Which statement is true of an ARP request entering into a switch?

A. The source MAC address of the frame will be all Fs.
B. The destination MAC address of the frame will be all Fs.
C. The switch will only forward the ARP request to the port for the destination computer.
D. The switch will respond directly back with an ARP reply.

B. The destination MAC address for broadcasts are always all Fs, such as ffff.ffff.ffff.

ARP broadcasts a request IP packet to all the machines on the LAN and asks if any of the machines are using that particular IP address. When a machine recognizes the IP address as its own, it sends a reply so ARP can update the cache for future reference and proceed with the communication.
