C.
It is dropped by the leaf when the destination endpoint is not present in the endpoint table.
D.
It is forwarded to one of the APICs to perform as a proxy.
Changing the Layer 2 unknown unicast policy from Flood to Hardware Proxy results in the traffic being forwarded to one of the spines to perform as a spine proxy4. If the spine proxy also does not know the address, the packet is discarded4.
