What is the role of Application PAC in route-based mode?

The role of Application PAC in route-based mode is crucial as it processes traffic based on defined rules and then determines the appropriate routing path for that traffic. In this mode, the PAC (Proxy Auto-Configuration) file guides the web traffic to the Zscaler cloud for filtering and security services, while also allowing for direct access to the internet when necessary.

This means that the Application PAC enables a flexible and dynamic approach to traffic management, ensuring that users benefit from both the security features of Zscaler and unhindered access to the internet when appropriate. It is particularly vital in environments where both internal applications and external web resources are accessed, facilitating optimal traffic flow and management.

The other choices do not accurately represent the functionalities of the Application PAC in route-based mode. For instance, blocking all traffic to the Zscaler cloud does not align with its purpose, which is to enhance security and traffic management. Routing traffic solely to internal servers is also incorrect, as the PAC is intended to manage traffic towards both the Zscaler cloud and the internet. Additionally, establishing VPN connections is not a role of the Application PAC; rather, it focuses on traffic direction and regulation.
