A wireless administrator has configured a WLAN; however, the clients need access to a less congested 5-GHz network for their voice quality. What action must be taken to meet the requirement?

The correct answer is D. enable Band Select. The 2.4-GHz band is often congested. Clients on this band typically experience interference from Bluetooth devices, microwave ovens, and cordless phones as well as co-channel interference from other access points because of the 802.11b/g limit of three non-overlapping channels.

Explanation

The 2.4-GHz band is often congested. Clients on this band typically experience interference from Bluetooth devices, microwave ovens, and cordless phones as well as co-channel interference from other access points because of the 802.11b/g limit of three non-overlapping channels. You can use this feature to combat these sources of interference and improve overall network performance. Band direction enables client radios that are capable of dual-band (2.4- and 5-GHz) operation to move to a less congested 5-GHz access point. Band selection works by regulating/suppressing probe responses from the clients? 2.4 GHz radio. It makes 5-GHz channels more attractive to clients by delaying probe responses on the 2.4-GHz https://community.cisco.com/t5/wireless-mobility-documents/load-balancing-and-band-select-on- the-cisco-wireless-lan/ta-p/3128513#toc-hId--1894160999
