Select the best answer


Answer: F
Proxy ARP is the technique in which one host usually a router, answers ARP requests intended for another machine. By "faking" its identity. the router accepts responsibility for routing packets to the "real" destination. Proxy ARP can help machines on a subnet reach remote subnets without configuring routing or a default gateway. Proxy ARP is defined in RFC 1027
