What is the minimum recommended access point overlap for voice roaming？（）

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

What should be done if Cisco Spectrum Expert Wi-Fi reports a channel utilization of 40 percent onchannel 36， from a source outside of the site？（）

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

After the site installation is complete， you should verify the mobility of the VoWLAN device whilewalking the site on an active phone call. Which Cisco WLC or Cisco WCS command is mostbeneficial in determining roaming efficiency？（）

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？（）

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.

Which three items does the Cisco WCS Planning Tool Generate Proposal Report provide？（）
