Example Questions

Which three device types are identified by Cisco Spectrum Expert Wi-Fi finding an Avg Pulse Duration parameter? Which antenna generally has the narrowest first Fresnel zone in both the horizontal and vertical planes? Which format can NOT be imported into Cisco WCS Planning Tool? What is the term for the space that exists above a drop ceiling or below a raised floor and that is used for air return? Which three items should the site survey documentation include? (Choose three) Which two Cisco antennas provide better isolation from RF sources that might be located behind the antennas? Under U.S. regulatory domain, which channel plan delivers the proper coverage in a large lecture hall that requires four access points? Which two methods can be used to prevent or reduce RFI from colocated directional antennas? (Choose two) What is the minimum recommended access point overlap for voice roaming? A design requires 100 access points with high channel bandwidth and disabled lower data rates. How are the data rates set on the Cisco WLC and Cisco WCS? In which three frequency bands does the Cisco Spectrum Expert Wi-Fi tool perform spectrum analysis? (Choose three) Which statement regarding the site-survey process is correct? What does a broad-spectrum interferer lower? In an outdoor bridge link, what is calculated by using this formula: transmitter power + antenna gain - insertion OR cable loss? When using WMM Call Admission Control, what are the default bandwidth values for video on 802.11a/n? Which statement about active and passive surveys is incorrect? To provide efficient roaming between the cells, which percent of cell overlap is recommended for 2.4 GHz and 5 GHz access points? How many access points will a Cisco 7600 Series Router with six installed Cisco Catalyst 6500 Series Wireless Services Modules support? What does a Cisco Unified Wireless IP Phone 7921G deployment require? How is attenuation measured? What will cause wireless voice devices to perform poorly? If there is an existing 802.11g WLAN at a site, which service can be provided without conducting a new site survey? Which three items does the Cisco WCS Planning Tool Generate Proposal Report provide? (Choose three) When planning for VoWLAN capacity during a site survey, how many simultaneous calls can be estimated per 5 GHz channel? When using a lightning arrestor, connect which type of ground wire to a good earth ground? Which value is NOT supported by Cisco Spectrum Expert, when checking for RF coverage? What approximates the signal attenuation of a plasterboard wall? When conducting a wireless voice site survey, which two sizing considerations exist for the coverage cell? (Choose two) How should the transmit power on an access point and client each be set during a site survey? Which statement is true when using a Cisco Wireless Mesh Networking Solution? To which parameter should the access point be set during a site survey? According to the following statement, can you tell me which term is described? It is the air return for an air conditioned system. In most buildings, the area above a drop ceiling or under a raised floor is used as the air return (source of air) for the air conditioning. Those drop ceiling and raised floors are also where wire is often installed. If wire and cable is installed in a drop ceiling or raised floor, it is out of sight. If that cable were burning, it would give off toxic fumes. These would be fed to the rest of the building by the air conditioner. As a result, people could be injured even though they are a long way from the fire. After the site installation is complete, you should verify the mobility of the VoWLAN device while walking the site on an active phone call. Which Cisco WLC or Cisco WCS command is most beneficial in determining roaming efficiency? What statement best describes Cisco WCS support for antennas? When surveying for VoWLAN, which power level should you base the access point coverage design on? Construction of a new automobile parts manufacturing facility has recently been completed. The facility IT manager wants to deploy voice over WLAN. During your initial walkthrough, you observe numerous highly reflective surfaces on the manufacturing equipment and in the building construction itself. What potential problem exists that should be accounted for during your site survey? What are two objectives of a pre-site survey walkthrough? (Choose two) By how much is a signal's strength reduced when the signal passes through an object that introduces 3 dB of attenuation? Cisco recommends a decibel referenced to 1 milliwatt signal level for the coverage cell edge at the predetermined data rate that is needed to support the VoWLAN device and call capacity requirements. What is that signal level value for Cisco Unified Wireless IP Phones 7920, 7921G, and 7925G? When planning for voice deployments with the Cisco Unified Wireless IP Phone 7921G handset in a multifloor building with a WLAN that operates at an 11 MB/s data rate, how many decibels referenced to 1 milliwatt of same-channel separation are recommended between floors? Which Cisco access point should be used for a customer site that requests hardware to support Maximal Ratio Combining indoors? Which class of Cisco access points operate under IEEE 802.3af power? Which can NOT be selected for supported services in Cisco WCS Planning Tool? For an active Cisco Unified Wireless IP Phone 7921G 5 GHz site survey, what are the most appropriate client test settings to use with the AirMagnet site survey tool? The AirMagnet passive site survey tool can provide RF coverage data, except for which parameter? Which is NOT part of a typical wireless site survey? Where should known problem areas in the site survey be documented? What should be done if Cisco Spectrum Expert Wi-Fi reports a channel utilization of 40 percent on channel 36, from a source outside of the site? What is a site survey best practice for location-based services?
