What is a locked restriction type for dashboards?

The correct answer indicates that when a dashboard has a locked restriction type, it prevents users from making any changes. This means users cannot add, remove, or modify any of the content displayed on the dashboard, ensuring that it remains in its original state. This feature is useful for maintaining a consistent view of critical data or metrics that should not be altered by end-users, providing a controlled environment for critical reporting and analysis.

This locked status can be particularly beneficial in scenarios where dashboards are set up for specific roles or compliance requirements, ensuring that users can't inadvertently alter important information or functional layouts that are essential for business operations. It effectively limits user interaction, thereby minimizing the risk of unintended changes that could affect data interpretation and decision-making processes.
