CompTIA Network+ Practice Test

When deploying a captive portal, clients must complete a specific authentication process before they can access the network. This generally involves interacting with a web page that requires users to enter login credentials, agree to terms of service, or provide some other form of verification. Captive portals are commonly used in public Wi-Fi networks to ensure that users acknowledge rules or gain access by proving their identity.

The other options do not accurately reflect the typical requirements of captive portals. Special software installation is not necessary, as captive portals are designed to work with standard web browsers. Inputting an encryption key is more associated with connecting to secured networks rather than through a captive portal scheme. Reconfiguration of existing connections is also not a standard requirement for accessing a captive portal, as it is designed to function seamlessly with the user's existing network setup.
