Which configuration element is required to define a VXLAN VNI on a Junos device?

A physical interface configured with family inet and a VXLAN encapsulation.

A firewall filter that matches the VXLAN UDP destination port 4789.

A routing instance of type virtual-switch with a vxlan statement specifying the VNI.

An MPLS label-switched path that carries VXLAN traffic.

A data center team is deploying VXLAN on Juniper QFX5100 switches. They have two VTEPs that need to exchange traffic for VNI 200. The underlay is configured with OSPF, and the loopback addresses are advertised. What is the minimum configuration required on each VTEP to establish VXLAN connectivity?

Set the VXLAN network identifier to 200 on the loopback interface.

Configure a static VXLAN tunnel to the remote VTEP's loopback address.

Enable VXLAN on the physical interface connecting to the underlay.

Create a VXLAN interface with VNI 200 and associate it with a VLAN.

Which common misconfiguration would cause VXLAN traffic to be dropped at the VTEP?

Missing routing protocol on the overlay interface.

Incorrect VLAN ID on the physical underlay port.

Mismatched VNI between the local and remote VTEPs.

Incorrect MTU on the underlay interface.

A network engineer is troubleshooting a VXLAN deployment where hosts in the same VNI cannot communicate across two VTEPs. The underlay is reachable, and both VTEPs have the correct VNI configured. The engineer suspects that the VXLAN encapsulation is not being applied to the tenant traffic. Which configuration should be checked first?

Ensure that the VXLAN tunnel is configured with a multicast group.

Check that the underlay routing protocol is advertising the loopback addresses.

Confirm that the physical interfaces are configured with the 'vxlan' family.

Verify that the tenant VLAN is associated with the VXLAN VNI on both VTEPs.
