Administrators can grant non-admin users the ability to develop global applications. Delegated Development is for the scoped applications only

One of the uses of the ServiceNow REST API Explorer is to create sample code for sending REST requests to ServiceNow. The REST API Explorer is a tool that allows you to discover and test the ServiceNow REST APIs. You can select an API endpoint, set the HTTP method, parameters, headers, and body, and then execute the request. The REST API Explorer will show you the response status, headers, and body, as well as generate sample code for various languages and frameworks, such as cURL, Java, JavaScript, Node.js, Python, Ruby, and more. References: [Use the REST API Explorer - Product Documentation: Tokyo - ServiceNow], [Introduction to Scripted REST APIs - ServiceNow Developers]

When a ServiceNow instance requests information from a web service, ServiceNow is the web service consumer. A web service consumer is an application that sends requests to a web service provider and receives responses from it. A web service provider is an application that exposes its functionality as web services. A web service publisher is a person or organization that publishes web services for others to use. A web service specialist is a person who has expertise in developing or using web services. Reference: Web services

The Bar Chart and Pie Chart report types can be created by right-clicking on a column header in a table’s list. These report types show how individual pieces of data relate to the whole using proportional bars or slices. You can also choose different aggregation methods such as count, sum, average, min, max, or percent. Reference: [Create reports from lists]

A possible reason to build a custom app is to fulfill a specific use case on internal processes. For example, you may want to digitize a manual process that is not covered by an existing ServiceNow solution, such as managing inventory, tracking expenses, or scheduling events. Building a custom app on the Now Platform can help you automate workflows, improve data quality, and provide better user experiences. The other options are not valid reasons to build a custom app. To avoid using a code repository like GitHub or GitLab is not a reason to build a custom app, as you can still use source control integration with your custom app development. To create a custom integration for a 3rd party system is not a reason to build a custom app, as you can use integration tools such as IntegrationHub or REST APIs to connect with external systems without creating an app. To replace ServiceNow base tables is not a reason to build a custom app, as it is not recommended to modify or delete base tables that are essential for ServiceNow functionality. Reference: Build Custom Apps in ServiceNow – eBook

An application admin is a role that grants full access to an application and its tables, scripts, and other components1. An application admin can create, modify, and delete any element of the application, as well as publish and install it2. An application typically has an application admin role that is automatically created and assigned to the application creator3.

The syntax used in a Record Producer script to access values from Record Producer form fields is producer.variable_name. A Record Producer is a type of catalog item that allows users to create records on any table from the service catalog. A Record Producer script is a server-side script that runs when a Record Producer is submitted, and can be used to set values or perform actions on the generated record. The producer object is a global object that represents the Record Producer form and its variables. The variable_name is the name of the variable defined in the Record Producer. References: [ServiceNow Docs - Record producers], [ServiceNow Docs - Record producer script]

"Guided Application Creator is enabled via the Guided Application Creator (com.glide.sn-guided-app-creator) plugin, which is active by default in the Now Platform." Located under "Activation Information" section at this URL:

https://docs.servicenow.com/en-US/bundle/tokyo-application-development/page/build/guided-app-creator/concept/guided-app-creator.html

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]

"Use an existing MID Server to connect to a Source Control repository. Linking or importing an application through a MID Server enables access to repositories behind a firewall." https://docs.servicenow.com/bundle/tokyo-application-development/page/build/applications/concept/c_SourceControlIntegration.html

To see what scripts, reports, and other application artifacts will be in a published application, the best option is to examine the Application Files Related List in the application to be published. This will show all the application files that belong to the application, grouped by file type and scope. You can also filter, sort, or search the list to find specific files.

The following options are not the best ways to see what application artifacts will be in a published application:

Enter the name of the Application in the Global search field. This will perform a global text search on the instance and return any records that match the application name, which may include irrelevant or incomplete results.

Open the list of Update Sets for the instance. This will show all the update sets that have been created or imported on the instance, but not necessarily the ones that belong to the application to be published. Update sets are used to move customizations between instances, not to publish applications to the ServiceNow Store or Share.

Open the artifact records individually to verify the value in the Application field. This will require opening each record that may be part of the application and checking the Application field, which is tedious and error-prone. References: Publish an Application, Application Files

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.

 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.

