- A
Set condition to 'state=2' and add a script action that sets the field's visible attribute based on the checkbox value
Correct; the condition runs on server, and the script runs client-side to react to checkbox changes.
- B
Add both conditions in the condition builder: checkbox=true AND state=2
Why wrong: Incorrect; UI Policy conditions are evaluated on the server before the form loads, so dynamic client-side changes like checkbox state are not available in the condition.
- C
Set condition to 'state=2' and add a reverse if false action with a condition on the checkbox
Why wrong: Incorrect; reverse if false does not evaluate client-side conditions.
- D
Use a Client Script instead of UI Policy
Why wrong: Incorrect; client scripts can do the same, but the question asks for UI Policy approach.
Quick Answer
The correct approach is to set the UI Policy condition to 'state=2' and add a script action that hides the field based on the checkbox value. This is correct because UI Policies evaluate their condition first; if the condition is true, the defined actions run. A script action allows you to dynamically check additional criteria—like the checkbox state—within the same policy, rather than trying to cram multiple conditions into the UI Policy’s condition field. On the ServiceNow Certified Application Developer CAD exam, this tests your understanding of how UI Policy conditions and script actions work together to control field visibility, a common scenario for form customization. A frequent trap is attempting to write the checkbox logic directly into the condition field, which cannot evaluate scripted logic. Remember the memory tip: “Condition first, script for the rest”—use the condition for the primary filter and the script action for secondary, dynamic checks.
SNOW-CAD Core Application Development Practice Question
This SNOW-CAD practice question tests your understanding of core application development. 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.
A developer needs to create a UI Policy that hides a field when a checkbox is checked. The UI Policy has a condition: 'State is 2'. The field should be hidden when the checkbox is checked and state is 2. What is the correct approach?

Correct answer & explanation
Set condition to 'state=2' and add a script action that sets the field's visible attribute based on the checkbox value
UI Policies have both a condition and actions. The script action can evaluate additional conditions. The best practice is to set the condition to the primary filter (state=2) and add a script action to set the field's visibility based on the checkbox. Option B describes that correctly.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Incorrect; UI Policy conditions are evaluated on the server before the form loads, so dynamic client-side changes like checkbox state are not available in the condition.
- ✗
Set condition to 'state=2' and add a reverse if false action with a condition on the checkbox
Why it's wrong here
Incorrect; reverse if false does not evaluate client-side conditions.
- ✗
Use a Client Script instead of UI Policy
Why it's wrong here
Incorrect; client scripts can do the same, but the question asks for UI Policy approach.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the SNOW-CAD 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.
