   Two data centers are interconnected using EVPN-VXLAN. Each site has its own Layer 3 gateway (IRB) for a common VLAN 200. The network team wants to ensure that traffic between hosts in VLAN 200 on different sites is routed locally at each site, rather than being sent across the DCI to be routed. What must be configured to achieve this?

   • AConfigure the IRB interface with different IP addresses on each site.
   • BDisable the IRB interface on one site to avoid a routing loop.
   • CAdvertise the IRB interface IP address (anycast gateway) via EVPN Type-5 routes from both sites.
   • DUse a single IRB interface on one site and extend the VLAN to the other site.

   Two data centers are connected via a routed IP network. A VTEP in DC1 needs to send VXLAN-encapsulated traffic to a VTEP in DC2. The network team has verified that BGP EVPN sessions are established and routes are being exchanged. However, traffic between the sites is not working. What is the most likely cause?

   • AThe BGP route targets are not configured on the VTEPs.
   • BThe VTEPs are using different VNI values for the same VLAN.
   • CThe VTEPs are not in the same OSPF area.
   • DThe MTU on the underlay path is too small to carry the VXLAN-encapsulated frames.

   What is the purpose of a Route Target (RT) in EVPN for DCI?

   • ATo map VLANs to VNIs.
   • BTo control which routes are imported and exported between sites.
   • CTo encrypt EVPN routes.
   • DTo uniquely identify a VTEP in the network.

   An enterprise is interconnecting two data centers using EVPN-VXLAN. They need to advertise a specific /32 host route for a server that is not directly connected to a VTEP but is reachable via a legacy router. The network team wants to ensure this route is advertised across the DCI without extending the VLAN. Which EVPN route type should be used?

   • AType-3 (Inclusive Multicast Ethernet Tag Route)
   • BType-5 (IP Prefix Route)
   • CType-2 (MAC/IP Advertisement Route)
   • DType-1 (Ethernet Auto-Discovery Route)
