• Question 91:

  What WLAN system feature is required to produce a scenario with the following configuration on a single access point? (Choose 2)

  1.

  SSID = Guest / BSSID = AA:AA:AA:AA:AA:AA /

  D. Access Categories
  E. User-based authentication
  F. Dual-radio AP hardware
  G. Integrated DHCP server
  A. Multiple WLAN Profiles
  E. User-based authentication

• Question 92:

  Given:

  ABC Company performs top-secret government contract work and has recently purchased an 802.11 Wireless Intrusion Prevention System (WIPS) to enforce their "NO WIRELESS" network security policy.

  What attack type cannot be recognized by the WIPS?

  A. Deauthentication
  B. MAC Spoofing
  C. Protocol Jamming
  D. Eavesdropping
  E. RF Jamming
  D. Eavesdropping

• Question 93:

  What can cause an excessively high VSWR (Voltage Standing Wave Ratio) in a WLAN RF transmission line?

  A. An impedance mismatch in the RF cables and connectors
  B. Reflected direct current (DC) voltage on the main RF signal line
  C. Attenuation of the RF signal as it travels along the main signal path
  D. Crosstalk (inductance) between adjacent RF conductors
  A. An impedance mismatch in the RF cables and connectors

• Question 94:

  What component of the 802.11 standard allows stations to reserve access to the RF medium for a specified period of time?

  A. Long slot times
  B. DTIM Interval
  C. Listen Interval
  D. Probe Request frames
  E. RTS or CTS frames
  E. RTS or CTS frames

• Question 95:

  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 96:

  What term describes the effect of increasing the intensity of an RF wave with an antenna by focusing the energy in a specific direction?

  A. Spatial Multiplexing
  B. Active Amplification
  C. Beam Compression
  D. Passive Gain
  E. Isotropic Radiation
  D. Passive Gain

• Question 97:

  What statement about 802.11 WLAN performance is true?

  A. Use of larger frame sizes results in greater throughput in low interference environments.
  B. BSS support for 65 KB A-MPDUs will increase the maximum data rate available to client devices.
  C. In 802.11n, changing the security mechanism from WPA2-Personal to WPA2-Enterprise will enable the HT MCS rates.
  D. Compared to an Independent BSS, an Infrastructure BSS can provide almost twice the throughput between wireless nodes.
  E. Use of short guard intervals improves reliability and throughput in high multipath environments
  A. Use of larger frame sizes results in greater throughput in low interference environments.
