CWNA-108 practice questions, page 2 of 3, with answer review and explanations.

Question 6

What wireless networking term describes the increase of RF energy in an intentional direction with the use of an antenna?

  1. Directed Radiation
  2. Beam Digression
  3. Passive Gain
  4. Active Amplification

Question 7

Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?

  1. Dipole and yagi
  2. Grid and sector
  3. Patch and panel
  4. Dish and grid

Question 8

What statement about the beamwidth of an RF antenna is true?

  1. Horizontal and vertical beamwidth are calculated at the points where the main lobe decreases power by 3 dB.
  2. The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.
  3. When antenna gain is lower, the beamwidth is also lower in both the horizontal and vertical dimensions.
  4. Vertical beamwidth is displayed (in degrees) on the antenna's Azimuth chart.

Question 9

Which one of the following is not a factor considered when calculating the Link Budget for an outdoor point-to-point WLAN bridge link?

  1. Operating frequency
  2. MU-MIMO capabilities of the bridges
  3. Receive antenna gain
  4. Transmit power

Question 10

What best describes WPA2 in relation to 802.11 wireless networks?

  1. WPA2 is the standard that defines security for WLANs.
  2. WPA2 is a certification created by the Wi-Fi Alliance that validates devices correctly implement CCMP/AES.
  3. WPA2 is the second version of WPA and it enhances security through the use of TKIP instead of WEP.
  4. WPA2 is specified in the 802.11 standard as implementing CCMP/AES.
