LFCS Service Configuration Practice Question
Which systemd unit type is used to group services and other units together for boot execution?
⚠ Common exam trap
Many candidates confuse 'service' units with the concept of grouping, because services are the most common unit type, but they fail to recognize that only 'target' units can aggregate multiple units into a single boot synchronization point.

Correct answer & explanation
✓
target
In systemd, the 'target' unit type is designed to group services, sockets, timers, and other units into a logical synchronization point for boot execution. Targets do not execute code themselves but instead define dependencies (via Wants, Requires, and After directives) that ensure all associated units are started in the correct order to reach a desired system state, such as multi-user.target or graphical.target.