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

The baseline behavior of a table in a privately-scoped application is that all application scopes can read from the table. A privately-scoped application is an application that restricts write access to its tables and resources to scripts within the same scope. However, read access is allowed by default for all scopes, unless the administrator explicitly denies it using an Access Control rule. This allows for data sharing between different applications while maintaining data integrity and security. References: [Product Documentation | ServiceNow], [Advantages of Scoped Applications in ServiceNow]

Web services are software systems that use standardized protocols and formats, such as XML and HTTP, to exchange data and messages between different applications or systems over the Internet or other networks12. Web services enable interoperability and integration among diverse software components, regardless of their programming languages, platforms, or architectures34.

Comprehensive and Detailed Step-by-Step Explanation:

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.

References:

ServiceNow Developer Documentation on Flow Designer Spokes​.

Checkbox tooltip: "Show this module when the user has the specified roles. Otherwise the user must have the roles specified by both the application menu and the module."

The following is true for the Override application menu roles configuration option when configuring a module:

Users with the module role but without access to the application menu access the module. This is true because the Override application menu roles option allows users to bypass the application menu role requirement and access the module directly if they have the module role. For example, if a module has the itil role and the Override application menu roles option enabled, and the application menu has the admin role, then a user who has the itil role but not the admin role can still access the module.

The following are not true for the Override application menu roles configuration option when configuring a module:

Self-Service users can access the module even though they do not have roles. This is false because the Override application menu roles option does not grant access to the module to users who do not have any roles. Self-Service users are users who do not have any roles assigned to them and can only access the Self-Service portal and the Knowledge Base. To access the module, users need to have at least the module role.

Admin is given access to the module even if Access Controls would ordinarily prevent access. This is false because the Override application menu roles option does not override the Access Control (ACL) rules that apply to the module. Access Control rules are used to restrict the access to the data and functionality of the ServiceNow platform based on the user’s roles and conditions. Admin is a role

The Event Registry is a table that stores the definitions of all the Events that can be triggered or processed by the ServiceNow system1. The Event Registry allows ServiceNow to react when Events are generated by executing actions such as sending notifications, running scripts, or starting workflows2. The Event Registry also provides information about the Event parameters, description, and source3.

References = 1: Event Registry - ServiceNow Docs 2: Event Management - ServiceNow Docs 3: Event Registry form - ServiceNow Docs

An example of when an application might not use a Scheduled Script Execution (Scheduled Job) is when the application needs to run a client-side script at the same time every day. A Scheduled Script Execution is a server-side script that runs on a specified schedule and performs some action on the server or database. A client-side script runs on the user’s browser and cannot be scheduled by ServiceNow. The other options are examples of when an application might use a Scheduled Script Execution, such as sending email reminders, running a clean up script, or querying the database for unassigned records. Reference: Scheduled Script Execution, Client scripts

There is no "copy" button on the application record (at least I couldn't see one). Also, see here: https://docs.servicenow.com/bundle/sandiego-application-development/page/build/applications/reference/r_ManagingApplications.html

The application name is not required to link a ServiceNow application to a Git repository. You only need to provide the URL, user name, and password of the Git repository, as well as the branch name and the authentication type. The application name is automatically generated based on the scope name of your application. Reference: [Link an application to a Git repository]

https://developer.servicenow.com/dev.do#!/reference/api/paris/server_legacy/c_GlideSystemAPI#r_GS-nowNoTZ

Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. You can use Application Access to control the following database operations:

Create: This operation allows the user to create new records on the table. You can enable or disable this operation by selecting or clearing the Can create option.

Delete: This operation allows the user to delete existing records on the table. You can enable or disable this operation by selecting or clearing the Can delete option.

Read: This operation allows the user to view the records on the table. You can enable or disable this operation by selecting or clearing the Can read option.

Write: This operation allows the user to modify the records on the table. You can enable or disable this operation by selecting or clearing the Can write option.

The one database operation that cannot be controlled with Application Access is Query. Query is not an operation, but a method of the GlideRecord class that is used to retrieve records from the database on the server-side. Query is not part of the Application Access rules, but it is affected by the Access Controls and the user’s roles.

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.

