Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Dictionary Client Script
Why it's wrong here
Dictionary client scripts apply to standard dictionary entries on tables, not catalog item variables.
- ✗
UI Action with client-side script
Why it's wrong here
Service Catalog uses specific catalog client scripts rather than standard form UI actions for item submission validation.
- ✓
Catalog Client Script (onSubmit) returning false upon failure
Why this is correct
An onSubmit Catalog Client script can execute complex logic and halt form submission by returning false.
- ✗
Business Rule (Before Insert)
Why it's wrong here
Business rules execute server-side; client-side validation should happen on the client before submission.
