Q. 93

Which two statements accurately define IP addressing rules? (Choose Two)

A.IP multicast addresses start with 240

B.A host portion of all 1’s indicates a network broadcast

C.The value of zero (0) in the host portion means “all hosts” on the network

D.IP addresses are four octets long and contain a network portion and a host portion

C is incorrect; to flood a message to all host of a network, the IP address would contain the network identification and then all 1s (represented by 255) in the host portion of an IP.
