A company has multiple APs in its WLAN network, which are centrally managed by a WAC. To facilitate users to access the wireless network, the company sets the SSID of the APs to the same name, but some APs will have a high load. In view of the above scenario, the company can use the load balancing function to balance the load of APs in the WLAN network and fully guarantee the bandwidth of each user.
- A . True
- B . False
Redundant radio frequencies in WLAN networks will cause co-channel interference and waste network capacity.
Therefore, which of the following processing strategies does Huawei wireless controller support for redundant radios? (Multiple choice)
- A . Switch the Yushe RF to monitor mode
- B . Keep the remaining radios silent (do not send messages)
- C . Switch the redundant radio to the 5G radio
- D . Turn off redundant radio
Which of the following challenges are faced in wireless coverage in high-density WLAN scenarios? (Multiple choice)
- A . There are many user terminals and the types are concentrated
- B . High concurrency rate and serious interference within the system
- C . Complex scenarios and limited equipment installation
- D . The wall structure is complex and the wall penetration loss is large
In the WAC high-reliability networking mode, which of the following is correct when sorting the active/standby switching speed from fast to slow?
- A . N+1 backup > VRRP hot backup > dual-link hot backup / dual-link cold backup
- B . VRRP hot backup > dual-link hot backup/dual-link cold backup > N+1 backup
- C . VRRP hot backup > N+1 backup > dual-link hot backup/dual-link cold backup
- D . Dual-link hot backup/dual-link cold backup > VRRP hot backup > N+1 backup
In WLAN network planning, the final signal field strength is proportional to the AP transmission power and gain, and inversely proportional to the path loss and signal attenuation.
- A . True
- B . False
A company has deployed a WLAN network. In order to prevent too many users from fiercely occupying the wireless channel, the company has configured user CAC. The specific configuration of the RRN template is as follows. Which of the following descriptions of the configuration is wrong? 
- A . The threshold for the number of new users is 32
- B . When the number of online users reaches 40, the AP begins to reject access requests from other new users.
- C . The user number threshold for roaming users is 40
- D . The signal threshold for prohibiting weak signal terminals from accessing is 25dB
The AP calculator in CloudCampus APP integrates various scenarios and network construction standards. Which of the following scenarios is not included?
- A . Gaomi venues
- B . Hotel
- C . Mine
- D . Shopping mall
During the STA access process, a link authentication phase is required. During this phase, which of the following security policies supports the shared key authentication mechanism?
- A . WAPI
- B . WFA3
- C . WEP
- D . WPA2
Directional antennas have strong signal strength gain in the horizontal and vertical lobes, but no signal outside the lobe range. Therefore, it is recommended to use high-gain directional antennas to increase the coverage distance of outdoor APs.
- A . True
- B . False
Which of the following descriptions of WLAN network capacity optimization methods are correct? (Multiple choice)
- A . For scenarios where AP coverage overlaps, configure the load balancing function to guide some terminals to migrate to APs with relatively light loads.
- B . Configure the device and the terminal to communicate using the Wi-Fi 6 protocol to increase the terminal rate
- C . When the currently deployed APs cannot meet the capacity requirements, the number of APs can be increased.
- D . Limit user rates while ensuring user experience and ensure network availability for most users