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. References: [W3Schools - JavaScript Function Definitions], [MDN Web Docs - Immediately-invoked function expressions]

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. References: [Product Documentation | ServiceNow], [How To Create a Scoped App in ServiceNow - YouTube]

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.

The ServiceNow REST API is a web service that allows you to interact with the ServiceNow platform using HTTP requests and responses. The ServiceNow REST API supports the following methods:

POST: This method allows you to create a new record or execute an action on the ServiceNow platform. For example, you can use the POST method to create an incident or run a script.

GET: This method allows you to retrieve information from the ServiceNow platform. For example, you can use the GET method to get the details of a user or a table.

DELETE: This method allows you to delete a record or a resource from the ServiceNow platform. For example, you can use the DELETE method to delete an attachment or a workflow context.

PUT: This method allows you to update a record or a resource on the ServiceNow platform. For example, you can use the PUT method to update the state of a task or the value of a system property.

PATCH: This method allows you to update a record or a resource on the ServiceNow platform by sending only the changes. For example, you can use the PATCH method to update the short description of an incident or the order of a module.

The method COPY is not part of the ServiceNow REST API. There is no COPY method in the HTTP protocol. To copy a record or a resource on the ServiceNow platform, you need to use the POST method with the clone action.

A Record Producer is a type of service catalog item that allows users to create records on a specified table. A Record Producer has the following characteristics:

Graphics can be included on the user interface: You can add images, icons, or banners to the Record Producer to make it more appealing and informative for the user. You can also use HTML and CSS to customize the layout and style of the Record Producer.

You can script behaviors of fields in the user interface: You can use Client Scripts and UI Policies to control the behavior and appearance of the fields on the Record Producer. For example, you can use Client Scripts to validate the field inputs, perform calculations, or populate default values. You can also use UI Policies to show or hide fields, make fields mandatory or read-only, or set field values based on conditions.

Each field prompts the user with a question rather than a field label: You can use the Variable Question field to define the question that prompts the user for the field value. The question can be more descriptive and user-friendly than the field label. For example, you can use the question “What is the name of the project?” instead of the field label “Name”.

The other statements are not true for Record Producers. Record Producers do not always insert records into the Requested Item [sc_req_item] table. They can insert records into any table that is specified in the Record Producer properties. Record Producers also do not have to be scripted. They can use the default script that maps the variable values to the record fields, or they can use a custom script that defines the logic for creating the record.

See list of triggers on right hand side of this webpage: https://docs.servicenow.com/en-US/bundle/tokyo-application-development/page/administer/flow-designer/reference/flow-triggers.html

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

The Create Branch operation is available from both Studio and the Git Repository. This operation allows you to create a new branch from an existing branch in your Git repository. You can use branches to work on different features or versions of your application without affecting the main branch. Reference: [Create a branch]

 The application development plan is a document that outlines the scope, objectives, deliverables, and timeline of a software project1. It should include the following business requirements and processes:

Data input/output: This describes what data is needed for the application to function, how the data is collected, stored, processed, and displayed, and what outputs are generated by the application2.

Business problem: This defines the problem or opportunity that the application aims to address, the current situation, the desired outcome, and the benefits of the solution3.

Process steps: This details the steps involved in the application development lifecycle, such as planning, designing, testing, deploying, and maintaining the application4.

Users/stakeholders: This identifies the people who will use, benefit from, or influence the application, their roles, responsibilities, and expectations, and how they will be involved in the project5.

A UI Action is a button, link, or choice that can be clicked by a user to perform an action, such as submitting a form or running a script. The following are UI Action types:

List choice. This is a UI Action that appears as a choice list on a list of records. It can be used to perform an action on multiple records at once, such as deleting or updating them.

Form button. This is a UI Action that appears as a button on a form. It can be used to perform an action on the current record, such as saving or approving it.

List banner button. This is a UI Action that appears as a button on the banner of a list of records. It can be used to perform an action on the entire list, such as exporting or printing it.

The following is not a UI Action type:

Form choice. This is not a UI Action type, but a field type. A form choice is a field that displays a choice list on a form. It can be used to select a value from a predefined set of options, such as priority or state. References: UI Actions, Field Types

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

A Display Business Rule has access to the current, g_scratchpad, and GlideSystem objects, but not the previous object. The previous object is only available to Before Business Rules4. References: Business Rule API

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.
