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.

Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. By setting the Accessible from field value to This application scope only, you can restrict the access to your data tables to only your application scope. This means that other application scopes cannot create, read, write, or delete records on your data tables, unless they have explicit permissions through Access Controls or other means.

The Form Designer is a tool that allows you to create and customize forms on the ServiceNow platform. The Form Designer has four main components:

Form layout: The form layout shows the preview of the form and allows you to drag and drop fields, sections, and related lists onto the form. You can also resize, reorder, and delete the elements on the form layout.

Page header: The page header shows the name of the table and the form that you are editing. You can also access the form properties, save the form, and switch to the form view from the page header.

Field navigator: The field navigator shows the list of available fields for the table and allows you to search, filter, and add fields to the form. You can also create new fields and edit existing fields from the field navigator.

Schema map: The schema map is not part of the Form Designer. The schema map is a separate tool that shows the relationships between tables and fields on the platform. You can access the schema map from the System Definition > Tables module or from the context menu of a table.

Creating applications in ServiceNow can help businesses replace outdated, inadequate, custom business applications and processes, extend service delivery and management to all enterprise departments, and extend the value of ServiceNow by leveraging its platform capabilities and integrations1234.

References = 1: What are Application Services? - ServiceNow 2: What is Application Development? - ServiceNow 3: Custom Applications in ServiceNow - The Cloud People 4: Build Custom Apps in ServiceNow – eBook – ServiceNow

 The correct combination of statements is a, b, and d. These are possible reasons to build custom applications on ServiceNow:

To replace outdated, inadequate, custom business applications and processes. Building custom applications on ServiceNow can help digitize and automate manual or legacy processes that are not covered by existing ServiceNow solutions. This can improve efficiency, data quality, user experience, and innovation.

To extend service delivery and management to all enterprise departments. Building custom applications on ServiceNow can help provide consistent and scalable services across different functions and teams in the organization. This can enhance collaboration, visibility, productivity, and customer satisfaction.

To extend the value of ServiceNow. Building custom applications on ServiceNow can help leverage the capabilities and benefits of the Now Platform®, such as low-code development tools, workflow automation engine, AI-powered insights, security operations, etc. This can increase agility, resilience, performance, and value.

The statement c is not a valid reason to build custom applications on ServiceNow:

To allow users full access to all ServiceNow tables, records, and fields. Building custom applications on ServiceNow does not imply granting users full access to all data and objects in ServiceNow. Access control rules still apply to custom applications and their components to ensure security and compliance. Reference: Build Custom Apps in ServiceNow – eBook

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.

Inbound Action scripts are server-side scripts that run when an email is received by the system. They can use the current object to access the record that is created or updated by the email, and the email object to access the properties and methods of the email message. The previous and event objects are not available in Inbound Action scripts. The producer object is only available in Record Producer scripts, which are used to create records from a service catalog item.

Catalog Client Scripts and Catalog UI Policies are the client-side scripts that apply to Record Producers. Catalog Client Scripts allow you to add or modify functionality on a catalog item or record producer form. Catalog UI Policies dynamically change information on a catalog item or record producer form. UI Scripts, UI Actions, Client Scripts, and UI Policies do not apply to Record Producers. Reference: Catalog client scripts, Catalog UI policies

Access Control scripts are server-side scripts that run when an Access Control rule is evaluated. They can use the gs and current objects to access the GlideSystem and GlideRecord methods, respectively. Some of the useful methods in Access Control scripts are:

gs.hasRole() - This method checks if the current user has a specified role. It returns true if the user has the role, and false otherwise. For example, gs.hasRole(‘admin’) will return true if the user is an administrator, and false otherwise.

current.isNewRecord() - This method checks if the current record is a new record that has not been inserted into the database yet. It returns true if the record is new, and false otherwise. For example, current.isNewRecord() will return true if the record is being created, and false if the record is being updated or deleted.

The methods g_user.hasRole() and current.isNew() are not part of the server-side scripting API. They are part of the client-side scripting API, which is used in Client Scripts and UI Policies. They cannot be used in Access Control scripts.

