CompTIA Linux+ XK0-006 (V8) Practice Question

During a security audit you discover that the legacy telnet.socket unit is still present on a systemd-based server. Policy requires that the socket be stopped immediately and rendered unstartable-whether manually or as a dependency-until administrators explicitly re-enable it at a later date. Which single systemctl command fulfills this requirement and ensures the state persists across reboots?

  • systemctl disable --now telnet.socket

  • systemctl disable --force telnet.socket

  • systemctl mask --now telnet.socket

  • systemctl stop telnet.socket && systemctl disable telnet.socket
