SNOW-CAD User Interface Development Practice Question
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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review the UI Policy conditions and the order of policies on the form
Option B is correct because checking the UI Policy conditions and order is the logical first step. Option A is incorrect because the field must already exist. Option C is incorrect because UI Policies do not use script includes. Option D is incorrect because ACLs do not affect mandatory behavior.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Verify that a script include used in the condition is accessible
Why it's wrong here
UI Policy conditions are typically simple conditions, not script includes.
✗
Ensure the field has a 'Mandatory' attribute on the dictionary
Why it's wrong here
UI Policy overrides dictionary settings; the field does not need to be mandatory by default.
✗
Check if the 'Mandatory' ACL on the field prevents modification
Why it's wrong here
ACLs control read/write access, not mandatory behavior.
✓
Review the UI Policy conditions and the order of policies on the form
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.
