CAD Exam Dumps - ServiceNow Certified Application Developer Questions and Answers

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.

When creating a table, the Create module field allows you to automatically create a module for the table in the application menu. The default behavior of the new module is to display a list of all records from the table. This can be changed later by editing the module properties and specifying a different link type, such as form, URL, or script.

The Allow configuration Application Access option determines whether users can configure the application tables, such as adding or modifying fields, views, or indexes. The following is true for a table with the Allow configuration option selected:

Out of scope applications can create Business Rules for the table. This is true because the Allow configuration option grants access to the table configuration to any user who has the admin or personalize_dictionary role, regardless of the application scope. This means that users can create Business Rules, which are server-side scripts that run when a record is displayed, inserted, updated, or deleted, for the table from any application.

The following are not true for a table with the Allow configuration option selected:

Only the in scope application’s scripts can create Business Rules for the table. This is false because the Allow configuration option does not restrict the creation of Business Rules to the in scope application, as explained above.

Any user with the application’s user role can modify the application’s scripts. This is false because the Allow configuration option does not grant access to the application scripts, such as client scripts or script includes, to any user who has the application’s user role. To modify the application scripts, users need to have the admin role or the application’s admin role.

Out of scope applications can add new tables to the scoped application. This is false because the Allow configuration option does not allow out of scope applications to add new tables to the scoped application. To add new tables to a scoped application, users need to have the admin role or the application’s admin role and be in the application scope. References: Application Access, Business Rules

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

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

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

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

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

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

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

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.

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

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

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

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

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