Answer shold be A.
This question is about the Cisco ACI FLOODING MODE, not Hardware Proxy.
Flooding Mode
Alternatively, you can enable flooding mode: if the destination MAC address is not known, flood in the bridge domain. By default, ARP traffic is not flooded but sent to the destination endpoint. By enabling ARP flooding, ARP traffic is also flooded.
I’m confused about this.
