Pass the Huawei HCIE-WLAN H12-351_V1.0 Questions and answers with CertsForce

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.

The device ESN (Electronic Serial Number) is a unique identifier that is used by the CloudCampus cloud management platform to determine the tenant to which a device belongs. The device ESN is bound to a tenant when a device is added to the platform.

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.

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.

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.

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.

C is not a tool commonly used for WLAN network planning, acceptance, or health evaluation. eDesk is a tool for remote fault diagnosis and rectification on WLAN networks.

In DHCPv6 stateful autoconfiguration, a client obtains an IPv6 address, a PD prefix (if required), and other configuration parameters (such as DNS server address) from a DHCPv6 server.

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.

According to the Huawei documents and resources, the troubleshooting operations for the AP onboarding failures are as follows:

APS fail to be authenticated by the WAC: Whitelist the APS. The WAC can authenticate APs based on their MAC addresses or SNs. If an AP is not whitelisted on the WAC, it cannot be authenticated and onboarded.

License resources on the WAC are insufficient: Expand the license capacity. The WAC can manage a limited number of APs based on its license. If the license resources are insufficient, some APs cannot be onboarded.

APS fail to obtain IP addresses: Check the DHCP server. The APs need to obtain IP addresses from a DHCP server before they can communicate with the WAC. If the DHCP server is not configured or reachable, the APs cannot obtain IP addresses and onboard.

APS fail to ping the WAC: Check the network between the WAC and APS. The APs need to ping the WAC to discover its IP address and establish a CAPWAP tunnel. If there is a network problem between the WAC and APs, such as incorrect VLAN configuration or firewall blocking, the APs cannot ping the WAC and onboard.

Therefore, APS fail to be authenticated by the WAC - c, License resources on the WAC are insufficient - b, APS fail to obtain IP addresses - d, APS fail to ping the WAC - a is the correct answer.
