Which statement accurately describes configuration of Data and Management ports on the ClearPass appliance?

The Management port (ethernet 0) provides access for cluster administration and appliance maintenance using the WebUI, CLI, or internal cluster communication. This configuration is mandatory.

The configuration of the data port is optional. If this port is not configured, requests are redirected to the Management port.
