Exam 300-430 topic 1 question 278 discussion

Radio Measurement Requests are part of the CCX (Cisco Client Extensions) protocol, specifically CCXv3, which allows the WLC to request clients to perform radio measurements. These measurements help track client locations more accurately and frequently, especially when clients roam between APs. This feature is essential for maintaining location accuracy for CCXv3 clients while still supporting non-CCX and CCXv1 clients. Why not the others? A. Location Calibration: This is used to fine-tune the location accuracy of the WLC by calibrating the environment, but it does not directly address tracking clients at regular intervals or during roaming. B. 802.11u MSAP: This is related to Hotspot 2.0 and network discovery, not client tracking or location services. D. Mobile Concierge: This is a feature for providing location-based services and notifications, but it does not directly handle the tracking of clients at regular intervals or during roaming.
