CAD Questions and Answers

Configuring the label of a field in a child table changes the label only on that table, not on the base table or the parent table. The base table is the table that contains the common fields for all the extended tables, and the parent table is the table that is directly extended by the child table. The label of a field on the base table or the parent table can be different from the label on the child table. References: [ServiceNow Docs - Table extension], [ServiceNow Community - How to change field label in child table]

The ServiceNow Store is not a downloadable content ServiceNow script archive, as that is available on the Script Library or the Script Repository. The ServiceNow Store is not an alternate name for the ServiceNow Developer Share site, as that is a separate site where developers can share applications, code snippets, UI pages, etc. Reference: ServiceNow Store

It is possible to change an application’s scope in ServiceNow, either from global to private or from private to global. However, changing the scope of an application may affect its functionality and compatibility with other applications. Therefore, it is recommended to test the application thoroughly before and after changing its scope.

The statement that is not true for Modules is that every Module must be associated with a table. A Module is the functionality within an Application Menu that opens a content page in the content frame or a separate tab or window. A Module can be associated with a table, a list, a form, a report, a script, or any other type of page. For example, the Open Module under the Incident Application Menu opens a list of incident records from the Incident table, while the Overview Module under the Performance Analytics Application Menu opens a dashboard page with various charts and widgets. The other statements are true for Modules. Access to Modules is controlled with roles, as each Module can have one or more roles specified in its definition that determine who can see and access it. Modules open content pages, as they are links to different types of pages that provide information and functionality to users. Every Module must be part of an Application Menu, as they are the second-level navigation options for Applications. Reference: Modules

A workflow is a tool that allows you to automate processes on the ServiceNow platform. A workflow consists of activities and transitions that define the logic and flow of the process. A workflow context is an instance of a workflow that is generated from a workflow version, executes activities, and follows transitions. A workflow context is associated with a specific record on a table and tracks the state and progress of the workflow. You can view and manage the workflow contexts from the Workflow Contexts module or the Workflow Contexts related list on a record.

The other options are not valid definitions of a workflow context. A checked out workflow is a workflow that is being edited by a user and has not been published yet. The table and conditions for a workflow are the criteria that determine when a workflow should run on a record. The business reason or process for a workflow is the purpose and function of the workflow.

g_form.showFieldMsg("field_name", "Hello World", "error"); Puts "Hello World" in an error message **below the specified field**. g_form.addInfoMessage() or g_form.addErrorMessage() place a blue box message at the top of the screen. Pg 126 of the CAD handbook

The method that prints a message on a blue background to the top of the current form by default is g_form.addInfoMessage(). The g_form object is a global object that provides access to form fields and UI elements on a form. The addInfoMessage() method is a method of the g_form object that displays an informational message next to the form header. The message has a blue background color by default, unless it is overridden by a CSS style. The addInfoMessage() method takes one argument, which is the message text to display. References: [ServiceNow Docs - GlideForm (g_form) API], [ServiceNow Docs - g_form.addInfoMessage()]

Access Controls are rules that define who can access what data and how they can access it. When configuring an Access Control, you can specify the table, operation, and role for the rule. You can also add a condition or a script to further refine the rule. If you do not add a condition or a script, the rule will apply to all records and fields on the table.

The statements A, B, and C are true for Access Controls that have no condition or script. For example:

• table.* will grant access to every field in a record. This means that the user can view and edit all the fields on the record, regardless of their role or any other criteria.
• table.None will grant access to every record on the table. This means that the user can view and edit all the records on the table, regardless of their role or any other criteria.
• table.field will grant access to a specific field in a record. This means that the user can view and edit only that field on the record, regardless of their role or any other criteria.

The statement D is not true for Access Controls that have no condition or script. table.id will not grant access to a specific record on the table. This is because the id is not a field name, but a unique identifier for the record. To grant access to a specific record on the table, you need to add a condition or a script that matches the id of the record.

Created UI policy on incident form, action set's cmdb_ci field as mandatory and script as not. result, field was not mandatory.

A UI Policy’s Actions execute before the UI Policy’s Scripts. Actions are predefined operations that can be applied to fields or sections, such as making them mandatory, read-only, visible, or setting a default value. Scripts are custom JavaScript code that can be used to perform more complex logic or validations. Actions are executed first, and then Scripts are executed if the UI Policy conditions are met. References: [ServiceNow Docs - UI policy actions], [ServiceNow Docs - UI policy scripts]

gs.print() and gs.log() are older and not available in scoped applications, whereas gs.debug(), gs.info(), gs.warn(), gs.error() work in both scoped applications and global are therefore are more versatile going forward in future versions.

