Which system initialization system is used in SLES 15?
A . undev
B . init
C . System V
D . systemd
E . UEFI
Answer: D
Explanation:
The program systemd is the process with process ID 1. It is responsible for initializing the system in the required way. systemd is started directly by the kernel and resists signal 9, which normally terminates processes. All other programs are either started directly by systemd or by one of its child processes.
