PW0-105 Certified Wireless Network Administrator Exam Set 4

What statement about the IEEE 802.11e QoS facility is true?


Options are :

  • 802.11 QoS is achieved by giving high priority queues a statistical advantage at winning contention.
  • To improve efficiency, Block Acknowledgments are required for Voice and Video WMM queues.
  • When the Voice queue has frames awaiting transmission, no data will be transmitted from the Best Effort queue.
  • Four 802.1p user priorities are mapped to eight 802.11 transmit queues.

Answer : 802.11 QoS is achieved by giving high priority queues a statistical advantage at winning contention.

Given: You are being interviewed by ABC Company for employment as a wireless site survey engineer. The interviewing manager asks you what items should be included in a manual RF site survey report.What answer would be accurate? (Choose two)


Options are :

  • Itemized list of equipment, licenses, and support contracts required for the facility
  • Documentation noting physical security hazards in the RF coverage area
  • Documentation noting where each access point will be placed and how it will be mounted
  • RF heat map illustrating coverage and signal quality for each frequency band

Answer : Documentation noting where each access point will be placed and how it will be mounted RF heat map illustrating coverage and signal quality for each frequency band

If an 802.11 RF transmission reaches a receiving antenna simultaneously by direct and indirect (reflected) paths, what effect will the reel with Probe Response frames. Clientstations record information found in the Probe Response frames for use in the association process.
  • Access points broadcast Beacons on a single channel for which it is programmed. Nearby client stations listen for Beacon frames and record information found in the Beacons for use in the association process.
  • Access points broadcast Beacons on all channels of each radio within the regulatory domain. Nearby client stations record information found in the Beacons for use in the association process.
  • Client stations broadcast Probe Request frames on all supported channels in the regulatory domain. Nearby access points respond with Probe Response frames. Client stations record information in the Probe Response frames for use in the association process.
  • Answer : Access points broadcast Beacons on a single channel for which it is programmed. Nearby client stations listen for Beacon frames and record information found in the Beacons for use in the association process.

    Which data rate is supported by 802.11g radios that is not supported by 802.11a radios?


    Options are :

    • 12 Mbps
    • 9 Mbps
    • 11 Mbps
    • 54 Mbps

    Answer : 11 Mbps

    When a client station sends a broadcast probe request frame with a wildcard SSID, how do APs respond?


    Options are :

    • For each probe request frame, only one AP may reply with a probe response.
    • Each AP sends its own ACK, and then follows the ACK with a probe response.
    • After waiting a SIFS, all APs reply at the same time with a probe response.
    • After waiting a SIFS, a designated AP sends an ACK, and then replies with a probe response.
    • Each AP responds in turn after preparing a probe response and winning contention.

    Answer : Each AP responds in turn after preparing a probe response and winning contention.

    Given:A WLAN transmitter that emits a 200 mW signal is connected to a cable with 3 dB loss.If the cable is connected to an antenna with 10 dBi gain, what is the EIRP at the antenna element?


    Options are :

    • 10 dBm
    • 13 dBm
    • 26 dBm
    • 30 dBm
    • 20 dBm

    Answer : 30 dBm
