LPIC-1 System Architecture Practice Question
Exhibit
Refer to the exhibit. ``` UNIT LOAD ACTIVE SUB DESCRIPTION basic.target loaded active active Basic System cryptsetup.target loaded active active Local Encrypted Volumes getty.target loaded active active Login Prompts graphical.target loaded active active Graphical Interface local-fs-pre.target loaded active active Local File Systems (Pre) local-fs.target loaded active active Local File Systems multi-user.target loaded active active Multi-User System network-online.target loaded active active Network is Online network.target loaded active active Network paths.target loaded active active Paths remote-fs.target loaded active active Remote File Systems slices.target loaded active active Slices sockets.target loaded active active Sockets swap.target loaded active active Swap sysinit.target loaded active active System Initialization timers.target loaded active active Timers ```
A system administrator notices that the system boots to the graphical interface but wants to change it to boot to a non-graphical multi-user target. Which command will make this change persistent?
⚠ Common exam trap
Candidates often confuse `isolate` (which changes the current target but is not persistent) with `set-default` (which makes the change permanent), leading them to incorrectly select Option B.

Correct answer & explanation
✓
systemctl set-default multi-user.target
`systemctl set-default multi-user.target` changes the default systemd target to `multi-user.target`, which boots to a non-graphical multi-user environment. This change is persistent across reboots, as it updates the symlink `/etc/systemd/system/default.target` to point to `multi-user.target`.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
systemctl set-default multi-user.target
Why this is correct
Sets the default target persistently.
- ✗
systemctl isolate multi-user.target
Why it's wrong here
Switches to multi-user now but does not change default.
- ✗
systemctl enable multi-user.target
Why it's wrong here
Enable is not the correct verb for targets; set-default is used.
- ✗
systemctl start multi-user.target
Why it's wrong here
Starts the target but does not set it as default.
