Which describes the interfaces that an implementation exposes for exchange of data?

• A. SOW Statement
• B. Project Plans
• C. CapabilityStatement
• D. Product Roadmap

Answer: (C)

In FHIR, the interfaces an implementation exposes for exchanging data are described by a conformance artifact called a CapabilityStatement. This resource precisely documents what the system can do and how clients should interact with it. It specifies the available REST endpoints, the resources that are supported, the operations that can be performed (such as read, search, create, update, delete), and the data formats (like JSON or XML) the server accepts. It may also outline supported search parameters, paging behavior, and any messaging or document interactions the server supports. By publishing a CapabilityStatement, a server lets clients discover capabilities dynamically and tailor requests to what the server can actually handle, promoting interoperability.

The other options are not about technical interfaces for data exchange: a Statement of Work describes the scope of work, not how data is exchanged; project plans are management artifacts outlining timelines and milestones; and a product roadmap is a strategic plan for product evolution.
