A customer deploys a new WLAN that has 60 APs and 10 SSIDs. The customer uses a 40-MHz channel design for a 5-GHz WLAN that supports 10 nonoverlapping channels. The customer uses a mandatory Basic rate of 12 Mbps on the 5-GHz WLAN and 6 Mbps on the 2.4-GHz WLAN. After the deployment, the customer discovers that the 2.40-GHz frequency band is almost completely unusable and that the 5-GHz frequency is degraded.
Which two options are possible ways to resolve the issues? (Choose two.)
A . Change Channel Width to 20 MHz for the 5-GHz radio.
B . Reduce the number of SSIDs to four or less.
C . Increase the Beacon interval from 100 to 200 ms.
D . Decrease the Beacon interval from 100 to 50 ms.
E . Set the mandatory Basic rate to 18 Mbps on 5 GHz and 24 Mbps on 2.4 GHz for the RF profile.
