SNOW-CAD Practice Test 23 — 15 Questions

Question 1

A service portal developer needs to create a spreadsheet-like view for bulk editing incident records directly in the portal. Which ServiceNow feature is designed for this purpose?

Accepted Answer

Use the 'Data Table' widget with the 'Inline Edit' option enabled.. The Data Table widget with inline editing allows users to edit records in a grid format, which is the intended solution for bulk editing in the portal.

Answer

Use the 'Form' widget with a multi-record template.

Answer

Use the 'Report' widget with a drill-down option.

Answer

Use a custom UI macro to display an HTML table with editable cells.

Question 2

Refer to the exhibit. A developer creates this UI Builder component but the header does not display the custom title. What is the most likely cause?

Accepted Answer

The section id is missing from the template. The header fails to display the custom title because the template lacks the section ID that binds the field to the UI. In UI Builder, a component's template must include the section and field IDs to render dynamic content. Without the section ID, the field cannot be displayed, causing the title to be missing. Option D correctly identifies this. Options A, B, and C are incorrect: A is wrong because default values apply when no state is set, not the reverse; B is irrelevant as empty conditions do not cause this issue; C would prevent the entire component from rendering, not just the header.

Answer

The field default is not applied unless the state is set

Answer

The states array is empty of conditions

Answer

The component name is not correctly registered

Question 3

A developer is creating a service portal widget that shows a list of active incidents. The data should be refreshed every 30 seconds. What is the recommended design pattern?

Accepted Answer

Use a widget option to set the refresh rate and a server-side script to fetch data.. Using a server-side script with a polling model is the standard approach to periodically fetch data in a widget without overloading the client.

Answer

Use a server-side script with a polling model to return data on a timer.

Answer

Use a third-party library for WebSocket connections.

Answer

Use a client-side JavaScript interval to reload the page.

Question 4

A user reports that a field 'Cost Center' is not visible on a form, but the UI Policy condition to show it is met. What is the first step in troubleshooting?

Accepted Answer

Check the form layout to ensure the field is present on the form.. Checking the form layout ensures the field is actually placed on the form, as UI policies can only control visibility if the field exists on the form.

Answer

Check the client script that may be hiding the field.

Answer

Check the ACLs for the 'Cost Center' field.

Answer

Check the role requirements for the field.

Question 5

Which TWO conditions can be used as triggers for a UI Policy to set a field as mandatory? (Choose two.)

Accepted Answer

A specific field value changes. UI Policies can be triggered by changes to a specific field value or when the form is loaded. ACLs and user roles are not triggers for UI Policies.

Answer

A record is submitted

Answer

An ACL evaluates to false

Answer

The user has a specific role

Question 6

A developer is configuring a REST message to retrieve data from an external system. The external system returns XML responses. Which data format should the developer set the REST message to expect?

Accepted Answer

XML. The REST message must be configured to expect the same data format that the external system returns. Since the external system returns XML, the developer should set the expected format to XML.

Answer

JSON

Answer

Text

Answer

CSV

Question 7

A Service Portal widget uses an AngularJS controller that directly modifies the DOM using jQuery inside the controller. After a platform upgrade, the widget stops working properly. What is the most likely reason?

Accepted Answer

Direct DOM manipulation conflicts with AngularJS digest cycles. Service Portal's AngularJS-based architecture is moving away from direct DOM manipulation. The correct approach is to use AngularJS data binding. The upgrade may have changed the order of digest cycles, causing inconsistencies.

Answer

jQuery is no longer allowed

Answer

The widget's controller syntax changed

Answer

AngularJS was completely removed from the platform

Question 8

A script include has a function that uses the 'GlideRecordSecure' class. When called from a Business Rule in a different scope, it throws a security exception. What is the most likely cause?

