A company has a custom table 'u_training_course' with a reference field to 'sys_user' named 'u_instructor'. The requirement is that only users with the 'instructor' role can be selected in this field. Which approach should be used to enforce this?

Trap 1: Create a business rule on the table to check the role and reject…

Business rules run after submission, so invalid data can be saved momentarily.

Trap 2: Use a client script to validate the selection before form submission

Client scripts can be bypassed by direct API calls.

Trap 3: Configure an ACL on the reference field to restrict write access

ACLs control permissions, not the list of selectable values.

A
Create a business rule on the table to check the role and reject invalid selections
Why wrong: Business rules run after submission, so invalid data can be saved momentarily.
B
Add a reference qualifier on the field to filter users with the 'instructor' role
Reference qualifiers restrict the list dynamically.
C
Use a client script to validate the selection before form submission
Why wrong: Client scripts can be bypassed by direct API calls.
D
Configure an ACL on the reference field to restrict write access
Why wrong: ACLs control permissions, not the list of selectable values.

Question 2mediummultiple choice

A company has a custom table 'u_asset' with a reference field 'u_location' pointing to 'cmn_location'. When a user changes the location on an asset record, the system must automatically update the location on all related 'u_asset_software' records. Which approach should the developer use?

Trap 1: Create a Client Script that runs on load to update related records.

Client Scripts run on the client and cannot perform server-side updates.

Trap 2: Create an ACL to automatically propagate changes.

ACLs control access, not data propagation.

Trap 3: Create a UI Policy that sets the location field on related records.

UI Policies only control field attributes on the form.

A
Create a Client Script that runs on load to update related records.
Why wrong: Client Scripts run on the client and cannot perform server-side updates.
B
Create an ACL to automatically propagate changes.
Why wrong: ACLs control access, not data propagation.
C
Create a Business Rule that runs on update of the 'u_asset' table and updates related records.
Business Rules run server-side and can update related records.
D
Create a UI Policy that sets the location field on related records.
Why wrong: UI Policies only control field attributes on the form.

Question 3hardmultiple choice

A developer needs to create a new application scope. Which of the following is a best practice when defining the scope?

Trap 1: Use the global scope to avoid access restrictions.

Global scope is not recommended for custom applications; it can cause conflicts.

Scope names must be unique.

Trap 3: Create the scope and later change the name if needed.

Scope name cannot be changed after creation.

A
Set the scope to 'Protected' to prevent other applications from modifying its records.
Protected scope prevents unauthorized modifications.
B
Use the global scope to avoid access restrictions.
Why wrong: Global scope is not recommended for custom applications; it can cause conflicts.
C
Use a scope name that is already in use to leverage existing configurations.
Why wrong: Scope names must be unique.
D

Why wrong: Scope name cannot be changed after creation.

Question 4hardmultiple choice

An application has a custom table 'u_project' with a field 'u_status' (choice list: Not Started, In Progress, Completed). The developer wants to prevent any update to the record if the status is 'Completed'. Which approach should be used?

Trap 1: Create a Database View that filters out Completed records.

Database Views are for reporting, not for preventing updates.

Trap 2: Create a Client Script that sets the field to read-only when status…

Client Scripts can only set read-only on the form, but updates via other channels are not blocked.

Trap 3: Create a UI Policy to disable the entire form when status is…

UI Policies only control form behavior, not server-side updates.

A
Create a Database View that filters out Completed records.
Why wrong: Database Views are for reporting, not for preventing updates.
B
Create a Client Script that sets the field to read-only when status is Completed.
Why wrong: Client Scripts can only set read-only on the form, but updates via other channels are not blocked.
C
Create a Business Rule with condition 'current.u_status.changesTo("Completed")' and set 'current.setAbortAction(true)' in the script.
Business Rules can abort actions before they occur.
D
Create a UI Policy to disable the entire form when status is Completed.
Why wrong: UI Policies only control form behavior, not server-side updates.

Question 5mediummultiple choice

A company has a custom table 'u_incident_task' that extends 'task'. The developer wants to add a field 'u_approval' that is a reference to 'sysapproval_approver'. Which method is the correct way to create this field?

'List' is not a valid field type in ServiceNow.

Trap 2: Create a 'Reference' field and set the table to 'task' and the…

The reference field should point to the table, not a field.

Trap 3: Create a 'Choice' field and populate it with sysapproval_approver…

This creates a proper reference to the sysapproval_approver table.
C
Create a 'Reference' field and set the table to 'task' and the reference field to 'sysapproval_approver'.
Why wrong: The reference field should point to the table, not a field.
D
