Q

A network design engineer has been asked to design the IP addressing scheme for a customer network. The network will use IP addresses from the 192.168.30.0/24 network. The engineer allocates 254 IP addresses for the hosts on the network but excludes 192.168.30.0/24 and 192.168.30.255/24 IP addresses. Why must the engineer exclude these two IP addresses?

A

192.168.30.0/24 is the network IP and 192.168.30.255/24 is the IP broadcast address.

Q

What are three characteristics of a multicast transmission? (Choose three.)

A

1- Router will not forward multicast address in the range of 224.0.0.0 to 224.0.0.255
