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 C (Zscaler Client Connector will encapsulate the user ' s traffic in DTLS/TLS tunnels to the ZTE) is correct because Tunnel 2.0 is the all-ports-and-protocols forwarding model for Client Connector.

Why the other options are incorrect:

A. Zscaler Client Connector will encapsulate the user ' s traffic in GRE tunnels to the ZTE: Zscaler Client Connector is the endpoint agent that steers traffic, authenticates users, reports posture, and supplies ZDX telemetry.

B. Zscaler Client Connector will encapsulate the user ' s traffic in IPSec tunnels to the ZTE: IPS inspects traffic inline for exploit signatures and attack patterns, then blocks or resets offending sessions.

D. Zscaler Client Connector will encapsulate the user ' s traffic in HTTP Connect tunnels to the ZTE: Zscaler Client Connector is the endpoint agent that steers traffic, authenticates users, reports posture, and supplies ZDX telemetry.
