Topic #: 2
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.
When a bridge domain is configured with the hardware-proxy option for Layer 2 unknown unicast traffic, if the spine switch is unable to find the MAC address in the proxy database, it will drop the Layer 2 unknown unicast packet4. This behavior is controlled by the hardware proxy option associated with a bridge domain4.
