• Question 31:

  What is the recommended method to protect a wireless outdoor bridge from lightning?

  A. Install the wireless outdoor bridge in a grounded NEMA enclosure.
  B. Install the wireless outdoor bridge inside a building if possible and only have the antenna outside.
  C. Install a fiber-optic link between the wireless outdoor bridge and the antenna.
  D. Install a one-meter segment of fiber-optic cable with a copper-to-fiber-optic transceiver to isolate the wireless outdoor bridge from the network cable plant.
  E. Install a protection frame in the copper portion of the network cable plant to act as a lighting arrestor.
  D. Install a one-meter segment of fiber-optic cable with a copper-to-fiber-optic transceiver to isolate the wireless outdoor bridge from the network cable plant.

• Question 32:

  What are two reasons that it is always preferable to obtain a digital copy of the "as built" drawings for a site you need to perform a WLAN site survey on? (Choose two.)

  A. A digital copy of the "as built" drawings is always more accurate than design drawings because it includes the placement of office furniture.
  B. A digital copy of the "as built" drawings includes all the changes made during construction that are not included in the design drawings.
  C. A digital copy of the "as built" drawings includes a full set of preliminary mechanical drawings so sources of interference, diffusion, and absorption can be easily identified.
  D. A digital copy of the "as built" drawings allows you to more accurately estimate physical AP placement in the customer environment.
  E. A digital copy of the "as built" drawings assists in the placement of WLAN equipment so the WLAN signal minimizes wired network delay.
  B. A digital copy of the "as built" drawings includes all the changes made during construction that are not included in the design drawings.
  D. A digital copy of the "as built" drawings allows you to more accurately estimate physical AP placement in the customer environment.

• Question 35:

  In performing a post-deployment audit, you are concerned by significant changes in measured RSSI and SNR values taken on a wireless client in one location. How do you explain the differences in these values?

  A. The differences in the RSSI and SNR values are a result of signal diffusion in the environment.
  B. The differences in the RSSI and SNR values are a result of multipath in the environment.
  C. The differences in the RSSI and SNR values are a result of signal absorption in the environment.
  D. The differences in the RSSI and SNR values are a result of signal diffraction in the environment.
  B. The differences in the RSSI and SNR values are a result of multipath in the environment.

• Question 36:

  In an outdoor mesh environment, which is the purpose of deploying one of the access points relatively higher than the others?

  A. The MAPs need to be mounted higher than the first hop RAPs so that the mesh units can accomplish radio line of sight.
  B. Elevated MAPs are connected to the switches, providing better bandwidth that all the RAPs utilize for client connectivity.
  C. An AP deployed as a RAP needs to be mounted in a higher elevation to provide clear connectivity to first hop MAPs.
  D. Root APs need clear line of sight to provide the best bandwidth to all of its RAPs, so the higher the better.
  C. An AP deployed as a RAP needs to be mounted in a higher elevation to provide clear connectivity to first hop MAPs.
