Two VTEPs in an XLAN can identify a VXLAN tunnel, and this VXLAN tunnel between the VTEPs will be covered by two NDEs is common to all VNI.

This statement, despite its poor grammar, describes a fundamental concept of VXLAN. A VXLAN tunnel is a logical point-to-point link between two VTEPs (VXLAN Tunnel Endpoints), identified by their source and destination IP addresses in the underlay network. This single tunnel can carry traffic for multiple independent virtual networks. Each virtual network is identified by a unique VNI (VXLAN Network Identifier) within the VXLAN header. Therefore, the tunnel itself is a shared transport mechanism common to all VNIs that need to exchange traffic between those two specific VTEPs. The statement is conceptually correct.
Note: The question is treated as a True/False statement, where 'A' represents 'True'.

This is a True/False style question with a single correct assertion. There are no other options to evaluate as incorrect.

1. IETF RFC 7348, "Virtual eXtensible Local Area Network (VXLAN): A Framework for Overlaying Virtualized Layer 2 Networks over Layer 3 Networks", Section 1, Paragraph 4. It states, "VXLAN is a Layer 2 overlay scheme over a Layer 3 network. It uses MAC Address-in-User Datagram Protocol (MAC-in-UDP) encapsulation to provide a means to extend Layer 2 segments across the data center network." The encapsulation allows a single IP tunnel to carry frames from different segments, distinguished by the VNI.
