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

runlevel 0: poweroff.target

Systemd targets align with traditional SysV runlevels: runlevel 0 → poweroff.target, runlevel 1 → rescue.target, runlevel 2/3/4 → multi-user.target, runlevel 5 → graphical.target, runlevel 6 → reboot.target. Common confusions involve mixing up GUI and non-GUI targets or confusing runlevels for shutdown/reboot.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • runlevel 0: poweroff.target

    Why this is correct

    Runlevel 0 halts the system, corresponding to poweroff.target in systemd.

  • runlevel 1: rescue.target

    Why this is correct

    Runlevel 1 is single-user mode, mapped to rescue.target.

  • runlevel 5: graphical.target

    Why this is correct

    Runlevel 5 is multi-user with GUI, corresponding to graphical.target.

  • runlevel 3: graphical.target

    Why it's wrong here

    Incorrect — runlevel 3 (multi-user without GUI) maps to multi-user.target, not graphical.target.

  • runlevel 6: rescue.target

    Why it's wrong here

    Incorrect — runlevel 6 reboots the system, corresponding to reboot.target, not rescue.target.

  • runlevel 2: poweroff.target

    Why it's wrong here

    Incorrect — runlevel 2 is multi-user without GUI (same as runlevel 3) and maps to multi-user.target, not poweroff.target.
