SNOW-CAD Practice Test 24 — 15 Questions

Question 1

A developer is creating a custom Service Portal page for users to submit IT requests. The page must include a form that allows users to enter details and submit the request. The developer wants to use a standard Service Portal widget that provides a form interface for a record producer. Which widget should be used?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Record Producer. The Record Producer widget is purpose-built to render a record producer in Service Portal. It handles the display of variables and the submission process, creating a record in the specified table. This makes it the correct choice for a form that allows users to submit IT requests via a record producer.

Answer

Form

Answer

Simple Form

Answer

Catalog Item

Question 2

A developer is creating a custom UI Action on the Incident form that should only appear when the incident is in the 'Resolved' state. The button should be visible to users with the 'itil' role and should open a new window to a specific URL. Which combination of UI Action configuration fields should the developer set to meet these requirements?

Accepted Answer

Set the 'Condition' field to 'current.state == 6 && gs.hasRole("itil")' and the 'Onclick' field to 'window.open("https://example.com")'.. The Condition field of a UI Action determines whether the button is displayed, and it runs on the server. Using current.state == 6 checks for the Resolved state, and gs.hasRole('itil') checks for the required role. The Onclick field contains client-side JavaScript that runs when the button is clicked, allowing window.open to launch a new window. This combination ensures the button is only visible to the right users in the right state and performs the desired action.

Answer

Set the 'Condition' field to 'gs.hasRole("itil")' and the 'Onclick' field to 'if (current.state == 6) { window.open("https://example.com"); }'.

Answer

Set the 'Condition' field to 'current.state == 6' and the 'Onclick' field to 'window.open("https://example.com")', and add a UI Policy to hide the button for users without the itil role.

Answer

Set the 'Condition' field to 'current.state == 6' and the 'Script' field to 'if (gs.hasRole("itil")) { window.open("https://example.com"); }'.

Question 3

A developer needs to create a UI Action that is visible only to users with the 'itil' role and only when the incident state is 'Resolved'. The UI Action should appear as a button on the incident form. Which condition should be used in the UI Action's 'Condition' field?

Accepted Answer

gs.hasRole('itil') && current.state == 6. The UI Action condition must be a server-side JavaScript expression that evaluates to true or false. To check role membership, gs.hasRole('itil') is the correct method. To check the state value, current.state == 6 is correct because the incident state field stores integer values, with 6 representing Resolved. Using the logical AND ensures both conditions must be met for the button to appear.

Answer

gs.hasRole('itil') && current.state == 'Resolved'

Answer

current.state == 6 && gs.getUser().isMemberOf('itil')

Answer

gs.hasRole('itil') || current.state == 6

Question 4

A developer is building a custom Service Portal widget that includes a form for creating new incident records. The form should validate that the 'short_description' field is not empty before submission. Where should the validation logic be implemented?

Accepted Answer

In the widget's HTML template using AngularJS directives like 'ng-required' and 'ng-model'.. Client-side validation in Service Portal widgets is typically handled using AngularJS directives. Directives like 'ng-required' and 'ng-model' allow the form to enforce field requirements and prevent submission until valid. This provides immediate feedback without server round-trips. Server-side validation should still be implemented as a backup, but the primary pre-submission check belongs in the HTML template with AngularJS.

Answer

In the widget's server script using a GlideRecord insert and checking for empty values before insertion.

Answer

In the widget's client controller using the 'c.server.get' method to validate the field asynchronously.

Answer

In a UI Policy on the 'incident' table that makes the field mandatory when the form loads.

Question 5

A developer is creating a new Service Portal widget that displays a list of records from the incident table. The widget must allow users to filter the list by state and priority using dropdowns. The filtering should happen without a full page reload. Which TWO actions must the developer take to implement this functionality? (Choose two.)

Accepted Answer

Use the widget's server script to query the incident table and apply the filter conditions based on the client-side variables.. To implement dynamic filtering in a Service Portal widget, the developer must bind the dropdowns to client-side variables using AngularJS and then use the widget's server script to query the incident table with those filter conditions. The client controller triggers the server script when selections change, updating the list without a page reload.

Answer

Add a GlideAjax call in the client script to directly query the incident table and update the list.

Answer

Create a UI Policy on the incident table to filter records based on the dropdown values.

