A network administrator is a professional responsible for creating, managing and maintaining a network of computers that work at the same time for a certain thing. The greater the number of computers added to this network, the more difficult it will be the work of the network administrator who has to establish factors for the network to be able to house all users, in addition to creating factors that allow users to do their activities independently how intense it is.

One hundred users is a large number for a computer network, so we can say that building and maintaining this network will be a difficult job for the network administrator.
