This DVA-C02 practice question tests your understanding of security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Refer to the exhibit. A developer attached this bucket policy to an S3 bucket named 'my-bucket'. The IAM role 'AppRole' is used by an application running on EC2 instances with an IP address of 192.0.2.10. The application tries to upload an object to 'my-bucket/confidential/report.pdf'. Will the upload succeed?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Yes, because the Deny statement uses a condition that does not match the application's IP.
Option B is correct because the Deny statement explicitly denies all s3 actions on the 'confidential/' prefix unless the source IP is within 192.0.2.0/24. The application's IP is 192.0.2.10, which is within that range, so the condition is not met (the Deny does not apply). The Allow statement grants s3:PutObject on the bucket, so the upload succeeds. Option A is incorrect because the Deny does not apply. Option C is incorrect because the Allow does apply. Option D is incorrect because the condition is met (IP is within range).
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.
✗
Yes, but only if the application also has an IAM policy that allows s3:PutObject.
Why it's wrong here
The bucket policy grants the permission directly to the role; additional IAM policy is not required (though not harmful).
✗
No, because the Deny statement denies all s3 actions on the 'confidential/' prefix.
Why it's wrong here
The Deny has a condition that does not apply because the IP is in the allowed range.
✗
No, because the Allow statement only allows GetObject and PutObject on the entire bucket, but the Deny overrides.
Why it's wrong here
The Deny does not apply, so Allow is effective.
✓
Yes, because the Deny statement uses a condition that does not match the application's IP.
Why this is correct
The Deny applies only if the IP is NOT in 192.0.2.0/24; the IP is in that range, so Deny is not triggered.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
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 DVA-C02 ACL questions on filtering logic and placement.

What is the correct answer to this question?
The correct answer is: Yes, because the Deny statement uses a condition that does not match the application's IP. — Option B is correct because the Deny statement explicitly denies all s3 actions on the 'confidential/' prefix unless the source IP is within 192.0.2.0/24. The application's IP is 192.0.2.10, which is within that range, so the condition is not met (the Deny does not apply). The Allow statement grants s3:PutObject on the bucket, so the upload succeeds. Option A is incorrect because the Deny does not apply. Option C is incorrect because the Allow does apply. Option D is incorrect because the condition is met (IP is within range).
