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 service 1 .
* 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 networks 1 .
* Neighbor MP: Neighboring MP with which an MP prepares to establish a mesh link 1 .
* Candidate MP: AP that directly communicates with a mesh node 2 .

質問 3：
An IPv6 packet consists of three parts. Which of the following is not one of them?
A. IPv6 basic header
B. Upper-layer protocol data unit
C. IPv6 reassembly header
D. IPv6 extension header
正解：C

質問 4：
Smart roaming enables STAs to promptly roam to neighboring APs with better signals, improving the WLAN roaming experience. When the WAC detects a sticky STA. it immediately triggers a smart roaming policy to enable the STA to associate with a better AP.
A. FALSE
B. TRUE
正解：B

質問 5：
Which of the following statements is false about STA roaming tracks on a Huawei WAC?
A. It is unreasonable that the value of Out RSSI is lower than the signal strength of the next associated AP.
B. If the values of In Rx/Tx, In RSSI, Out Rx/Tx, and Out RSSI are low, the signal coverage in this area may be abnormal.
C. It is reasonable that the value of Out Rx/Tx is lower than the signal strength of the next associated AR
D. If the values of In Rx/Tx, In RSSI, Out Rx/Tx, and Out RSSI are good, the signal coverage in this area is excessively dense.
正解：D

質問 6：
