Which of the following is NOT an Authenticated Tunnel Option in Zscaler?

The choice of ZTunnel - SSH Mode as the option that is not an Authenticated Tunnel Option in Zscaler is accurate because Zscaler utilizes specific tunneling methods designed to enhance security and performance for authenticated traffic. Authenticated tunnels are essential for establishing secure connections while enabling advanced security features.

ZTunnel with Local Proxy, ZTunnel - Route-Based, and ZTunnel - Packet Filter Based are all established methods employed by Zscaler to create authenticated tunnels. They align with how Zscaler deploys its services to securely route user traffic through its cloud platform, ensuring both connectivity and security policies are enforced.

SSH Mode, however, is typically associated with secure shell protocols used for remote access and does not fit within the framework of authenticated tunneling methods provided by Zscaler for their secure web gateway services. This particular functionality is more related to direct secure communications rather than a method of creating a secure tunnel aligned with Zscaler's architecture.
