D.

IP ARP suppression

Suggested answer: D

Explanation:

IP ARP suppression (D) is used in VXLAN EVPN environments to minimize flooding.When enabled, it allows the local switch to respond to ARP requests for known hosts, thus preventing the need to flood these requests across the entire network segment1.This feature is particularly useful in scenarios where there is a large amount of ARP traffic that could potentially lead to flooding, as it reduces unnecessary broadcast traffic by handling ARP resolution within the control plane2.
