Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

All API calls that are not made over HTTPS will be denied

The SCP uses a Deny effect with a condition that blocks all API calls when the request is not made over HTTPS (i.e., aws:SecureTransport is false). This effectively denies any API call that uses HTTP instead of HTTPS. Option A is incorrect because the policy denies non-HTTPS calls, not allows them. Option B is incorrect because the policy applies to all AWS services, not just S3. Option C is incorrect because the condition checks for transport security, not multi-factor authentication. Option D correctly states that all API calls not made over HTTPS will be denied.

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 API calls over HTTPS will be allowed
Why it's wrong here
The policy denies non-HTTPS; it does not explicitly allow anything.
✗
Only S3 API calls will be affected
Why it's wrong here
The policy applies to all actions ("*").
✗
The policy requires multi-factor authentication
Why it's wrong here
There is no condition for MFA.
✓
All API calls that are not made over HTTPS will be denied
Why this is correct
The condition aws:SecureTransport false triggers a Deny on all actions.
