Huawei H12-351_V1.0 問題集

質問 1：
In mesh networking, APs have different roles. Drag the AP roles on the left to the role descriptions on the right.

正解：

Explanation
MP: Mesh node that uses IEEE 802.11 MAC and PHY protocols for wireless communication. This node supports automatic topology discovery, automatic route discovery, and data packet forwarding. It can provide both mesh service and user access service1.
MPP: MP node that connects a WMN to MPs on other types of networks. This node can function as a portal for communication between internal mesh nodes and external networks1.
Neighbor MP: Neighboring MP with which an MP prepares to establish a mesh link1.
Candidate MP: AP that directly communicates with a mesh node2.

質問 5：
Drag the Huawei's wireless positioning solutions on the left to their corresponding features and application scenarios on the right.

正解：

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: :

質問 6：
Which of the following statements about EAP relay and EAP termination are false? (Select All that apply)
A. In EAP relay mode, an access device extracts information from EAP packets, encapsulates the information into RADIUS packets, and sends the RADIUS packets to an authentication server.
B. The EAP termination mode simplifies the processing on an access device and supports various authentication methods. However, this mode requires an authentication server to support EAP and have high processing capability.
C. In EAP termination mode, an access device encapsulates EAP packets sent by an 802. IX client Into RADIUS packets, without processing the data in the EAP packets.
D. In EAP termination mode, an access device extracts client authentication information from the EAP packets sent by a client and encapsulates the information using the standard RADIUS protocol. The access device supports only the EAP MD5-Challenge authentication method.
正解：B,C
