A network engineer is configuring a Cisco WLC in order to find out more information about the devices that are connecting. This information must be sent to Cisco ISE to be used in authorization policies. Which profiling mechanism must be configured in the Cisco WLC to accomplish this task?
When configuring a Cisco WLC to gather more information about connected devices and send it to Cisco ISE for use in authorization policies, the proper profiling mechanism to configure is DHCP. DHCP profiling allows the WLC to collect device attributes from the DHCP request packets, which include information such as device type and operating system. This collected information can then be sent to Cisco ISE to enhance profiling and apply appropriate authorization policies.
if question about configuring probe on Cisco ISE than both A and D is valid answer. However question is asking what need to be configured on WLC without mentioning probe, therefore D is correct: https://community.cisco.com/t5/security-knowledge-base/ise-profiling-design-guide/ta-p/3739456#toc-hId-888202210
Answer D is the right answer
