CompTIA Linux+ XK0-006 (V8) Practice Question

While troubleshooting an SSH session that uses X11 forwarding you run echo $DISPLAY on the remote host and the shell returns localhost:10.0.

What does the number 10 in this value indicate?

  • It is the virtual console (tty) that will receive keyboard input from the remote program.

  • It represents the screen number of a multi-monitor setup, meaning screen 10 of display 0 on the workstation.

  • It is the display number dynamically assigned by sshd for the forwarded X session, so X clients will connect to TCP port 6010 on localhost.

  • It is the numeric identifier of the MIT-MAGIC-COOKIE-1 entry created by xauth for this SSH session.
