CAD Exam Dumps : Certified Application Developer - ServiceNow

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

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.

ServiceNow provides the Schema Map as the platform feature specifically designed to display a graphical representation of how tables relate to one another. In application development, tables commonly extend other tables and also reference other tables through reference fields. The Schema Map visualizes these relationships so developers can quickly understand the structure of the data model, including parent-child extensions and reference connections. This is especially useful when you are designing an application’s data model, troubleshooting why a field appears on multiple tables, or assessing the impact of adding a new relationship. The Schema Map is not a general “graphical user interface” concept; it is a dedicated view focused on the database schema. Likewise, a “dependency view” may exist for other platform features (such as dependency relationships for services or configuration items), but it is not the standard tool used to explore table-to-table schema relationships during application development. Because the question asks for a graphical view of relationships among tables, the correct documented feature is Schema Map.
