When you create a global desktop entitlement or global application entitlement, you must specify its scope policy. The scope policy determines the scope of the search when Horizon looks for desktops or applications to satisfy a request from the global entitlement.
You can set the scope policy so that Horizon searches only on the pod to which the user is connected, only on pods within the same site as the user's pod, or across all pods in the pod federation.
For global desktop entitlements that contain dedicated pools, the scope policy affects where Horizon looks for desktops the first time a user requests a dedicated desktop. After Horizon allocates a dedicated desktop, it returns the user directly to the same desktop.
