CWNP PW0-100 Online Questions & Answers

• Question 121:

  During the discovery and connectivity process, client and AP stations exchange information about their supported data rates. After the association, how do client and AP stations select the supported data rate that will be used to send an

  802.11 data frame?

  A. During the association, the client and AP agree to use the same transmit rate, but either station can request a change at any time after the association.
  B. The client and AP each choose the optimal data rate to use independently of one another, based on their own experience of the RF link.
  C. The client and AP may use different transmit rates, but the AP determines the data rate that will be used by each client station in the BSS.
  D. The client and AP may use different transmit rates, but the client determines the data rate that it will use and the data rate that the AP will use when communicating to the client.
  E. The client and AP may use a different transmit rates, but the transmit rate is determined by the peer station, based on the peer's experience of the RF link.
  B. The client and AP each choose the optimal data rate to use independently of one another, based on their own experience of the RF link.

• Question 122:

  Given: Two co-located 802.11b/g/n APs can interfere with one another and cause contention and collisions, even when the two APs are operating on non-overlapping channels (e.g. 1 and 6).

  What deployment flaw could cause this problem? (Choose two)

  A. The access points are mounted too closely to one another.
  B. Reflective objects in the area are causing significant multipath.
  C. A client station is using active scanning to probe for access points on multiple channels.
  D. The output power on the access points is too high.
  E. A client station authenticates to both access points, but does not associate.
  F. The access points are not synchronized to the same NTP server.
  A. The access points are mounted too closely to one another.
  D. The output power on the access points is too high.

• Question 123:

  In an infrastructure Basic Service Set (BSS), how does the passive scanning process occur?

  A. 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.
  B. 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.
  C. Client stations broadcast Probe Request frames on the single channel for which they are programmed. Nearby access points respond on that channel with Probe Response frames. Clientstations record information found in the Probe Response frames for use in the association process.
  D. 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.
  D. 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.

• Question 124:

  The client devices that connect to your network include a mix of dual-band 802.11n, single-band 802.11b/ g, and some 802.11a/g. Your access points are configured with the same SSID on both the 2.4 and 5 GHz bands. The APs are also configured to prioritize client connectivity to 5 GHz. How does an AP perform band steering to encourage clients to use 5 GHz?

  A. When the client sends a probe request in the 2.4 GHz band, the AP may reply with information about the 5 GHz BSS.
  B. The AP may ignore the initial probe requests or 802.11 authentication requests sent in the 2.4 GHz band by dual-band clients
  C. The AP may allow an 802.11 association with the client in the 2.4 GHz band, then send unicast channel switch announcements to the client announcing the 5 GHz channel as the new channel.
  D. After receiving probe request frames from the same client in both bands, the AP may send an association request frame to the client in the 5 GHz band.
  E. The AP may allow an 802.11 association with the client in the 2.4 GHz band, then the AP may perform a transparent client handoff by transferring the client's MAC address to the 5 GHz radio.
  B. The AP may ignore the initial probe requests or 802.11 authentication requests sent in the 2.4 GHz band by dual-band clients

• Question 125:

  What factors will have the most significant affect on the amount of wireless bandwidth available to each station within a BSS? (Choose two)

  A. The number of client stations associated to the BSS
  B. The power management settings in the access point's beacons
  C. The presence of co-located (10m away) access points on non-overlapping channels
  D. The data rates at which nearby client stations are transmitting and receiving data
  E. The layer 3 protocol used by each station to transmit data over the wireless link
  A. The number of client stations associated to the BSS
  D. The data rates at which nearby client stations are transmitting and receiving data
