What is a use case for Sandboxes?

Sandboxes serve as isolated environments where users can experiment with and test various functionalities without affecting the live production system. They are particularly useful for testing scripts, event handlers, and API-based applications, as users can validate that their code works correctly and integrates well with the broader system. This environment allows for troubleshooting and adjustments to be made safely, ensuring that any potential issues are addressed before changes are deployed to the production environment.

Other options mention scenarios that are either more suited to production environments or do not effectively leverage the primary strength of sandboxes. For instance, creating production-ready databases and storing archived case data are functions that typically require a stable environment, while training new users is best conducted in a controlled, but not isolated, setting that mimics real-life use without the risks associated with live testing.
