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
✓
It allows anyone to read objects in example-bucket only if they come from the specified IP range.
The policy allows s3:GetObject to any principal (*) but only if the request originates from the IP range 203.0.113.0/24. This is a common way to restrict access to a specific network. It does not deny other IPs explicitly; it just doesn't allow them. It does not require authentication; the principal is *.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It requires users to authenticate with AWS IAM before accessing the bucket.
Why it's wrong here
The principal is *, meaning no authentication is required; it's a public policy with IP restriction.
- ✓
It allows anyone to read objects in example-bucket only if they come from the specified IP range.
Why this is correct
The effect is Allow, principal is *, action is GetObject, and condition restricts by source IP.
- ✗
It allows only the specified IP range to write objects.
Why it's wrong here
The action is GetObject (read), not PutObject (write).
- ✗
It denies all access to the bucket except from the specified IP range.
Why it's wrong here
The policy is an Allow, not a Deny. To explicitly deny, you would need a Deny statement.
