An engineer is optimizing the wireless network. In order to prevent non-critical services from occupying too much network resources, he turns on the QoS function based on the application protocol. The current network has completed the wireless network deployment, and the data forwarding method of wireless users is tunnel forwarding. Then, on which of the following devices should the QoS function based on the application protocol be deployed?
- A . AP directly connected to the upper switch
- B . AP
- C . User gateway equipment
- D . WAC
In VRRP hot standby networking, in order to simplify the command line configuration of the standby WAC, you can enable the wireless configuration synchronization function. Through the wireless configuration synchronization function, the active VAC can use the HSB active-standby channel to synchronize the public wireless configuration to the standby WAC.
- A . True
- B . False
When HSB is synchronizing data, in order to further ensure that the table entries on the primary and backup devices are completely consistent, the backup device will check whether its existing session table entries are consistent with the primary device every 20 minutes. If they are inconsistent, the session table entries on the primary device will be synchronized to the backup device.
- A . True
- B . False
