An engineer wants to configure guest access to redirect to a webpage and log in with provided credentials. Which configuration option on the WLAN is selected?

The 'Authentication' option under Web Policy on a Cisco WLC WLAN enables web authentication, which intercepts HTTP traffic and redirects the client to a credential login page. The supplied credentials are verified against a local or external database before access is granted. This is the standard guest access model that combines a web redirect with mandatory credential-based login.

Passthrough redirects clients to a web page but grants network access without requiring any credential entry.

Conditional web redirect triggers after a successful 802.1X or web authentication event to forward the client to a specific URL, not to prompt for initial login credentials.

Splash page web redirect presents a notification or acceptance page but does not require the client to enter credentials before access is granted.

A preauthentication ACL defines which traffic is permitted before authentication occurs and is not a mechanism for redirecting users to a login page.
