Fill in the blank: A _______ is used by a VPN gateway to send traffic as if it were a physical interface.
A . VPN Tunnel Interface
B . VPN community
C . VPN router
D . VPN interface

Answer: A

Explanation:

Route Based VPN

VPN traffic is routed according to the routing settings (static or dynamic) of the Security Gateway operating system. The Security Gateway uses a VTI (VPN Tunnel Interface) to send the VPN traffic as if it were a physical interface. The VTIs of Security Gateways in a VPN community connect and can support dynamic routing protocols.
