Given Pool1 (pooled, East US) and the listed workspaces, in which workspace(s) can you register AppGroup1 (a RemoteApp application group for Pool1)?

Application groups must be registered to a workspace in the same Azure region. Pool1 is located in East US. Therefore, AppGroup1, which is associated with Pool1, can only be registered to workspaces also located in East US. Workspace1 and Workspace3 are both in the East US region, making them valid registration targets. Workspace2 is in West US, and Workspace4 is in Central US, so they cannot host AppGroup1. This regional alignment ensures optimal performance and minimizes latency for users accessing the RemoteApps.
