Correct Answer: B, CTo meet the requirements of using multicast for broadcast, unknown unicast, and multicast replication in a VXLAN EVPN, one VNI to one multicast group is a commonly used method as it simplifies the configuration and management, ensuring each VNI is mapped to a distinct multicast group. Additionally, many VNI to one multicast group is another valid method where multiple VNIs share the same multicast group, which can be useful for reducing the total number of multicast groups in use. Both methods are commonly used in VXLAN implementations to handle BUM (Broadcast, Unknown unicast, and Multicast) traffic efficiently.
