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