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
✓
The policy allows any AWS user to read objects if they are within the specified IP range.
The policy allows any AWS user (Principal: "*") to read objects if they are from the specified IP range. This is overly permissive, granting access to the entire internet at that range, which could include malicious actors. The condition is correctly applied (B is false), encryption is not the main issue (C), and NotPrincipal is not required (D).
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 policy does not require encryption in transit, so data could be intercepted.
Why it's wrong here
While encryption in transit is important, the most significant risk is the broad access granted; lack of encryption is a separate concern.
- ✗
The Condition block is misconfigured and will allow access from any IP address.
Why it's wrong here
The condition is correctly written and will restrict access to the specified IP range.
- ✓
The policy allows any AWS user to read objects if they are within the specified IP range.
Why this is correct
This is correct; the combination of Principal: '*' and IP condition means anyone from that IP range can access the data, which is a significant risk if the range includes untrusted networks.
- ✗
The policy does not include a NotPrincipal element to restrict access further.
Why it's wrong here
NotPrincipal is not necessary for this policy; the main issue is the permissive Principal.
