When an administrator sets apolicy(such asData Policies) that applies toall data entered into ServiceNow, it runs on theserver-side.

Why Data Policies Run on the Server?Data Policies apply to all data sources:

UI forms

Import Sets

Web Services (APIs, integrations)

Enforces field validation at the database level

Ensuresdata consistencyacrossall entry points.

Reducesclient-side dependencyfor validation.

Applies uniformly regardless of how the data is entered

UnlikeUI Policies(which only work on forms),Data Policiesensure field rules are enforcedeverywhere.

A. Network →Incorrect

Policies are not enforced at thenetwork level.

They operate within theServiceNow application.

C. Client →Incorrect

Client-side scripts (likeUI Policies or Client Scripts)onlyenforce validation within the browser.

Data Policies run at the server level, ensuring broader enforcement.

D. Browser →Incorrect

While UI Policies and Client Scripts run in the browser,Data Policies are applied on the server.
