Question 7

What is the purpose of multicast in a broadcast IP network?

Accepted Answer

To send a single stream to multiple receivers simultaneously without duplicating bandwidth at the source

Answer

To encrypt streams so only authorized receivers can decode them

Answer

To compress streams before transmission to conserve bandwidth

Answer

To assign unique IP addresses to every device on the network
