   What is a key underlay requirement for supporting EVPN-VXLAN DCI?

   • AMulticast support in the underlay for all VNIs.
   • BA direct Layer 2 connection between all VTEPs.
   • CIP connectivity between all VTEPs, including across the DCI link.
   • DMPLS support in the underlay.

   A network architect is designing an EVPN-VXLAN DCI between two data centers. The architect wants to ensure that only specific VLANs are extended between the sites, while others remain local. The architect is using route targets to control the exchange of EVPN routes. What is the correct approach to achieve this?

   • AConfigure the VNIs on the spine switches to filter the routes.
   • BAssign a unique route target to each VNI and configure the import/export route targets on the VTEPs to only accept the desired VNIs.
   • CUse different route distinguishers for each VNI to control the exchange.
   • DUse the same route target for all VNIs and rely on the VLAN-to-VNI mapping to control the exchange.

   In an EVPN-VXLAN DCI, what is the role of the IP prefix in a Type-5 route?

   • AIt is used to identify the VTEP's IP address.
   • BIt identifies the VXLAN VNI for the subnet.
   • CIt identifies the subnet that is reachable via the advertising VTEP.
   • DIt is used to identify the MAC address of the gateway.

   In a DCI scenario, what is the role of a local VTEP?

   • AIt provides a default gateway for all hosts in the data center.
   • BIt encapsulates traffic from local hosts and forwards it to remote VTEPs.
   • CIt acts as a route reflector for BGP EVPN routes.
   • DIt only decapsulates traffic received from remote VTEPs.

   What is a primary benefit of using EVPN-signaled VXLAN for data center interconnect (DCI) compared to traditional DCI methods such as OTV or VPLS?

   • AIt automatically encrypts all traffic between sites without additional configuration.
   • BIt eliminates the need for any IP connectivity between data centers.
   • CIt provides a standards-based control plane that enables multi-vendor interoperability and integrated Layer 2/Layer 3 services.
   • DIt requires a dedicated physical fiber connection between data centers.
