Your boss asks you why you have put in a requisition to buy a bunch of switches when he has bought you a bunch of hubs five years ago. Why did you buy the switches?

A Because there were too many broadcast domains, and a switch breaks up broadcast domains by default

B

Because the hubs kept repeating signals but quit recognizing frames and data structures

C

Because each switch port is its own collision domain

D

Because the cable connecting devices to the hub wore out, and switches were cheaper than a new cable
