4.3.1 Network Requirements
As the following figure shows, two groups of computers are connected to Switch A, and
Switch A is connected to the DHCP server. All devices on the network are in the default
VLAN 1. All computers get dynamic IP addresses from the DHCP server. For management
convenience, the administrator wants to allocate separate address spaces for the two
groups of computers.
