A company wants clients to receive a video stream from a server. What is the advantage of
transmitting this stream as multicast traffic rather than unicast traffic?

A.
The network administrator does not need to configure routing for the stream.

B.
The server does not need to be preconfigured with each endpoint’s IP address.

C.
The endpoints can reside in many different subnets instead of only the server’s local subnet.

D.
The server transmits a single stream rather than many streams.

Explanation:
IP multicast is a method of sending Internet Protocol (IP) datagrams to a group of
interested receivers in a single transmission. It is often employed for streaming media applications
on the Internet and private networks. The method is the IP-specific version of the general concept
of multicast networking.
Note: Sending the same data to multiple unicast addresses requires the sender to send all the
data many times over, once for each recipient.
