                                                      Question #4

                                                      Which of the following statements about static VXLAN tunnel configuration are correct?

                                                      • A. On an NVE interface, the destination address of a VXLAN tunnel is specified based on the address in the ingress replication list. You can create one NVE interface for multiple VXLAN tunnels.
                                                      • B. One NVE interface must be created for each VXLAN tunnel, and the source and destination IP addresses must be specified for the NVE interface. Therefore, the number of NVE interfaces is the same as the number of VXLAN tunnels on the VTEP.
                                                      • C. An NVE interface can be associated with multiple VNIs. Therefore, you can create one NVE interface when there are multiple BDs.
                                                      • D. One NVE interface must be created for each BD. If there are multiple BDs, multiple NVE interfaces must be created.
