XK0-006 Which three are valid systemd unit types? Practice Question
Which three are valid systemd unit types?
⚠ Common exam trap
Candidates often mistakenly select 'process' and 'job' as valid systemd unit types because they sound plausible, but they are not part of the official list of systemd unit types. This confusion arises from general Linux terminology versus systemd-specific unit definitions.

Correct answer & explanation
✓
socket
B (socket), C (service), and D (timer) are all valid systemd unit types. A socket unit encapsulates a local IPC or network socket in the system for socket-based activation, a service unit describes a process controlled and supervised by systemd, and a timer unit provides a mechanism for triggering activation of other units based on time events. These are among the 12 standard systemd unit types defined in the systemd documentation.
