PW0-270 Certified Wireless Analysis Professional (CWAP) Exam Set 5

When a 5 GHz HT station in a 40 MHz BSS desires to protect a 40 MHz transmission from an OFDM station using an RTS/CTS or CTS-to-Self exchange, what frame format is used for the RTS and/or CTS frames?


Options are :

  • HT-greenfield format
  • Dual-CTS
  • Phased Coexistence PPDU
  • Non-HT Duplicate
  • HT-mixed format

Answer : Phased Coexistence PPDU

In the frame decode shown, there are two sets of supported data rates. 1, 2, 5.5, and 11 Mbps are all shown as "basic" data rates, and 6, 9, 12, 18, 24, 36, 48, and 54 Mbps are shown simply as supported data rates. What is true of "basic" data rates in this context?


Options are :

  • The AP requires all client stations to support Basic rates in order to associate to its
  • The highest data rate set to Basic is automatically used to send broadcast traffic such as Beacon frames.
  • Basic rates are only used for multicast traffic, and do not affect unicast traffic
  • Basic rates are defined in an AP's service set to specify mandatory data rates for all retry frames.
  • Basic rates are optional data rates for the ing all WLAN transmissions in the band.
  • The video transmitter is preventing WLAN operation on channel 6, and has only a minor impact on channels 1 and 11.
  • The video transmitter has made no impact on WLAN operation in the band.

Answer : The video transmitter is preventing WLAN operation on channel 6, and has only a minor impact on channels 1 and 11.

As it relates to a spectrum analyzer, complete the following sentence. The ____________ plot always displays the percentage of time (shown on the Y axis) that the overall RF power is a certain specified threshold (of amplitude) above the noise floor for a given frequency range (shown on the X axis).


Options are :

  • Interferer Count
  • FFT Duty Cycle
  • Swept Spectrogram
  • Real-Time FFT

Answer : FFT Duty Cycle

PW0-104 Wireless LAN Administration Practice Exam Set 4

Shown is a screenshot of a wireless protocol analyzer displaying the decode information for a single 802.11 encrypted data + CF-Poll frame. The infrastructure BSS on which this information was captured is using WEP and this particular frame was sent from a client station (STA) to an access point (AP). As a protocol analyst, how would you explain the existence of this frame on the wireless medium given the information in the decode?


Options are :

  • The frame was misinterpreted because of insufficient information received by the analyzer due to frame corruption.
  • The frame was sent by a client station that does not comply with IEEE HR/DSSS standard to an access point that is Wi-Fi certified.
  • The IEEE 802.11 network is using both version 1 and version 2 protocols simultaneously. This unexpected frame is from the version 2 protocol set.
  • The access point is operating as a repeater, and clients must poll repeater access points in order to transmit data frames through them.

Answer : The frame was misinterpreted because of insufficient information received by the analyzer due to frame corruption.

ABC Company is having VoWiFi latency problems on their 802.11g WLAN. A wireless administrator has noticed in the phone's client utilities software that the MAC CRC Error count is higher on stations with problems than on those client stations without problems. A high MAC CRC Error count is attributable to which of the following? (Choose 3)


Options are :

  • High collision rates due to dense population of voice stations and no admission control
  • Two access points with overlapping coverage on a single channel
  • 2.4 GHz ISM band interference from sources such as wireless video cameras and analog phones
  • High multipath conditions due to an RF environment with highly reflective materials

Answer : High collision rates due to dense population of voice stations and no admission control 2.4 GHz ISM band interference from sources such as wireless video cameras and analog phones High multipath conditions due to an RF environment with highly reflective materials
