Answer 8

Correct answer: a

Explanation:

One issue with a large flat network segment is excessive collisions and broadcasts. These will decrease the network performance and throughput. In case of collisions the affected hosts need to back off and wait for a random period of time before resending the frame. In case of broadcast, all hosts need to stop their operations and examining the broadcast frame.

A solution is to segment the flat network into multiple smaller physical segments. This can be done using a bridge, switch, or router. The result is increased collision domains when using a bridge of switch. A router produces multiple collision domain as well as broadcast domains.
