CompTIA Network+ N10-009 Practice Question

Unicast is the ideal traffic type for one-to-one communications. It ensures that data packets are sent from one single host to one specific receiver, making it optimal for direct and private communication like sending updates from a server to a specific client workstation. Multicast, on the other hand, involves a one-to-many relationship where data is sent from one sender to multiple receivers subscribed to a specific group, which is not suitable for the scenario of a one-to-one, private data transaction. Broadcast traffic sends data to all nodes in a network segment indiscriminately, which is inefficient and insecure for targeted updates. Anycast allows routing to the nearest or best destination among multiple possible receivers; however, it is used predominantly in routing scenarios, not specific one-to-one transactions within the same network.
