LFCS Service Configuration Practice Question
Which command displays the current status of all active services?
⚠ Common exam trap
Many exam-takers confuse `systemctl status --all` (which shows all units regardless of state) with listing only active services, or they mistakenly think `systemctl list-unit-files` shows current runtime status instead of disk-based enablement configuration.

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
✓
systemctl list-units --type=service --state=active
`systemctl list-units --type=service --state=active` filters systemd units to show only those of type 'service' that are currently in the 'active' state (i.e., running or exited but still considered active). This is the precise command to list all active services without showing inactive or failed units.
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 list-units --type=service --state=active
Why this is correct
This command filters for active services only.
- ✗
systemctl status --all
Why it's wrong here
status --all shows all units (services, sockets, mounts, etc.), not just services.
- ✗
systemctl show --type=service
Why it's wrong here
show displays properties of a unit, not its active status.
- ✗
systemctl list-unit-files --type=service
Why it's wrong here
list-unit-files shows all unit files, not their runtime state.
