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 user's IP address does not match the condition in the policy.
The policy includes a condition that allows s3:GetObject only if the request originates from the 10.0.0.0/16 IP range. The user's IP address 10.1.1.1 falls outside this range, so the condition is not satisfied, resulting in an implicit deny. Therefore, the most likely reason for the denial is that the user's IP address does not match the condition, making option D correct. Option A is incorrect because the policy does allow s3:GetObject. Option B is incorrect because the policy has no syntax error. Option C is incorrect because there is no explicit deny statement.
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 allow the s3:GetObject action.
Why it's wrong here
The policy explicitly allows s3:GetObject.
- ✗
The policy has a syntax error.
Why it's wrong here
The policy syntax is correct.
- ✗
There is an explicit deny statement elsewhere that overrides the allow.
Why it's wrong here
No explicit deny is shown.
- ✓
The user's IP address does not match the condition in the policy.
Why this is correct
The condition restricts access to IP range 10.0.0.0/16; 10.1.1.1 is outside.
