Which of the following best describes the function of a MAC layer address (circle best answer): Gets a frame to the next NIC Gets a packet to the correct port Gets a frame to the final destination Gets a frame to the correct socket

Solution

B) get the packet to the correct port

MAC addresses are Data link layer addresses, and they are used to deliver data link layer frames on a LAN. MAC address is used by switches to create a table of which host is connected to which switch interface. A switch will look at the source MAC address to build its MAC address table, and it will look at the destination MAC address, look it up in its MAC address table, and deliver the frame to the correct port.
