CAD Certified Application Developer - ServiceNow Questions and Answers

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

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.

Table Extension in ServiceNow:Extending a table in ServiceNow means creating a child table based on a parent table. The child table inherits the fields, configurations, and functionality of the parent table.

What is Inherited:

Fields: All fields from the parent table are available in the child table.

Functionality: The child table benefits from any business logic or workflows defined for the parent table.

Access Controls: The child table respects the Access Control rules defined for the parent table unless explicitly overridden.

Why Other Options Are Incorrect:

Option B: This is incorrect because the new table does inherit fields from the parent table.

Option C: This is incorrect because you do not need to script or configure behaviors from scratch; they are inherited.

Option D: This is incorrect because Access Controls are not ignored; they still apply and can be extended or modified for the child table.

ServiceNow Developer Documentation on Table Inheritance​.

Application developers can specify which ServiceNow page a user sees after submitting a new record using the Record Producer UI by writing a script in the Record Producer’s Script field: producer.redirect = “”;. This script sets the redirect property of the producer object to the URL of the desired page. For example, producer.redirect = “home.do”; will redirect the user to the homepage after submitting the record. The other options are not valid ways to specify the redirect page for a Record Producer. Reference: Populate record producer data and redirect users

Global applications can use Automated Test Framework and Flow Designer features, but not Source Control and Delegated Development features. Source Control and Delegated Development features are only available to scoped applications . References: [Global vs Scoped Applications], [Delegated Development]

g_user is a global object available only in the client-side environment (Client Scripts, UI Policies, UI Actions).

From Development Handbook 4.0.4, p. 204:

“g_user is only available client-side. It returns session-specific info like roles and user ID. Not usable in Business Rules or Script Includes.”

While record producers are powerful tools for creating records via the Service Catalog, they cannot natively redirect users after submission. Redirection typically requires script hacks or custom widget configurations.

From ServiceNow Docs (Catalog Scripting):

“By default, record producers return the user to the catalog homepage. Redirection requires scripting using producer scripts or custom client logic.”

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]

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

 It is best practice to define the business requirements and the process(es) an application will manage as part of the application development plan. The following are some of the considerations to document as part of the business process:

Business problem. This is the description of the problem or opportunity that the application is intended to address or exploit. It should include the background, context, scope, and objectives of the problem or opportunity.

Data input/output. This is the specification of the data that the application will need to collect, store, manipulate, and display. It should include the data sources, formats, validations, transformations, and integrations of the data.

Users/stakeholders. This is the identification of the users and stakeholders who will be involved in or affected by the application. It should include the roles, responsibilities, expectations, and needs of the users and stakeholders.

Process steps. This is the definition of the steps and activities that the application will perform or support. It should include the inputs, outputs, triggers, conditions, and outcomes of each step or activity.

The following are not some of the considerations to document as part of the business process:

Project schedule. This is the estimation of the time and resources required to complete the application development project. It should include the milestones, deliverables, dependencies, and risks of the project. This is not part of the business process, but part of the project management plan.

Database capacity. This is the measurement of the amount of data that the application will generate and store in the database. It should include the data volume, growth rate, retention policy, and backup strategy of the data. This is not part of the business process, but part of the technical design and architecture of the application.

Available licenses. This is the number and type of licenses that the application will consume or require from the ServiceNow platform. It should include the license model, cost, and allocation of the licenses. This is not part of the business process, but part of the financial and legal aspects of the application. References: Application Development Process, Business Process Analysis

In ServiceNow, UI Actions are elements that facilitate user interaction within the platform, enabling users to perform specific actions such as form submissions, record updates, or triggering workflows. The valid types of UI Actions include:

Form Button: A button displayed on a form that, when clicked, executes a defined action.

Form Context Menu: An option added to the context menu of a form, providing additional actions related to the form's record.

Form Link: A hyperlink on a form that directs users to another page or executes a script.

List Banner Button: A button displayed in the banner area of a list, allowing actions to be performed on multiple records simultaneously.

List Choice: An option added to the list context menu for individual records, enabling actions on a selected record.

