QUESTION 25
As shown in the figure, STA_1 through STA_4 are associated with AP_1, and STA_5 is associated with AP_2. Assuming that the load balancing threshold is 2, the load difference threshold is 25%, and API and AP2 support a maximum of 10 STAs, which of the following statements are true? (Select All that Apply)

The load percentage of AP_1 is 40%, and that of AP_2 is 10%.

The load balancing mechanism needs to be enabled. Then some STAs are steered from AP_1 to AP__2.

If load balancing is performed, the load percentage of AP_1 changes to 30%.

The minimum load percentage is 10%, which is greater than the load difference threshold. Therefore, load balancing needs to be enabled.

Explanation
The load percentage of an AP is calculated by dividing the number of associated STAs by the maximum number of STAs supported by the AP. In this case, the load percentage of AP_1 is 4/10 = 40%, and that of AP_2 is 1/10 = 10%. The load balancing mechanism needs to be enabled to balance the load between AP_1 and AP_2. Then some STAs are steered from AP_1 to AP_2 based on the load balancing threshold and the load difference threshold.

QUESTION 27
Drag the reasons for AP onboarding failures on the left to the corresponding troubleshooting operations on the right.

Explanation
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. References: :
https://support.huawei.com/enterprise/en/doc/EDOC1100158948/9a0d5c37/ap-onboarding-failures
