Huawei HCIE-WLAN (Written) V1.0 H12-351_V1.0 Exam Dumps: Updated Questions & Answers (October 2025)

Radio calibration is applicable to high-density scenarios where a large number of users access the network simultaneously and require high bandwidth, such as stadiums, exhibition halls, and conference centers. Radio calibration can improve user experience by increasing the frequency bandwidth for high-load APs.

The home agent is a device that communicates with the gateway on the STAs’ home network at Layer 3 and maintains the binding entries of STAs’ home addresses and care-of addresses. A home WAC can function as a home agent of STAs, while a home AP cannot.

After multicast-to-unicast conversion is enabled on an AP’s air interface, the destination MAC address of multicast packets sent over the air interface is changed to the MAC address of a STA that has joined the multicast group. This improves the transmission efficiency and reliability of multicast packets.

The display sync-configuration compare command is used to check whether the public configurations on two WACs are consistent after wireless configuration synchronization. The command output shows the differences between the configurations on the master and backup WACs. In this case, the configuration of vap-profile name 3 exists on the master WAC but not on the backup WAC.

 IPsec uses authentication headers (AHs) and encapsulating security payloads (ESPs) to ensure secure transmission of service data on the network. AHs provide authentication and integrity verification for the sender and the receiver, while ESPs provide encryption and optional authentication for the data.

According to the Huawei documents and resources, EAP termination and EAP relay are typical 802.1X authentication modes between the access device and authentication server. In EAP termination mode, the access device terminates EAP packets and encapsulates them into RADIUS packets. In EAP relay mode, the access device directly encapsulates the received EAP packets into RADIUS using EAP over RADIUS (EAPoR) packets2. Therefore, A and B are the correct answers.

Fingerprint-based positioning technology is a method that uses the signal strength or phase difference of wireless signals to locate objects. There are two types of fingerprint-based positioning technology: virtual fingerprint-based positioning and real fingerprint-based positioning. In virtual fingerprint-based positioning, the positioning engine generates a virtual fingerprint library through calculations based on the AP deployment and environment information. In real fingerprint-based positioning, the fingerprint map is obtained through onsite information collection.

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

According to the Huawei documents and resources, the encapsulation formats used for EAP termination in 802.1X authentication are as follows:

B. EAPoL: The client and access device exchange information using EAPoL packets across the LAN2.

C. EAPoR: The access device directly encapsulates the received EAP packets into RADIUS using EAP over RADIUS (EAPoR) packets2.

Therefore, B and C are the correct answers. References: 2: https://support.huawei.com/enterprise/en/doc/EDOC1100086527

A. 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. This statement is false because in EAP termination mode, an access device extracts information from EAP packets, encapsulates the information into RADIUS packets, and sends the RADIUS packets to an authentication server2.

D. 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. This statement is false because it describes the EAP relay mode, not the EAP termination mode2.

Therefore, A and D are the correct answers. References: 2: https://support.huawei.com/enterprise/en/doc/EDOC1100086527
