Which of the following descriptions about HSB is correct? (Multiple choice)
- A . HSB backup can be divided into real-time backup, batch backup, and scheduled backup.
- B . The HSB jumper between the active and standby ACs is used to synchronize AP status, user information, and DHCP address pool information
- C . The default heartbeat period of the HSB channel is 1 ∗ 3s, so the default service interruption time is 3s
- D . HSB heartbeat time and cycle can be modified on AC
In order to expand the wireless coverage area and reduce the cost of wired deployment, an enterprise adopts Mesh networking architecture to deploy WLAN network.
After the deployment is complete, the engineer runs the display mesh whitelist-profile all command, which displays the following information.
Which of the following descriptions of this network is wrong?
- A . The Mesh whitelist template "test" is referenced twice
- B . Users need to add the physical MAC addresses of neighboring APs that are allowed to access in the Mesh whitelist template.
- C . The Mesh whitelist template "default" is not referenced
- D . By default, the system has created a Mesh whitelist template named "default"
In some areas, the radar system works on the 5G channel and there is interference with the AP radio frequency signal working on the same channel. When the AP detects that there is interference in the frequency band of its working channel, it can automatically switch the working channel through the () function.
In an N+1 backup scenario, the switchover between the primary and backup WACs is determined by the AP. By default, if the AP does not receive a CAPWAP heartbeat detection message from the primary WAC within how many seconds, the primary and backup switchover will be triggered?
- A . 180
- B . 150
- C . 90
- D . 75
In a certain WLAN network, load balancing, intelligent roaming and spectrum navigation functions are deployed on the radio frequency. The engineer then configures the Mesh service on the radio frequency. This will cause the Mesh service to fail to take effect.
- A . True
- B . False
As shown in the figure, in the dual-link load-sharing hot standby network, AP1 is a newly launched AP, and both WACs have the configuration to access this AP. Which of the following WACs will AP1 access first?
- A . WAC1
- B . No access
- C . WAC2
- D . Random Access
In a WLAN network, which of the following typical obstacles has the correct order of signal attenuation values from small to large?
- A . Ordinary glass window <12 cm brick wall <metal wall <24 cm brick wall
- B . 12cm brick wall < 24cm brick wall < metal wall < ordinary glass window
- C . 12cm brick wall < 24cm brick wall < ordinary glass window < metal wall
- D . Ordinary glass window <12 cm brick wall <24 cm brick wall <metal wall
In WLAN network, there are four transmission systems: SISO, MISO, SIMO and MIMO. Which of the four transmission systems can transmit two signals at the same time?
- A . SIMO
- B . SIso
- C . MISO
- D . MIMO
In the WLAN network WAC roaming scenario, the roaming group server is mainly used to maintain the member table of the roaming group and send it to each WAC in the roaming group, so that the WACs in the roaming group can recognize each other and establish tunnels between WACs.
Which of the following descriptions about roaming group servers are correct? (Multiple choice)
- A . A WAC that becomes a roaming server can join multiple roaming groups at the same time
- B . A WAC can serve as a roaming server for multiple roaming groups at the same time
- C . The roaming group server can be a WAC outside the roaming group
- D . A WAC that becomes a roaming server cannot be managed by other roaming servers
In a WLAN network, if a user is associated with the same WAC before and after roaming, it can be regarded as a special case of inter-WAC roaming, that is, the HAC and FAC overlap.
- A . True
- B . False
