A large campus network has deployed two wireless LAN controllers to manage the wireless network WLC1 and WLC2 have been configured as mobility peers. A client device roams from AP1 on WLC1 to AP2 on WLC2, but the controller's client interfaces are on different VLANs. How do the wireless LAN controllers handle the inter-subnet roaming?

A. WLC1 marks the client with an anchor entry in its own database. The database entry is copied to the new controller and marked with a foreign entry on WLC2. B. WLC2 marks the client with an anchor entry in its own database. The database entry is copied to the new controller and marked with a foreign entry on WLC1. C. WLC1 marks the client with a foreign entry in its own database. The database entry is copied to the new controller and marked with an anchor entry on WLC2. D. WLC2 marks the client with a foreign entry in its own database. The database entry is copied to the new controller and marked with an anchor entry on WLC1.
