Which VPN method allows only specific traffic destined for the corporate network to pass through the tunnel?

The correct answer is Split Tunnel. This method allows only specific traffic destined for the corporate network to pass through the VPN tunnel while all other internet traffic is sent directly to the internet without being routed through the VPN. This is particularly useful for optimizing bandwidth and maintaining performance, as users can access local resources or services that do not require a secure connection, while still securely accessing necessary work-related resources.

In contrast, a Full Tunnel directs all traffic through the VPN, including internet traffic, which can lead to slower performance as all data, regardless of its destination, must first pass through the VPN server. An Always-on VPN Tunnel typically supports continuous connectivity but does not specifically tailor the traffic to enter the tunnel. A Site-to-Site Tunnel connects entire networks to each other, rather than individual users or devices, and is not concerned with specific traffic types.
