CAD Certified Application Developer - ServiceNow Questions and Answers

The following is true for GlideUser (g_user) methods:

Can be used in Client Scripts, UI Policies, and UI Actions. This is true because GlideUser (g_user) methods are part of the client-side scripting APIs that provide information about the current user and the user’s preferences. Client Scripts, UI Policies, and UI Actions are all types of client-side scripts that run in the web browser and manipulate the user interface.

The following are not true for GlideUser (g_user) methods:

Can be used in Client Scripts and UI Policies only. This is false because GlideUser (g_user) methods can also be used in UI Actions, which are another type of client-side scripts that can be triggered by a user’s click on a button, link, or choice.

Can be used in Business Rules only. This is false because GlideUser (g_user) methods cannot be used in Business Rules, which are server-side scripts that run on the ServiceNow platform and manipulate the database. Business Rules use a different API to access the current user information, which is GlideSystem (gs).

Can be used in Business Rules, and Scripts Includes. This is false because GlideUser (g_user) methods cannot be used in Business Rules or Script Includes, which are both server-side scripts. Script Includes are reusable units of code that can be called from any server-side script. Script Includes also use GlideSystem (gs) to access the current user information. References: Client-Side Scripting APIs, GlideUser, Business Rules, Script Includes

Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. By selecting the Allow access to this table via web services option, you can enable other application scopes to access your data tables using web services, such as SOAP or REST. However, the user performing the query via web services must have the correct permissions to access the table’s records. The user must have the appropriate roles and access controls to perform the operations on the table, such as create, read, write, or delete.

The other statements are not true when this option is selected. This option does not restrict the ability to delete records via web services, nor does it allow records to be always read. The access to the records depends on the user’s permissions and the web service method. This option also does not restrict access only to SOAP web services, but applies to both SOAP and REST web services. Finally, this option is not the only way to enable web service access to the table’s records. Even when this option is not selected, users with the correct permissions can use web services to access the table’s records, as long as they specify the application scope in the web service request.

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.”

A Module Link type defines how the module opens in the content pane when the user clicks on it in the navigation pane1. The URL (from Arguments) link type allows you to specify a URL that opens the Application Properties page for the selected application2. The URL can include arguments that are evaluated at runtime, such as the application name or scope3.

In ServiceNow, Business Rules are server-side scripts that execute whenever a record is inserted, updated, deleted, or queried. However, certain actions can be configured without writing any script, using the Business Rule's user interface options.

The primary actions that can be configured without scripting are:

Set field values: This allows administrators to specify new values for fields when the Business Rule conditions are met. This is configured in the "Actions" tab of the Business Rule form, where specific fields and their desired values can be set without any scripting.

Add message: Administrators can configure a message to be displayed to the user when the Business Rule executes. This is done by selecting the "Add message" checkbox and providing the desired message text.

Options C (Set field values and write to the system log) and D (Set field values and generate an event) would require scripting. Writing to the system log involves using server-side APIs like gs.log(), and generating an event requires calling event generation methods—both necessitate scripting.

For more detailed information, refer to the official ServiceNow documentation on Business Rules:

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 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]

A spoke is a scoped application that contains flow actions that can be used in Flow Designer. Spokes allow developers to create reusable actions that can be shared across applications and instances.

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

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 ServiceNow, when importing data from external sources, the platform utilizes Import Sets to stage the data before transforming it into target tables. The mechanism that defines how data from the Import Set fields map to the fields in an existing ServiceNow table is called a Transform Map.

Transform Map: A Transform Map is a set of field mappings that determine the relationships between fields in an Import Set and fields in an existing ServiceNow table. It allows administrators to define how data should be transformed and inserted into the target table.

servicenow.com

Business Service Management Map: This is not related to data import processes. It pertains to visual representations of business services and their dependencies.

Schema Map Relationship Builder: The Schema Map provides a graphical representation of tables and their relationships within the database schema but does not handle data import mappings.

Data Sources: Data Sources define the origin of the data being imported (e.g., files, JDBC connections) but do not determine the field mappings between Import Sets and target tables.

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

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.”

In ServiceNow, to include data from another table within a form, the Reference field type is utilized. A Reference field creates a relationship between the current table and another table by storing a reference to a record in the target table. This allows users to select a record from the referenced table and display related information seamlessly within the form.

A. Use the Date field type: This is incorrect. The Date field type is designed to store date values and does not facilitate referencing records from other tables.

B. Use the Phone Number field type: This is incorrect. The Phone Number field type is intended for storing phone number data and does not support referencing other table records.

C. Use the String field type: This is incorrect. The String field type stores text data and does not inherently provide functionality to reference records from other tables.

D. Use the Reference field type: This is correct. The Reference field type is specifically designed to create a link to a record in another table, enabling the incorporation of related data into the form.

