Which plan meets the customer requirements?

The customer requires fast failover if any one link or core device fails. Which additional technology should the architect plan on the core VSF fabric to meet these criteria?

Fast Failover has been implemented between Local 1 and Local 2 separated by Routers. During testing Local1 was disabled and all Campus APs backed up to Local 2 flawlessly. But the RAPs did not, they all failed.
