Fingerprint-based positioning technology is a method that uses the signal strength or phase difference of wireless signals to locate objects. There are two types of fingerprint-based positioning technology: virtual fingerprint-based positioning and real fingerprint-based positioning. In virtual fingerprint-based positioning, the positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information. In real fingerprint-based positioning, the fingerprint map is obtained through onsite information collection.

iMaster NCE-CampusInsight analyzes network issues during correlation analysis of poor-QoE clients, including coverage, interference, throughput, and hardware issues. It also provides suggestions for network optimization based on the analysis results.

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.

FF02::18C is an IPv6 multicast address. An IPv6 multicast address starts with FF and identifies a group of interfaces that belong to the same multicast group. The other options are not IPv6 multicast addresses. 2222::11 is an IPv6 unicast address, FE80::A is an IPv6 link-local address, and FC00::1 is an IPv6 unique local address.

The device ESN (Electronic Serial Number) is a unique identifier that is used by the CloudCampus cloud management platform to determine the tenant to which a device belongs. The device ESN is bound to a tenant when a device is added to the platform.

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.

Smart roaming is not a roaming optimization solution, but a feature that allows an AP to automatically adjust its transmit power based on signal strength and interference level. The other options are all roaming optimization solutions that can reduce roaming latency and packet loss.

The WPA3 transition mode applies to both WPA3-Enterprise and WPA3-Personal. In this mode, WPA3 and WPA2 can coexist for a period of time in the future to enable WPA3-incapable STAs to access a WPA3-configured network.

In Huawei’s smart roaming solution, the WAC can discover and maintain neighboring AP entries of STAs by using two methods: passive listening and active scanning. Passive listening means that the AP listens to the Probe frames sent by STAs and reports them to the WAC. Active scanning means that the AP periodically and proactively scans neighboring APs of STAs and reports them to the WAC.

C is false because the license file only affects the number of devices that can be managed by iMaster NCE-CampusInsight, not the data display.

E is false because the UTC time of devices does not need to be consistent with that of iMaster NCE-CampusInsight.
