Assume you are a network administrator. One of your clients has a network segment that uses a hub

to connect the networked devices. The client tells you that the network users are complaining that

the network seems to be running slow. Which of the following would be the best solution for

improving overall network performance for this client.

a$.$ Divide the network into two new segments, using a hub to build each new segment, and

connecting the two segments with a third hub.

b$.$ Replace the hub with a switch.

c$.$ Configure the throttle setting on each port of the hub, to ensure that no device is allowed to

monopolize network traffic.

d$.$ Upgrade the NICs in all the computers and upgrade the network cables connecting all the

computers to the hub.
