The correct answer is that only requests using HTTPS from the IP range 192.0.2.0/24 are allowed. This is because the S3 bucket policy includes an explicit Deny for non-SecureTransport, which overrides any Allow statements, effectively blocking all HTTP requests regardless of source IP. The Allow statement for the specified IP range is then narrowed by the Deny, meaning only HTTPS traffic from that range is permitted. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of how explicit Deny in an S3 bucket policy interacts with Allow statements, a common trap where candidates forget that Deny always wins. A key memory tip is "Deny beats Allow, and condition keys like SecureTransport act as a filter on the Deny itself."
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Only requests using HTTPS from the IP range 192.0.2.0/24 are allowed.
Option D is correct because the Deny for non-SecureTransport overrides the Allow, so only HTTPS requests from the specified IP range are allowed. Option A is wrong because non-HTTPS requests are denied. Option B is wrong because requests from outside the IP range are denied. Option C is wrong because the Deny is explicit.
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.
✗
All HTTPS requests from any IP are allowed.
Why it's wrong here
HTTPS requests from outside the IP range are denied by the first statement's condition.
✗
Only requests using HTTPS from any IP are allowed because the Deny is overridden.
Why it's wrong here
The Deny is explicit and overrides Allow.
✓
Only requests using HTTPS from the IP range 192.0.2.0/24 are allowed.
Why this is correct
The Allow requires the IP, and the Deny blocks non-HTTPS.
Related concept
Standard ACLs match source addresses.
✗
All requests from the IP range 192.0.2.0/24 are allowed, regardless of protocol.
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 SAP-C02 ACL questions on filtering logic and placement.

What is the correct answer to this question?
The correct answer is: Only requests using HTTPS from the IP range 192.0.2.0/24 are allowed. — Option D is correct because the Deny for non-SecureTransport overrides the Allow, so only HTTPS requests from the specified IP range are allowed. Option A is wrong because non-HTTPS requests are denied. Option B is wrong because requests from outside the IP range are denied. Option C is wrong because the Deny is explicit.
