So what are the correct options for the following configuration description? (Multiple choice)
A. Specify the threshold value of 25dB for quickly forcing users to go offline based on the signal-to- noise ratio
B. By default, the function of quickly forcing weak signal users to go offline is enabled.
C. When the terminal signal strength is lower than -25dBm, the terminal is forced to go offline directly
D. When the signal-to-noise ratio threshold is configured too large, it may cause the terminal to go offline frequently
正解：A,D

質問 2：
Which of the following descriptions about dynamic load balancing used in high-density scenarios is correct? (Multiple choice)
A. Load balancing is applicable to high-density wireless network environments to effectively ensure the reasonable access of STAs. The purpose of 5G priority access within four APs is to reduce the 2.4CHz load and improve the overall performance of the system.
B. APs with load balancing enabled must be connected to the same AC, and STAs can scan the SSIDs of APs that perform load balancing.
C. Dynamic load balancing can be divided based on the number of users, traffic, and business type.
D. Load balancing between APs, load balancing based on the number of access users or traffic, optimizes the distribution of terminals in the entire network and improves user experience
正解：A,B,C,D
