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

Explanation:
of 255.255.254.0 can absorb 510 hosts being 23 bits mask and also 7*48 port
switches can handle this much hosts and router interface is required to be minimum to avoid
unnecessary wastage hence the answers.
