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.

BSS coloring is a feature introduced in Wi-Fi 6 that assigns different colors to different BSSs to reduce co-channel interference. BSS coloring provides the following advantages:

• Higher packet rate on the air interface: BSS coloring reduces collisions between packets from different BSSs on the same channel, improving packet transmission efficiency.
• More efficient channel use: BSS coloring allows spatial reuse of channels by different BSSs, increasing channel utilization.
• Higher concurrency in high-density scenarios: BSS coloring reduces interference among neighboring APs and improves network performance in high-density scenarios.

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.

According to the Huawei documents and resources, the features and application scenarios of the wireless positioning solutions are as follows:

• Wi-Fi terminal positioning: Performs network-side positioning generally based on the RSSI, but provides low positioning accuracy. This method applies to scenarios such as precision marketing and customer flow analysis in shopping malls.
• Bluetooth tag positioning: Runs based on the built-in Bluetooth module of an AP. The AP reports data to a positioning engine for location resolution. This positioning technology provides low positioning accuracy and applies to asset positioning and personnel positioning scenarios.
• UWB positioning: Provides high positioning accuracy, and is applicable to scenarios that require high accuracy, such as intelligent manufacturing, warehousing logistics, and mechanical manufacturing.
• Bluetooth terminal positioning: Runs based on the built-in Bluetooth module of an AP, which can be implemented on either the network side or terminal side.

Therefore, Wi-Fi terminal positioning - 3, Bluetooth tag positioning - 4, UWB positioning - 2, Bluetooth terminal positioning - 1 is the correct answer.

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.
