Which types of VPNs use VPN gateways?

• A. Host-to-host VPNs
• B. Remote access VPNs
• C. Both A and B
• D. Neither A nor B

Answer: (B)

VPN gateways terminate VPN connections at the network edge and handle authentication, encryption, and routing for traffic coming from remote clients or between networks. In remote access VPNs, individual user devices connect to such a gateway to access the corporate network, so the gateway is the essential entry point. Host-to-host VPNs establish a tunnel directly between two endpoints without routing through a central gateway, so they don’t rely on a gateway to operate. Therefore, the type that uses VPN gateways is the remote access VPN.
