SNOW-CAD Quick Quiz — 10 Questions

Question 1

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?

Accepted Answer

Add a reference qualifier on the field to filter users with the 'instructor' role. Option B is correct because a reference qualifier is the declarative way to filter the records available in a reference field on ServiceNow. By adding a condition like 'roles=instructor' to the reference qualifier of the 'u_instructor' field, only users with the 'instructor' role will appear in the lookup, enforcing the requirement at the database query level without custom scripting.

Answer

Create a business rule on the table to check the role and reject invalid selections

Answer

Use a client script to validate the selection before form submission

Answer

Configure an ACL on the reference field to restrict write access

Question 2

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?

Accepted Answer

Create a Business Rule that runs on update of the 'u_asset' table and updates related records.. Option C is correct because a Business Rule that runs on the 'update' operation of the 'u_asset' table can directly query and update all related 'u_asset_software' records using GlideRecord. This server-side logic ensures the location change is propagated reliably, regardless of how the asset record is updated (UI, web service, import set, etc.), and it executes within the same database transaction for data consistency.

Answer

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

Answer

Create an ACL to automatically propagate changes.

Answer

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

Question 3

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

Accepted Answer

Set the scope to 'Protected' to prevent other applications from modifying its records.. Setting the scope to 'Protected' is a best practice because it prevents other applications from modifying the application's records while still allowing the application to access records from other scopes. This balances security and interoperability, ensuring that the application's data integrity is maintained without unnecessarily restricting cross-scope access.

Answer

Use the global scope to avoid access restrictions.

Answer

Use a scope name that is already in use to leverage existing configurations.

Answer

Create the scope and later change the name if needed.

Question 4

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?

Accepted Answer

Create a Business Rule with condition 'current.u_status.changesTo("Completed")' and set 'current.setAbortAction(true)' in the script.. Option C is correct because a Business Rule with the condition `current.u_status.changesTo('Completed')` triggers only when the status field transitions to 'Completed', and `current.setAbortAction(true)` aborts the database update operation at the server level, ensuring that no update can persist regardless of client-side behavior. This approach enforces the restriction server-side, which is essential for data integrity because client-side scripts can be bypassed.

Answer

Create a Database View that filters out Completed records.

Answer

Create a Client Script that sets the field to read-only when status is Completed.

Answer

Create a UI Policy to disable the entire form when status is Completed.

Question 5

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?

Accepted Answer

Create a 'Reference' field and set the reference table to 'sysapproval_approver'.. Option B is correct because a Reference field is designed to create a link from one table to another, storing the sys_id of the target record. Since 'u_approval' needs to point to a specific record in the 'sysapproval_approver' table, a Reference field with the reference table set to 'sysapproval_approver' is the appropriate method. This ensures referential integrity and allows the platform to resolve display values and enforce relationships.

Answer

Create a 'List' field type and set the table to sysapproval_approver.

Answer

Create a 'Reference' field and set the table to 'task' and the reference field to 'sysapproval_approver'.

Answer

Create a 'Choice' field and populate it with sysapproval_approver values.

Question 6

Which TWO of the following are types of UI Policies? (Choose two.)

Accepted Answer

On change. UI Policies in ServiceNow are client-side scripts that run on the browser to control the behavior of fields on a form. The 'On change' type triggers when a specified field's value changes, allowing dynamic field updates or visibility changes. The 'On load' type triggers when the form is initially loaded, enabling default value setting or field configuration before user interaction.

Answer

On submit

Answer

On delete

Answer

On query

Question 7

The ACL above is on the 'incident' table. A user with role 'itil' tries to update an incident record. What will happen?

Accepted Answer

The user will be denied because the condition fails.. The ACL (Access Control Rule) on the 'incident' table has a condition that must evaluate to true for the user to be granted access. In this case, the condition fails for a user with role 'itil' attempting to update the record, so the script does not set answer = true, resulting in a denial of the operation. Option D is correct because the condition failing means the ACL denies the write operation.

Answer

The user will be prompted for credentials.

Answer

The user will be allowed because the condition is ignored for write operations.

Answer

The user will be allowed because the script sets answer = true.

Question 8

A developer is asked to add a custom button to the Service Portal form for the 'incident' table. The button should trigger a client script that displays a confirmation dialog before submitting the form. Which approach should the developer use?

Accepted Answer

Create a UI Policy on the incident table with a client script that shows the button conditionally.. Option A is correct because UI Policies in Service Portal allow you to define client-side conditions and scripts that can dynamically show or hide UI elements like buttons. By creating a UI Policy on the incident table with a client script, you can conditionally display a custom button that triggers a confirmation dialog before form submission, leveraging the client-side execution context without server round-trips.

Answer

Create an Access Control Rule (ACL) on the incident table and attach a client script.

Answer

Create a Business Rule on the incident table that injects a button via server-side code.

Answer

Create a UI Action on the incident table with a client script and set the 'Show insert' condition.

Question 9

Which TWO of the following are valid ways to customize the Service Portal login page?

Accepted Answer

Override the 'Login' page in the portal record by creating a new page and setting it as the login page.. Option B is correct because the Service Portal login page can be customized by overriding the 'Login' page in the portal record. This is done by creating a new page (e.g., a copy of the default login page) and setting it as the login page in the portal's configuration, which allows full control over the layout and widgets used. Option D is correct because CSS variables defined in the portal's theme (SCSS) can be used to style login page elements, as the theme's SCSS is compiled and applied globally to all portal pages, including the login page.

Answer

Create a new widget instance on the 'loginpage' widget slot.

Answer

Add a widget option to the login widget to inject custom CSS.

Answer

Set the 'login.css' property in sys_properties to a custom stylesheet URL.

Question 10

When configuring a Service Portal page, a developer wants to ensure that a specific widget appears only to users with the 'itil' role. Which approach should be used?

Accepted Answer

Set the 'Roles' property on the widget instance within the page designer.. Option C is correct because the 'Roles' property on a widget instance within the Service Portal page designer directly controls which roles can view that specific widget. This is the intended declarative approach for role-based visibility at the widget instance level, without requiring custom scripting or ACLs.

Answer

Pass a role check from the server script to the client controller via widget options.

Answer

Write an Access Control Rule (ACL) on the widget's table to restrict access.

Answer

Create a UI Policy on the portal table that hides the widget based on user roles.