For example, in the Incident table, the "Caller" field is a reference to the User [sys_user] table, allowing the selection of a user as the caller for the incident. This setup ensures data consistency and leverages existing records without data duplication.

For more detailed information, refer to the official ServiceNow documentation on Reference Fields.

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

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.

 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

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]

Delegated Development is intended to let administrators grant controlled development permissions to non-admin developers for a specific scoped application. Within that model, admins can allow delegated developers to work on application artifacts and administration tasks that are still limited to the application scope. One of the permitted areas is managing security artifacts, which includes creating and maintaining Access Controls (ACLs) and related security configuration for the application’s tables and resources. That aligns directly to option C. Administrators can also grant the permission to delete the scoped application, which aligns to option D and is treated as a high-impact capability that is explicitly controlled by delegated development permissions. By contrast, option A is not valid because delegated development is for scoped applications and does not grant authority to develop or deploy global applications. Option B is not a delegated development permission category; coalesce configuration is part of import/set-up behavior and is not represented as a delegated developer permission in the application development permission set.

"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:

In ServiceNow, UI Actions are elements such as buttons, links, and context menu items that allow users to perform actions on records or lists. The three valid UI Action types are:

1. List Banner Button (Option A)

Description: A button that appears in the list view header, allowing users to trigger an action affecting multiple records at once.

Example: A "Bulk Approve" button that processes selected records.

2. Form Button (Option B)

Description: A button that appears on a form, allowing users to trigger actions related to the current record.

Example: A "Submit for Approval" button on an incident form.

3. Record Navigation Button (Option D)

Description: A button that helps users navigate between related records.

Example: A "Go to Parent Record" button that redirects users to a linked record.

Incorrect Options:

Form Choice (Option C):

Not a UI Action type. Choices are typically used in choice fields (dropdowns) rather than UI actions.

List Choice (Option E):

Not a valid UI Action type. Similar to "Form Choice," it pertains to field options rather than UI elements.

Workflow Action (Option F):

Workflows are process automation tools, not UI Actions. They are not directly related to buttons or links that users interact with.

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

The statement that is true for this script fragment is that the method returns true if the currently logged in user has the x_my_app_user role or the admin role. The g_user.hasRole() method is a client-side method that checks whether the current user has a specified role or set of roles. If no role is specified, it returns true if the user has any role. If one or more roles are specified, it returns true if the user has any one of the specified roles. However, this method always returns true if the user has the admin role, regardless of the role parameter. Therefore, in this case, the method returns true if the user has either the x_my_app_user role or the admin role. Reference: User Object Cheat Sheet, Checking user permissions

ServiceNow provides several methods for developers to publish and share applications once they are ready for distribution. The supported methods include:

Publish to an application repository: This method allows developers to publish their applications to a centralized repository, enabling easy distribution and installation across multiple ServiceNow instances. The application repository serves as a hub where applications can be stored and accessed by other instances.

snowunderground.com

Publish to the ServiceNow Store: Developers can submit their applications to the ServiceNow Store, a marketplace where applications are reviewed, certified, and made available to all ServiceNow customers. Publishing to the Store involves a certification process to ensure the application meets ServiceNow's standards.

support.servicenow.com

Publish to an update set: An update set is a container for capturing configuration changes in ServiceNow. Developers can publish applications to an update set, which can then be moved between instances, allowing for the transfer of application configurations and customizations.

servicenow.com

Options A (Publish to a spreadsheet), D (Publish to a local USB device), and F (Publish to a local drive) are not supported methods for publishing applications in ServiceNow. These options do not align with the platform's mechanisms for application distribution and deployment.

https://developer.servicenow.com/dev.do#!/learn/courses/tokyo/app_store_learnv2_flowdesigner_tokyo_flow_designer/app_store_learnv2_flowdesigner_tokyo_notifications_in_flow_designer/app_store_learnv2_flowdesigner_tokyo_inbound_email_and_flows

"By default, the system generates a watermark label at the bottom of each notification email to allow matching incoming email to existing records." https://docs.servicenow.com/bundle/tokyo-servicenow-platform/page/administer/notification/concept/c_WorkingWithWatermarks.html

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.

A transform map determines the relationships between fields displaying in an Import Set table and fields in an existing ServiceNow table, such as the Incidents or Users table.

https://docs.servicenow.com/bundle/tokyo-platform-administration/page/administer/platform-events/reference/r_ScriptActions.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]

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

In ServiceNow, the admin role includes all other roles implicitly. So if a user has admin, g_user.hasRole('any_role') returns true.

From ServiceNow Docs – g_user API:

“The hasRole() method returns true if the user has the specified role or is an admin.”

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, 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.

