  D. 24
  B. 12

• Question 172:

  The following description of the steps for Layer 2 roaming is wrong?

  A. The STA listens to each channel beacon and finds that AP2 satisfies the roaming condition and sends a probe request to AP2.
  B. AP2 responds by sending a response on channel 6 after receiving the request in channel 6 (the channel used by AP2)
  C. The STA sends the 802.11 disassociation information to the AP1 through the channel 6 (the channel used by the AP2), and the association between the user and the AP1 is released.
  D. The STA sends an association request to AP2 through channel 6, and AP2 responds with the association response to establish an association between the user and AP2.
  C. The STA sends the 802.11 disassociation information to the AP1 through the channel 6 (the channel used by the AP2), and the association between the user and the AP1 is released.
