The two most common ways to expose your application to an external system are to leverage the Pega API (B) and to create a web service with the Service wizard (D). The Pega API provides a set of out-of-the-box RESTful endpoints for performing operations within the Pega Platform. The Service wizard simplifies the creation of SOAP or REST services, enabling external systems to interact with Pega applications.References: Pega Community documentation on Pega API and Service wizard.

A keyed data page is best used when a user selects a replacement part from a long list that seldom changes (B). Keyed data pages are designed to efficiently manage large amounts of data that do not change frequently by loading data specific to a key (like a part ID). This improves performance by caching the data and reducing the need to frequently query the source system for the same data.References: Pega Community documentation on data pages and caching strategies

Connectors establish a link to a service on another system (B). They are designed to communicate with external systems, such as sending a request to a web service or a REST service, and handle the response within a Pega application. This capability is part of Pega's integration features and enables the application to interact with multiple systems across different platforms.References: Pega Community documentation on connectors and integration.
