What occurs in a full tunnel VPN configuration?

1. Only certain traffic is sent through the VPN tunnel

2. All traffic is sent through the VPN tunnel

3. Only data packets are encrypted and sent

4. No additional routing is required at the concentrator

The correct answer is: All traffic is sent through the VPN tunnel

In a full tunnel VPN configuration, all traffic from the client's device is routed through the VPN tunnel to the VPN server or concentrator. This means that not only data packets intended for remote resources but also local internet traffic from the user’s device is sent through the secure tunnel. This configuration provides a high level of security, as all data is encrypted before it leaves the client, protecting it from eavesdropping. By directing all traffic through the tunnel, the full tunnel setup ensures that sensitive data is secure while it is in transit, even if the user accesses public networks. This approach can be beneficial for organizations that require their users to access their internal resources securely, regardless of the user’s location. In contrast, other configurations like a split tunnel would allow only specific traffic to be sent through the VPN, resulting in a more complex configuration and potentially less secure communication when accessing non-corporate resources. Therefore, choosing a full tunnel configuration means prioritizing security for all types of outgoing traffic.
