To what does Z-Tunnel 2.0 fall back?

Z-Tunnel 2.0 is designed with a mechanism that allows it to revert to an earlier version called Z-Tunnel 1.0 when necessary. This fallback capability ensures that users maintain connectivity and access to resources in scenarios where the newer version may encounter issues or is unable to function optimally due to specific network conditions or configurations. The objective of this design is to prioritize user experience and minimize disruptions, ensuring that users can continue to operate effectively even in less than ideal circumstances.

Other versions mentioned in the choices do not serve as fallback options for Z-Tunnel 2.0; they may offer different features or enhancements, but in the context of maintaining continuity of service, Z-Tunnel 1.0 is the designated fallback that complements the operational framework of Z-Tunnel 2.0.
