Which statement about a Versa spoke-to-hub-only topology is true?

In a spoke-to-hub-only topology, the only prefixes advertised by default are the hub routes, and the spoke routes are not re-advertised by the hub branch. This topology is used when spokes do not have to communicate with each other, and a classic example is a network of ATM cashmachines where devices communicate exclusively with resources in the customer data center. The spoke devices, in this case, can send traffic only to networks behind the hub and not to other spokes directly or through the controller.
