The answer is a UI policy with a 'Choice' action set to 'Set choices' conditionally. This is the correct tool because UI policies operate on the client side, allowing them to dynamically filter the values in a choice field based on the selection made in another field on the same record, all without requiring a server round-trip. On the ServiceNow Certified Application Developer CAD exam, this question tests your understanding of client-side versus server-side logic, often presenting data policies or client scripts as traps. A common mistake is choosing a client script, which can technically achieve the same result but is not the standard declarative approach that UI policies provide. Remember the memory tip: "UI Policy Chooses Choices" — UI policies are the declarative way to conditionally set choice list options, keeping your configuration clean and maintainable.
SNOW-CAD Working with Data Practice Question
This SNOW-CAD practice question tests your understanding of working with data. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 wants to restrict the values in a choice field based on the value of another field on the same record. Which tool should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
UI policy with 'Choice' action set to 'Set choices' conditionally.
Option C is correct because a UI policy can conditionally set the values of a choice field on the client side. Option A (data policy) is server-side and cannot dynamically change choices. Option B (client script) can accomplish this but UI policy is the standard declarative approach. Option D (reference qualifier) is for reference fields, not choice fields.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Data policy with conditions.
Why it's wrong here
Data policies cannot change choice list options dynamically.
✓
UI policy with 'Choice' action set to 'Set choices' conditionally.
Why this is correct
UI policies can dynamically adjust choice lists based on field values.

✗
Reference qualifier on the choice field.
Why it's wrong here
Reference qualifiers apply only to reference fields, not choice fields.
✗
Client script that hides or shows options.
Why it's wrong here
While possible, UI policy is the intended tool.
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.
