• Question 96:

  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.

  A. Beamwidth

• Question 99:

  If an 802.11 RF transmission reaches a receiving antenna simultaneously by direct and indirect (reflected) paths, what effect will the reflected signal have on the signal that took the direct line-of- sight path?

  A. The direct signal will only be received if the reflected signal is more than 180 degrees out of phase.
  B. The direct signal cannot be received if the indirect signal is less than 90 degrees out-of-phase.
  C. The signals will be distorted if the indirect signal arrives simultaneously at the receiver, but 90 degrees out-of-phase.
  D. If the signals are in-phase, they will combine together, cancel one another out, and create a null.
  C. The signals will be distorted if the indirect signal arrives simultaneously at the receiver, but 90 degrees out-of-phase.
