A mesh connection can be torn down by either of the two APs that have established it by sending a

Mesh Peering Close frame to the other AP. This frame indicates that the sender no longer wants to

maintain the mesh connection.

Navi WAC networking is a networking mode that uses a WLAN Access Controller (WAC) to manage

and control APs. It can provide different authentication and security policies for different user

groups, such as employees and guests. Guest data is isolated from the internal network to prevent

security threats.

Radio calibration is applicable to high-density scenarios where a large number of users access the

network simultaneously and require high bandwidth, such as stadiums, exhibition halls, and

conference centers. Radio calibration can improve user experience by increasing the frequency

bandwidth for high-load APs.

Customer Requirement Specification (CRS) is a document that needs to be output after the project

requirements are clarified. The CRS describes the customer’s requirements in detail and serves as the

basis for subsequent project design and delivery.

After multicast-to-unicast conversion is enabled on an AP’s air interface, the destination MAC

address of multicast packets sent over the air interface is changed to the MAC address of a STA that

has joined the multicast group. This improves the transmission efficiency and reliability of multicast

packets.

According to the Huawei documents and resources, Huawei Agile Cloud Authentication (HACA)

supports iMaster NCE-Campus as well as Agile Controller-Campus as the HACA server. HACA is an

authentication method that allows users to access a network without entering user names or

passwords3. Therefore,

B

is

the

correct

answer.

In a dual-link HSB scenario, after an AP sets up CAPWAP links with the active and standby WACs, the

AP periodically sends Echo packets to the WACs to detect link status. The Echo packets are sent every

30 seconds by default.

Huawei’s CloudCampus Solution supports three user access authentication modes: 802.1X

authentication, MAC address authentication, and Portal authentication.

The load percentage of an AP is calculated by dividing the number of associated STAs by the

maximum number of STAs supported by the AP. In this case, the load percentage of AP_1 is 4/10 =

40%, and that of AP_2 is 1/10 = 10%. The load balancing mechanism needs to be enabled to balance

the load between AP_1 and AP_2. Then some STAs are steered from AP_1 to AP_2 based on the load

balancing threshold and the load difference threshold.

According to the Huawei documents and resources, the network planning suggestions for the

solutions are as follows:

Asset management: The RFID signal coverage distance is 25 m. Therefore, RFID signal coverage must

be considered during AP deployment planning. Attach RFID tags on the surface or top of assets to

prevent signals from being blocked.

ESL: Shelves may be blocked in application scenarios. Therefore, shelf blocking must be considered

during network planning. The shelves can be deployed in aisles to minimize obstacles toward

integrated base stations.

Smart healthcare: For applications that support regional positioning, positioning devices need to be

deployed at key entrances and exits based on service requirements.

Therefore, Asset management - 2, ESL - 1, Smart healthcare - 3 is the correct answer. Reference: :
