACL to public read allows anyone on the internet to access files, leading to data exposure.
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.

- ✗
Bucket versioning enabled
Why it's wrong here
Versioning helps with data recovery, not exposure.
- ✓
Bucket ACL set to public read
Why this is correct
Public read ACL allows anonymous access to all objects.
Related concept
Standard ACLs match source addresses.
- ✗
Default encryption enabled
Why it's wrong here
Encryption protects data at rest, but public access bypasses it.
- ✗
Bucket policy with a condition for source IP
Why it's wrong here
This restricts access based on IP, reducing risk.
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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
