Reveal correct answer
Correct answer: A
A.
Runlevel 0 is used to halt (shut down) the system. If set as the default runlevel, the system will immediately shut down on boot, making it unusable. Therefore, it should never be used as the default runlevel.
B.
Runlevel 1 is single-user mode, often used for system maintenance or recovery. While not ideal for regular use, it can be set as the default in specific scenarios, especially on servers requiring limited access.
C.
Runlevel 2 is a multi-user mode without networking (on some systems). It can be used as the default for systems that don’t require network access.
D.
Runlevel 5 provides a graphical interface with networking. It is often used as the default runlevel for desktop environments.
