Which setting determines how long an administrative session remains active before timing out?

The setting that determines how long an administrative session remains active before timing out is the default timeout setting. This parameter specifies the duration for which an admin can remain logged in to the management interface without any activity before the session is automatically logged out for security reasons.

A default timeout setting is crucial for maintaining security on the firewall; it helps prevent unauthorized access in case an administrator leaves the session open inadvertently. The timeout duration can often be configured based on the organization's security policies and best practices, ensuring that administrative access is limited to necessary intervals, thereby minimizing potential exposure to risks.

While other options may relate to security and access, they do not pertain directly to the session timeout setting. For example, minimum password complexity focuses on the strength of passwords used to access the firewall, inactive session logout may refers to a feature that complements the timeout setting but does not explicitly define the duration, and administrative privileges pertain to the permissions granted to a user rather than the session duration itself.
