An organization has a fully distributed Cisco ISE deployment. When implementing probes, an administrator must scan for unknown endpoints to learn the IP-to-MAC address bindings. The scan is complete on one PSN, but the information is not available on the others.What must be done to make the information available?

A. Cisco ISE must be configured to learn the IP-MAC binding of unknown endpoints via RADIUS authentication, not via scanning. B. Cisco ISE must learn the IP-MAC binding of unknown endpoints via DHCP profiling, not via scanning. C. Scanning must be initiated from the MnT node to centrally gather the information. D. Scanning must be initiated from the PSN that last authenticated the endpoint.
