Which Cisco ISE feature allows for a learned endpoint inventory?

The feature that allows for a learned endpoint inventory in Cisco Identity Services Engine (ISE) is the Profiler service. This service gathers information about endpoints that connect to the network, which includes devices such as laptops, smartphones, printers, and other types. By utilizing various methods such as DHCP, RADIUS, and other protocols, the Profiler service identifies the characteristics of each endpoint, allowing Cisco ISE to create a comprehensive database of the devices on the network.

Having this learned endpoint inventory is crucial for network security as it enables administrators to set up policies that can control access based on the type of device or its security posture. The Profiler service plays a key role in ensuring that the inventory remains updated and accurate, thus providing the necessary context for policy enforcement within the network.

Other services mentioned do not focus on endpoint inventory in the same way. For instance, the Policy service deals with how network access policies are enforced based on various criteria, while the Authentication service manages user identity verification processes, and the Device administration service is focused on managing access to network devices rather than detailing endpoint characteristics.
