• Question 32:

  Given: XYZ Corporation is experiencing connectivity problems with their existing building-to-building bridge link. A concrete wall on the roof of one building is partially blocking the Fresnel Zone, and the connection is dropping many frames. The administrator moves the antenna to an area not obstructed by the concrete wall and then realizes the RF cable cannot reach the new location.

  If an extension cable is added to move the antenna, what are the likely results?

  A. The data throughput rate will increase because VSWR will decrease.
  B. The Equivalent Isotropically Radiated Power (EIRP) will decrease.
  C. The antenna's azimuth beamwidth will decrease.
  D. The size of the Fresnel zone will increase.
  E. The likelihood of a direct lightning strike will increase.
  B. The Equivalent Isotropically Radiated Power (EIRP) will decrease.

• Question 33:

  When compared with legacy Power Save mode, how does WMM-PS improve voice device and application performance?

  A. WMM-PS identifies and prioritizes incoming VoIP data and delivers it immediately
  B. WMM-PS uses a trigger-and-delivery method that eliminates the need for PS-Poll exchanges
  C. WMM-PS requires scheduled service periods for predictable uplink data delivery.
  D. WMM-PS allows the WLAN transceiver to disable more components when in a low power state.
  B. WMM-PS uses a trigger-and-delivery method that eliminates the need for PS-Poll exchanges

• Question 34:

  What specifications should be evaluated for an antenna before it is implemented in a WLAN system? (Choose three)
