In a university setting where users often connect more than five devices to the network, an IT administrator notices some devices are problematic and require frequent upgrades. How can ClearPass assist in identifying the impact of these upgrades?

ClearPass Profiler collects attributes from endpoints to categorize them by type, vendor, and operating system. When an upgrade is required for a specific type of problematic device, the administrator can use this profiling data to instantly view a complete inventory of all such devices on the network. This provides clear visibility into the scope and potential impact of the upgrade, allowing for better planning and targeted action without affecting other, non-problematic devices.

B. Blocking devices is an enforcement action, not a method for identifying the scope or impact of an upgrade.
C. ClearPass is a Network Access Control (NAC) solution; it does not have the native capability to perform firmware upgrades on endpoints.

- Aruba ClearPass Policy Manager 6.11 User Guide, "Profiling Collectors and Namespaces," Page 1. The document states, "ClearPass uses device profiling to collect endpoint context data... This data is used to classify client devices when they connect to the network."

- Aruba ClearPass Policy Manager Data Sheet, "Key Features > Profiler," Page 3. It describes how Profiler provides "precise device visibility" and "discovers and classifies all endpoints," which enables administrators to understand the types and numbers of devices on their network.
