A student sees destination MAC = FF:FF:FF:FF:FF:FF in an ARP request and destination IP = 192.168.2.45 inside the ARP message. Which interpretation is best?
A
The sender already knows the target MAC and is sending a private unicast frame
B
The request is being routed through the Internet to find a remote website.
C
The frame is broadcast locally so the device using 192.168.2.45 can identify itself and reply with its MAC address.
D
The broadcast MAC means the IP address is no longer needed.
