Which of the following is a key feature of Cisco ISE regarding endpoint visibility?

The key feature of Cisco ISE regarding endpoint visibility is device identification and classification. Cisco Identity Services Engine (ISE) provides the ability to accurately identify devices that connect to the network, which is crucial for effective security policy enforcement and operational management. By recognizing the type of devices—whether they are laptops, smartphones, printers, or IoT devices—network administrators can apply proper access controls tailored to the specific characteristics and security requirements of each device type.

This device identification process often involves various methods, such as MAC address identification, profiling via DHCP fingerprints, and RADIUS attributes. Once devices have been classified, Cisco ISE can enforce appropriate network policies, which improve security by ensuring that each device has the necessary permissions for its role in the network environment.

While the other options play important roles in network management, they do not directly relate to the endpoint visibility feature that is central to Cisco ISE's functionality. Network performance analytics focuses on the performance metrics of the network rather than its components, data encryption management concerns the safeguarding of data, and traffic shaping capabilities deal with bandwidth management rather than visibility and identification of endpoints. Therefore, device identification and classification is the correct focus here, as it directly addresses the need for visibility into the types and roles of connected devices within
