Which type of address does a switch use to build the MAC address table? destination MAC address source IP address destination IP address source MAC address

switch uses the source MAC address to build the MAC address table. When a switch receives a frame, it looks at the source MAC address in the frame's header and associates that MAC address with the port on which it was received. This process helps the switch build its MAC address table, which is used to forward frames to the correct destination devices based on their MAC addresses.
