What is true regarding 802.11k? 802.11k is a standard that provides mechanisms for APs and clients to dynamically measure the available radio resources in a wireless network. 802.11k defines radio resource management (RRM) functions, such as neighbor reports, link measurement, beacon reports, etc., that allow APs and clients to exchange information about the RF environment and make better roaming decisions. The other options are incorrect because they describe other standards, such as 802.11r, 802.11v, or 802.11ax.

A. It extends radio measurements to define mechanisms for wireless network management of stations
B. It reduces roaming delay by pre-authenticating clients with multiple target APs before a client roams to an AP
C. It provides mechanisms for APs and clients to dynamically measure the available radio resources
D. It considers several metrics before it determines if a client should be steered to the 5GHz band, including client RSSI
