Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Bucket versioning enabled
Why it's wrong here
Versioning helps with data recovery, not exposure.
- ✓
Bucket ACL set to public read
Why this is correct
Public read ACL allows anonymous access to all objects.
- ✗
Default encryption enabled
Why it's wrong here
Encryption protects data at rest, but public access bypasses it.
- ✗
Bucket policy with a condition for source IP
Why it's wrong here
This restricts access based on IP, reducing risk.
