A network administrator is setting up a video conference tool that needs to transmit the same video stream to 100 endpoints on a network. To optimize network resources, which traffic type should be implemented?
Multicast is the correct answer because it allows the transmission of data packets to multiple destinations using a single transmit operation by delivering data to a group of destination computers simultaneously. This is particularly useful for applications like video conferencing. Unicast, on the other hand, would involve setting up a separate connection for each endpoint, which consumes more bandwidth and resources. Broadcast would send the stream to all network devices, not just the intended recipients, leading to unnecessary network congestion. Anycast sends data to the nearest or best destination among a group, which would not be suitable for ensuring all intended participants receive the broadcast.
