Which is the most preferred and secure way of connecting to a WLC GUI to configure a new WLAN?

(A) SSH
(B) HTTP
(C) HTTPS
(D) FTP
(E) None of the above

HTTPS is the correct answer.

You can use either HTTP or HTTPS to access the GUI but the HTTPS method is most preferred because it is far more secure than HTTP as it uses TLS (SSL) to encrypt normal HTTP requests and responses. The only difference between the Hypertext Transfer Protocol (HTTP) and Hypertext transfer protocol secure (HTTPS) protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses. As a result, HTTPS is far more secure than HTTP.
