Quick Answer
The answer is field value change and form load. These are the only two valid triggers for a UI Policy in ServiceNow, meaning a UI Policy can execute its actions—such as setting a field as mandatory—either when a specific field’s value changes or when the form initially loads. This is a core architectural constraint: UI Policies are client-side, declarative rules that react to these two events, unlike ACLs or business rules which operate on different layers. On the ServiceNow Certified Application Developer CAD exam, this concept frequently appears in multiple-choice questions that list distractors like “user role changes” or “record is submitted,” testing whether you understand the narrow scope of UI Policy triggers. A common trap is confusing UI Policies with client scripts, which can react to many more events; remember that UI Policies are purely declarative and limited to these two triggers. Memory tip: think of the “U” in UI Policy as standing for “Under two triggers”—field change and form load.
This SNOW-CAD practice question tests your understanding of designing interfaces and user experiences. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 TWO conditions can be used as triggers for a UI Policy to set a field as mandatory? (Choose two.)
A record is submitted
Why wrong: There is no 'on submit' trigger for UI Policies.
A specific field value changes
On change conditions are common for UI Policies.
The form is loaded
On load conditions apply when the form is opened.
An ACL evaluates to false
Why wrong: ACLs do not trigger UI Policies.
The user has a specific role
Why wrong: Roles can be checked in conditions, but role alone is not a trigger.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
A specific field value changes
UI Policies can be triggered by changes to a specific field value or when the form is loaded. ACLs and user roles are not triggers for UI Policies.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
A record is submitted
Why it's wrong here
There is no 'on submit' trigger for UI Policies.
A specific field value changes
Why this is correct
On change conditions are common for UI Policies.
Related concept
Standard ACLs match source addresses.
The form is loaded
Why this is correct
On load conditions apply when the form is opened.
Related concept
Standard ACLs match source addresses.
An ACL evaluates to false
Why it's wrong here
ACLs do not trigger UI Policies.
The user has a specific role
Why it's wrong here
Roles can be checked in conditions, but role alone is not a trigger.
Common exam traps
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
What to study next
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SNOW-CAD ACL questions on filtering logic and placement.
