The correct answer is that the policy allows all HTTPS requests and denies HTTP requests. This works because the condition block uses `aws:SecureTransport` set to `false` to explicitly deny any S3 action on objects (noted by the `bucket/*` resource) when the request is not using HTTPS, while no explicit allow statement is needed since S3 bucket policies default to allowing access unless a matching deny is present. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your understanding of how S3 bucket policies enforce encryption in transit, a common security requirement for compliance. A frequent trap is assuming that a deny on HTTP automatically blocks HTTPS, but the deny only triggers when `SecureTransport` is false, leaving HTTPS unaffected. For a quick memory tip, think “Deny false, allow safe”—if secure transport is false, the request is denied; otherwise, it’s allowed by default.
SOA-C02 Security and Compliance Practice Question
This SOA-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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Allows all HTTPS requests and denies HTTP requests.
Option C is correct because the policy Denies all S3 actions on objects if the request is not using HTTPS (secure transport false). Requests over HTTP are denied. Option A is wrong because the policy allows HTTPS requests (no allow statement needed; default allow if no explicit deny). Option B is wrong because the policy only denies if SecureTransport is false, not always. Option D is wrong because the policy does not affect bucket-level operations (note the resource is bucket/*).
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.
Denies access to the bucket from any IP other than the VPC.
Why it's wrong here
No IP condition in the policy.
✓
Allows all HTTPS requests and denies HTTP requests.
Why this is correct
The policy denies HTTP, and HTTPS is implicitly allowed.
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 SOA-C02 ACL questions on filtering logic and placement.
