   In an EVPN-VXLAN environment, what is the primary function of IGMP snooping on a VTEP?

   • ATo intercept and forward IGMP queries to the multicast source
   • BTo learn which local interfaces have receivers for a multicast group and forward multicast traffic only to those interfaces
   • CTo generate IGMP reports on behalf of hosts that do not support IGMP
   • DTo translate IGMP messages into VXLAN encapsulated packets for the underlay

   In an EVPN-VXLAN network using ingress replication for BUM traffic, how does a VTEP forward a multicast packet to remote VTEPs?

   • AIt sends the packet to a multicast group in the underlay that all VTEPs have joined
   • BIt sends the packet to a designated forwarder that then replicates it to all VTEPs
   • CIt floods the packet on all local interfaces and relies on remote VTEPs to pull it
   • DIt creates a separate unicast VXLAN-encapsulated copy of the packet for each remote VTEP in the VNI

   When a host sends an IGMP membership report in an EVPN-VXLAN network, what does the VTEP do with the information?

   • AIt updates its local IGMP snooping table and, if needed, originates an EVPN route to signal the group membership to remote VTEPs
   • BIt sends the report to the multicast source using the underlay multicast group
   • CIt forwards the report to all other VTEPs in the VNI using the IMET route
   • DIt discards the report because IGMP is not supported in VXLAN overlays

   A data center operator is deploying EVPN-VXLAN with multicast. The design goal is to forward multicast traffic only to VTEPs that have active receivers, minimizing unnecessary underlay traffic. The underlay is a spine-leaf fabric with IP multicast enabled. Which EVPN multicast approach should the operator implement?

   • AUse Inclusive Multicast Ethernet Tags (Type 3 routes) to flood multicast to all VTEPs in the broadcast domain.
   • BDisable IGMP snooping and rely on the underlay's native multicast routing to deliver traffic to receivers.
   • CConfigure ingress replication for all multicast groups to avoid underlay multicast dependency.
   • DUse Selective Multicast Ethernet Tags (Type 6 routes) with IGMP snooping to build receiver-specific multicast trees.

   When using underlay multicast to forward BUM traffic in EVPN-VXLAN, what do VTEPs use to receive multicast traffic for a VNI?

   • AA broadcast address in the underlay
   • BThe VXLAN network identifier as the destination IP address
   • CA unicast tunnel to each remote VTEP
   • DA unique multicast group address in the underlay that is mapped to the VNI
