If you can see this check that
There are two main ways for starting services, INIT and XINET. Choose the TRUE statement.
A. | XINET works out what services are running using /etc/init.d.
|
B. | XINET starts services on demand, so is less efficient in resource usage
than INIT.
|
C. | INIT services are either executed at a particular runlevel if the script file
exists, or it is simply not running at that runlevel.
|
D. | INIT can be hard to debug, as services it controls may not be visible in
the process table until a client tries to connect to that service.
|
E. | INIT starts services on demand, and therefore is more efficient than
the runlevel based XINET system.

INIT and the runlevels use init.d. XINET uses /etc/xinetd

XINET is much MORE efficient because it starts services on demand, not less efficient.

True.

This is the main issue agains XINET.

XINET runs services on demand, INIT runs them at a particular runlevel.
