SNOW-CAD Core Application Development Practice Question
Exhibit
Refer to the exhibit.
ACL record:
Name: incident.write
Type: record
Operation: write
Condition: gs.hasRole('incident_manager')
Script:
answer = true;The ACL above is on the 'incident' table. A user with role 'itil' tries to update an incident record. What will happen?
⚠ Common exam trap
Many exam-takers assume that having a role like 'itil' automatically grants update access, but ACLs require both the role and the condition to be satisfied, and a failing condition overrides the role-based permission.
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 will be denied because the condition fails.
The ACL (Access Control Rule) on the 'incident' table has a condition that must evaluate to true for the user to be granted access. In this case, the condition fails for a user with role 'itil' attempting to update the record, so the script does not set answer = true, resulting in a denial of the operation. Option D is correct because the condition failing means the ACL denies the write operation.
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 user will be prompted for credentials.
Why it's wrong here
ACLs do not prompt for credentials.

The user will be allowed because the condition is ignored for write operations.
Why it's wrong here
Condition is always evaluated.

The user will be allowed because the script sets answer = true.
Why it's wrong here
The script only runs if the condition is true.
