Which component initiates a secure remote connection to a VPN server?

• A. Network Access Server (NAS)
• B. Tunnel terminating device (VPN server)
• C. VPN Client
• D. Anonymous Proxy

Answer: (C)

The VPN client on the user's device initiates the secure remote connection. It starts the tunnel to the VPN server, performs authentication, and negotiates the encryption and other security parameters (such as the IPsec or TLS handshake). Once the server accepts the client’s credentials and the security parameters are agreed, the tunnel is established and all traffic is encrypted as it travels to the private network. The device at the other end—the VPN server or tunnel terminating device—handles the received encrypted data and forwards it into the internal network, but the initiation always comes from the client. A Network Access Server can host the VPN service, but it is the client that starts the connection, and an anonymous proxy is not involved in establishing a VPN tunnel.
