Question

1. When the Cisco 2950 switch is first turned on, it behaves like a hub. Why is this so, and what must happen before the switch can send unicast traffic to a specific port

Answer 1

The switch sends broadcast traffic to all ports like a hub to get the number of ports used and build its MAC address table.

Step-by-step explanation:

A network switch is a device used in a LAN to connect all available workstations. Unlike a network hub, it is able to send frames from a host or workstation to another using its MAC address table.

An example of a switch is the Cisco 2950 switch. When it is first turned on, it acts as a hub, broadcasting traffic to all its ports. This process is used to create a MAC address table to get the IP address of workstations and the ports they relate to, enabling it to send unicast traffic to a specific port.
