Physical Assessment

To perform a physical assessment, you need to document the physical topology of the network. Create a diagram with all routers, switches, and hubs. For example, in Figure 1-2, a list of network devices is created and the type and amount of devices is documented. Physical connectivity between devices should also be documented; also list the speed and type of media used between devices.

You will also need to list the LAN technologies being used. The following is a list of possible LAN technologies:

• Fast Ethernet

• Gigabit Ethernet

Finally, document the WAN circuit information and list the WAN technologies being used. The following is a list of possible WAN technologies used:

• Private lines