List Link: A hyperlink in a list that directs users to another page or executes a script.

Record Navigation Button: Buttons that facilitate navigation between records, such as Next and Previous buttons.

Options like "Workflow action" and "Form choice" are not recognized as standard UI Action types in ServiceNow.

For comprehensive details, refer to the official ServiceNow documentation on UI Actions.

The "Enforcing" mode ensures all cross-scope access is explicitly approved, logging and requiring manual approval if missing.

From ServiceNow Docs – Cross-Scope Access Controls:

“Enforcing mode logs cross-scope access attempts and blocks access unless explicit permission is granted.”

"Schema map: Provides a graphical representation of the relationships between tables."

https://docs.servicenow.com/bundle/tokyo-platform-administration/page/administer/table-administration/concept/c_TableAdministration.html

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]

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 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

In ServiceNow, Modules are navigation elements that provide access to various parts of the platform, such as forms, lists, reports, or other application components. They are organized within Application Menus to create a structured and intuitive navigation hierarchy.

Key characteristics of Modules:

Part of Application Menus: Every module is contained within an application menu. This organization helps users navigate to different areas of the platform efficiently. For instance, the "Incident" application menu may contain modules like "Create New" or "All Incidents."

Functionality: Modules can open various elements, including forms, lists, reports, or URLs. This flexibility allows modules to direct users to specific records, filtered lists, or external resources.

Association with Tables: While many modules are associated with specific tables (e.g., a module that displays a list of incidents is associated with the "Incident" table), it's not a strict requirement. Some modules may link to external URLs or perform actions not directly tied to a table.

Access Control: Access to modules is controlled through roles. Administrators can define which user roles have visibility and access to specific modules, ensuring that users only see modules relevant to their responsibilities.

For example, a module named "Active Incidents" under the "Incident" application menu might display a list of all active incident records. Access to this module can be restricted to users with the "itil" role, ensuring that only authorized personnel can view active incidents.

ServiceNow provides several methods to install applications onto an instance, each suited to different scenarios:

Import an Application from an XML File (Option A):

Description: Developers can export an application as an XML file and then import it into another ServiceNow instance.

Use Case: This method is commonly used for moving applications between instances, such as from development to production.

Procedure:

Navigate to "System Applications" > "Applications."

Click on the "Import" button.

Upload the XML file of the application.

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

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

The following is true for a Script Include with a Protection Policy value of Protected:

The Protection Policy is applied only if the application is downloaded from the ServiceNow App Store. This is true because the Protection Policy is a feature that allows developers to protect their Script Includes from being viewed or modified by other users when they distribute their applications through the ServiceNow App Store. The Protection Policy is only enforced when the application is installed from the App Store, not when it is developed or tested on the instance.

The following are not true for a Script Include with a Protection Policy value of Protected:

Any user with the protected_edit role can see and edit the Script Include. This is false because the protected_edit role is not related to the Protection Policy, but to the Access Control (ACL) rules. The protected_edit role allows users to edit protected fields on a table, such as the script field on the sys_script table, which stores the Business Rules. The Protection Policy does not use roles to control access to the Script Includes, but a cryptographic key that is generated when the application is published to the App Store.

The Protection policy option can only be enabled by a user with the admin role. This is false because the Protection policy option can be enabled by any user who has the application_admin role for the scoped application that contains the Script Include. The application_admin role grants full access to the application development and administration within the scope of the application.

The Protection Policy is applied only if the glide.app.apply_protection system property value is true. This is false because the glide.app.apply_protection system property is not related to the Protection Policy, but to the Application Restricted Caller Access (ARCA) feature. The ARCA feature allows developers to restrict the access to the Script Includes from other applications based on the caller’s scope. The glide.app.apply_protection system property determines whether the ARCA feature is enabled or disabled on the instance. References: Script Includes, Protect Script Includes, Application Restricted Caller Access

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.

