A network engineer created a new wireless network that will be used for guest access.

 To ensure that the guest network uses only lower rates instead of 802.11n data rates, the WMM (Wi-Fi Multimedia) policy of the WLAN should be set to disabled ©. This will prevent the use of 802.11n data rates, which require WMM to be enabled. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide
