broadcast, unicast - correct answer. An ARP request is a ?; an ARP reply is a ?
Address Resolution Protocol (ARP) - correct answer. method to send a packet/frame
to another computer when the sending computer does not know the MAC address of
the receiving computer, just the IP address of it, operates at datalink layer,
Bootstrap Protocol (BootP) - correct answer. host can configure its IP parameters at
boot time, not only assigns IP, but also assigns default router and network mask,
operates at network layer
