2 QUESTION: 172 Which tool can best provide throughput verification? A. WLC > Monitor > Clients > LinkTest B. WaveDeploy C. InSSIDer D. Xirrus Wi-Fi Inspector QUESTION: 173 After you have run the VoWLAN Voice Readiness Tool in WCS 7.0, you see there are potential problem areas in your facility. Which two actions will help you troubleshoot these coverage areas? (Choose two.) A. Verify the green, yellow, and red regions in the RF environment only if the floor has not been calibrated. B. To prevent one-way audio, set the AP power levels to half the power of the client. This will ensure proper radio coverage. C. You need to edit the RSSI values for Cisco IP Phones so the b/g/n radios display the region map properly. D. Determine if the coverage area will have enough APs to support the VoWLAN client, since all APs must have a Tx power level that does not exceed that of the client. E. Set the AP power level to match the VoWLAN client to avoid one-way audio. Answer: D, E QUESTION: 174 What is the attenuation of a wireless signal that passes through a cider block wall? A. 3 db B. 4 db C. 6 db D. 12 db QUESTION: 175

3 When using WCS 7.0 to calibrate a floor, is it more important to collect 50 or more distinct locations or to collect 150+ measurements? A measurements are more important than the locations because the information gathered is more granular. B. Collecting 50 or more distinct locations is more important because this provides a wider coverage across the floor being calibrated. C. Depending on the size of the floor 50+ distinct locations and 150+ measurements may provide divergent information that requires more data collection. D. When calibrating a floor 50 or more distinct locations will yield 150+ measurements because multiple measurements are collected at each distinct location. Answer: D QUESTION: 176 Given an AP that can transmit at 100 mw and the client at 40 mw, which power setting should be used for a site survey? A. 10 mw B. 20 mw C. 40 mw D. 60 mw E. 80 mw F. 100 mw QUESTION: 177 What is the minimum CCX version necessary on a client when adding data points during WCS Calibration? A. CCXv1 B. CCXv2 C. CCXv3 D. CCXv4 E. CCXv5 QUESTION: 178

4 Which three basic pieces of information will you need to perform a WLAN site survey? (Choose three.) A. How many customer user interviews will be required? B.

6 What is the most likely cause of MAP1 association to MAP2 instead of directly to the RAP? A. Incorrect BGN B. Default BGN C. SNR D. Absorption and scattering caused by weather conditions. E. Incorrect radio configuration Answer: C QUESTION: 184 Which wireless tool would be most useful in planning a WLAN solution prior to performing a site survey? A. Ekahau Survey B. Air Magnet Survey C. Air Magnet Wi-Fi Analyzer D. Cisco Spectrum Expert E. Cisco WCS Answer: E QUESTION: 185 After installation of a new data-only wireless network, an engineer found that RRM has set all of the APs to a power level of 1. Which option describes the reason for this? A. APs are too far apart for the set data rates. B. EDRRM is enabled. C. APs should be manually set initially. D. TPC needs to be enabled.

7 E. DTPC value is set too high. F. High co-channel interference exists. Answer: A QUESTION: 186 A customer has requested site surveys for data, voice, video, and location services for their location. The customer will be using RFID tags extensively. Which type of site survey should be conducted? A. data B. voice C. video D. location-based services E. bridging F. multi-survey Answer: D QUESTION: 187 A customer wants to deploy wireless services inside a 500-seat auditorium. Given the volume of potential users in this condensed area, what is the best option for AP deployment? A. place n APs along the outside edge with dual-band directional antennas B. place n APs along the outside edge with 2.4GHz directional antennas C. place n APs along the outside edge with 5GHz directional antennas D. place n APs in the center with 2.4GHz sector antennas E. place n APs in the center with 5GHz sector antennas F. place n APs in the center with dual-band sector antennas QUESTION: 188 An outdoor mesh network is being designed with one RAP and then a single RF hop to MAP1 and another single RF hop from MAP1 to MAP2 to extend coverage. Given that the initial RF backhaul at the RAP is operating at 24 Mb/s, what is the expected RF backhaul bandwidth at MAP2? A. 24 Mb/s B. 20 Mb/s

8 C. 14 Mb/s D. 7 Mb/s E. 3 Mb/s F. 1 Mb/s Answer: C QUESTION: 189 Refer to the exhibit. Which type of interference would the engineer detect on the Cisco Spectrum Expert? A. Bluetooth B. Wi-Max C.

The access radio has to connect to two or several points. B. The access cell usually covers more area at ground level that may have more sources of reflection and interference. C. The access cell radio range is larger than the backhaul radio range, which causes the backhaul cell radio to suffer from more interference. D. Backhaul radios are a bottleneck for throughput. E. RAPs help MAPs avoid coverage holes., D QUESTION: 192 DRAG DROP Answer: QUESTION: 193
