Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
usermod -aG developers
Why it's wrong here
This adds a user to a group, which does not automate inheritance.
- ✗
chgrp developers /data
Why it's wrong here
This changes existing group ownership, not inheritance for new files.
- ✓
chmod g+s /data
Why this is correct
The setgid bit on a directory forces group inheritance.
- ✗
chmod 1777 /data
Why it's wrong here
This sets the sticky bit, used to prevent file deletion by others.
