Tunneling facilitates what in a network?

• A. Encrypts email traffic
• B. Facilitates one network to pass its data through other network's connections
• C. Prevents any cross-network data flow
• D. Replaces routing tables

Answer: (B)

Tunneling creates a virtual conduit between networks by wrapping packets from one network inside another protocol so they can travel over a different network’s infrastructure. This lets data from one network pass through and reach another network’s connections as if there were a direct link between them. That’s why it best fits the idea of one network passing its data through another network’s connections. While tunnels can carry encrypted traffic, the essential function is encapsulation and transportation across an alternate network path, not specifically encrypting email. It doesn’t stop cross-network data flow; it enables it. It also doesn’t replace routing tables, since routing decisions still determine how to reach tunnel endpoints. In practice, tunneling is a core mechanism behind VPNs, enabling remote networks to communicate over shared networks.
