SNOW-CAD Practice Question: Application development using ServiceNow Studio
A developer is troubleshooting a business rule in a scoped application that is not triggering. The rule is set to run 'before' query, with condition 'current.state == 1'. The table has read ACLs that restrict access. What is the most likely reason the business rule is not executing?
⚠ Common exam trap
ServiceNow often tests the misconception that business rules always execute regardless of security, when in fact ACLs are evaluated first and can prevent the rule from firing entirely.
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
✓
The user does not have read access to the records, so the query does not execute the rule.
Business rules that run 'before query' execute when a query is made against the table. If the user lacks read access due to ACL restrictions, the query itself is not permitted, so the business rule never triggers. This is because the platform's security layer evaluates ACLs before executing business rules, preventing the rule from running when the user cannot read the records.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The condition 'current.state == 1' is incorrect syntax.
Why it's wrong here
The syntax is valid for a before query business rule.
- ✗
Another business rule with higher order is preventing execution.
Why it's wrong here
Order only affects sequence, not whether a rule runs.
- ✓
The user does not have read access to the records, so the query does not execute the rule.
Why this is correct
Before query rules run only if the user can access the records.
- ✗
The business rule is scoped and cannot access the table.
Why it's wrong here
Scoped business rules can access tables within the same scope.
