By default, on the WLAN controller for a voice application using Cisco 7921 wireless IP phones, what is the percentage of RF bandwidth that can be dedicated to the phones? What is the recommended distance between controller-based access points for support of roaming? A Cisco 4404 WLAN controller is being connected to a Cisco 6500 Catalyst Series Switch. How would you interconnect and configure LAG for connectivity and ensure redundancy? What is the maximum number of WLAN controllers that can join a single mobility group? Which set of RF characteristics is directly monitored by CiscoWorks WLSE? Cisco WCS version 4.0 is supported on which operating system? Which Cisco Aironet Series devices can be powered using 802.3af inline power? What is the maximum number of wireless controllers that the highest-end Cisco WCS server can manage? In order for a controller-based access point to be allowed to participate in aggressive load balancing, it must have heard the client within how many seconds? Which parameter, when enabled on a standalone access point, gives the highest priority to a voice packet even when QoS is not enabled? A Cisco Wireless Location Appliance has been added to track RFID tags placed on laptops being used 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? What is the maximum number of hexadecimal characters allowed when configuring the WPA or WPA2 passphrase in Cisco ADU? You are charged with implementing a secure wireless installation which will provide Internet access to client devices but will not allow communications between wireless clients. In addition to implementing PSPF or peer-to-peer blocking on the wireless side, which of the following actions should you perform on the wired infrastructure? On a WLAN controller, what is the default limit on the number of entries in the database that will be used for local authentication? You have very few Cisco 7920 wireless IP phones on your network, but lots of wireless laptops. You want to increase the bandwidth available for the laptops by decreasing the bandwidth reserved for the Cisco 7920 phones. What is the lowest percentage of voice-allocated bandwidth you can select on the WLAN controller? When configuring QoS on a wireless controller, the per-user, real-time bandwidth contract is enforced for which of the following protocols? Your customer has deployed a Cisco Wireless Location Appliance within its warehouse environment. However, employees there have been experiencing problems when tracking objects using active RFID tags. The RFID beacon rate is 10 seconds and you have discovered an issue with the RFID timeout value.Where and how should the RFID value be changed? You are installing a Cisco Aironet 1000 Series controller-based access point. When you boot it, all the LEDs on the access point blink together. What does this indicate about the access point? When configuring a Cisco 3845 Integrated Services Router to support 802.11b and g clients, which of the following commands would be correct? You review the Failed Attempts logs on an AAA server and find: "unknown network access server error." Which failure could produce this error? 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 Cisco 7920 wireless IP phones. In which mode should you deploy the additional access points to achieve the density required without excessive co-channel interference? Which Cisco Aironet Series has a built-in digital thermometer designed to protect the radio? You are trying to change the polling parameters used by the location manager via the Cisco WCS, and your request is being denied. What is wrong? Which of the following commands on the wireless interface of a Cisco 3845 Integrated Services Router allows the SSID to broadcast? On a Cisco Aironet 1130AG Series standalone access point, the status LED is dark blue and blinking. What does this indicate? You are troubleshooting a problem with a Cisco 7920 wireless IP phone on a standalone WLAN. The phone rings but, when you answer, the call is dropped. What may have caused this problem? Which protocol does the RADIUS server use inside the secure tunnel of EAP-FAST to authenticate the client when one-time passwords are in use? How many RADIUS servers can be added to a controller and thereafter assigned to the authentication or accounting of individual WLAN IDs? To implement EAP-FAST authentication on the Cisco Secure ACS server, which of the following parameters are required? When configuring Cisco Secure ACS to support wireless EAP authentication, which device must be configured as a AAA client? A mobility group is created by a Cisco WLCM and 4402 Series Wireless LAN Controller. A client that is anchored on the Cisco WLCM roams to an access point on the 4402 controller. You then run a debug command on the 4402 controller. Which message would best describe the establishment of the tunnel from the foreign controller's perspective? When assigning a standalone access point a non-root role, which two parameters, other than Role in the radio network settings, must be configured on the SSID Manager page? (Choose two.) Which of the following parameter sets must be configured on the Cisco Wireless Location Appliance? A client roams from H-REAP AP1 to H-REAP AP2. The client is unable to associate to H-REAP AP2. H-REAP AP2 has six other clients associated to it, which continue to pass traffic. What has caused this problem? You are troubleshooting a one-way call problem with a Cisco 7920 wireless IP phone on a standalone WLAN. What may have caused this problem? Which of these statements is true about SSIDs configured in Cisco ADU? A Cisco WCS version 4.0 has been installed on a server with a dual Pentium 3.0 GHz processor, 4 GB RAM, and an 80 GB hard drive. A location appliance has been incorporated into the network and is being monitored by the Cisco WCS. There are 3000 devices to be tracked but not all of them are being tracked on the Cisco WCS. What can be done to correct the problem? You are configuring a wireless LAN controller for QoS. Which 802.11e user priority tag should you apply to voice applications? One of your customers has decided to deploy location-based services in addition to existing wireless services. The customer requires that the additional access points to be deployed in monitor-only mode. The most likely reason for this requirement is that the customer has which of these existing wireless devices? A mobility group is created by a Cisco WLCM and 4402 Series Wireless LAN Controller. A client that is anchored on the 4402 controller roams to an access point on the Cisco WLCM. You then run a debug command on the 4402 controller. Which message would best describe the establishment of the tunnel from the anchor's perspective? On a Cisco Aironet 802.11 a/b/g wireless LAN client adapter, the status LED and activity LED are alternating on and off. What does this indicate? Which of the following statements explains why it is normally best to have more than one controller-based access point participate in the containment of one rogue access point? On a Cisco Aironet 1240AG Series standalone access point, the radio LED is dark blue and blinking, but the status LED and Ethernet LED are both off. What does this indicate?
