Which is not a function of the Cisco ISE profiling service?

The function of the Cisco ISE profiling service encompasses various capabilities that enhance network visibility and control. One of these functions is maintaining a learned inventory of endpoints, which is the responsibility indicated in option C. Profiling goes beyond merely categorizing based on authentication; it analyzes devices on the network to understand their characteristics and behaviors.

The correct answer highlights that Cisco ISE maintains user access policies based on endpoint classification is indeed a critical function of the system. However, what's important here is that the primary profiling service is centered around the identification and classification of devices, not the maintenance of access policies. Access policies are generally defined by administrators and apply to various endpoints based on their profiles rather than being maintained automatically by the profiling service itself.

As for the ability to profile endpoints, while 802.1X is a common method used by ISE for authentication, it is not the sole method. For instance, Cisco ISE can also gather profiling information from devices that connect via Mac authentication bypass (MAB) or web authentication, thus ensuring that a range of endpoints can be profiled regardless of the authentication type. This differentiates the types of functions available under profiling compared to user access policy maintenance.

Hence, option B correctly identifies an aspect not directly managed by
