How should the architect configure the virtual servers on the two appliances?

Creating only one virtual server per appliance might not provide the necessary granularity to handle diverse traffic types or apply distinct policies for different access scenarios. A session policy typically controls user session settings after initial connection, not initial redirection.

While a redirection policy is useful, creating only one virtual server per appliance might be insufficient for complex environments requiring distinct entry points or policy enforcement for different services.

Creating two virtual servers per appliance often allows for separating different types of traffic or services, such as internal versus external access points, or different authentication requirements. Binding a redirection policy enables dynamic routing of client requests to appropriate backend services or different authentication flows based on criteria like URL or host headers.

Creating four virtual servers per appliance might be overly complex and unnecessary unless there are very specific requirements for that many distinct entry points and services, which is not indicated. A session policy controls session parameters rather than initial traffic redirection.
