   A network engineer is troubleshooting a VXLAN issue where a host can ping its default gateway but cannot reach a host on a different VTEP in the same VNI. The engineer checks the EVPN route table and sees Type-3 routes but no Type-2 routes for the remote host's MAC. What is the most likely cause of this issue?

   • AThe local VTEP is not configured with an anycast gateway, so it cannot route to the remote host.
   • BThe remote VTEP is not advertising Type-2 routes for the VNI, possibly due to a missing VNI-to-VLAN mapping or EVPN configuration error.
   • CThe underlay network is not forwarding UDP port 4789 traffic between the VTEPs.
   • DThe remote host is in a different VNI, and the local VTEP is not configured for inter-VNI routing.

   What happens to a broadcast frame in an EVPN-VXLAN network?

   • AIt is sent only to the VTEP with the destination MAC
   • BIt is dropped by the VTEP
   • CIt is routed to the default gateway
   • DIt is encapsulated and sent to all VTEPs in the same VNI

   An administrator has configured EVPN-VXLAN on two leaf switches and wants to verify that the VXLAN tunnel is operational. The administrator runs 'show evpn vxlan' and sees the local VTEP address and VNI, but no remote VTEPs are listed. What is the most likely cause of this issue?

   • AThe VNI is not mapped to a VLAN on the local switch.
   • BThe remote VTEP is not configured with the same VNI, or the EVPN BGP session is not established between the VTEPs.
   • CThe local VTEP's loopback interface is not configured with an IP address.
   • DThe underlay routing protocol is not advertising the loopback routes.

   An enterprise is deploying EVPN-VXLAN and needs to provide routing between two different VLANs (VLAN 10 and VLAN 20) that are mapped to different VNIs. The design requires that hosts in VLAN 10 can communicate with hosts in VLAN 20 without leaving the fabric. Which configuration is required on the leaf switches to enable this inter-VLAN routing?

   • AConfigure static routes on the hosts pointing to the VTEP's IP address for inter-VLAN traffic.
   • BUse the spine switches to route between VNIs by configuring VXLAN on the spine.
   • CConfigure a single IRB interface with both VNIs and use policy-based routing to separate traffic.
   • DConfigure an IRB interface for each VNI with an anycast gateway IP address, and enable routing between the IRB interfaces.
