• Question 43:

  Given: To manage increasing enrollment and budget constraints, a school has temporarily parked classroom trailers near the main building on its campus. Students and teachers in the trailers are using desktop computers and have an occasional need to connect to the main building's network for web browsing. The main building has an existing 802.11g Wi-Fi network.

  What would be the most cost-effective and easily-deployable solution to allow the desktop computers in the temporary classrooms to access the main building's network?

  A. Install PCI Wi-Fi cards in all of the desktops and wirelessly connect each computer to the main building's access points.
  B. Install mesh access points in each of the trailers that connect with portal APs in the main building.
  C. Connect the desktop computers in the trailers to the main building by running cables through the existing power conduits
  D. Install wireless workgroup bridges in each trailer through which the wired desktops can connect to the main building's APs.
  D. Install wireless workgroup bridges in each trailer through which the wired desktops can connect to the main building's APs.

  A. Frequency
  B. Speed of light

• Question 45:

  What statement accurately describes an advantage of manual RF site surveys over predictive site surveys?

  A. Manual site surveys are useful for locating and identifying sources of RF interference, while predictive site surveys are not capable of this task.
  B. Manual site surveys are more efficient than predictive site surveys in large facilities because GPS mapping can be used.
  C. Manual site surveys are more accurate than predictive site surveys because they take advantage of complex computer simulations.
  D. Manual site surveys allow the site surveyor to create a static RF environment, whereas predictive site surveys are subject to changes in the RF environment.
  A. Manual site surveys are useful for locating and identifying sources of RF interference, while predictive site surveys are not capable of this task.
