You are designing a network for a small business. 

You available the following equipment:

Gigabit Manageable Ethernet switches  

48 port switches

24 port switches

8  port switches

You can use any number of these switches.

You do not have to use every port on any switch. Document the

unused ports as available for later expansion.

Routers with 2 Gigabit Ethernet interfaces

Gi0/0

Gi0/1

and one serial interface

Ser0

You can use any number of these routers.

You do not have to use every interface on any router. Document the

unused interfaces as available for later expansion.

You also have one (and only one) Router/firewall with two

At Site A you have 5 rooms which need to support up to 45 hosts each.

They can all be on the same subnet (but don't necessarily have to be)

At Site B you also have 25 servers behind a router/firewall. These hosts

       are to be firewalled from internal as well as external hosts.

The router/firewall has 2 Ethernet interfaces (eth0 and eth1)

At Site C you have 4 rooms with 20 workstations each.

They can all be on the same subnet (but don't necessarily have to be)

Site A links to Site B via a dedicated Serial interface. 

Site B links to Site C via a dedicated Serial interface.

Site C links to the ISP via a dedicated Serial interface.

Divide up the /23 you have been assigned to accommodate the needs of the site.
