An engineer configured a bridge domain with the hardware-proxy option for Layer 2 unknown unicast traffic. Which statement is true about this configuration?

A.

The leaf switch drops the Layer 2 unknown unicast packet if it is unable to find the MAC address in the local forwarding tables.

B.

The Layer 2 unknown hardware proxy lacks support of the topology change notification.

C.

The leaf switch forwards the Layers 2 unknown unicast packets to all other leaf switches if it is unable to find the MAC address in its local forwarding tables.

D.

The spine switch drops the Layer 2 unknown unicast packet if it is unable to find the MAC address in the proxy database.
