Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add world read permission.
Why it's wrong here
This would violate the policy by allowing others to read the file.
- ✗
Change group permissions to rw-r--.
Why it's wrong here
This would give group write permission, which is not needed and violates least privilege.
- ✓
Change the file mode to 640.
Why this is correct
640 (rw-r-----) removes the execute permission that is not required for read-only access, adhering to least privilege.
- ✗
Change the owner to user2.
Why it's wrong here
Changing owner does not address the group's unnecessary execute permission.
