PW0-071 Certified Wireless Technology Specialist Sales Exam Set 3

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)


Options are :

  • 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.
  • 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.
  • 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.
  • 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.

Answer : 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. 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.

ABC Company has a 2.4 and 5 GHz WLAN deployment supporting four bands in the 5 GHz range (UNII 1, UNII 2, UNII 2e, and UNII 3). DFS functionality is enabled as required by the regulatory domain. Band steering is also enabled to encourage dual-band clients to use frequency bands with more capacity.Your performance analysis shows that many dual-band VoWiFi client devices will move back and forth between 2.4 and 5 GHz as the user roams throughout the building. All APs have 2.4 and 5 GHz radios enabled.This "band hopping" behavior is viewed by network staff to be undesirable. What is the most likely cause of the unpredictable client band selection behavior?


Options are :

  • 5 GHz frequencies offer better RF penetration than 2.4 GHz, but 2.4 GHz offers more voice call capacity and lower latency than 5 GHz.
  • The voice client does not support DFS, and therefore experiences some 5 GHz coverage holes as it moves through the network.
  • Interference from 5 GHz radar sources has increased frame corruption and retries on channels 36-48 in UNII 1.
  • The client's band selection algorithm prefers 5 GHz, but band steering behavior usually steers 75-85% of client devices to 2.4 GHz.

Answer : The voice client does not support DFS, and therefore experiences some 5 GHz coverage holes as it moves through the network.
