The answer is the Deny statement blocks all S3 actions when the request is not using HTTPS. This is because the bucket policy explicitly denies all s3:* actions when the condition key aws:SecureTransport is set to false, meaning the request is made over HTTP. Even though a subsequent statement allows s3:GetObject to everyone, AWS IAM policy evaluation rules dictate that an explicit Deny always overrides any Allow. This question tests your understanding of S3 bucket policy evaluation logic and the SecureTransport condition key, a common topic on the AWS Certified SysOps Administrator Associate SOA-C02 exam. A frequent trap is assuming that an Allow statement will override a Deny, or misreading the Deny as applying only to PutObject. Remember the golden rule: an explicit Deny is the final word—it cannot be overridden by any Allow. Memory tip: "Deny is the final say, no matter what the Allow may say."
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.
A company has the following S3 bucket policy attached to a bucket named 'example-bucket'. A user is unable to download an object from the bucket using an HTTP URL (not HTTPS). What is the cause?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Deny statement blocks all S3 actions when the request is not using HTTPS.
Option C is correct because the first statement denies all s3:* actions when SecureTransport is false (i.e., HTTP). The second statement allows GetObject to everyone, but the Deny statement takes precedence. Option A is wrong because the bucket policy does not require SSE. Option B is wrong because the policy allows GetObject to everyone. Option D is wrong because the Deny is for all s3 actions, not just PutObject.
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.
✗
The bucket policy does not allow GetObject for anonymous users.
Why it's wrong here
The Allow statement grants GetObject to everyone.
✓
The Deny statement blocks all S3 actions when the request is not using HTTPS.
Why this is correct
Deny overrides Allow when condition is met.
Related concept
Standard ACLs match source addresses.
✗
The bucket policy requires server-side encryption for all requests.
Why it's wrong here
No encryption condition is present.
✗
The Deny statement only applies to PutObject, not GetObject.
Why it's wrong here
Deny applies to all s3:* actions.
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.