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

https://docs.servicenow.com/bundle/tokyo-application-development/page/build/applications/task/set-RCA-level.html

ServiceNow notifications can sometimes be triggered close together for the same record and the same recipients, which can lead to redundant or conflicting messages. To control this, the Notification record includes a Weight field. ServiceNow documentation explains that when multiple notifications are generated for the same target table record and the recipients overlap, the system compares the notifications using the Weight value and sends only the notification with the highest weight. This allows administrators and developers to prioritize the most important notification when multiple are eligible to fire. A common example in the documentation is when an incident is updated (triggering an “commented” notification) and then closed shortly after (triggering a “closed” notification). If both would go to the same user, ServiceNow will select the one with the higher weight, ensuring users receive the most relevant final message instead of multiple emails. This behavior is the intended purpose of Weight: reduce notification noise and prevent conflicts by giving precedence to the highest-weight notification.

https://docs.servicenow.com/bundle/tokyo-application-development/page/script/server-scripting/concept/c_ServerScripting.html

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.

Flow Designer is a graphical tool that allows users to automate processes in ServiceNow without coding. The following are supported by Flow Designer:

Call a subflow from a flow. This is a feature that allows users to invoke a subflow, which is a reusable unit of logic, from a flow. This can help simplify complex flows and avoid duplication of logic.

Use Delegated Developer. This is a feature that allows administrators to delegate the development and maintenance of flows and actions to users who are not administrators. This can help distribute the workload and empower non-admin users to create automations.

Run a flow from a MetricBase Trigger. This is a feature that allows users to trigger a flow based on a MetricBase query, which is a way of analyzing time-series data in ServiceNow. This can help automate actions based on data trends and patterns.

The following is not supported by Flow Designer:

Test a flow with rollback. This is not a feature of Flow Designer, but of Automated Test Framework (ATF), which is a tool that allows users to create and run automated tests on ServiceNow applications and features. ATF supports testing flows with rollback, which means reverting any changes made by the flow during the test execution. References: Flow Designer, Automated Test Framework

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.

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]

 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, the "Allow access to this table via web services" option within the Application Access settings determines whether the table can be accessed through web service protocols, such as REST and SOAP. When this option is selected, it permits the table to be accessible via web services; however, it does not override existing permissions. The user or system making the web service request must still have the appropriate permissions (such as roles and access controls) to perform operations on the table's records.

Option A: Incorrect. If the "Allow access to this table via web services" option is not selected, the table is not accessible via web services, regardless of user permissions.

Option B: Correct. Enabling this option allows the table to be accessed via web services, but the user must have the correct permissions to access the table's records.

Option C: Incorrect. This option applies to all web service protocols, including both SOAP and REST.

Option D: Incorrect. This option controls overall web service access to the table; specific operations (create, read, update, delete) are governed by user permissions and access controls.

In ServiceNow, a Record Producer is a specific type of catalog item that enables users to create task-based records through a simplified interface.

servicenow.com

To create a module that directs users to a Record Producer UI:

Link Type Selection: Choose "URL (from Arguments:)" as the Link Type. This option allows you to specify a direct URL, enabling the module to open the desired Record Producer interface.

URL Configuration: In the "Arguments" field, input the URL that points directly to the Record Producer. This URL typically follows the format:

/record_producer.do?sys_id=

Replace with the actual sys_id of the Record Producer you intend to open.

By configuring the module this way, users accessing it will be presented with the Record Producer's user-friendly interface, facilitating the creation of new records without navigating through the standard form UI.

Flow Designer is a no-code platform capability that lets you automate business processes in a single drag-and-drop design environment. Some of the features of Flow Designer are:

Add stages to a flow: You can define the stages of a flow to track its progress and status. Stages can be used to group actions, subflows, and conditions into logical units.

Call a flow from another flow or subflow: You can reuse existing flows or subflows by calling them from another flow or subflow. This allows you to modularize your automation and avoid duplication of logic.

Test a flow using the “Run as” feature: You can test a flow using the “Run as” feature to specify the user context and input parameters for the flow execution. This helps you to verify the functionality and performance of your flow before publishing it.

For example, Open is a module under the Problem application menu that opens a list of problem records. Modules are the second level navigation options for applications.

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.

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, Access Controls (ACLs) are used to manage permissions for various database operations on tables and their records. The primary operations that can be controlled include:

Create:

Description: Permission to insert new records into a table.

Control: ACLs can be defined to allow or deny users the ability to create records based on roles, conditions, or scripts.

Update:

Description: Permission to modify existing records in a table.

Control: ACLs can restrict who can update records, ensuring that only authorized users can make changes.

Other Operations:

Read: Controls the ability to view records in a table.

Delete: Manages the permission to remove records from a table.

Incorrect Options:

Execute: Not a standard database operation controlled by ACLs in ServiceNow.

Query: While querying is part of the read operation, ACLs specifically control the read access rather than the query process itself.

