Huawei H12-351_V1.0 HCIE-WLAN (Written) V1.0 Exam Practice Test

B is false because only Layer 3 VXLAN gateways need to maintain VBDIF interfaces for inter-subnet communication on a VXLAN network or communication with external non-VXLAN networks. Layer 2 VXLAN gateways do not need VBDIF interfaces.

According to the Huawei documents and resources, Huawei Agile Cloud Authentication (HACA) supports iMaster NCE-Campus as well as Agile Controller-Campus as the HACA server. HACA is an authentication method that allows users to access a network without entering user names or passwords3. Therefore, B is the correct answer.

A mesh connection can be torn down by either of the two APs that have established it by sending a Mesh Peering Close frame to the other AP. This frame indicates that the sender no longer wants to maintain the mesh connection.

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.

The WPA3 transition mode applies to both WPA3-Enterprise and WPA3-Personal. In this mode, WPA3 and WPA2 can coexist for a period of time in the future to enable WPA3-incapable STAs to access a WPA3-configured network.

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.

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.

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.

• 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.

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.

According to the Huawei documents and resources, the VRRP preemption delay is the time that an AC waits before preempting another AC with a lower priority. If the VRRP preemption delay is set to a small value, the following problems may occur after a master/backup switchover:

• B. A master/backup switchback is triggered too quickly. If the master AC recovers soon after a switchover, it may preempt the backup AC again and become the master AC. This may cause frequent switchovers and affect network stability1.
• C. Backup information is incomplete. If the backup AC takes over services from the master AC too quickly, it may not have received all the data synchronized from the master AC through HSB. This may cause service interruption or data loss2.

Therefore, B and C are the correct answers. References: 1: https://support.huawei.com/enterprise/en/doc/EDOC1100064368/80fc2ebd/example-for-configuring-vrrp-hsb  2: https://support.huawei.com/enterprise/en/doc/EDOC1100096325/1a753937/vrrp-hsb-configuration

A router is not included in a typical RFID system. A typical RFID system consists of three components: RFID tag, RFID reader, and information processing platform. The RFID tag is attached to the object to be identified, the RFID reader communicates with the tag and reads its information, and the information processing platform processes and stores the data collected by the reader.

Broadcast address is not an IPv6 address type. IPv6 does not support broadcast addressing, but uses multicast addressing instead. The other options are valid IPv6 address types. Unicast address identifies a single interface, multicast address identifies a group of interfaces, and anycast address identifies multiple interfaces but delivers packets to only one of them.

FF02::18C is an IPv6 multicast address. An IPv6 multicast address starts with FF and identifies a group of interfaces that belong to the same multicast group. The other options are not IPv6 multicast addresses. 2222::11 is an IPv6 unicast address, FE80::A is an IPv6 link-local address, and FC00::1 is an IPv6 unique local address.

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. References: 2: https://support.huawei.com/enterprise/en/doc/EDOC1100086527

C is false because the license file only affects the number of devices that can be managed by iMaster NCE-CampusInsight, not the data display.

E is false because the UTC time of devices does not need to be consistent with that of iMaster NCE-CampusInsight.
