  A. HR/DSSS (802.11b)
  B. OFDM (802.11a)
  C. ERP (802.11g)
  D. HT (802.11n)
  E. CCK (802.11b)
  F. PBCC (802.11g)
  C. ERP (802.11g)

• Question 104:

  In an 802.11n 2.4 GHz BSS, what prevents each station from using the full network bandwidth (e.g. 130 Mbps) when multiple clients are actively exchanging data with the AP? (Choose two)

  A. Radio receiver hardware cannot process data as quickly as it can be transmitted.
  B. Half of the bandwidth is allocated to uplink traffic and half to downlink traffic.
  C. The DCF and EDCA coordination functions require backoff algorithms
  D. WLAN devices cannot detect collisions and must receive positive frame acknowledgment.
  E. WLANs rely on the CSMA/CD protocol and must wait a collision detection period after each frame is transmitted.
  C. The DCF and EDCA coordination functions require backoff algorithms
  D. WLAN devices cannot detect collisions and must receive positive frame acknowledgment.

• Question 105:

  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.

• Question 106:

  What item is essential for performing a manual RF site survey for a warehouse facility?

  B. I-Beam mounting kits for hanging temporary access points
  C. High-gain omni antennas for APs mounted high on warehouse ceilings
  D. Predictive site survey software that supports directional antennas
  E. NEMA enclosures that protect APs used for the survey
  A. A facility map with an explanation of applications used in each area

• Question 107:
