Selected Answer: B
I believe the trap here is that the border node in a Cisco SD-Access fabric does not perform network virtualization itself; as per Cisco U materials: The fabric border node is responsible for network virtualization “interworking” and as mentioned bellow: The border node can "extend" network virtualization https://www.cisco.com/c/en/us/td/docs/solutions/CVD/Campus/cisco-sda-design-guide.html#Border_Node Meanwhile its clearly stated: VXLAN encapsulation/de-encapsulation—Packets and frames received from outside the fabric and destined for an endpoint inside of the fabric are encapsulated in fabric VXLAN by the border node
