```An IAM policy attached to an S3 bucket is shown. What is the net effect on requests to read objects from the bucket?
⚠ Common exam trap
Candidates often assume an Allow statement alone grants access, forgetting that an explicit Deny with conditions can restrict that Allow, leading them to overlook the combined effect of the Deny's conditions on both protocol and IP range.
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
✓
Only requests using HTTPS from the IP range 192.0.2.0/24 are allowed.
The IAM policy includes a Deny statement that blocks all requests unless they use HTTPS and originate from the 192.0.2.0/24 IP range. The Allow statement grants read access to the bucket, but the Deny with a condition (aws:SecureTransport and aws:SourceIp) explicitly overrides the Allow for requests that do not meet both conditions. Therefore, only HTTPS requests from the specified IP range are permitted, making option C correct.
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 HTTPS requests from any IP are allowed.
Why it's wrong here
HTTPS requests from outside the IP range are denied by the first statement's condition.
- ✗
Only requests using HTTPS from any IP are allowed because the Deny is overridden.
Why it's wrong here
The Deny is explicit and overrides Allow.
- ✓
Only requests using HTTPS from the IP range 192.0.2.0/24 are allowed.
Why this is correct
The Allow requires the IP, and the Deny blocks non-HTTPS.
- ✗
All requests from the IP range 192.0.2.0/24 are allowed, regardless of protocol.
Why it's wrong here
Non-HTTPS requests from that range are denied.
