XK0-006 Practice Question: Allow a user to run all commands as root without…

An administrator needs to allow a user to run all commands as root without a password. Which sudoers entry accomplishes this?

⚠ Common exam trap

Many candidates confuse the default behavior of `ALL` (which still requires a password) with the `NOPASSWD` tag, leading them to select option D thinking it allows passwordless execution.

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

✓

user ALL=(ALL) NOPASSWD: ALL

The sudoers entry `user ALL=(ALL) NOPASSWD: ALL` grants the user permission to run any command as any user (including root) without being prompted for a password. The `NOPASSWD` tag overrides the default password requirement, and the `ALL` specifications cover the host list, target user list, and command list.
