Question

Which impact does adding a Layer 2 switch have on a network?

A. an increase in the number of dropped frames
B. an increase in the size of the broadcast domain
C. an increase in the number of network collisions
D. an increase in the size of the collision domain

Answer 1

Adding a Layer 2 switch increases the size of the collision domain.

Step-by-step explanation:

Adding a Layer 2 switch has an increase in the size of the collision domain

A Layer 2 switch operates at the data link layer of the OSI model and is responsible for facilitating communication between devices within a local area network (LAN). When a Layer 2 switch is added to a network, it creates a single collision domain for all connected devices. This means that devices connected to the switch can communicate with each other without experiencing collisions.

For example, if there are two computers connected to a switch, they can directly communicate with each other without any collisions. However, if there is no switch and the computers are connected to a hub, all devices connected to the hub would share the same collision domain, resulting in potential collisions.
