An engineer is designing a network for a customer running a wireless network with a common VLAN for all APs. The customer is experiencing unicast flooding in the Layer 2 network between the aggregation and access layers. The customer wants to reduce the flooding and improve convergence time. Which solution meets these requirements?

A. Migrate all APs to a common Layer 2 access layer switch and run Layer 3 from the aggregation layer to all remaining access layer switches. B. Align HSRP primary and STP root bridges and reduce ARP timers to match CAM timers on the aggregation layer switches. C. Migrate to a Layer 3 access campus design if the APs can run on separate VLANs. D. Align HSRP primary and STP root bridges if the APs cannot run on separate VLANs.
