質問 4：
The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The user indicate that they need more throughput and all stations are 5 GHz capable 802.11ac clients. The current AP configuration uses 20 MHz channels in both

A. Use a 160 MHz channel on the 5 GHz radio
B. Use a 40 MHz channel on the 5 GHz radio
C. Install a second AP in the coverage area
D. Use a 40 MHz channel on the 2.4 GHz radio.
正解：C
