The process of encapsulating data from one protocol for safe transfer over another network is called what?

• A. tunnel
• B. encapsulation
• C. payload tunneling
• D. VPN

Answer: (A)

Tunneling is the process of wrapping a protocol’s packet inside another protocol’s header so it can be sent across a network that doesn’t support the original protocol. This creates a secure, navigable path—a tunnel—through which the encapsulated data travels to its destination. The act of wrapping the payload is encapsulation, but the overall method of transferring that encapsulated data over a different network is tunneling. VPNs use this technique to provide secure transport, but the question is focusing on the mechanism itself, which is tunneling.
