  When a client moves to a new BSS within an ESS, whatstep is a part of the 802.11 reassociation process?

  A. The client station transmits a Reassociation Request frame to its currentaccess point.

  B. The current access point informs the IP gateway of the reassociation.

  C. The current access point triggers theclient's reassociation service.

  D. The new access point transmits a Reassociation Response to the client station with a status value.

  Correct Answer: D

• Question 27:

  In an 802.11n 2.4 GHz BSS, what prevents eachstation from using the full network bandwidth (e.g. 130 Mbps) for user data throughput when multiple clients are actively exchanging data with the AP? (Choose 2)

  A. Radio receiver hardware cannot process data as quickly as it can be transmitted.

  B. Half of the bandwidth is allocated to uplink traffic and half to downlink traffic.

  C. The DCF and EDCA coordination functions require backoff algorithms

  D. WLAN devices cannot detect collisions and must receive positive frame acknowledgment.

  E. APs do not have sufficient wired connection speeds to the LAN.
