XK0-006 Practice Question: Which THREE of the following are valid systemd…
Which THREE of the following are valid systemd unit types?
⚠ Common exam trap
CompTIA often tests the distinction between systemd-native unit types and external scheduling tools like cron, so candidates may mistakenly think `cron` is a systemd unit type because both handle scheduling, but systemd uses `timer` units instead.
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
✓
timer
A is correct because `timer` is a valid systemd unit type used to schedule and trigger other units (typically services) based on time events, similar to cron but integrated with systemd. Timers can be monotonic (relative to system events) or real-time (calendar-based), and they are defined in `.timer` files.
