H12-351_V1.0 Exam Dumps - Huawei Certification Questions and Answers

iMaster NCE-CampusInsight analyzes network issues during correlation analysis of poor-QoE clients, including coverage, interference, throughput, and hardware issues. It also provides suggestions for network optimization based on the analysis results.

Navi WAC networking is a networking mode that uses a WLAN Access Controller (WAC) to manage and control APs. It can provide different authentication and security policies for different user groups, such as employees and guests. Guest data is isolated from the internal network to prevent security threats.

In a dual-link backup scenario, when the active link recovers, the AP waits for 15 Echo intervals before switching back to the original primary WAC. This prevents frequent link switchovers caused by unstable links.

According to the Huawei documents and resources, the chronological order during the 802.11r fast roaming process between WACs is as follows:

2.The STA accesses the network through API. This is the initial association process before roaming.

1.The STA initiates an 802.11 FT authentication request to AP2. This is the first step of the roaming process when the STA moves to a new AP.

3.AP2 starts the reassociation timer, and sends an 802.11 FT authentication response to the STA. This is the second step of the roaming process when AP2 responds to the STA’s request and sets a timer for reassociation.

4.The STA generates and installs a P TK based on the information contained in the response frame. This is the third step of the roaming process when the STA derives a new pairwise key for encryption.

5.The STA sends a reassociation request to AP2. This is the fourth step of the roaming process when the STA requests to reassociate with AP2.

6.AP2 generates and installs a PTK according to PMK-RI and information contained in the request frame. This is the fifth step of the roaming process when AP2 derives the same pairwise key as the STA.

7.After receiving the reassociation request, AP2 disables the reassociation timer, and then sends a reassociation reg onse to the STA. This is the sixth step of the roaming process when AP2 confirms the reassociation with the STA and stops the timer.

8.The STA receives the response frame of AP2. The roaming process is complete. This is the final step of the roaming process when the STA completes the handover to AP2.

Therefore, 2, 1, 3, 4, 5, 6, 7, 8 is the correct answer. References: https://support.huawei.com/enterprise/en/doc/EDOC1100169459/8d79210e/configuring-wireless-mesh-networking