Answer

Configure the widget's option schema to include the state and priority fields as filter options.

Question 6

A developer needs to add a 'Resolve with Notes' button to the Incident form. When clicked, the button must open a modal dialog that contains a text area and a 'Submit' button. The modal must capture user input and then update the incident record via a GlideAjax call. Which UI mechanism should the developer use to implement this modal dialog?

Accepted Answer

Use the GlideModal class from the client-side API to open a dialog that contains a UI Page or a custom form.. The GlideModal class is the correct client-side API for creating modal dialogs in ServiceNow. It allows a developer to open a dialog containing custom HTML or a UI Page, capture user input, and then process it, for example by calling GlideAjax to update the record. The other options either use deprecated technology, non-existent methods, or misapply UI Policies.

Answer

Create a UI Action that uses the 'gs.submitModal' server-side method to render a modal dialog.

Answer

Create a UI Page with a dialog template and link it to a UI Action using the 'onclick' attribute.

Answer

Add a new section to the form and use a UI Policy to conditionally display it as a modal.

Question 7

A developer needs to create a business rule that runs before a record is inserted into the 'Problem' table. The rule should set the 'Opened by' field to the current user if it is empty. Which business rule configuration should the developer use?

Accepted Answer

When: before, Insert: true, Update: false, Delete: false, Query: false, and the script sets current.opened_by if empty.. A before insert business rule is the correct choice because it runs before the record is saved, allowing the script to modify the current object directly. Setting Insert to true and Update to false ensures the rule only applies to new records. The script can check if the opened_by field is empty and assign the current user's sys_id. This is efficient and meets the requirement without extra database operations.

Answer

When: before, Insert: false, Update: true, Delete: false, Query: false, and the script sets current.opened_by if empty.

Answer

When: before, Insert: true, Update: true, Delete: false, Query: false, and the script sets current.opened_by if empty.

Answer

When: after, Insert: true, Update: false, Delete: false, Query: false, and the script sets current.opened_by if empty.

Question 8

A developer is creating a Script Include that will be called from a client script. The Script Include must be accessible from the client side and should not expose sensitive logic. Which two statements are true regarding client-callable Script Includes? (Choose two.)

Accepted Answer

The Script Include can be called using the new operator in a client script.. Client-callable Script Includes require the 'Client callable' checkbox to be selected, which generates a client-side proxy. They are instantiated on the client using the new operator, and methods are called asynchronously. They execute on the server, allowing secure logic to run without exposing it to the client. They do not need to extend AbstractAjaxProcessor, and not all methods are automatically available; developers control which methods are exposed.

Answer

Client-callable Script Includes run entirely on the client side and do not make server calls.

Answer

All methods within the Script Include are automatically available to the client.

Answer

The Script Include must extend the AbstractAjaxProcessor class.

Question 9

A developer is creating a Service Portal widget that displays a list of tasks assigned to the current user. The widget's server script queries the task table and returns an array of task records. The client script uses ng-repeat to render the list. Users report that the list does not update when a new task is assigned to them unless they manually refresh the page. The developer wants the list to update automatically when a new task is assigned. Which approach should the developer take?

Accepted Answer

Add a record watcher in the client script using the spUtil.recordWatch method to listen for changes to the task table.. The spUtil.recordWatch method is designed for real-time updates in Service Portal. It uses the ServiceNow record watcher service to notify the client when records matching a filter change. By using recordWatch, the widget can automatically refresh its data when a new task is assigned, providing a seamless user experience. Polling, event queues, or non-existent properties do not achieve this efficiently.

Answer

Set the widget's 'Live Update' property to true in the widget editor.

Answer

Use a GlideAjax call in the client script to periodically poll the server for new tasks every 30 seconds.

Answer

Configure the widget's server script to use the gs.eventQueue method to push updates to the client.

Question 10

A developer is creating a custom Service Portal page for users to submit IT requests. The page must include a form that allows users to enter details and submit the request. The developer wants to use a standard Service Portal widget that provides a form interface for a record producer. Which widget should be used?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

A Server Script that queries the incident table and populates the data object.. A custom Service Portal widget fundamentally consists of a Server Script and a Client Controller, along with an HTML template. The Server Script retrieves and prepares the data on the server, and the Client Controller binds that data to the view and handles client-side behavior. Together they enable the widget to display the user's open incidents without relying on legacy Jelly or external REST APIs.