"A table that extends another table is called a child class, and the table it extends is the parent class" - this is about halfway down in this link below: https://docs.servicenow.com/en-US/bundle/tokyo-platform-administration/page/administer/table-administration/concept/table-extension-and-classes.html

When creating a table, the Create module field allows you to automatically create a module for the table in the application menu. The default behavior of the new module is to display a list of all records from the table. This can be changed later by editing the module properties and specifying a different link type, such as form, URL, or script.

The welcome screen appears every time a new application is created through the Guided Application Creator. The welcome screen provides an overview of the steps involved in creating an application, such as defining the app name, scope, and tables, configuring the app user interface, and publishing the app. The other options are not true about the Guided Application Creator. The global scope option is turned off by default, as it is recommended to create applications in their own scope for better security and performance. A scope application user role is not automatically created, as the user can choose to create one or use an existing role for the app access control. Default access controls are not automatically created, as the user can define the read, write, create, and delete permissions for each table in the app. Reference: Guided App Creator

User-defined non-inherited fields can be deleted from a table in ServiceNow. These are fields that are created by users on a specific table and are not inherited from a parent table. Inherited fields cannot be deleted from a table, as they are defined on a parent table and shared by all child tables. Any field on a table cannot be deleted, as some fields are system-defined and essential for the table functionality. Table records are not deleted when a field is deleted, as the field deletion only affects the table structure and not the data. Reference: Delete fields

https://docs.servicenow.com/bundle/rome-application-development/page/build/applications/concept/c_ApplicationScope.html

The correct statement regarding Application Scope is that applications downloaded from 3rd party ServiceNow application developers cannot have naming conflicts. Application Scope is a feature that identifies and isolates applications and their related artifacts from other applications. Each scoped application has a unique namespace identifier that consists of a prefix and a scope name. This prevents cross-application name collisions and ensures that only authorized scripts can access or modify data in a scoped application.

https://docs.servicenow.com/bundle/paris-servicenow-platform/page/administer/flow-designer/concept/spokes.html

A spoke is a scoped application containing Flow Designer content dedicated to a particular application or record type. Flow Designer provides a set of core actions to automate Now Platform® processes. You can add application-specific core actions by activating the associated spoke.

Business Rule is server-side, so it uses GlideSystem API. gs.hasRoleExactly doesn't exist

In a Business Rule, the following returns true if the currently logged in user has the admin role:

• gs.hasRole(‘admin’). This is the correct answer because gs is the GlideSystem object, which provides methods for performing system operations, and hasRole is a method that checks if the current user has the specified role. For example, gs.hasRole(‘admin’) will return true if the current user has the admin role, and false otherwise.

The following do not return true if the currently logged in user has the admin role in a Business Rule:

• g_form.hasRoleExactly(‘admin’). This is not correct because g_form is the GlideForm object, which provides methods for manipulating forms, and hasRoleExactly is a method that checks if the current user has exactly the specified role and no other roles. For example, g_form.hasRoleExactly(‘admin’) will return true if the current user has only the admin role, and false if the current user has the admin role and any other role.
• g_form.hasRole(‘admin’). This is not correct because g_form is the GlideForm object, which provides methods for manipulating forms, and hasRole is a method that checks if the current user has the specified role or any role that contains the specified role. For example, g_form.hasRole(‘admin’) will return true if the current user has the admin role or any role that contains the admin role, such as admin_ui or admin_script.
• gs.hasRoleExactly(‘admin’). This is not correct because gs is the GlideSystem object, which provides methods for performing system operations, and hasRoleExactly is not a valid method of the gs object. There is no method that checks if the current user has exactly the specified role and no other roles in the gs object. References: Business Rules, GlideSystem, GlideForm

The method call that returns true only if the currently logged in user has the catalog_admin role and in no other case is g_user.hasRoleExactly(‘catalog_admin’). This method checks if the user has exactly one role, and returns true if it matches the argument. The other methods return true if the user has one or more roles, or if the user has any role from a list of arguments. References: [ServiceNow Docs - GlideUser API], [ServiceNow Community - Difference between hasRole() and hasRoleExactly()]

A Business Rule can take actions such as setting field values and generating an event without scripting. A Business Rule is a server-side script that runs when a record is displayed, inserted, updated, deleted, or queried. A Business Rule can use filter conditions, role conditions, and actions to define when and how it should run. Actions are predefined operations that can be performed on a record, such as setting field values, generating an event, adding a message, or writing to the system log. These actions do not require scripting and can be selected from a drop-down list. Reference: Use business rules and client scripts to control field values

