A network technician is setting up a segmented network that will utilize a separate ISP to provide wireless access to the public area for a company. Which of the following wireless security methods…

A pre-shared key (PSK) provides encryption but offers no individual accountability, as all users share the same key without differentiating their access or actions.

Enterprise (e.g., WPA2/3-Enterprise with 802.1X) provides strong individual accountability via unique user credentials but is typically overly complex and not considered 'basic' for public guest access.

Wi-Fi Protected Setup (WPS) is a simplified method for connecting devices to a wireless network, but it does not provide any form of user accountability or authentication for network access.

A captive portal provides basic accountability for public networks by forcing users to agree to terms of service, provide an email, or log in via a simple mechanism before accessing the internet, allowing for logging of these interactions. This method is specifically designed for public Wi-Fi access where individual credential-based authentication might be too complex or unnecessary but some form of user acknowledgement is desired.
