- A
Scoped applications can create records in global tables via GlideRecord without restrictions.
Why wrong: Creating records requires update rights.
- B
Scoped applications can call global script includes by default.
Why wrong: Access to global script includes requires explicit granting.
- C
To write to a global table, the application must be granted the 'global' scope or have appropriate ACLs.
Writing requires explicit permission.
- D
Scoped applications can update global tables without any additional configuration.
Why wrong: Update requires the application to be granted the 'global' application scope or specific rights.
- E
Scoped applications can read global tables using the 'global.' prefix.
Reading global tables is allowed by default.

SNOW-CAD Practice Question: Application development using ServiceNow Studio
This SNOW-CAD practice question tests your understanding of application development using servicenow studio. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 developer is creating a scoped application and needs to reference a global table (e.g., 'sys_user') from a business rule. Which TWO statements are true regarding cross-scope access?
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
✓
To write to a global table, the application must be granted the 'global' scope or have appropriate ACLs.
Option C is correct because scoped applications operate within an access control framework that restricts direct writes to global tables. To write to a global table like 'sys_user', the application must either be granted the 'global' scope (which removes scoping restrictions) or have appropriate ACLs that explicitly allow the write operation. Without these, a scoped application's GlideRecord write will fail due to cross-scope access controls enforced by the ServiceNow platform.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ServiceNow often tests the misconception that scoped applications can freely read and write global tables with just the 'global.' prefix, but the trap is that the prefix only grants read access—writes always require additional ACLs or global scope assignment.
Detailed technical explanation
How to think about this question
Under the hood, ServiceNow enforces cross-scope access via a combination of scope-level ACLs and the 'glide.scope.check' system property. When a scoped application attempts to read a global table, it uses the 'global.' prefix (e.g., 'new GlideRecord("global.sys_user")') to bypass the default scope isolation for reads only; writes still require explicit permissions. In real-world scenarios, a developer might create a scoped application that needs to log user activity to a global table, requiring them to either request ACL modifications or move the application to the global scope.
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 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.