Answer

A UI Policy that enforces read-only access to the incident records.

Answer

A Jelly UI Macro that formats the incident records for display.

Answer

A Scripted REST API that exposes the incident table to the client.

Question 11

A developer is creating a UI Page that will be used in the classic UI to display a custom interface for managing change requests. The UI Page uses Jelly to query the change_request table and display a list. The developer wants to ensure that only users with the 'change_manager' role can access the UI Page and that the data displayed is filtered to show only change requests assigned to their assignment group. Which TWO steps must the developer take to enforce these requirements? (Choose two.)

Accepted Answer

Add a 'Roles' entry to the UI Page record specifying 'change_manager' to restrict access.. To restrict access to the UI Page, the developer should set the 'Roles' field on the UI Page record to 'change_manager'. This is enforced by the platform. To filter the data by the user's assignment group, the Jelly script must include a GlideRecord query that adds a condition based on the current user's assignment group. These two steps together meet the security and data filtering requirements.

Answer

Add a client script to the UI Page that checks the user's roles and hides the page if they are not a change manager.

Answer

Use the gs.hasRole method in the Jelly script to conditionally render the page content only for change managers.

Answer

Create a UI Policy on the change_request table that sets the 'assignment_group' field to read-only for non-managers.

Question 12

A developer wants to add a custom button to the incident form in the classic ServiceNow UI. When clicked, the button should open a URL that includes the current record's sys_id. Which mechanism should the developer use to add this button?

Accepted Answer

Create a UI Action with the 'Form button' checkbox selected and a client-side onClick function.. UI Actions are the correct mechanism for adding custom buttons to forms in the classic ServiceNow UI. By selecting the 'Form button' checkbox and providing a client-side onClick handler, the developer can construct a URL that includes the current record's sys_id and open it when the user clicks the button. This is the standard, supported approach for form button customization.

Answer

Create a Scripted REST API that returns the record's sys_id and call it from a form link.

Answer

Create a UI Policy that runs a script to open the URL when the form loads.

Answer

Create a Client Script of type onSubmit that opens the URL when the record is saved.

Question 13

A developer needs to create a new custom table to store employee training records. The table must have a field that references the User [sys_user] table, and the developer wants the field to display the user's full name on forms. Which field type should be used for this reference field?

Accepted Answer

Reference. The Reference field type is the correct choice because it creates a link to another table, stores the sys_id of the referenced record, and automatically displays the display value (e.g., user's full name). It enforces referential integrity and enables dot-walking. Other field types like String or Choice cannot establish this relationship or dynamically display the user's name.

Answer

String

Answer

Lookup Select Box

Answer

Choice

Question 14

A developer is designing a custom table 'u_vehicle' that will store vehicle records. The table must enforce that each vehicle has a unique license plate number. Which configuration should the developer apply to the license plate field to ensure uniqueness at the database level?

Accepted Answer

Set the field as mandatory and add a unique index.. To ensure each vehicle has a unique license plate, the field must be mandatory to prevent empty values, and a unique index must be applied to enforce uniqueness at the database level. This combination guarantees that no two records can have the same license plate number and that every record has a value. Other methods like business rules or UI policies do not provide the same level of database integrity.

Answer

Add a unique index only.

Answer

Create a before insert business rule that checks for duplicates.

Answer

Set the field as mandatory and create a UI policy that makes it read-only after creation.

Question 15

A developer is creating a custom UI Page that will be embedded in a Service Portal page via an iframe. The UI Page needs to access the current user's session and display personalized data. The developer wants to ensure the UI Page respects the Service Portal's theme and does not cause cross-origin issues. Which approach should the developer take?

Accepted Answer

Use the Service Portal widget framework to build the component instead of a separate UI Page.. Service Portal widgets are the intended method for creating reusable, theme-aware components that have access to the current user session and portal context. Using a widget eliminates cross-origin iframe issues and ensures consistent styling and behavior, making it the correct choice for embedding personalized content within a portal page.

Answer

Configure the UI Page to use the same domain as the Service Portal and rely on cookies for session sharing.

Answer

Use a UI Macro within a Service Portal widget to render the UI Page content directly.

Answer

Embed the UI Page in an iframe and use postMessage to communicate session data from the parent portal.
