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)

A . The load percentage of AP_1 is 40%, and that of AP_2 is 10%.
B. The load balancing mechanism needs to be enabled. Then some STAs are steered from AP_1 to AP_2.
C. If load balancing is performed, the load percentage of AP_1 changes to 30%.
D. The minimum load percentage is 10%, which is greater than the load difference threshold. Therefore, load balancing needs to be enabled.

Answer: A B

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.
