Which of the following description about the double link backup is wrong? (Multiple choice)

• A.Dual-link code standby relative to hot standby, after the master CAPWAP tunnel fault is detected, and then establish the backup CAPWAP tunnel business to implement uninterrupted forwarding.
• B.When the AC with the dual-link active/standby configuration coexist with the AC with no dual-link active/standby configuration, the AP preferentially selects the AC with the dual-link active/standby configuration.
• C.Configure the main CAPWAP tunnel establishment process after the dual-link backup function is fully consistent with the common CAPWAP tunnel establishment process
• D.Dual-link hot standby relative to the cold standby, CAPWAP road fault detection is carried out between the active and standby AC, and by the HSB channel real-time synchronization status information.

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

• A.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.
• B.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.STA listens to each channel beacon and finds that AP2 satisfies the roaming condition and sends a probe request to AP2.
• D.AP2 responds by sending a response on channel 6 (the channel used by AP2) after receiving the request in channel 6