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

In Flow Designer, the unit that packages a set of related, reusable automation capabilities for a particular integration or application area is called a Spoke. A spoke is a scoped application that contains prebuilt actions, subflows, and supporting components designed to work together for a specific system, application, or record type. This structure helps developers and implementers reuse automation logic without rebuilding the same steps repeatedly, and it provides a governed way to distribute automation content. An Action is an individual reusable operation inside Flow Designer, not the container application. A Flow is an automation definition that runs based on a trigger, not a package of actions. “Bundle” is not the standard Flow Designer packaging term for these scoped sets of actions. Therefore, the correct scoped application type that contains tailored actions is a Spoke.

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.

Enabling “Allow access to this table via web services” allows authenticated users with proper roles to access this table via REST/SOAP APIs.

From Development Handbook 4.0.4, p. 191:

"This setting allows web service access to a table, but still requires that users have appropriate roles and permissions through ACLs."

Thus, access isn’t automatic — proper access controls still apply.

The following are debugging strategies for client-side scripts, which run in the web browser and manipulate the user interface:

g_form.addInfoMessage(). This is a client-side API that displays an information message at the top of the form.

Field Watcher. This is a debugging tool that displays the current and previous values of one or more fields on a form.

jslog(). This is a client-side API that writes a message to the browser console.

The following is not a debugging strategy for client-side scripts, but for server-side scripts, which run on the ServiceNow platform and manipulate the database:

gs.log(). This is a server-side API that writes a message to the system log. References: Client-Side Scripting APIs, Debugging Client Scripts

In the Application Navigator, visibility is evaluated at both the application menu level and the module level. A module can specify roles in its Roles field, but when that module Roles field is empty, the module does not add additional role requirements by itself. Instead, the user must still be able to see the application menu that contains the module. That means the effective gate becomes the application menu’s access configuration (including any required roles on the application menu). As a result, the module is visible to users who already have access to the application menu, because the module is not restricting access further. This behavior supports clean navigation design: define broad access at the application menu level, and only add module-level roles when you need to hide specific modules within an otherwise visible application menu. Options like “snc_internal” or “users with no roles” are not universally correct because module visibility is not determined by those conditions alone. The key rule is: if module Roles is empty, application menu access controls whether users can see the module.

ServiceNow is optimized for building applications that manage structured data in tables and provide consistent user experiences through lists and forms. A core reason to develop on the platform is when the solution naturally fits the record-based model: users create, review, and update records through forms, and those records drive reporting, auditing, and process automation. That makes option C a direct match to how ServiceNow applications are designed and delivered. Another primary platform strength is workflow automation, including Flow Designer, approvals, task orchestration, notifications, and integration actions that coordinate work across teams and systems. If the solution requires repeatable, governed process automation, option D aligns with the platform’s purpose and capabilities. In contrast, “multimedia features” is not a platform driver for application development; while media can be displayed, it is not the typical reason to choose ServiceNow. Similarly, requiring low-level programming libraries is generally a mismatch, since ServiceNow development focuses on platform APIs and configuration patterns rather than direct access to low-level system libraries.

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

"You must first select read access to grant any other API record operation." https://docs.servicenow.com/bundle/tokyo-application-development/page/build/applications/reference/r_TableApplicationAccessFields.html

The Application Access configuration fields control the access level for an application and its tables. The following Application Access configuration fields are not available if the Can read configuration field is not selected:

Can create. This field determines whether users can create records on the application tables.

Can update. This field determines whether users can update records on the application tables.

Can delete. This field determines whether users can delete records on the application tables.

These fields are not available because they depend on the Can read field, which determines whether users can view records on the application tables. If users cannot read records, they cannot create, update, or delete them either.

The following Application Access configuration fields are available regardless of the Can read configuration field:

All access to this table via web services. This field determines whether users can access the application tables using web services, such as REST or SOAP.

Allow configuration. This field determines whether users can configure the application tables, such as adding or modifying fields, views, or indexes. References: Application Access, Certified Application Developer (CAD) Learning Path

Update sets are designed to capture configuration changes while an update set is In progress. Marking an update set Complete is a control point that indicates you are done collecting changes into that set, typically because it is ready to be moved, reviewed, or committed. After completion, the expected and documented practice is to create a new update set for any additional work. This preserves the integrity of the completed set as a stable package of changes and supports clean promotion, troubleshooting, and rollback planning. Deleting the completed update set is not the recommended workflow and can result in losing the historical packaging of captured updates. Modifying a completed update set directly is also not the standard approach because completion is used to prevent accidental addition of further changes and to keep the set consistent for migration. “Reverting to In progress” is not the normal supported lifecycle step for a completed update set in the context of adding more changes. Therefore, the correct approach is to start a new update set and continue development there, keeping the completed set unchanged.
