What statement about the relationship between the SDN controller and VTEP devices is correct?
- A. The SDN controller collect VM-related information such as MAC and IP, and leads the VTEP devices with this information.
- B. The optimal deployment is one SDN controller per VTEP device.
- C. The optimal deployment is one SDN controller for all VTEP devices
- D. The SDN controller controls VTEP devices using Openflow and tells the VTEP devices which routing/birding protocol to use to dynamically learn the VTEP forwarding table.
Answer: A
