Huawei H12-351_V1.0 問題集

質問 1：
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 2：
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

質問 3：
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：
Which of the following statements about WLAN roaming and signal strength Is false?
A. In most cases, the signal strength of a STA should range from -45 dBm to -65 dBm.
B. STAs can roam between WACs in dual-link HSB mode.
C. Generally, a STA roams when it detects that the signal strength is less than -75 dBm.
D. Smart roaming can be enabled on the WAC to help ST As roam and associate with APs with better signals.
正解：C

質問 6：
Which of the following statements about VXLAN is false?
A. Layer 2 and Layer 3 VXLAN gateways must maintain VBDIF interfaces. Otherwise, users cannot communicate with each other through these interfaces.
B. A VBDIF interface is a logical interface created based on a BD. It is similar to a VLANIF interface on a traditional network.
C. A Layer 2 VXLAN gateway forwards traffic to a VXLAN network and can also be used for Intra-subnet communication on the same VXLAN network.
D. A Layer 3 VXLAN gateway is used for inter-subnet communication on a VXLAN network and communication with external non-VXLAN networks.
正解：A
