Chapter 1
Planning a Network Topology
Administrators must monitor many services that are essential to a large
network at reg-
ular intervals to ensure they are operating properly. This monitoring can
include regu-
lar examination of logs, function testing, and network traffic analysis. The
network
administrator must be capable of configuring these services to log the
appropriate
information and of using Windows Server 2003 tools such as Network Monitor
and the
Performance console. However, an administrator who is familiar with the use
of these
tools does not necessarily know what elements to monitor, what performance
levels to
expect, and how to interpret the log entries. To know how to do these
things, the
administrator must be familiar with the network infrastructure and with the
normal
operations of the network so that any deviation from the baseline is
apparent.
Troubleshooting is one of the primary maintenance functions of a network
administra-
tor. Although much of the infrastructure design and implementation process
revolves
around the creation of a robust network, problems do occur, and in a large
organiza-
tion, network failures can mean reduced productivity and loss of revenue. To
deter-
mine the location of a problem and decide on a course of action to remedy
it, an
administrator must be closely acquainted with the network infrastructure.

c. A network infrastructure includes both hardware and software products.
d. A network infrastructure is a design that does not include specific
hardware
or software products.
2. Which type of network infrastructure includes the selection of the
network and
transport layer protocols that are to be used on the network?
