For the Network Infrastructure exam, you should be familiar with all of the protocols and services described in this chapter, particularly all aspects of TCP/IP.
If at all possible, you should practice using a network with several workstations and servers. Experience with larger networks (multiple locations, subnets, and routers) is even better.
The following sections describe exercises you can perform to become more familiar with Windows 2000 network infrastructure.
In the Real World
If you are unable to access a Windows 2000 network for study, you may wish to look at VMWare (http://www.vmware.com). This product allows you to run several operating systems concurrently and network between them. With a reasonably fast computer (700 MHz or faster) and a large amount of RAM (at least 128 MB), you should be able to run 2-3 virtual machines running Windows 2000 Professional or Server.
For each machine in your network, perform these steps:
Add TCP/IP to the list of protocols if it is not already installed.
Assign an IP address. Use the private IP address ranges listed in the Study Guide to avoid conflicts.
Use the ping
utility from another computer to
verify that the computers can
communicate.
Either on paper or in a real network, divide a class C IP network into subnets and calculate the correct subnet masks.
Enable the Packet Filtering feature and configure several filters,
then test to ensure that the ports have been blocked. (You can use
the telnet
command to connect with any port
number.)
