• This class allows you to create and manipulate dialog windows on the user interface. You can use this class to display messages, forms, or custom HTML content in a modal window.
• GuideAjex: This class allows you to make asynchronous calls to the server and process the response. You can use this class to retrieve data, execute scripts, or perform actions on the server without reloading the page.
• GuideForm: This class allows you to access and manipulate the fields and values on a form. You can use this class to get or set field values, show or hide fields, add or remove options, or validate field inputs.

The class GuideRecord is not part of the Client side scoped APIs. GuideRecord is part of the Server side scoped APIs, which are a set of classes and methods that allow you to interact with the database and perform server-side logic on the ServiceNow platform. GuideRecord is a class that represents a record in a table and allows you to query, insert, update, or delete records on the server.

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

The objects that you can use in a Scheduled Script Execution (Scheduled Job) script are GlideSystem and GlideRecord. GlideSystem provides methods for performing system operations, such as logging, running background scripts, or getting system information. GlideRecord provides methods for working with records in the database, such as querying, updating, inserting, or deleting records. The current object is not available in Scheduled Script Execution scripts, as it refers to the current record on a form or list. The GlideUser object is also not available, as it refers to the current user session. Reference: Scheduled Script Execution, GlideSystem, GlideRecord

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]

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]

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 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.

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]

 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.

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.

References:

• Application Access
• [GlideRecord methods]

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.

The source control operation used to store local changes on an instance for later application is called a stash. A stash is a temporary storage area for uncommitted changes that are not ready to be pushed to a remote repository. Developers can use stashes to save their work in progress without committing it to the local repository or discarding it. Stashes can be applied later to restore the changes to the working directory, or dropped if they are no longer needed. References: [ServiceNow Docs - Stash local changes], [ServiceNow Docs - Source control]

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

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()]

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

The purpose of application scoping is NOT to provide a way of tracking the user who developed an application. Application scoping does not store or display information about the user who created or modified an application or its artifacts. The purpose of application scoping is to provide a relationship between application artifacts, provide a namespace to prevent cross-application name collisions, and provide controls for how scripts from another scope can alter tables in a scoped application. References: [Product Documentation | ServiceNow], [Advantages of Scoped Applications in ServiceNow]

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

Create table from template is not an option for creating a table through the Guided Application Creator. The other options are available for creating a table in the app. Upload spreadsheet allows you to import data from an Excel file and create a table based on the spreadsheet columns and rows. Extend a table allows you to create a child table that inherits fields and behaviors from a parent table. Create table from scratch allows you to define your own fields and data types for a new table. Reference: Create tables

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

Search branch and merge branches are available features in Studio. Search branch allows you to search for a specific branch name or ID in your Git repository. Merge branches allows you to merge changes from one branch to another, resolving any conflicts that may arise. Push to external source control and push to update set are not available features in Studio. Push to external source control is a feature of Source Control Integration, which is a separate application from Studio. Push to update set is a feature of Update Set Previewer, which is also a separate application from Studio. Reference: Studio, Source Control Integration, Update Set Previewer

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.

References:

• [Workflow overview]
• [Workflow context]

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.

• [Date/Time field type]

An Access Control list (ACL) defines what data users can access and how they can access it in ServiceNow tables1. The ACL evaluates the user roles and the conditions defined in the ACL rules to determine the user’s access level2. In this case, the ACL rules for the table are as follows:

• table.None read Access Control for users with the admin and itil roles: This means that users with the admin or itil roles cannot read any field in the table unless there is a more specific rule that grants them access3.
• table. * read Access Control for users with the admin role: This means that users with the admin role can read all fields in the table.
• table. field3 read Access Control for users with the itil role: This means that users with the itil role can read only the field3 in the table.

Therefore, a user with the itil role can read only the field3 in the table, and not the other fields.

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

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 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

To link a ServiceNow application to a Git repository, you need to provide the user name, URL, and password of the Git account that hosts the repository12. The URL is the address of the Git repository that you want to link to the application. The user name and password are the credentials that you use to access the Git account. Alternatively, you can use a personal access token instead of a password for increased security3.

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.
