   In an EVPN-VXLAN fabric with symmetric routing, which VTEP is responsible for performing the routing lookup for inter-subnet traffic?

   • ANeither VTEP; the routing is done by the spine switches.
   • BThe ingress VTEP only.
   • CThe egress VTEP only.
   • DBoth the ingress and egress VTEPs.

   A network administrator is verifying that symmetric routing is working correctly in an EVPN-VXLAN fabric. The administrator checks the forwarding table on a VTEP and sees a route to a remote subnet via the Layer 3 VNI. What does this indicate?

   • AThe VTEP is bridging traffic to the remote subnet.
   • BThe VTEP has a misconfigured VRF.
   • CThe VTEP has learned the route via the EVPN control plane and can route traffic to the remote subnet.
   • DThe VTEP is configured for asymmetric routing.

   What happens to the VXLAN header at the egress VTEP in symmetric routing?

   • AIt is modified to include the destination host's MAC address.
   • BIt is replaced with a new VXLAN header using a different VNI.
   • CIt is kept intact, and the packet is routed to the destination subnet.
   • DIt is removed, and the inner frame is forwarded to the destination host.

   What is the primary responsibility of the egress VTEP in symmetric routing?

   • ATo route the packet to the destination subnet and then send it to the ingress VTEP.
   • BTo maintain the VXLAN tunnel state and forward the packet to the next hop router.
   • CTo perform a Layer 3 lookup and re-encapsulate the packet with a new Layer 3 VNI.
   • DTo decapsulate the VXLAN packet and forward the inner frame to the destination host on the local subnet.

   How is a Layer 3 VNI associated with a VRF in symmetric routing?

   • AThe Layer 3 VNI is dynamically assigned per flow based on the destination MAC address.
   • BThe Layer 3 VNI is only used on the ingress VTEP, while the egress uses the Layer 2 VNI.
   • CEach VRF is mapped to a unique Layer 3 VNI, and this mapping is consistent across all VTEPs.
   • DEach VTEP uses a different Layer 3 VNI for the same VRF to avoid collisions.
