Kathy works in an all-Windows environment and has been told that a Unix network needs to also be set up to support some new applications that cannot run on Windows systems. She has read that she needs to set up an NIS server. Why would she need to set this up?

A.
To allow Windows and Unix clients to share files through a virtual file system

B.
Security purposes

C.
To include a type of firewall that works in Unix environments

D.
Central administration

Explanation:
In a Unix environment, systems use certain system configuration files,
and in a network it is usually easier if all of the systems contain identical
configuration files. Instead of maintaining these files individually for each
computer, NIS is a way to have all of these configuration files stored and
maintained locally. This allows for central administration. NIS has no real security
components.
