SNOW-CAD Working with Data Practice Question
A company requires that when the 'state' field on an incident is set to 'Resolved', the 'resolution_code' field must be populated. Which mechanism should be used to enforce this rule?
Answer choices
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
✓
Data policy with condition state = 'Resolved' and mandatory resolution_code.
Data policies enforce field requirements on server-side updates and apply regardless of how the record is updated (UI, web services, etc.). In this scenario, a data policy with condition state='Resolved' and mandatory resolution_code ensures that the field must be populated when the state is set to Resolved. Option A (client script) is client-side only and can be bypassed. Option B (UI policy) is also client-side only. Option C (business rule) could be used to enforce the requirement, but data policy is the recommended mechanism for field-level validation because it is simpler and automatically handles all server-side operations. Therefore, option D is correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Client script that checks the state and pops up a message.
Why it's wrong here
Client scripts are client-side and can be bypassed.
- ✗
UI policy that sets the resolution_code field mandatory.
Why it's wrong here
UI policies are client-side and do not enforce server-side.
- ✗
Business rule with a condition on state change.
Why it's wrong here
A business rule with a condition on state change would not directly enforce the mandatory population of 'resolution_code' on the client-side form. While a 'before' business rule could abort the save if the field is empty, it does not dynamically make the field mandatory for the user to populate in real-time. This option is tempting as business rules are powerful for server-side automation and complex validations, such as automatically setting other field values or triggering events based on state changes.
- ✓
Data policy with condition state = 'Resolved' and mandatory resolution_code.
Why this is correct
Data policies provide server-side validation for field requirements.
