Which statement is true about 802.11k?

Which statement is true about 802.11k?

• 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
• C. It provides mechanisms for APs and clients to dynamically measure the available radio resources
• D. It considers several metrics before deciding if a client should be steered to the 5 GHz band, including RSSI

Answer: (C)

802.11k focuses on Radio Resource Management, giving APs and stations a formal way to measure the wireless environment and report those measurements so the network can optimize how it uses the spectrum and supports roaming. The correct statement says it provides mechanisms for APs and clients to dynamically measure the available radio resources, which is exactly what 802.11k defines—measurement requests and reports that reveal channel utilization, interference, neighbor APs, and other environmental data that help the network make smarter decisions. The other options describe capabilities associated with other standards. Pre-authenticating clients with multiple target APs to reduce roaming delay is a feature tied to fast BSS transition (802.11r). Steering decisions that consider RSSI and other metrics are more about network-assisted roaming and steering (802.11v), with 802.11k supplying the measurement data that such decisions can use.
