Which version type protects unauthorized network access using a setup password?

The correct choice is WPA2 Personal, which is designed to protect networks from unauthorized access by using a pre-shared key or setup password. This password is configured on the router and must be entered by any device attempting to connect to the network. WPA2 Personal utilizes strong encryption to secure the data transmitted over the network, making it a widely used standard for home and small office wireless networks.

WEP, while an older security protocol, is considered weak by modern standards and does not implement a password-based approach in the same secure manner as WPA2. WPA3 builds on the security features of WPA2 and offers additional protections but still requires a similar pre-shared key for personal networks. WPA Enterprise is geared towards large organizations and involves a more complex authentication process using a RADIUS server, thus not using a simple setup password like in WPA2 Personal.
