SNOW-CAD Core Application Development Practice Question
This SNOW-CAD practice question tests your understanding of core application development. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
An application has a custom table 'u_project' with a field 'u_status' (choice list: Not Started, In Progress, Completed). The developer wants to prevent any update to the record if the status is 'Completed'. Which approach 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
✓
Create a Business Rule with condition 'current.u_status.changesTo("Completed")' and set 'current.setAbortAction(true)' in the script.
Option C is correct because a Business Rule with the condition `current.u_status.changesTo('Completed')` triggers only when the status field transitions to 'Completed', and `current.setAbortAction(true)` aborts the database update operation at the server level, ensuring that no update can persist regardless of client-side behavior. This approach enforces the restriction server-side, which is essential for data integrity because client-side scripts can be bypassed.
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.
✗
Create a Database View that filters out Completed records.
Why it's wrong here
Database Views are for reporting, not for preventing updates.
✗
Create a Client Script that sets the field to read-only when status is Completed.
Why it's wrong here
Client Scripts can only set read-only on the form, but updates via other channels are not blocked.
✓
Create a Business Rule with condition 'current.u_status.changesTo("Completed")' and set 'current.setAbortAction(true)' in the script.
Why this is correct
Business Rules can abort actions before they occur.

Read the scenario before looking for a memorised answer.
✗
Create a UI Policy to disable the entire form when status is Completed.
Why it's wrong here
UI Policies only control form behavior, not server-side updates.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose client-side options (B or D) because they see 'prevent update' as a UI problem, but the exam tests the understanding that only server-side logic can enforce data integrity against all update sources.
Detailed technical explanation
How to think about this question
Under the hood, a Business Rule with `current.setAbortAction(true)` throws a `gs.addErrorMessage()` and rolls back the current database transaction, preventing the `sys_update` from being committed. This is crucial in scenarios where compliance requires that completed records remain immutable, such as in audit trails or financial close processes, because it blocks all update paths including inbound integrations and scheduled jobs.
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.
TExam Day Tips
→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.
