Question

__________ is a networking device used to divide an extensive network into smaller segments.

switch

bridge

protocol

network interface card

Explanation:

A bridge is a networking device that divides an extensive network into smaller segments by connecting multiple network segments at the data - link layer. A switch is also used for connecting devices within a network but its main function is not primarily segmenting a large network in the same way as a bridge. A protocol is a set of rules for data communication, not a device. A network interface card is used to connect a device to a network, not for segmenting a network.

Answer:

B. Bridge
