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.
A scoped application includes a script include that is intended to be used by a business rule in the global scope. The script include is marked as 'Client callable: false' and 'Accessible from: This application only'. The business rule cannot call the script include. Which change fixes this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Change 'Accessible from' to 'All application scopes'
Option C is correct because the business rule in the global scope cannot access a script include restricted to 'This application only'. Changing 'Accessible from' to 'All application scopes' allows the global-scope business rule to invoke the script include, as cross-scope access is controlled by this property. The 'Client callable' setting is irrelevant for server-side business rules.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Set the script include name to start with 'global_'
Why it's wrong here
Incorrect; naming convention does not affect accessibility.
✗
Move the script include to the global scope
Why it's wrong here
Incorrect; moving it would work but is not the intended fix; you can keep it in the scoped app and make it accessible.
✓
Change 'Accessible from' to 'All application scopes'
Why this is correct
Correct; this setting allows the script include to be used by scripts in other scopes.

✗
Set 'Client callable' to true
Why it's wrong here
Incorrect; client callable is for GlideAjax calls from the client, not for server-side business rules.
Common exam traps
Common exam trap: answer the scenario, not the keyword
ServiceNow often tests the misconception that 'Client callable' controls all cross-scope access, but the trap here is that server-side cross-scope access is governed solely by the 'Accessible from' property, not the client-callable flag.
Detailed technical explanation
How to think about this question
In ServiceNow, the 'Accessible from' property on script includes enforces scope isolation at the application layer. When set to 'This application only', the script include's class is not visible to scripts in other scopes, even if the script include is marked as global. The 'Client callable' flag only affects whether the script include can be invoked via GlideAjax from client scripts; it has no bearing on server-side calls from business rules or other server-side scripts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the SNOW-CAD exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
