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 2：
Which of the following statements about attack defense is true?
A. 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.
B. Attack defense can defend against spoofing packet attacks, malformed packet attacks, fragmentation attacks, and flood attacks.
C. Defense against flood attacks can be used to defend against Ping of Death 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.

質問 4：
As shown in the figure, STA_1 through STA_4 are associated with AP_1, and STA_5 is associated with AP_2. Assuming that the load balancing threshold is 2, the load difference threshold is 25%, and API and AP2 support a maximum of 10 STAs, which of the following statements are true? (Select All that Apply)

A. The load balancing mechanism needs to be enabled. Then some STAs are steered from AP_1 to AP__2.
B. The minimum load percentage is 10%, which is greater than the load difference threshold. Therefore, load balancing needs to be enabled.
C. The load percentage of AP_1 is 40%, and that of AP_2 is 10%.
D. If load balancing is performed, the load percentage of AP_1 changes to 30%.

質問 5：
Differentiated network planning needs to be performed to meet requirements of different IoT services in Huawei's CloudCampus loT solutions. Drag the solutions on the left to their corresponding network planning suggestions on the right.

正解：

Explanation
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. 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.
