   How does an egress VTEP handle a received VXLAN-encapsulated packet?

   • AIt re-encapsulates the packet with a new VNI and forwards it to another VTEP.
   • BIt removes the VXLAN header and forwards the inner Ethernet frame to the appropriate local tenant based on the VNI.
   • CIt forwards the packet to the underlay router for further routing.
   • DIt drops the packet if the VNI is not locally configured.

   What is the purpose of mapping a VNI to a VLAN on a VTEP?

   • AIt assigns a unique MAC address to each tenant.
   • BIt determines the underlay IP address for the VTEP.
   • CIt enables routing between different VNIs without a gateway.
   • DIt allows tenant traffic from a local VLAN to be associated with a specific VXLAN segment for transport across the underlay.

   Which fields are present in the VXLAN header that is added to an Ethernet frame when it is encapsulated for transport over the IP underlay?

   • AVXLAN Network Identifier (VNI), flags, and reserved fields
   • BVNI, sequence number, and time-to-live (TTL)
   • CSource and destination MAC addresses, VLAN ID, and EtherType
   • DSource and destination IP addresses, UDP port, and checksum

   What happens to the original Ethernet frame when it is encapsulated by the ingress VTEP?

   • AIt is compressed to reduce the packet size.
   • BIt is discarded and replaced with a new frame containing only the VNI.
   • CIt becomes the inner payload of the VXLAN packet, with its MAC addresses and VLAN tag preserved.
   • DIt is modified to replace the VLAN tag with the VNI.

   How are VXLAN packets routed across the IP underlay network?

   • AThey are routed based on the VNI in the VXLAN header.
   • BThey are flooded to all VTEPs in the fabric.
   • CThey are switched based on the inner destination MAC address.
   • DThey are forwarded as normal IP packets based on the outer destination IP address, using the underlay routing table.
