Which of the following statements is false about weak-signal coverage evaluation on Campuslnsight?

• A.Collect signal strength statistics of access clients on each AP. If the majority of access clients on an AP suffer from weak signal strength for a long period, a weak-coverage issue is detected.
• B.Display the overview and distribution of APs affected by weak-signal coverage issues, including the number of affected APs and clients.
• C.Through client journey playback, you can check whether a weak-signal coverage issue occurs when a client connects to an AP.
• D.Choose Issue Analysis > Weak-Signal Coverage > Original Issue List to view information about all APs affected by weak-signal coverage issues in the current time window.

Drag the short-range wireless IoT technologies on the left to their corresponding descriptions on the right.

Correct Answer:

Explanation:
According to the Huawei documents and resources, the definitions of the short-range wireless IoT technologies are as follows:
* ZigBee: IEEE 802.15.4-based wireless communication technology is a short-range, and low-power wireless communication technology that supports star, mesh, and hybrid networking.
* Bluetooth: With the emergence of IoT industries such as smart wearables, smart home, and Internet of Vehicles, short-range communication technologies are attracting more and more developers.
* REID: Its basic principle is to automatically identify objects based on the transmission characteristics of radio signals and space coupling (inductance or electromagnetic coupling) or radar reflection.
* Wi-Fi: Wireless networking technology based on IEEE 802.11 is the most popular WLAN technology.
Therefore, ZigBee - 1, Bluetooth - 3, REID - 2, Wi-Fi - 4 is the correct answer. References: : https://support.
