Which of the following is NOT included in a complete backup?

A complete backup of a system typically includes all configurations and settings necessary to restore the system to its operational state. Pending or unsaved changes, however, are not part of a complete backup because these are temporary states or modifications that have not yet been committed to the system's configuration.

When performing a backup, only the configurations that have been saved and finalized are included. This means that any unsaved changes will be lost if a backup is restored since they were never part of the official configuration at the time of the backup. Therefore, while access policy settings, certificates and private keys, and node-specific settings are all essential and saved configurations, pending or unsaved changes are excluded from a complete backup. This highlights the importance of ensuring that all changes are saved before backing up the system.
