Which of the following functions of GARP is false?
A gratuitous ARP is an unsolicited, local-broadcast ARP announcement that advertises an IP-to-MAC mapping so receiving hosts can refresh applicable ARP-cache entries. It does not require, or cause, acknowledgement replies from the other hosts. RFC 5944 specifies that a gratuitous ARP is transmitted as a local broadcast and that receivers update an existing ARP-cache entry from the sender protocol and hardware addresses.
