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 is not within the allowed IP range
The IAM policy includes a condition that restricts access to requests originating from the IP range 10.0.0.0/16 (a private range). The user's on-premises network has a public IP of 203.0.113.5, which is not within that range, so the condition fails and the upload is denied. Option A is incorrect because the resource ARN does include the bucket itself (arn:aws:s3:::my-bucket/*), so that is not the issue. Option C is incorrect because the policy explicitly allows s3:PutObject. Option D is incorrect because there is no condition requiring server-side encryption.
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 resource ARN does not include the bucket itself
Why it's wrong here
Object-level ARN is sufficient for object operations.
- ✓
The user's IP address is not within the allowed IP range
Why this is correct
The condition only allows 10.0.0.0/16.
- ✗
The user does not have s3:PutObject permission
Why it's wrong here
The policy includes s3:PutObject.
- ✗
The bucket requires server-side encryption
Why it's wrong here
No encryption condition in policy.
