A small business owner wants to offer free Wi-Fi to customers in the lobby but is concerned that guests could reach the company's internal file server and point-of-sale system. Which configuration BEST addresses this concern?

Accepted Answer

Enable a guest network (separate SSID and VLAN) that isolates guest traffic from the internal network

Change the internal Wi-Fi password weekly and share it with customers

Answer
