Quick Answer
The correct answer includes the ability to hide a field, along with setting a field to read-only and making it mandatory, as these are the three primary actions that UI policies can perform on a ServiceNow form. UI policies are client-side scripts that dynamically control field behavior without requiring a server round-trip, allowing you to enforce business rules such as preventing edits on a field when a certain condition is met or requiring input only in specific scenarios. On the ServiceNow CSA exam, this concept tests your understanding of how UI policies differ from data policies and ACLs, with a common trap being that UI policies cannot change field values or run server-side logic—they only control visibility, editability, and requirement. To remember the three actions, think of the acronym "R-M-H": Read-only, Mandatory, and Hide, which covers every UI policy action available in the platform.
This SNOW-CSA practice question tests your understanding of ui, navigation and forms. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE actions can be performed using UI policies? (Choose three.)
Set a field's default value
Why wrong: Default values are set via field defaults or client scripts, not UI policies.
Make a field read-only
UI policies can set read-only.
Make a field mandatory
UI policies can set mandatory attributes.
Create a new field on the form
Why wrong: UI policies cannot create fields.
Hide a field
UI policies can set visibility.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Make a field read-only
Option B is correct because UI policies can set the 'read-only' attribute on a field, preventing users from modifying its value based on conditions. This is a core function of UI policies, which control field behavior on a form without requiring server-side scripting.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Set a field's default value
Why it's wrong here

Common exam traps
The trap here is that candidates often confuse UI policies with Data Policies or client scripts, assuming UI policies can set default values or create fields, but UI policies only modify existing field attributes on the client side.
Detailed technical explanation
UI policies execute client-side JavaScript in the browser, manipulating field attributes like 'readonly', 'mandatory', and 'visible' through the g_form API. They run on form load and on field value changes, but they cannot create or destroy fields because the form structure is defined server-side by the dictionary and form layout. A common real-world scenario is hiding a field like 'State' when a certain category is selected, using a UI policy to set the 'visible' attribute to false.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the SNOW-CSA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A ServiceNow administrator wants to create a new form section that appears only when the 'State' field is set to 'In Progress'. Which configuration should be used?
mediumWhy D: A UI Policy is the correct configuration because it allows an administrator to define conditions (e.g., 'State' is 'In Progress') that dynamically show or hide form sections, fields, or make fields mandatory/read-only on the client side without requiring a server round trip. This is the standard mechanism for controlling form section visibility based on field values in ServiceNow.
Variation 2. A system administrator needs to hide the 'Delete' button on the incident form for users with the 'itil' role, but allow it for administrators. What is the best approach?
hardWhy B: A UI Policy with a role condition is the best approach because it dynamically controls the visibility of the 'Delete' button on the incident form based on the user's role. UI Policies run client-side and can hide or show fields and buttons without requiring a page refresh, making them ideal for form-level UI changes. By setting the condition to 'role=itil' and the action to 'Hide', the button will be hidden for itil users but remain visible for administrators who do not have that condition applied.
Variation 3. An administrator needs to ensure that when a user changes the 'State' field to 'Resolved' on an incident form, the 'Resolution Notes' field becomes mandatory. What should be configured?
hardWhy C: A UI policy is the correct choice because it allows you to make a field mandatory based on a condition on the same form without requiring a server round-trip. When the 'State' field changes to 'Resolved', the UI policy can set the 'Resolution Notes' field to mandatory, and it runs client-side in real-time as the user interacts with the form.
