• Question 5:

  Given:

  As a consultant, you have been hired by ABC Company to implement an outdoor WLAN connection between two buildings that are 2 kilometers (1.24 miles) from each other, with no obstructions in between.

  Your first required objective is to create a point-to-point link between the two buildings within the local regulatory body's 800 mW EIRP maximum.

  Your second required objective is to provide an industry-standard security solution capable of supporting mutual authentication.

  As an optional objective, you must minimize the amount of interference from, and to, nearby WLAN networks.

  You install an OFDM wireless bridge at each building, configuring one in root mode and the other in non- root mode. You set each radio for 100 mW (20 dBm) and attach 9 dBi omni-directional antennas to both. You configure the network for

  WPA2-Enterprise with PEAPv0/EAP-MSCHAPv2 authentication.

  Which statement is true about the solution you chose to deploy?

  A. Your solution meets both required objectives and the optional objective.
  B. Your solution meets the first required objective and the optional objective, but not the second objective.
  C. Your solution meets the second required objective and the optional objective, but not the first required objective.
  D. Your solution meets neither required objective but meets the optional objective.
  E. Your solution meets both required objectives, but does not meet the optional objective.
  F. Your solution does not meet either required objective, or the optional objective.
  E. Your solution meets both required objectives, but does not meet the optional objective.

• Question 6:

  When replacing the antenna of a WLAN device with a similar antenna type that has a higher passive gain, what antenna characteristic will decrease?

  A. Beamwidth
  B. Range
  C. Active gain
  D. Receive sensitivity
  E. Fresnel Zone size
  A. Beamwidth

• Question 7:

  What problems may occur when there are hidden nodes in the BSS?

  A. Increase in downlink (transmitted by AP) frame retries

  C. Use of frame fragmentation with fragment bursts
  D. Excessive use of null data frames
  E. Duration values vary widely in each data frame
  B. High retransmission count for a subset of client stations

• Question 8:
