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