An engineer configured a bridge domain with the hardware-proxy option for Layer 2 unknown unicast traffic. Which statement is true about this configuration?
The leaf switch drops the Layer 2 unknown unicast packet if it is unable to find the MAC address in the local forwarding tables.
The Layer 2 unknown hardware proxy lacks support of the topology change notification.
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.
The spine switch drops the Layer 2 unknown unicast packet if it is unable to find the MAC address in the proxy database.
An engineer configured Layer 2 extension from the ACI fabric and changed the Layer 2 unknown unicast policy from Flood to Hardware Proxy. How does this change affect the flooding of the L2 unknown unicast traffic?
It is forwarded to one of the spines to perform as a spine proxy.
It is flooded within the whole fabric.
It is dropped by the leaf when the destination endpoint is not present in the endpoint table.
It is forwarded to one of the APICs to perform as a proxy.
