Question #7
Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?
  1. A
    Dish and grid
  2. B
    Dipole and yagi
  3. C
    Grid and sector
  4. D
    Patch and panel

Correct Answer:
B

Question #8
What statement about the beamwidth of an RF antenna is true?
  1. A
    Horizontal and vertical beamwidth are calculated at the point where the main lobe decreases power by 3 dB.
  2. B
    Vertical beamwidth is displayed (in degrees) on the antenna’s Azimuth chart.
  3. C
    When antenna gain is lower, the beamwidth is also lower in both the horizontal and vertical dimensions.
  4. D
    The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.

Correct Answer:
A

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. A
    MU-MIMO capabilities of the bridges
  2. B
    Receive antenna gain
  3. C
    Transmit power
  4. D
    Operating frequency

Correct Answer:
A

Question #10
What best describes WPA2 in relation to 802.11 wireless networks?
  1. A
    WPA2 is specified in the 802.11 standard as implementing CCMP/AES.
  2. B
    WPA2 is the standard that defines security for WLANs.
  3. C
    WPA2 is a certification created by the Wi-Fi Alliance that validates devices correctly implement CCMP/AES.
  4. D
    WPA2 is the second version of WPA and it enhances security through the use of TKIP instead of WEP.

Correct Answer:
B
