CompTIA Linux+ XK0-006 (V8) Practice Question

After a confirmed breach, you must immediately stop the developer account named "dana" from logging in to a Red Hat-based server by any authentication method (password, SSH key, etc.). The account, its UID, and all running processes must stay intact so that you can restore access later with a single command. Which command satisfies these requirements?

  • usermod -L dana

  • chage -E 0 dana

  • usermod -s /usr/sbin/nologin dana

  • passwd -l dana
