The Purpose of the ip http server command on a switch

C.

The "ip http server" command is used to enable the HTTP server for the switch. This allows users to access the switch using a web browser. Once enabled, users can access the switch by entering its IP address in a web browser.

Option A is incorrect because enabling the HTTPS server is done using the "ip http secure-server" command, not "ip http server." HTTPS provides secure communication between the web browser and the switch, using SSL or TLS encryption.

Option B is incorrect because enabling dot1x authentication is done using the "dot1x system-auth-control" command. Dot1x is a port-based authentication protocol that provides network access control (NAC) to prevent unauthorized devices from accessing the network.

Option C is incorrect because enabling MAB (MAC Authentication Bypass) authentication is done using the "authentication mac-move permit" command. MAB authentication allows devices to authenticate using their MAC address, bypassing the need for username and password credentials.

Option D is incorrect because enabling web authentication redirection is done using the "authentication login" command. Web authentication redirection allows users to be redirected to a web page where they can enter their username and password to authenticate before accessing the network.

In summary, the "ip http server" command enables the HTTP server on the switch, allowing users to access the switch using a web browser.
