What is the primary function of a captive portal in a network environment?
To allocate IP addresses to devices connected to the network
To encrypt data packets on a wireless network using WPA2
To increase the range of the wireless signal
To authenticate and redirect users to a login page before they gain access to the network
A captive portal controls network access by requiring users to view or interact with a web page before Internet access is granted. It's a common method for implementing guest Wi-Fi networks, ensuring users accept legal terms or log in. Other answers might sound plausible, but they do not correctly describe the primary function of a captive portal.
