Which three items should the site survey documentation include？（）

For an active Cisco Unified Wireless IP Phone 7921G 5 GHz site survey， what are the mostappropriate client test settings to use with the AirMagnet site survey tool？（）

In which three frequency bands does the Cisco Spectrum Expert Wi-Fi tool perform spectrumanalysis？ （）

Which class of Cisco access points operate under IEEE 802.3af power？（）

What does a Cisco Unified Wireless IP Phone 7921G deployment require（）？

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 orunder a raised floor is used as the air return （source of air） for the air conditioning. Those dropceiling and raised floors are also where wire is often installed. If wire and cable is installed in a dropceiling 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 beinjured even though they are a long way from the fire.

When planning for voice deployments with the Cisco Unified Wireless IP Phone 7921G handset in amultifloor building with a WLAN that operates at an 11 MB/s data rate， how many decibelsreferenced to 1 milliwatt of same-channel separation are recommended between floors？（）

Which two Cisco antennas provide better isolation from RF sources that might be located behindthe antennas？（）

What will cause wireless voice devices to perform poorly？（）

The Cisco Aironet 1140 Series Access Point draws 12.95 W at the power source. However， whenusing a long Ethernet cable， the device can draw up to how much additional wattage？（）
