SNOW-CAD Creating and customizing tables and data Practice Question
A small business uses ServiceNow to manage IT assets. They have a custom table 'u_company_asset' with fields for asset name, serial number, purchase date, and a reference field 'assigned_to' pointing to the User table. The administrator is asked to add a new field called 'Category' that will contain a short list of categories: Desktop, Laptop, Server, Network. The categories will not change frequently. The administrator also needs to ensure that when a user selects a category, a corresponding icon appears next to the field in the form. What is the most efficient way to accomplish this?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Choice field with the four categories, and then configure a UI policy to show different icons based on the selected value
A Choice field provides a drop-down list for predefined values that rarely change, and a UI policy can be configured to display different icons based on the selected category. Option A is wrong because a List Collector is used for multiple selections, not a single category. Option C is wrong because creating a custom table is unnecessary overhead for a fixed list. Option D is wrong because a single-line text field does not enforce predefined values.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a List Collector field to allow multiple categories
Why it's wrong here
List Collector is for multiple selections, but the requirement is for a single category selection.
- ✓
Create a Choice field with the four categories, and then configure a UI policy to show different icons based on the selected value
Why this is correct
Choice fields are ideal for static lists. Using a UI policy with client-side scripts can easily update an icon image based on the selected category.
- ✗
Create a custom table 'u_category' and a reference field on 'u_company_asset' pointing to it
Why it's wrong here
Creating a custom table for four static values is overly complex and introduces unnecessary maintenance.
- ✗
Use a single-line text field and manually enter the categories
Why it's wrong here
Free text fields allow inconsistent entry and cannot show icons dynamically without complex scripting.
