What does the drag-and-drop interface in Lightning App Builder allow users to do?

The drag-and-drop interface in Lightning App Builder is designed to simplify the process of creating and customizing pages within the Salesforce platform. This user-friendly functionality allows users to easily arrange components on a page without the need for extensive coding knowledge. By utilizing the drag-and-drop feature, users can quickly add, remove, or reposition various elements such as reports, dashboards, and custom components, enabling them to design tailored user experiences that meet specific business needs.

The other options do not accurately reflect the primary purpose of the Lightning App Builder. Custom coding for apps involves a more complex development process that goes beyond the scope of the drag-and-drop interface. Accessing advanced AI features is not inherently part of the Lightning App Builder's functionality but rather pertains to other aspects of Salesforce. Similarly, managing Salesforce integrations typically involves settings and configurations that are handled outside of the drag-and-drop capabilities of the App Builder. Thus, the correct choice emphasizes the ease of page creation and customization as the fundamental advantage of using the Lightning App Builder.
