What is the purpose of "systemd" units and targets, and how do they differ from traditional SysV init scripts?
Correct! Well done.
Incorrect.
The correct answer is A) Systemd manages services, devices, and mounts as declarative "unit" files (.service, .mount, .target), with dependency-based parallel startup, socket activation, and supervision — unlike SysV init's sequential scripts run in a fixed runlevel order
Correct Answer

Systemd's unit-based, dependency-aware, and parallelized approach (along with features like automatic service restart and socket activation) generally allows faster boot times and more robust service management compared to the largely sequential SysV init model.
