   A VXLAN fabric uses BGP-EVPN. A VTEP receives a unicast frame from a local host with a destination MAC that is not in its MAC table. The VTEP also does not have an EVPN route for this MAC. What should the VTEP do?

   • ASend the frame to the route reflector only.
   • BFlood the frame to all VTEPs in the VNI using unicast replication.
   • CSend the frame to the multicast group for the VNI.
   • DDrop the frame because the destination is unknown.

   A network team is deploying VXLAN in a Dell SONiC environment. They want to use BGP-EVPN but are concerned about the complexity of configuring route targets. What is the purpose of route targets in BGP-EVPN?

   • AThey set the VNI value for the VXLAN tunnel.
   • BThey determine the UDP source port for VXLAN packets.
   • CThey define the multicast group for each VNI.
   • DThey control which VNIs are imported and exported by each VTEP.

   In a VXLAN fabric using multicast-based control plane, a VTEP receives a broadcast frame from a locally attached server. How does the VTEP forward this frame?

   • AIt drops the frame because broadcast is not supported in VXLAN.
   • BIt forwards the frame only to the VTEP that has the destination MAC.
   • CIt sends the frame to all VTEPs in the fabric using unicast.
   • DIt encapsulates the frame in a VXLAN header and sends it to the multicast group associated with the VNI.

   A network administrator is configuring VXLAN on a Dell SONiC switch. They want to use BGP-EVPN as the control plane. Which configuration step is essential for the VTEP to exchange MAC routes with other VTEPs?

   • ACreate a static VXLAN tunnel to each remote VTEP.
   • BConfigure an EVPN address family under BGP and enable the VNI in the EVPN instance.
   • CConfigure a multicast group for the VNI in the underlay.
   • DEnable OSPF on the VXLAN interface.