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

In ServiceNow, Application Files are configuration records that define the various components and logic that constitute an application. These include artifacts such as:

Business Rules

Client Scripts

UI Actions

Script Includes

Tables and Fields

Workflows

These artifacts collectively define the functionality and behavior of the application. When an application is developed, ServiceNow automatically creates and manages these Application Files to represent the application's components.

Option C is correct because Application Files are the fundamental building blocks that comprise a ServiceNow application, representing its various components and configurations.

Options A, B, and D are incorrect:

A: XML exports of an Update Set represent changes made to an instance but are not synonymous with Application Files.

B: CSV files are typically used for data import/export and do not represent the configuration components of an application.

D: An XML export of table records pertains to data within a table, not the configuration artifacts that define application behavior.

Inherited fields in ServiceNow are fields that are part of a parent table and automatically become part of child tables through inheritance. This structure is foundational in the ServiceNow data model, ensuring that child tables maintain a consistent relationship with their parent tables.

Here’s why inherited fields cannot be deleted from a child table:

System Design:ServiceNow employs a table inheritance model where child tables derive fields and properties from parent tables. Deleting inherited fields from a child table would break the integrity of the data model, as those fields are shared across multiple tables.

Impact on Functionality:Many inherited fields, such as sys_created_on or sys_updated_by, are integral to the functionality of the platform. Removing them could disrupt workflows, reporting, and auditing capabilities.

Alternative Approach:If you want to hide or restrict access to inherited fields in a child table, you can use ACLs (Access Control Lists) to prevent users from viewing or modifying these fields. Another option is to use UI Policies or Client Scripts to control their visibility on forms.

Developer Note:Attempting to delete inherited fields violates ServiceNow’s core principles of maintaining a robust and unified data structure. The platform enforces these rules to ensure consistent behavior across all tables in the hierarchy.

ServiceNow Developer Documentation on Table Inheritance​.

Best practices outlined on SN Pro Tips regarding scoped application development and table structures​.

In ServiceNow, a Record Producer allows users to create records in a specific table through the Service Catalog. After a user submits a Record Producer, developers may want to redirect the user to a specific page. This can be achieved by setting the producer.redirect property within the Script field of the Record Producer.

For example:

javascript

CopyEdit

producer.redirect = 'incident.do?sys_id=' + current.sys_id;

This script redirects the user to the newly created incident record after submission.

Option A is incorrect because configuring the module that opens the Record Producer does not control the post-submission behavior.

Option C is unnecessary for simple redirection purposes; creating an application property to store the URL adds unnecessary complexity.

Option D is incorrect because using window.redirect in a Business Rule is not appropriate; Business Rules run on the server side and do not have access to the client-side

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

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]

Ensuring that users receive email notifications in ServiceNow requires verifying specific attributes on the user record:

A. The Email field must have a valid value: This is correct. The Email field should contain a valid email address, as notifications are sent to the address specified in this field.

B. The user must not be locked out: While it's important for user access, being locked out does not directly impact the sending of email notifications.

C. The First name and Last name fields must have values: These fields are for identification purposes and do not affect email notification delivery.

D. Active must be true: This is correct. Only active users are eligible to receive email notifications. If a user is marked as inactive, notifications will not be sent to them.

E. Delegation must be enabled: Delegation pertains to assigning responsibilities to another user and does not influence the receipt of email notifications.

For effective email notification delivery, always ensure that the user's Email field contains a valid address and that the Active field is set to true.

Application Access settings on a table control which operations external applications (in other scopes) can perform. The main controllable operations are:

Can create

Can read (query)

Can update

Can delete

From Development Handbook 4.0.4, p. 192:

“Application access settings determine whether another scope can read, write, create, or delete records from this table... Execute is not a valid database operation — it pertains to script includes or other executable logic.”

To include specific records from a table (often referred to as seed data) when distributing an application in ServiceNow, developers must add these records to the application as application files. This ensures that when the application is installed on another instance, the specified records are included.

Option C is correct because using the "Create Application Files" feature allows developers to select specific records to include in the application package. This process creates application files for the selected records, ensuring they are installed along with the application on other instances.

