SNOW-CAD Practice Test 21 — 15 Questions

Question 1

A developer writes a script to display the department name of the caller on a custom form. The script uses: gs.getUser().getDepartment().getName(). However, the script throws a null pointer exception for some users. Which is the most likely cause and solution?

Accepted Answer

Some users do not have a department assigned, and the script does not check for null. Option D is correct because the NullPointerException suggests that getDepartment() returned null for users without a department. Option A is wrong because the script is syntactically correct. Option B is wrong because reference exists. Option C is wrong because department records exist.

Answer

The Department table is empty

Answer

The script uses incorrect dot-walking syntax; use getValue('department') instead

Answer

The user table does not have a department reference field

Question 2

Refer to the exhibit. A dashboard filter configuration contains the above JSON. When the dashboard runs, it shows an 'Invalid filter condition' error. What is the issue?

Accepted Answer

The JSON has a trailing comma after the 'operator' line.. The JSON has a trailing comma after the 'operator' value, which is invalid JSON syntax. This causes the parser to fail.

Answer

The condition string is missing a closing parenthesis.

Answer

The operator should be 'OR' instead of 'AND'.

Answer

The assignment group name is misspelled.

Question 3

What is the primary purpose of the 'Theme and Branding' module in Service Portal?

Accepted Answer

To define global visual styles like colors and fonts. The Theme and Branding module allows administrators to define global styles such as colors, fonts, and logos that apply across all portal pages.

Answer

To create custom widgets

Answer

To manage portal page layouts

Answer

To configure portal security settings

Question 4

Which TWO accessibility considerations are essential when designing for Service Portal? (Choose two.)

Accepted Answer

Proper heading structure. Proper heading structure and keyboard navigation are essential for accessibility. Color alone should not convey information, and auto-play videos can be a barrier. Complex data tables can be made accessible but require proper markup.

Answer

Use of color alone for important information

Answer

Complex data tables without headers

Answer

Auto-play videos

Question 5

A company wants to display a list of open incidents on a Service Portal page. Which component should be used?

Accepted Answer

Data Table Widget. The Data Table Widget is the standard component for displaying lists of records in Service Portal. Option B is wrong because List View Widget is used in the backend UI, not on portals. Option C is for analytics. Option D is for displaying maps.

Answer

Map widget

Answer

Performance Analytics widget

Answer

List View Widget

Question 6

When designing a custom portal page, the developer notices that the page layout breaks on mobile devices. What is the most efficient approach to ensure responsiveness?

Accepted Answer

Implement Bootstrap grid classes. Service Portal uses Bootstrap for responsive design. Implementing Bootstrap grid classes is the standard and efficient method. Option A is not responsive. Option C is more work and less efficient. Option D would work but does not leverage the built-in framework.

Answer

Add a media query for each device

Answer

Use fixed pixel widths

Answer

Use a single-column layout

Question 7

A developer wants to create a responsive portal page that displays data in a two-column layout on desktop and a single column on mobile. Which approach should be used?

Accepted Answer

Use the Bootstrap grid with col-lg-6 and col-md-12 classes. Bootstrap's grid system with col-lg-6 and col-md-12 classes provides a responsive two-column to single-column transition. Column widgets are not for responsive layout.

Answer

Use a single-column layout with media queries

Answer

Use the Column widget in UI Builder

Answer

Use fixed-width tables

Question 8

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

Question 9

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 10

Which TWO approaches are valid for applying custom theming to Service Portal? (Choose two.)

Accepted Answer

Applying a custom LESS file via Theme and Branding. Modifying Bootstrap CSS directly is not upgrade-safe. Overwriting widget CSS via instance options is not a global theming approach. The correct methods are using the Theme and Branding module and applying custom LESS files.

Answer

Overwriting widget CSS via widget instance options

Answer

Modifying the Bootstrap CSS directly

Answer

Using the CSS Variable Editor in UI Builder

Question 11

Which method is recommended for applying custom CSS to a Service Portal page?

Accepted Answer

Use the CSS Variable Editor in UI Builder. The CSS Variable Editor (or Theme and Branding) is the standard way to customize CSS in Service Portal. Customizing Bootstrap directly is not recommended.

Answer

Modify the Bootstrap CSS file directly

Answer

Add inline styles in the page template

Answer

Override CSS in each widget's instance options

Question 12

A widget's server script retrieves data from the 'incident' table using GlideRecord. A user with 'itil' role can see some incidents in the backend but the widget shows no data. What could be the reason?

Accepted Answer

The portal page has a visibility condition that excludes the user. Widget server scripts respect ACLs. If the widget is assigned to a portal that does not have the correct user criteria, or if the user's portal roles differ from backend roles, the data may not be visible.

Answer

The GlideRecord query does not include the user's assignment group filter

Answer

The widget is using client-side REST API instead of server-side

Answer

The widget's server script is not returning data because of a syntax error

Question 13

A developer writes a widget client controller that uses spUtil.get to fetch data from the server. The data is correctly returned, but the widget does not update the UI. What is the most likely cause?

Accepted Answer

The callback does not assign the result to a $scope variable. spUtil.get returns a promise, and the success callback should assign to $scope to trigger digest cycle. If the callback does not update a $scope property, the view will not update.

Answer

The widget's HTML template does not reference the correct variable name

Answer

The server script did not set data correctly

Answer

The spUtil.get method is deprecated

Question 14

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 component configuration defines a section with a field, but the template must reference the section and field IDs to render. If the template does not include the section or field, the component will not display the title. Option C is correct. Option A is incorrect because states do not affect field defaults. Option B is unlikely if registered correctly. Option D is incorrect because conditions are not required.

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 15

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.
