   An enterprise operates two EVPN-VXLAN fabrics that are interconnected via a WAN. The network team wants to selectively share only type-5 (IP prefix) routes between the two fabrics, while keeping type-2 (MAC/IP) routes isolated within each fabric. They are using a single MBGP session between the border leaf devices. Which configuration approach achieves this requirement?

   • AUse a route distinguisher that encodes the route type, and filter on the RD value.
   • BDisable the EVPN address family on the WAN session and enable the inet-vpn unicast family instead.
   • CConfigure distinct route targets for type-2 and type-5 routes, and apply an import policy on the border leaves that only accepts the type-5 route target.
   • DConfigure a single route target for all EVPN routes and rely on the BGP community to differentiate type-2 from type-5.

   When setting up an iBGP session between spine and leaf devices for EVPN, which interface is typically used as the BGP session source?

   • ALoopback interface
   • BIRB interface
   • CPhysical interface (e.g., xe-0/0/0)
   • DManagement interface (e.g., fxp0)

   An engineer is designing an EVPN-VXLAN fabric that will carry both MAC/IP routes (type-2) and IP prefix routes (type-5) for inter-VLAN routing. The engineer wants to ensure that type-5 routes are only advertised for specific subnets, while type-2 routes are advertised for all MAC addresses. Which configuration approach achieves this?

   • AConfigure separate route targets for type-2 and type-5 routes.
   • BConfigure a single export policy that matches on the route type and applies different actions.
   • CConfigure the VRF with a different route distinguisher for type-5 routes.
   • DDisable the EVPN address family and use the inet-vpn unicast family for type-5 routes.

   • DType 6 (Multicast)

   What is the primary role of Multiprotocol BGP (MBGP) in an EVPN-VXLAN data center fabric?

   • ATo provide a backup path for OSPF in the underlay network
   • BTo replace VXLAN encapsulation by providing Layer 2 forwarding directly over BGP
   • CTo carry multiple address families, including EVPN, over a single BGP session between spine and leaf devices
   • DTo enable multicast replication for broadcast traffic in the fabric
