Which type of script is executed when a record is displayed or updated in ServiceNow?

• A. User Interface Policy
• B. Client Script
• C. Business Rule
• D. Data Policy

Answer: (C)

The correct answer is that a Business Rule is executed when a record is displayed or updated in ServiceNow. Business Rules are server-side scripts that run when a record is inserted, updated, deleted, or queried, which makes them essential for managing business logic within the ServiceNow environment.

When a record is displayed (retrieved from the database) or updated (modified before being written back to the database), Business Rules are triggered according to the specified conditions. This ensures that any critical processes, such as data validation, updates to related records, or enforcing specific business logic, are enforced automatically in the background.

In contrast, User Interface Policies are meant for controlling form behavior and enforcing field visibility and read-only properties but do not execute logic on the server during record processing. Client Scripts are executed on the user's browser and are usually concerned with the client-side presentation and interactivity rather than manipulating data on the server. Data Policies are focused on ensuring data integrity and controlling the behavior of data when it's entered or modified, but they do not trigger any server-side processing like Business Rules do.

Therefore, Business Rules are distinctly suited for handling operations tied to the server and are the correct answer in this context.
