Which of the following secures all IP unicast traffic?

Z-Tunnel 2.0 extends forwarding beyond web proxy traffic by securing all IP unicast traffic through DTLS/TLS tunnels to the Zero Trust Exchange. This enables Cloud Firewall and other controls to inspect all TCP and UDP ports, and ICMP where supported, rather than only browser HTTP/HTTPS flows. Option D (Z-Tunnel 2.0) is correct because Tunnel 2.0 is the all-ports-and-protocols forwarding model for Client Connector.

Why the other options are incorrect:

A. Secure Shell (SSH): RDP, SSH, and VNC are privileged remote access protocols for desktop, shell, and graphical administration.

B. Tunnel with local proxy: Tunnel with Local Proxy creates a loopback proxy path on the endpoint for forwarding selected traffic.

C. Enforce PAC: Enforced PAC controls browser or system proxy behavior. Z-Tunnel 2.0 is the mechanism that secures all IP unicast traffic from the endpoint.