The Form Designer is a graphical interface for creating and customizing forms. The following statements are true for the Form Designer:

To add a field to the form layout, drag the field from the Fields tab to the desired destination on the form. This will add the field to the form view without changing the table definition.

To create a new field on a form’s table, drag the appropriate data type from the Field Types tab to the form and then configure the new field. This will create a new column on the table and add the field to the form view.

To remove a field from the form layout, hover over the field to enable the Action buttons, and select the Delete (X) button. This will remove the field from the form view but not from the table definition.

The following statement is false for the Form Designer:

To add a section to the form layout, drag it from the Field Types tab to the desired destination on the form. This is incorrect because sections are not available in the Field Types tab. To add a section, click the Add Section button on the toolbar or right-click on the form and select Add Section. References: Introduction to App Engine Studio for Developers, ServiceNow Studio Overview, Form Designer

Application developers configure ServiceNow using industry standard JavaScript to extend and add functionality. JavaScript is a scripting language that enables developers to create dynamic and interactive web pages, as well as manipulate data and logic on the server-side. ServiceNow provides various APIs and frameworks for developers to use JavaScript to customize and enhance the functionality of their applications, such as client scripts, UI policies, business rules, script includes, UI actions, and more. References: [ServiceNow Docs - JavaScript in ServiceNow], [ServiceNow Docs - Scripting in ServiceNow]

"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

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 trigger types in Flow Designer are Application, Record, Schedule, and Topic. Outbound Email is not a trigger type, but an action type that can be used in a flow to send an email message1. References: Flow Designer Trigger Types

When designing and creating a form, you can create sections to organize fields on a form. Sections are containers that group related fields together and provide a label and a description for the group. You can use sections to improve the readability and usability of the form. You can also collapse or expand sections to show or hide the fields within them.

The other options are not valid ways to organize fields on a form. Related lists are not fields, but lists of records that are related to the current record on the form. Tabs are not part of the form, but part of the application menu that allows you to navigate between different modules. Buttons are not fields, but elements that perform actions on the form, such as saving, updating, or deleting the record.

Roles are used to control access to applications and modules in the application navigator. Each application menu or module has a role field that specifies which role is required to view it. Users who do not have the specified role or a role that contains it will not see the application menu or module. Roles can also be used to control access to other features and capabilities in ServiceNow, such as tables, fields, scripts, and workflows.

Options for Creating Tables in Guided Application Creator:

Create a table from scratch: This option allows you to define a completely new table with custom fields and configurations.

Create a table from a template: You can use predefined table templates to speed up table creation. Templates often include pre-configured fields and settings.

Extend a table: This allows you to create a new table by inheriting fields and functionality from an existing table, enabling reuse and consistency.

Why Other Options Are Incorrect:

Option A (Link to external tables): Linking to external tables is not an option provided in the Guided Application Creator; external data is typically accessed through integration methods.

Option D (Run import jobs): Import jobs are used for data migration, not for table creation in the Guided Application Creator.

Option E (Upload a spreadsheet): While uploading a spreadsheet can create tables, this is a feature of Import Sets, not the Guided Application Creator.

Option F (Use API calls): API calls are for integration and not an option for creating tables directly in the Guided Application Creator.

The GlideUser object (g_user) is part of the client-side scripting API that provides information about the current user and the user’s preferences. It can be used in Client Scripts and UI Policies to customize the user interface based on the user’s role, language, time zone, etc. The workflow.scratchpad object is only available in Workflow scripts, which are used to automate processes on the platform. The current and previous objects are only available in server-side scripts, such as Business Rules and Script Includes. The GlideSystem object (gs) is also a server-side object that provides methods for logging, debugging, date and time calculations, etc.

The Weight field in an Email Notification determines which notification is sent when multiple notifications are triggered for the same record and recipients. Only the notification with the highest weight is sent. A weight value of zero means the notification is always sent when the notification’s When to send criteria is met. A weight value of -1 means that no email should be sent3. References: Email Notification Weight

You must script and configure all required behaviors Provided link has this statement: Extending an existing ServiceNow table means the new table inherits the parent table's columns as well as its business logic.

