Which one of the following protocols may need to broadcast some of its messages?
Answer: C
The protocol is DHCP.
A host that has just joined a network has no IP address and does not know where the DHCP server is. It therefore sends its DHCPDISCOVER (and usually its DHCPREQUEST) as a broadcast, from 0.0.0.0 to 255.255.255.255, so that any server on the local network can answer. Servers may broadcast their replies too, since the client cannot yet receive unicast IP traffic.
SMTP, FTP and HTTP all run over TCP connections between two known hosts, which are point-to-point by definition, so they never broadcast.
