Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
jdoe ALL=(ALL) NOPASSWD: ALL
Why it's wrong here
This bypasses password prompt, which is not desired.
- ✗
jdoe ALL=(root) /usr/bin/su
Why it's wrong here
This only allows jdoe to run su as root, not any command.
- ✗
jdoe ALL= /bin/su -
Why it's wrong here
Syntax is incorrect; missing (runas) and too restrictive.
- ✓
jdoe ALL=(ALL) ALL
Why this is correct
This allows jdoe to run any command as any user, but requires a password by default.
