The network manager has requested a 300-workstation expansion of the network. The
workstations are to be installed in a single broadcast domain, but each workstation must have its
own collision domain. The expansion is to be as cost-effective as possible while still meeting the
requirements.
Which three items will adequately fulfill the request? (Choose three).
A.
One IP subnet with a mask of 255.255.254.0
B.
Two IP subnets with a mask of 255.255.255.0
C.
Seven 48-port hubs
D.
Seven 48-port switches
E.
One router interface
F.
Seven router interfaces
255.255.255.0 is usually used for small private networks, yes. It assumes that there’s only one router in the network and has a capacity of up to 253 or 254 clients. This is the most common setup where the router’s IP address is 192.168.1.1.
255.255.254.0 is used for some two-router setups, such as modem-router or modem-router-router (where the modem is set to bridged mode). The routers could be at 192.168.1.1 and 192.168.0.1 each with their own sets of clients.
