• Question 43:

  What statements about the beamwidth of an RF antenna are true? (Choose two)

  A. The lower the gain of an antenna, the more narrow one or both beamwidths become.
  B. The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.
  C. Horizontal and vertical beamwidth are calculated at the points in which the main lobe decreases power by 3 dB.
  D. Horizontal beamwidth is displayed (in degrees) on the antenna's Azimuth Chart.
  E. Antenna beamwidth is measured in units of decibels relative to an isotropic radiator (dBi).
  C. Horizontal and vertical beamwidth are calculated at the points in which the main lobe decreases power by 3 dB.
  D. Horizontal beamwidth is displayed (in degrees) on the antenna's Azimuth Chart.

• Question 44:

  When performing a site survey for a Multiple Channel Architecture (MCA) system in a multi-tenant building with six floors, what aspect should you, as the site surveyor, keep in mind?

  A. All doors and windows in the building should be open during the site survey to assess maximum coverage range.
  B. The omni-directional antennas of the access points should be oriented parallel to the floor to maximize the coverage pattern across as many floors as possible.
  C. The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.
  D. The Fresnel Zone is completely blocked between floors so each floor is considered a separate site survey.
  C. The channel reuse pattern should be three dimensional with the RF cell extending coverage of each access point to other floors.

• Question 45:

  Given: XYZ Company has decided to install an 802.11 WLAN system that will support 1000 wireless users, but they are concerned about network security. XYZ is interested in deploying standardized security features. In addition to WPA2Enterprise with PEAP and role-based access control, XYZ would like to support management frame protection as well as a fast secure roaming protocol for future mobile handsets.

  As XYZ Company selects a product to deploy, what two IEEE amendments should be supported to provide the management frame protection and fast secure roaming security features? (Choose two)

  A. 802.11j
  B. 802.11p
  C. 802.11r
  D. 802.11u
  E. 802.11w
  F. 802.11z
  C. 802.11r
  E. 802.11w

• Question 46:

  The IEEE 802.11-2007 standard requires ERP capable devices to be backward compatible with devices using which other 802.11 physical layer specifications (PHYs)? (Choose two)

  A. DSSS
  B. FHSS
  C. HR/DSSS
  D. ERP-PBCC
  E. DSSS-OFDM
  A. DSSS
  C. HR/DSSS

• Question 47:

  Given: You are the network administrator for ABC Company. Your manager has recently attended a wireless security seminar. The seminar speaker taught that a wireless network could be hidden from potential intruders if you disabled the broadcasting of the SSID in Beacons and configured the access points not to respond to Probe Request frames that have a null SSID field.

  Your manager suggests implementing these security practices. What response should you give to this suggestion? (Choose two)

  A. Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons and Probe Response frames. This negates any security benefit of trying to hide the SSID in Beacons and Probe Response frames.
  B. This security practice prevents manufacturers' client utilities from detecting the SSID. As a result, the SSID cannot be obtained by attackers, except through social engineering, guessing, or use of a WIPS.
  C. Although it does not benefit the security posture, hiding the SSID in Beacons and Probe Response frames can be helpful for preventing some users (such as guests) from attempting to connect to the corporate network.
  D. Any tenants in the same building using advanced penetration testing tools will be able to obtain the SSID by exploiting WPA EAPOL-Key exchanges. This poses an additional risk of exposing the WPA key.
  E. To improve security by hiding the SSID, the AP and client stations must both be configured to remove the SSID from association request and response frames. Most WLAN products support this.
  A. Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons and Probe Response frames. This negates any security benefit of trying to hide the SSID in Beacons and Probe Response frames.
  C. Although it does not benefit the security posture, hiding the SSID in Beacons and Probe Response frames can be helpful for preventing some users (such as guests) from attempting to connect to the corporate network.
