The correct answer isBbecause ClearPass Device Insight providescontinuous visibility and profiling of all devices—including IoT, BYOD, and managed endpoints—on the network. By proactively detecting unknown, rogue, or misbehaving devices before they cause service or security issues, organizations can ensure higher wireless availability and operational continuity.
Relevant extracts from official HPE Aruba Networking documentation:
“ClearPass Device Insight leverages machine learning and crowdsourced device fingerprints to automatically discover, classify, and monitor all devices connected to the network.”
“With proactive detection of abnormal behavior, IT can address issues before they affect network availability or security.”
“Device Insight closes visibility gaps by identifying unmanaged IoT and BYOD devices, reducing risks that could otherwise disrupt wireless service.”
“This proactive approach ensures that the wireless network remains resilient and available to support business-critical users and applications.”
Why the other options are incorrect:
ADevice profiling on APs alone cannot guarantee availability; it is part of traffic management, not proactive issue detection.
CPoE prioritization ensures APs have power but does not address ongoing availability challenges like rogue devices or abnormal behavior.
DClearPass Policy Manager enforces access control policies but does not provide proactive device visibility and anomaly detection to maintain availability.
