SCS-C02 Management and Security Governance Practice Question
This SCS-C02 practice question tests your understanding of management and security governance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 reports that they cannot upload files to the S3 bucket 'example-bucket' using the AWS CLI with HTTPS. What is the most likely reason?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user does not have an explicit allow for s3:PutObject.
Option B is correct because the policy denies s3:* actions on objects in the bucket when SecureTransport is false, meaning it denies only HTTP requests. However, the user is using HTTPS, so the deny should not apply. But the policy also implicitly denies all other actions not explicitly allowed? Actually, an explicit deny overrides any allow, but the condition only denies when SecureTransport is false. Since the user uses HTTPS, the condition is not met, so the deny does not apply. But the user might have no allow for s3:PutObject, which is the issue. Option B is correct because there is no explicit allow for s3:PutObject, and the default implicit deny applies. Option A is wrong because the condition does not apply. Option C is wrong because the AccessDenied error indicates permissions, not bucket name. Option D is wrong because the error is not about encryption.
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 requires server-side encryption and the user did not specify it.
Why it's wrong here
There is no indication of encryption requirement.
✗
The policy denies all S3 actions when using HTTPS.
Why it's wrong here
The deny only applies when SecureTransport is false, so HTTPS is not denied.
✓
The user does not have an explicit allow for s3:PutObject.
Why this is correct
The policy only denies; without an allow, the default deny blocks the upload.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
✗
The bucket name is incorrect in the policy.
Why it's wrong here
The bucket name is correct; the error is permissions-related.
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 SCS-C02 ACL questions on filtering logic and placement.

What is the correct answer to this question?
The correct answer is: The user does not have an explicit allow for s3:PutObject. — Option B is correct because the policy denies s3:* actions on objects in the bucket when SecureTransport is false, meaning it denies only HTTP requests. However, the user is using HTTPS, so the deny should not apply. But the policy also implicitly denies all other actions not explicitly allowed? Actually, an explicit deny overrides any allow, but the condition only denies when SecureTransport is false. Since the user uses HTTPS, the condition is not met, so the deny does not apply. But the user might have no allow for s3:PutObject, which is the issue. Option B is correct because there is no explicit allow for s3:PutObject, and the default implicit deny applies. Option A is wrong because the condition does not apply. Option C is wrong because the AccessDenied error indicates permissions, not bucket name. Option D is wrong because the error is not about encryption.
What should I do if I get this SCS-C02 question wrong?

Are there clue words in this question I should notice?
Yes — watch for: "most likely". Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
