A Cisco WCS version 4.0 has been installed on a server with a dual Pentium 3.0 GHz processor， 4GB RAM， and an 80 GB hard drive. A location appliance has been incorporated into the network and isbeing monitored by the Cisco WCS. There are 3000 devices to be tracked but not all of them are beingtracked on the Cisco WCS.
What can be done to correct the problem？（）

You are troubleshooting a problem with a Cisco 7920 wireless IP phone that is causing the phoneto drop calls. The problem appears to be a roaming bandwidth issue. In order to verify what kindof issue it is， you decide to increase the bandwidth reserved for roaming on the WLAN controllerto the maximum.
What level do you set the bandwidth to？（）

Using the WLSE， you are trying to push out a configuration job to a standalone access point， butthe job does not start.
Which of the following would cause this failure？（）

You are using ADU and are authenticated and associated to an access point. However， you areunable to obtain an IP address.
Which of these has caused this problem？（）

A Cisco Wireless Location Appliance has been added to track RFID tags placed on laptops beingused in a school. Classrooms at the school have concrete block walls. During testing，you discover that the accuracy of the system needs to be improved.You decide to edit the map in the Cisco WCS to add the interior walls.
How many interior walls can you add to improve the accuracy of the location appliance？（）

You have been called upon to add location-based services into an existing controller-based
wireless design which primarily encompasses handheld devices such as barcode scanners and Cisco7920 wireless IP phones.
In which mode should you deploy the additional access points to achievethe density required without excessive co-channel interference？（）

A Cisco Aironet 1020 controller-based access point has been connected to a Catalyst 3550-24 PWRSwitch. However， when it is powered up， the access point fails.
What has caused this problem？（）
