What is a reason a network administrator would segment a network with a switch?

A. Create more broadcast domains.
B. Create isolation of ARP messages.
C. Create less collision domains.
D. Isolate traffic between segments.

D. A switch creates micro-segmentation, which in turns isolates traffic between two talking computers from other computers that are not part of the communications. This in turn increases bandwidth for the computers that are not part of the communications between the two talking computers.
