- A
Extend the widget via Widget Library
Extending a widget via the Widget Library creates a new version that inherits from the original, allowing customization.
- B
Override the widget's server script via a Business Rule
Why wrong: Business Rules cannot override widget server scripts; they apply to database operations.
- C
Modify the widget's HTML template directly in the instance
Why wrong: Direct modification alters the core widget and is not considered personalization; it affects all instances.
- D
Use a Widget Instance option to override properties
Widget Instance options allow you to customize behavior per instance without modifying the original widget.
- E
Create a new widget from scratch
Why wrong: Creating a new widget is not personalization; it is building a separate component.
SNOW-CAD Core Application Development Practice Question
This SNOW-CAD practice question tests your understanding of core application 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.
Which TWO of the following are valid ways to personalize a Service Portal widget without modifying the original widget code?
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
Extend the widget via Widget Library
Options A and D are correct because they allow personalization without altering the original widget code. Option A: Extending the widget via the Widget Library creates a copy that inherits from the original, enabling modifications without touching the source. Option D: Widget Instance options permit overriding properties like CSS, Angular providers, or client scripts at the instance level. Option B is incorrect because Business Rules cannot override a widget's server script; server scripts are tightly coupled to the widget and cannot be replaced by a Business Rule. Option C is incorrect because modifying the HTML template directly in the instance alters the original widget code. Option E is incorrect because creating a new widget from scratch is not a method of personalizing an existing widget; it is building a new one.
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.

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.