Accepted Answer

The script include does not have the 'Accessible from' property set to all scopes.. The 'Accessible from' property on a Script Include controls which scopes can invoke its functions. When this property is not set to 'All scopes', a Business Rule in a different scope cannot call the Script Include, resulting in a security exception. The GlideRecordSecure class itself is accessible across scopes, but the Script Include's access restriction prevents the call.

Answer

The function is not defined as a static function.

Answer

The GlideRecordSecure class is not accessible from other scopes.

Answer

The script include is not marked as public.

Question 9

Which THREE are benefits of extending a table rather than creating a new table from scratch?

Accepted Answer

Supports creating multiple child tables from the same parent. Options B, C, and E are correct. Extending a table allows the child table to inherit all fields and relationships from the parent (C), enables adding new fields specific to the child without modifying the parent (E), and supports creating multiple child tables from the same parent (B). Option A is incorrect because although business rules and client scripts are inherited, they can be overridden and not all automatically apply without configuration. Option D is incorrect because child records do not automatically appear in parent table reports; reports must be configured to include child tables.

Answer

Automatically inherits all business rules and client scripts from the parent

Answer

Child records automatically appear in reports on the parent table

Question 10

A company wants to create a custom homepage for their service portal that displays three different data sources in a single view. The design must ensure that if one data source fails to load, the other two continue to function. Which implementation approach aligns best with this requirement?

Accepted Answer

Use three separate widgets each fetching their own data. Using three separate widgets isolates failures. Options A, C, and D can cause cascading failures. Option B ensures independence.

Answer

Use a parent widget that calls three child widgets

Answer

Use a widget that loads data in parallel with error handling

Answer

Use a single widget that fetches all data sequentially

Question 11

A company is integrating ServiceNow with an external ticketing system using a custom REST API. The integration should push updates from ServiceNow to the external system when a change request is approved. Which ServiceNow feature is best suited for this?

Accepted Answer

Business Rule with outbound REST call. A Business Rule with an outbound REST call is the best fit because it triggers automatically on the 'approved' state change of a change request and can execute a synchronous or asynchronous REST API call to the external ticketing system. This allows real-time push of updates without manual intervention or polling, directly meeting the requirement to push updates upon approval.

Answer

REST API Explorer

Answer

Access Control List (ACL)

Answer

Scheduled Job

Question 12

Which TWO of the following are valid ways to personalize a Service Portal widget without modifying the original widget code?

Accepted Answer

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.

Answer

Override the widget's server script via a Business Rule

Answer

Modify the widget's HTML template directly in the instance

Answer

Create a new widget from scratch

Question 13

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 14

A junior developer is creating a new catalog item for requesting software licenses. The catalog item includes several variables such as software name, quantity, and cost center. The business requires that when a user submits the request, the cost center variable should automatically populate with the cost center of the user's manager. The developer has written a script in the 'On Load' catalog client script to populate the cost center field. However, during testing, the cost center field remains empty after the form loads. The developer checks the script and finds it uses GlideAjax to call a Scripted REST API to fetch the manager's cost center. What is the most likely cause of the issue?

Accepted Answer

The 'On Load' client script runs before the GlideAjax response is received.. The 'On Load' catalog client script triggers when the form loads, but GlideAjax makes an asynchronous call to the server. The script continues executing without waiting for the response, so the cost center variable remains empty until the callback fires. Since the callback updates the field asynchronously, the field appears empty on load because the response hasn't arrived yet.

Answer

The cost center variable is read-only and cannot be set by client scripts.

Answer

The Scripted REST API is not accessible from client scripts due to cross-origin restrictions.

Answer

The GlideAjax call is missing the callback function.

Question 15

Which THREE best practices should be followed when designing a custom widget in Service Portal? (Choose three.)

Accepted Answer

Implement client-side validation. Implementing client-side validation improves user experience. Using spUtil for server calls ensures proper integration. Avoiding hard-coded strings supports internationalization. Global variables are discouraged, and synchronous AJAX calls block the UI.

Answer

Use synchronous AJAX calls

Answer

Use global variables to share data between widgets