Options A, B, and D are incorrect:

A: The activation status of Table A and whether it extends the Task table do not determine whether its records are included during installation.

B: Having an automatic number counter and setting a table property do not control the inclusion of records in the application package.

D: The System Clone > Exclude Tables list pertains to cloning operations and does not affect application installation.

For detailed guidance on including table records in application deployments, refer to the official ServiceNow documentation:

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.

In ServiceNow, to create a module that directs users to a Record Producer (a simplified form for creating records), you should use the "URL (from Arguments)" Link Type. This configuration allows you to specify a direct link to the Record Producer.

Steps to Configure:

Navigate to Module Creation:

Go to the Application Menu where you want to add the module.

Click on "Edit Application Menu" and then "New Module."

Set Link Type:

In the module's configuration, set the Link Type to "URL (from Arguments)."

Define the URL:

In the Arguments field, provide the URL to the Record Producer. The URL typically follows this pattern:

arduino

CopyEdit

servicenow_instance_url/com.glideapp.servicecatalog_cat_item_view.do?sysparm_id=record_producer_sys_id

Replace servicenow_instance_url with your instance's URL and record_producer_sys_id with the sys_id of the Record Producer.

Explanation of Other Options:

HTML (from Arguments): Used to display custom HTML content. Not suitable for linking directly to Record Producers.

Content Page: Used to display predefined content pages within ServiceNow. Not applicable for direct Record Producer links.

Script (from Arguments): Allows execution of a script to determine the module's behavior. This is more complex and unnecessary for simply linking to a Record Producer.

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.

ServiceNow supports publishing an application to an application repository, an Update Set, or the ServiceNow Store. These methods allow the application to be installed on other instances or shared with other users.

Publish an application to the application repository

4 Ways to Publish a ServiceNow Application

Publish applications to the ServiceNow Store

Application Properties let developers expose configurable values (via system properties), so behavior can be changed without altering code.

From Development Handbook 4.0.4, p. 167:

“Use application properties to enable or disable features or change behavior without modifying scripts directly. This promotes modularity and flexibility.”

Application Files are ServiceNow artifacts comprising an application. An application is a group of files and data that work together to provide a service or functionality. An application file is a specific type of file that belongs to an application, such as a table, a script, a form, a business rule, a UI action, etc. Application files define the structure, logic, and interface of the application. An XML export of an application’s table records, XML exports of an application’s Update Set, and CSV files containing data imported into an application are not examples of application files, as they are data formats that can be used to transfer or store information related to an application, but not the application itself.

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.

The Application Repository is a central location for storing, managing, and distributing custom applications developed on the Now Platform.

From Developer Site > App Repo:

“The ServiceNow Application Repository stores custom applications and enables developers to distribute applications across multiple instances in their organization.”

In the Automated Test Framework (ATF) of ServiceNow, the "Impersonate" test step is used to simulate actions as a specific user. This is crucial for testing functionalities that depend on user roles, permissions, or specific user contexts.

Key Points:

Purpose: The "Impersonate" step allows the test to execute subsequent steps as if performed by the specified user, ensuring that role-based permissions and access controls are accurately tested.

Usage: To add an "Impersonate" step:

Open your test in ATF.

Click on "Add Test Step."

Select "Impersonate User."

Choose the user you want to impersonate for the test.

Considerations: Ensure that the user being impersonated has the necessary roles and permissions for the actions being tested. Additionally, be aware that impersonation affects both server-side and client-side operations during the test.

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.

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.

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

"There are two possible ways to respond to events:

- Email Notification

- Script Action" - see this quote in link below:

https://developer.servicenow.com/dev.do#!/learn/learning-plans/tokyo/new_to_servicenow/app_store_learnv2_automatingapps_tokyo_responding_to_events

Application Access settings in ServiceNow control which operations are permitted on a table by other applications. The following operations can be restricted:

Query (A) - Valid: Controls whether other applications can read (query) records from the table.

Create (B) - Valid: Determines whether other applications can add new records to the table.

Execute (C) - Incorrect: No such operation exists for Application Access.

