Your network has 20 computers connected to a hub You want to

Your network has 20 computers connected to a hub. You want to increase performance by reducing the size of the collision domain as much as possible. Which of the following devices can be used to do this?

A. A hub

B. A bridge

C. A switch

D. None of the above

Solution

C is correct. While all Layer 2 devices split collision domains, switches create a separate collision domain for each port.

A, B, and D are incorrect. A is incorrect because hubs are Layer 1 devices and extend collision domains. B is incorrect because a bridge is a Layer 2 device, but can split the network only into two collision domains. D is incorrect.
