SNOW-CAD Creating and customizing tables and data Practice Question
A developer is working with a custom table 'u_project_task' that has a reference field 'u_project' pointing to the 'project' table. The developer wants to create a new field 'u_category' that lists values from a choice list, but the list should be filtered based on the value of 'u_project.u_type'. Which field type should be used?
⚠ Common exam trap
ServiceNow often tests the misconception that a calculated value or script can provide a dynamic choice list, but calculated values are for auto-populating fields, not for presenting filtered selection options to the user.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Choice field with a dependent choice list
A choice field with a dependent choice list allows the list of values in 'u_category' to be dynamically filtered based on the value of another field, in this case 'u_project.u_type'. This is the standard ServiceNow approach for creating cascading or conditional choice lists without custom scripting.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Choice field with a dependent choice list
Why this is correct
Dependent choice lists allow filtering based on a parent field.
- ✗
Choice field with a static choice list
Why it's wrong here
Static choices cannot be dynamically filtered.
- ✗
Calculated value using a script
Why it's wrong here
Calculated values are read-only and not selectable.
