Drag the Huawei ' s wireless positioning solutions on the left to their corresponding features and application scenarios on the right.

Correct Answer:

Explanation:
According to the Huawei documents and resources, the features and application scenarios of the wireless positioning solutions are as follows:
* Wi-Fi terminal positioning: Performs network-side positioning generally based on the RSSI, but provides low positioning accuracy. This method applies to scenarios such as precision marketing and customer flow analysis in shopping malls.
* Bluetooth tag positioning: Runs based on the built-in Bluetooth module of an AP. The AP reports data to a positioning engine for location resolution. This positioning technology provides low positioning accuracy and applies to asset positioning and personnel positioning scenarios.
* UWB positioning: Provides high positioning accuracy, and is applicable to scenarios that require high accuracy, such as intelligent manufacturing, warehousing logistics, and mechanical manufacturing.
* Bluetooth terminal positioning: Runs based on the built-in Bluetooth module of an AP, which can be implemented on either the network side or terminal side.
Therefore, Wi-Fi terminal positioning - 3, Bluetooth tag positioning - 4, UWB positioning - 2, Bluetooth terminal positioning - 1 is the correct answer. References: : https://support.huawei.com/enterprise/en/doc

Which of the following statements about attack defense is true?

• A.Defense against flood attacks can be used to defend against Ping of Death attacks.
• B.Attack defense allows APs to analyze the contents and behaviors of incoming packets on ports to determine whether packets have attack characteristics. The APs then take defense measures on the packets that have attack characteristics.
• C.Attack defense can defend against spoofing packet attacks, malformed packet attacks, fragmentation attacks, and flood attacks.
• D.Fragmentation attack defense enables a device to detect packet fragments in real time and discard or rate-limit them to protect the device.
