- A
Verify that a script include used in the condition is accessible
Why wrong: UI Policy conditions are typically simple conditions, not script includes.
- B
Ensure the field has a 'Mandatory' attribute on the dictionary
Why wrong: UI Policy overrides dictionary settings; the field does not need to be mandatory by default.
- C
Check if the 'Mandatory' ACL on the field prevents modification
Why wrong: ACLs control read/write access, not mandatory behavior.
- D
Review the UI Policy conditions and the order of policies on the form
UI Policies are evaluated in order; a later policy may override the mandatory setting.
Question 349 of 500
First Step to Troubleshoot a Non-Triggering UI Policy
This SNOW-CAD practice question tests your understanding of user interface development. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A UI Policy is used to make a field mandatory when another field has a specific value. The policy is not triggering. What is the first step to troubleshoot?

Correct answer & explanation
✓
Review the UI Policy conditions and the order of policies on the form
Option D is correct because when a UI Policy is not triggering, the first step is to review the UI Policy conditions and the order of policies on the form. This ensures the condition is correctly set and not overridden by other policies. Option A is incorrect because script includes are not typically used in UI Policy conditions; UI Policies use simple conditions or scripts that can access script includes, but verifying accessibility is not the first step. Option B is incorrect because the 'Mandatory' attribute on the dictionary is a different configuration; UI Policy can make a field mandatory irrespective of dictionary attributes. Option C is incorrect because ACLs control access, not mandatory behavior; they do not prevent UI Policy from making a field mandatory.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Why this is correct
UI Policies are evaluated in order; a later policy may override the mandatory setting.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Standard ACLs match source addresses.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related SNOW-CAD ACL questions on filtering logic and placement.
