An insurance carrier plans to launch a new product for various types of Recreational Vehicles...

In the Guidewire Page Configuration Framework (PCF), the primary goal for handling polymorphic data—such as a base Recreational Vehicle entity with various subtypes—is to maximize code reuse while providing a dynamic user experience. According to theInsuranceSuite Developer Fundamentalscourse, the best practice for this scenario involves a "Master-Detail" design pattern utilizingModal PCFs.

The first step (Option D) is to create a primaryDetail View (DV). This DV acts as the foundation for the UI and contains all the fields that are shared across all RV types, such as PurchaseDate, Price, and Model. By centralizing these common fields, the developer ensures that any global changes to RV data (like adding a "Condition" field) only need to be made in one place, rather than across multiple fragmented pages.

The second step (Option E) addresses the unique properties of each RV type. Rather than cluttering the main DV with every possible field and using complex "visible" expressions (which is what Option C suggests and is discouraged due to performance and maintenance overhead), developers should use anInput Set Refwith theModeproperty set. Each specific RV type (e.g., Boat, Motorcycle) has its own separate Input Set. At runtime, the Guidewire application looks at the RV type of the current object and automatically renders the corresponding Input Set. This "Modal" approach is the standard architectural way to handle subtypes in PolicyCenter and ClaimCenter. Options A, B, and F are incorrect because they either introduce unnecessary navigation complexity or fail to leverage the built-in dynamic rendering capabilities of the PCF framework.
