It determines the lowest common speed and duplexing between switches.
Enhances synchronization of frames between a device and a switch.
Determines whether layer 3 is using IPv4 or IPv6.
When a network switch receives an Ethernet frame, what information does it use to build and populate its MAC address table?

The source MAC address and the port number where the frame was received.
he destination IP address and the source MAC address.
The source MAC address and the destination port number.
