A consultant frequently travels and occasionally needs to use their smartphone to provide an internet connection to their laptop. To mitigate security risks, which setup would be the MOST effective when configuring the smartphone's hotspot for secure access?
Restrict the number of devices that can connect to the hotspot to one
Use WPA3 or WPA2 with a strong, unique password for the laptop's connection
Implement MAC address filtering to allow only the laptop's MAC address to connect
Configure the hotspot as an open network to avoid the hassle of passwords
