• B.1. The MPP periodically broadcasts RANN. 2. The MP receiving the RANN sends a unicast PREQ to the MPP. 3. The MPP replies with a PREP. 4. The route is established between MP and MPP.
• C.1. The MPP periodically broadcasts RANN. 2. The MP receiving the RANN sends a unicast PREP to the MPP. 3. The route is established between MP and MPP.
• D.1. The MP periodically broadcasts PREQ. 2. The MPs/MPPs receiving the PREQ reply with unicast PREP. 3. The route and return route are established between two points.

CAC is implemented in three modes.
Which of the following statements about CAC implementation based on channel usage is FALSE?

• A.If the channel usage reaches the threshold after a new user goes online, an AP will reject access requests of new users, send alarms, but cannot hide its SSID.
• B.When a roaming user attempts to access an AP, the AP checks whether the channel usage reaches the CAC roaming threshold. If so, the AP will reject the access request of the roaming user and send alarms.
• C.An AP periodically detects the channel usage of a radio. Once the channel usage falls below the threshold, the AP sends a clear alarm, allowing new users to go online.
• D.When receiving a new access request, an AP calculates the current channel usage and checks whether the channel usage reaches the threshold. If not, the AP allows the user to go online.

After channel switching without service interruption is configured on an AP, when the AP channel needs to be switched, the AP will notify associated STAs in advance and switch to the new channel with STAs at the same time without interrupting services.

• A.FALSE
• B.TRUE
