You have been called upon to add location-based services into an existing controller-based wireless designwhich primarily encompasses handheld devices such as barcode scanners and Cisco 7920 wireless IPphones.
In which mode should you deploy the additional access points to achieve the density required without excessive co-channel interference？（）

You are configuring an RF group of controllers that coordinate Radio Resource Management calculations.
What is the maximum number of WLAN controllers that you can add？（）

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

A Cisco Wireless Location Appliance has been added to track RFID tags placed on laptops being used in aschool. Classrooms at the school have concrete block walls. During testing， you discover that the accuracyof 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 are troubleshooting a problem with a Cisco 7920 wireless IP phone on a standalone WLAN. The phonerings but， when you answer， the call is dropped.
What may have caused this problem？（）

You are troubleshooting a one-way call problem with a Cisco 7920 wireless IP phone on a standaloneWLAN.
What may have caused this problem？（）

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