Answer: D

Explanation:

Virtual Tunnel Interfaces (VTI) are used in route-based VPNs. In this type of VPN, the tunnel is treated like a regular interface on the router. This allows for the configuration of routing protocols and the application of routing decisions to the traffic flowing through the VPN tunnel. VTIs simplify the management of routing and make it more flexible in VPN scenarios.
