Which of the following statements best describe what a switch does with a frame?

Answer: C. A switch floods broadcast frames, multicast frames (if no multicast optimizations are enabled), and unknown unicast destination frames (frames whose destination MAC address is not in the MAC address table) except for the incoming interface.

What a switch does with a frame destined for an unknown address by the MAC address table?

If the address is in the table, the frame is forwarded out the port associated with the MAC address in the table. When the destination MAC address is not found in the MAC address table, the switch forwards the frame out of all ports (flooding) except for the ingress port of the frame.

Which of the following statements describes part of the process of how a LAN switch decides to forward a frame destined for a broadcast MAC address quizlet?

Which of the following statements describes part of the processes of how a LAN switch decides to forward a frame destined for a broadcast MAC? It forwards the frame out all interfaces in the same VLAN except for the incoming interface.

What are the functions of a switch quizlet?

What is the basic function of a switch ? The switch is supposed to perform to receive information from any source connected to it and dispatch that information to the right source.
