You are configuring a Cisco WLC in a hotel that provides wireless guest access to the Internet,
using web authentication. Guest credentials are generated for individual rooms upon check-in.
Users often complain about certificate security warnings when opening their browser. You need to
fix this issue so that the clients stop getting this certificate warning every time they access the
Web-Authentication page, but still protect the credentials during the authentication handshake of
this guest setup. You cannot configure the user devices yourself. What is the best solution that
meets these requirements?

A.
Disable HTTPS on the WLC to avoid the certificate warning during the web authentication.

B.
Configure the WLAN with an EAP method that does not use PKI certificates, but still protects
the credentials during the authentication handshake.

C.
Remove the self-signed SSL certificate of the WLC or make sure that the clients know about
the WLC CA that generated this self-signed certificate.

D.
Install a third-party SSL certificate on the WLC, issued by a known public CA.
