Suggested answer: A

Explanation:

Configuring Proxy ARP on leaf devices in an EVPN overlay network enables them to respond to ARP requests on behalf of other hosts. When the leaf device knows the MAC of the intended destination, it can reply to ARP requests with its own MAC address, thus facilitating local resolution and avoiding unnecessary ARP traffic across the overlay.