A benefit of creating an Application Properties page for each application you develop is that Application Properties allow a developer or admin to make changes to an application’s behavior without modifying application artifacts. Application Properties are system properties that store configuration information for a specific application. They can be used to control various aspects of the application, such as feature flags, default values, thresholds, or URLs. By creating an Application Properties page, you can group and display all the properties related to your application in one place and make them easy to access and update. This way, you can avoid hard-coding static data in your application code and make your application more flexible and maintainable. Reference: Working with System Properties, Organizing your ServiceNow System Properties

The step that does not belong when creating a Utils Script Include is identifying the table. A Script Include is a server-side script that can contain one or more classes or functions that can be reused by other scripts. It does not depend on a specific table, but can access any table through GlideRecord or other APIs. The other steps are part of creating a Script Include class and its prototype object. References: [ServiceNow Docs - Script Includes], [ServiceNow Docs - GlideRecord API]

 Extending an existing table such as the Task table when creating a new application has several benefits, such as:

• You can repurpose existing fields by simply changing the label. For example, you can change the Short description field to Summary or Title for your new table.
• You can use existing fields with no modifications. For example, you can use the Assigned to, Priority, and State fields for your new table without changing anything.
• Existing logic from the parent table will be automatically applied to the new table. For example, you can inherit the Business Rules, Client Scripts, and UI Policies from the Task table for your new table.

The only option that is not true is d) All of the parent table records are copied to the new table. Extending a table does not copy any records from the parent table to the new table. It only creates a new table that inherits the fields and logic from the parent table.

References:

• [Extend a table]
• [Task table]

The elements of an Access Control are evaluated in the following order: Conditions, Roles, Script. The Conditions are a set of criteria that must be met for the Access Control to apply. The Roles are a list of user roles that are required to access the object. The Script is an optional script that can further restrict or allow access based on custom logic. If any of these elements return false, the Access Control denies access and stops evaluating the remaining elements. Reference: Access control rules

The data type of a field determines the format, validation, and display of the field value on a form. When selecting a data type for a field, you should consider the purpose and function of the field. The statements A, C, and D are correct for selecting a data type for a field. For example:

• Use the Choice data type to limit options in a field: The Choice data type allows you to create a field that has a predefined set of options for the user to select from. The options can be displayed as a drop-down list, radio buttons, or checkboxes. For example, you can use the Choice data type for a field that indicates the priority of a task.
• Use the Phone Number data type to automate phone number data validation: The Phone Number data type allows you to create a field that accepts and validates phone numbers. The field will automatically format the phone number according to the user’s locale and country code. For example, you can use the Phone Number data type for a field that stores the contact number of a user.
• Use the string data type for a free-form text field: The string data type allows you to create a field that accepts any text input from the user. The field can have a maximum length of 255 characters. For example, you can use the string data type for a field that captures the short description of an incident.

The statement B is not correct for selecting a data type for a field. There is no Data data type in ServiceNow. To enter the date and time of day, you should use the Date/Time data type. The Date/Time data type allows you to create a field that accepts and displays a date and time value. The field will use a calendar widget and a time picker to help the user enter the value. For example, you can use the Date/Time data type for a field that records the due date of a task.

Flow Designer variables can store record data and complex data using the following data types:

• Integer: A whole number that can be used in mathematical operations.
• Array: A collection of items that can be accessed by their index or iterated over using a For each action.
• String: Any kind of text, such as email addresses or the text contents of a file.

The Guided Application Creator (GAC) is a tool that helps you create applications on the ServiceNow platform by guiding you through the steps of defining the data model, user interface, and logic. When using the GAC, you can designate data tables in three ways:

• Upload an existing PDF: You can upload a PDF file that contains the table schema and sample data. The GAC will parse the PDF and create the table and fields based on the file content.
• Create a new table on the platform: You can create a new table on the platform by specifying the table name, label, and description. You can also add fields, indexes, and relationships to the table using the GAC.
• Upload an existing spreadsheet: You can upload a spreadsheet file that contains the table schema and sample data. The GAC will parse the spreadsheet and create the table and fields based on the file content.

The other options are not valid ways to designate data tables when using the GAC. You cannot upload an existing word processing document or use a freeform database. You can use an existing table on the platform, but you cannot designate it as a data table. You can only use it as a reference table for lookup fields.

 Tables that extend a table inherit the parent’s fields. Extending a table means creating a child table that shares the same columns and business logic as the parent table. For example, the Incident table extends the Task table, which means that all fields defined on the Task table are also available on the Incident table. Extending a table allows for reusing existing fields and behaviors without duplicating them on multiple tables. Reference: Table extension and classes
