  A. Diffraction
  B. Reflection
  C. Refraction
  D. Diffusion
  E. Scattering
  C. Refraction

• Question 9:

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

  A. Access pointsbroadcast 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 supportedchannels inthe 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 singlechannel forwhich they are programmed. Nearby access points respond on that channel with Probe Response frames. Client stations record information found in the Probe Response frames for use in the association process.
  D. Access points broadcast Beacons on asingle channel for which they are 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 asingle channel for which they are programmed. Nearby client stations listen for Beacon frames and record information found in the Beacons for use in the association process.

• Question 10:

  As XYZ Company's wireless specialist, you have been asked to troubleshoot some unexpected frame patterns in a wireless protocol capture. Your peers explain that the network'sbeacon frames are inconsistent. That is, the BSSID is the same for all beacons, but the source address varies between three different addresses.

  What network configuration would cause this beacon frame behavior?

  A. A single AP supports multiple BSSs withdifferent SSIDs
  B. A virtual cell single channel network has been implemented
  C. The beacons are from an IBSS instead of a BSS
