Which type of message is sent to all hosts on a remote network?

• A. Unicast
• B. Broadcast
• C. Directed Broadcast
• D. Multicast

Answer: (C)

When a message is meant for every host, you have to consider the scope of delivery. A standard broadcast targets all hosts on the local network segment, and routers typically do not forward those broadcasts beyond their local broadcast domain. To reach every host on a remote network, you use a directed broadcast: a packet addressed to the broadcast address of the remote network, which a router forwards into that network so every host there receives it. This is why directed broadcast is the correct choice for delivering a message to all hosts on a remote network. In practice, many networks block directed broadcasts to prevent abuse, but the concept is specifically about targeting the broadcast address of a remote network.
