What options are used to preempt an administrator logged into the firewall?

The option to log out is the correct choice because it directly terminates the current administrative session on the firewall. When an administrator logs out, it ensures that no one else can maintain the same administrative session, effectively preempting the logged-in user.

This approach is essential in scenarios where administrative access needs to be secured, as it allows another administrator to take control of the firewall without waiting for the original user to log out voluntarily. Log out is a straightforward method that provides immediate access control and is commonly used in many systems to manage user sessions effectively.

Other options, while related to management or control of administrative access, do not provide the same immediate and complete preemption of an active session. For example, dropping into Non-Config mode would limit the configuration capabilities but wouldn’t necessarily preempt the logged-in administrator. Changing the administrator password could deny access in the future but does not affect the current session immediately. Disabling remote access would prevent new connections but wouldn’t impact those already logged in. Therefore, logging out is the most effective option for preempting an active administrator.
