In the following exhibit, which would be true if the hub was replaced with a switch?

A. The number of collision domains would increase.
B. The number of collision domains would decrease.
C. The number of broadcast domains would increase.
D. The number of broadcast domains would decrease.

A. Currently all of the computers are within one giant collision domain. Replacing the hub with a switch will create four separate potential collision domains. Switches create micro-segmentation, which increases the number of collision domains and increases bandwidth.
