}Refer to the exhibit. A cloud security analyst is reviewing an S3 bucket policy. The bucket contains sensitive data and must only be accessible over HTTPS from the internal network (10.0.0.0/24). Which of the following correctly describes the behavior of this policy?
⚠ Common exam trap
ISC2 often tests the misconception that an Allow statement alone is sufficient to grant access, ignoring that an explicit Deny with broader conditions can override it, or that a policy with both Allow and Deny is automatically invalid.
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
✓
Requests from 10.0.0.0/24 over HTTPS are allowed; all other requests are denied.
The policy uses an explicit Deny for any request that is not using HTTPS (i.e., aws:SecureTransport is false) or does not originate from the 10.0.0.0/24 IP range. This Deny overrides the Allow statement, ensuring that only requests meeting both conditions (source IP 10.0.0.0/24 AND HTTPS) are permitted. Requests from 10.0.0.0/24 over HTTPS satisfy the Allow and are not caught by the Deny, so they are allowed; all other requests are 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.
- ✓
Requests from 10.0.0.0/24 over HTTPS are allowed; all other requests are denied.
Why this is correct
The Allow statement permits GetObject from the internal IP range, and the Deny blocks non-HTTPS requests. Requests from external IPs are implicitly denied.
- ✗
Requests from 10.0.0.0/24 over HTTP are allowed because the Allow statement matches.
Why it's wrong here
The Deny statement explicitly denies non-HTTPS requests, overriding the Allow.
- ✗
The policy is invalid because it combines Allow and Deny statements.
Why it's wrong here
Combining Allow and Deny statements is valid; explicit deny overrides allow.
- ✗
All requests from 10.0.0.0/24 are denied because the Deny statement applies to all actions.
Why it's wrong here
The Deny only applies when SecureTransport is false; HTTPS requests are not denied.
