   What is the purpose of a VNI in a VXLAN network?

   • AIt identifies a specific VXLAN overlay segment
   • BIt identifies the underlay routing instance
   • CIt identifies the MAC address of the destination host
   • DIt identifies the VTEP's IP address

   A service provider is designing a multi-tenant data center network where each customer requires isolated Layer 2 segments that can span across multiple racks in different pods. The underlay is an IP fabric using OSPF. The design team wants to avoid running STP across the fabric and needs a solution that provides tenant isolation while allowing MAC addresses to be learned through a centralized control plane rather than data-plane flooding. Which approach satisfies these requirements?

   • AImplement MPLS L3VPN with VRFs and use LDP for label distribution.
   • BDeploy VXLAN with EVPN signaling, using MP-BGP to advertise MAC/VNI routes between VTEPs.
   • CUse traditional VLAN trunking with 802.1Q and enable Rapid Spanning Tree Protocol on all inter-switch links.
   • DConfigure VXLAN with static unicast tunnels and enable head-end replication on each VTEP.

   A network engineer is configuring a new leaf switch as a VTEP in an existing EVPN-VXLAN fabric. The engineer has configured the loopback interface as the VTEP source and has enabled EVPN. Which additional configuration is required to ensure the VTEP can advertise and receive MAC routes for a specific VNI?

   • AConfigure a static route on the leaf switch pointing to the spine for VXLAN traffic.
   • BConfigure the VNI as a VLAN interface with an IP address for routing.
   • CMap the VNI to a VLAN on the leaf switch and configure the VNI in the EVPN routing-instance.
   • DEnable multicast on the leaf switch for VXLAN flooding.

   A network engineer is verifying VXLAN data plane operation on a leaf switch. The engineer sends a known unicast frame from a local host to a remote host on the same VNI. Which sequence of actions occurs on the local VTEP?

   • AThe VTEP floods the frame to all VTEPs in the VNI using multicast, and the remote VTEP decapsulates and delivers it.
   • BThe VTEP strips the VLAN tag, adds a VXLAN header, and forwards the frame to the default gateway for routing.
   • CThe VTEP looks up the destination MAC in its EVPN MAC table, encapsulates the frame with a VXLAN header and UDP/IP headers, and forwards it to the remote VTEP's IP address.
   • DThe VTEP sends the frame to the spine, which performs the VXLAN encapsulation and forwards it to the destination.
