The command for configuring additional synchronization in network redundancy is "redundancy main-cpu auto-sync." This command is crucial in environments where high availability and redundancy are essential, such as in Cisco's High Availability solution using redundancy protocols. By enabling auto-sync, the primary and backup devices can automatically synchronize their configurations, ensuring that the backup device has the same settings as the active device. This minimizes configuration discrepancies that could lead to network issues if a failover occurs.

The other options do not accurately represent valid Cisco commands for synchronization in redundancy:

- "auto-sync standard" is not a recognized command in Cisco IOS for managing redundancy.

- "backup active" relates to designating a primary system but does not address the synchronization of configurations.

- "sync-config" lacks context and is not a standard command for setting up synchronization within Cisco redundant systems.

Understanding the need for synchronization in redundant systems emphasizes the importance of having a consistent network configuration, which this command addresses directly.