The following statements apply when extending an existing table:

The parent table’s Access Controls are evaluated when determining access to the new table’s records and fields. This is true because Access Control (ACL) rules are inherited from the parent table to the child table, unless the child table has its own ACL rules that override the parent table’s rules. ACL rules are used to restrict the access to the data and functionality of the ServiceNow platform based on the user’s roles and conditions.

The new table inherits the functionality built into the parent table. This is true because the new table inherits the business logic and the relationships from the parent table, such as Business Rules, Script Includes, UI Actions, UI Policies, and Reference Fields. Business logic and relationships are used to define the behavior and the structure of the data on the ServiceNow platform.

The new table inherits all of the fields from the parent table. This is true because the new table inherits the columns and the attributes from the parent table, such as Field Name, Data Type, Default Value, and Mandatory. Columns and attributes are used to define the properties and the characteristics of the data on the ServiceNow platform.

The following statement does not apply when extending an existing table:

You must script and configure all required behaviors. This is false because you do not have to script and configure all required behaviors when extending an existing table, as some of the behaviors are already inherited from the parent table, as explained above. However, you can script and configure additional or customized behaviors for the new table, such as adding new fields, creating new Business Rules, or modifying existing UI Actions. References: Table Extension, Access Control Rules

 When configuring a REST Message, the Endpoint is:

The URI of the data to be accessed, queried, or modified. This is the correct answer because the Endpoint is the part of the REST Message that specifies the location and the resource of the REST provider. The Endpoint is composed of the base URL and the resource path, which can include query parameters or variables. For example, the Endpoint for a REST Message that retrieves the weather information for a city from a web service could be https://api.openweathermap.org/data/2.5/weather?q=London.

The following are not correct definitions of the Endpoint when configuring a REST Message:

The commands to the REST script to stop execution. This is not correct because the commands to the REST script to stop execution are not part of the REST Message, but of the Scripted REST API, which is a feature that allows users to create custom REST endpoints on the ServiceNow platform. The commands to the REST script to stop execution are methods of the RESTAPIResponse object, such as setStatusCode, setError, or complete.

Information about the format of the returned data. This is not correct because the information about the format of the returned data is not part of the Endpoint, but of the HTTP headers or the Accept field of the REST Message. The HTTP headers or the Accept field can be used to specify the content type of the response, such as JSON, XML, or HTML.

The response from the provider indicating there is no data to send back. This is not correct because the response from the provider indicating there is no data to send back is not part of the Endpoint, but of the HTTP status code or the response body of the REST Message. The HTTP status code or the response body can be used to indicate the result of the REST request, such as 200 OK, 404 Not Found, or 500 Internal Server Error. References: REST Messages, Scripted REST APIs

Definition of a Spoke:A "spoke" is a scoped application or component of an application that contains Flow Designer actions and integrations. Spokes provide reusable functionality and are typically used to extend the capabilities of Flow Designer.

Why It’s Called a Spoke:

Spokes are part of the ServiceNow Flow Designer framework.

They contain predefined actions that are reusable across multiple flows. For example, an "Email Spoke" might include actions for sending emails or managing email configurations.

Why Other Options Are Incorrect:

Option B (Flow): This refers to an individual flow, not the application containing reusable actions.

Option C (Bundle): There is no such term as "Bundle" specific to Flow Designer in ServiceNow.

Option D (Action): While flows contain actions, the scoped application that houses these actions is referred to as a spoke.

The Field Watcher is a debugging tool that allows you to monitor the values of fields on a form as they change due to scripts or other actions. It can be used to debug Business Rules, Client Scripts, and Access Controls, but not Script Includes. Script Includes are server-side scripts that define reusable functions and classes. They are not associated with any specific field or form, and therefore cannot be watched by the Field Watcher.

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

Self-invoking. Learn JavaScript!

This type of JavaScript function is known as self-invoking or immediately-invoked function expression (IIFE). It is a function that is defined and executed at the same time, without being assigned to a variable or being called by another function. It is often used to create a local scope for variables and avoid polluting the global namespace.
