How many system configurations can be saved locally on the SMA?

The correct choice regarding the number of system configurations that can be saved locally on the SonicWall Secure Mobile Access (SMA) appliance is indeed 20 configurations. This limitation is designed to allow administrators to manage and maintain a reasonable number of backup configurations without overwhelming the system or creating complexity when restoring configurations.

Saving 20 configurations provides a balance between having enough options to roll back to previous setups or implement different configurations as needed while ensuring that storage and management are efficient. This capability is particularly useful for testing changes in configuration, troubleshooting issues, or maintaining a historical record of system setups.

The option of 20 reflects a strategic design decision by SonicWall, ensuring that users can have flexibility while maintaining operational integrity. Other options suggest either too few or too many configurations, which would not align with the practical requirements of effective configuration management in a secure mobile access environment.
