ServiceNow Certified System Administration Practice

What action does a ServiceNow Client Script usually perform?

1. Updates records in the database

2. Validates data before submission

3. Generates reports

4. Triggers a Business Rule

The correct answer is: Validates data before submission

A ServiceNow Client Script is specifically designed to operate on the user's browser and interact with the user interface. One of its primary functions is to validate data before it is submitted to the server. For instance, if a user fills out a form, the Client Script can check whether the required fields are filled in correctly, confirm that the entered values meet certain criteria, or provide immediate feedback to the user if any errors occur. This real-time validation not only enhances user experience but also minimizes incorrect data storage in the database, thereby ensuring data integrity. While updates to records in the database, report generation, or triggering Business Rules are important functionalities within ServiceNow, these actions are typically handled by other components. For example, database updates and Business Rules are managed on the server side, while reports are generated through specific reporting functions outside the scope of Client Scripts. Client Scripts maintain a focus on user interactions on the client side, making data validation a top priority in ensuring effective form submission and data accuracy.
