An administrator manipulated the subnet mask but was still unable to access the user interface. How must the administrator access the appliance to perform the initial configuration?

Explanation

When the subnet mask has been misconfigured, the appliance becomes unreachable over the network, making GUI or SSH access via any data or management port impossible. The serial or console port provides out-of-band, direct physical access to the appliance that is independent of IP configuration, allowing an administrator to log in and correct the network settings during initial configuration or recovery. Data ports (A, C) and the management port (D) all depend on a correctly configured IP stack, so they would be inaccessible in this scenario.
