You are a network administrator for your Windows Server 2003 domain and you are updating the
network configuration for your company. You have used part of the 191.99.74.0/16 IP address
range that your company owns and segmented the networks in this new location in such a way to
allow for 60 hosts per subnet currently and also allow for an anticipated growth of 15% for the
client systems.
Your design also calls for adding a routing configuration that will allow you to forward IP multicast
traffic and the use of the Internet Group Management Protocol (IGMP). You have decided to use
the Routing and Remote Access Service on your Windows Server 2003 system to handle this
requirement in your environment. You also need to define the standards for your network nodes
with regard to multicasting on your network.
What is a specific characteristic that is required of a host or network node that is multicast-capable?
Select the best answer.
A.
The network node must be able to use a multicast routing protocol to propagate multicast
group listening information to other multicast-capable nodes.
B.
The network node must be able to listen for all multicast traffic on all attached networks. Upon
receiving multicast traffic the node would have to forward the multicast packet to attached
networks where other nodes are listening or where downstream routers have nodes that are
listening.
C.
The network node must be able to listen for IGMP membership report messages and update
the TCP/IP multicast forwarding table.
D.
The network node must be able to register the multicast addresses being listened to by the
node with local routers so that multicast packets can be forwarded to the network of the node.