Update (D) - Incorrect: "Update" permissions are controlled through Access Control Lists (ACLs), not Application Access settings.

To allow a module to open a form for new record insertion, the Link type should be set to “Create new record” or similar.

From Platform App Design Docs:

“Modules control navigation behavior via the Link type setting. To insert records, use the 'Create record' or 'New record' link type.”

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

In ServiceNow, a workflow context refers to a specific instance of a workflow execution. When a workflow is initiated—whether by inserting or updating a record, triggering an event, or through scripts—the system creates a workflow context. This context is derived from a particular version of the workflow and is responsible for executing the defined activities and following the specified transitions within that workflow.

Key points about workflow context:

Instance of Execution: Each time a workflow runs, a new context is created to manage that specific execution instance. This allows multiple instances of the same workflow to operate independently and simultaneously.

Execution of Activities: The context manages the progression through the workflow's activities, ensuring that each step is executed in the defined order and under the specified conditions.

Tracking and Management: Workflow contexts enable administrators to monitor the state and progress of workflow executions. They provide visibility into which activities have been completed, which are pending, and any transitions that have occurred.

For example, if a workflow is designed to handle approval processes, each time an approval is initiated, a new workflow context is created to manage that particular approval instance. This context will track the approval's progress, manage notifications, and handle any branching logic defined in the workflow.

In ServiceNow, when configuring a REST Message, the Endpoint specifies the URI (Uniform Resource Identifier) where the REST request is sent. This URI points to the resource on the external system that the REST message will interact with, whether it's to retrieve, update, create, or delete data.

Key Points:

Endpoint Definition: The Endpoint is a complete URL that includes the protocol (e.g., HTTP or HTTPS), the domain or IP address of the external server, and the specific path to the resource. For example: https://api.example.com/v1/resources.

Dynamic Endpoints: ServiceNow allows the use of variables within the Endpoint URL, enabling dynamic substitution at runtime. This is useful when the exact resource path or parameters need to be determined during execution.

Configuration in ServiceNow:

Navigate to "System Web Services" > "Outbound" > "REST Message."

Create a new REST Message or select an existing one.

In the REST Message record, define the Endpoint URL in the "Endpoint" field.

Example Scenario:

If you are integrating ServiceNow with an external ticketing system to retrieve incident data, the Endpoint might be something like https://api.ticketingsystem.com/incidents/{incident_id}, where {incident_id} is a placeholder that gets replaced with the actual incident ID at runtime.

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.

 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

In ServiceNow, when an event is generated using the gs.eventQueue() method, the system can respond in several ways:

B. Email Notification: Events can trigger email notifications. By associating an event with a notification, the system can send emails to specified recipients when the event occurs.

E. Script Action: Script Actions are server-side scripts that execute in response to events. They allow developers to define custom behaviors that should occur when specific events are fired.

The other options are not appropriate responses to events generated by gs.eventQueue():

A. UI Policy: UI Policies are used to dynamically change the behavior of fields on forms in the user interface and are not triggered by events.

C. Client Script: Client Scripts run on the client side (in the user's browser) and are not directly triggered by server-side events.

D. Scheduled Script Execution (Scheduled Job): Scheduled Jobs are scripts that run at specified times or intervals and are not triggered by events.

For more detailed information, refer to the official ServiceNow documentation on Responding to Events.

In ServiceNow, the Event Registry is a table that contains a record for every event recognized by the system. It allows ServiceNow to respond when these events are generated. By registering events, the system can automate activities such as triggering notifications or executing script actions when specific events occur. Therefore, the correct answer is A.

The other options are not accurate descriptions of the Event Registry:

B. The Event Log which lists all Events that have been generated: This describes the Event Log, not the Event Registry.

C. A Workflow which is launched every time an Event is generated; used to debug Events: This is not how the Event Registry functions.

D. The method used in server-side scripts to generate Events and pass parameters: This describes the gs.eventQueue() method, not the Event Registry.

For more detailed information, refer to the official ServiceNow documentation on the Event Registry.
