LFCS Service Configuration Practice Question
Which two commands produce output that includes the current runlevel or target? (Choose two.)
⚠ Common exam trap
The trap here is that candidates often pick `systemctl get-default` (option E) thinking it shows the current target, but it only shows the default target for the next boot, not the currently active target, which is a common confusion between persistent default and runtime state.

Correct answer & explanation
✓
runlevel
The `runlevel` command displays the previous and current runlevel from the `/var/run/utmp` file, making it a direct way to see the current runlevel. The `who -r` command reads the same utmp file and prints the current runlevel along with the time of the last runlevel change, so both commands produce output that includes the current runlevel or target.
