The answer is denied, because the request uses HTTP and the Deny statement blocks it. This occurs because the SecureTransport condition in the Deny statement explicitly denies any S3 action on the confidential folder when the request is not sent over HTTPS, and in IAM policy evaluation, an explicit Deny always overrides any Allow. Even though the source IP falls within the allowed 10.0.0.0/24 range, the Deny for HTTP access takes precedence, making the request fail. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of IAM policy evaluation logic, particularly how SecureTransport interacts with both Allow and Deny statements—a common trap is assuming an Allow for IP will bypass a Deny for encryption. Remember the golden rule: explicit Deny wins every time, so always check for SecureTransport: false before assuming HTTPS is optional.
DOP-C02 Security and Compliance Practice Question
This DOP-C02 practice question tests your understanding of security and compliance. 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. An IAM policy is attached to a user. The user requests an object from the 'example-bucket' bucket, specifically from the 'confidential' folder, over HTTP (not HTTPS). The source IP is within the 10.0.0.0/24 range. What will be the result of this request?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Denied, because the request uses HTTP and the Deny statement blocks it.
The Deny statement with SecureTransport false applies to all s3 actions on the confidential folder. Even though the source IP is allowed, the Deny for HTTP access will override the Allow. The request will be denied.
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.
✗
Denied, because the user does not have s3:GetObject permission on the confidential folder.
Allowed, because the source IP is within the allowed range.
Why it's wrong here
The Deny statement overrides the Allow.
✓
Denied, because the request uses HTTP and the Deny statement blocks it.
Why this is correct
The Deny applies when SecureTransport is false (HTTP).
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 DOP-C02 ACL questions on filtering logic and placement.
