Which module is responsible for the overall infrastructure of the FHIR specification?

• A. Foundation Framework
• B. Foundation module
• C. Security and Privacy Module
• D. Implementation Support Module

Answer: (B)

The concept being tested is which part of the FHIR structure provides the shared, underlying framework that everything else is built on. The Foundation module defines the core data model and building blocks that all FHIR resources rely on—the base Resource type, Element, BackboneElement, and the common data types and constraints. These foundations establish how data is modeled, serialized, and how metadata and constraints are represented, providing a consistent infrastructure for the entire specification.

The other modules address specific concerns rather than the overall structure: the Security and Privacy Module focuses on access control, consent, auditing, and privacy safeguards; the Implementation Support Module offers guidance for implementing FHIR, conformance, packaging, and tooling. The option labeled Foundation Framework isn’t a standard module in the official spec. So the Foundation module is the best answer because it underpins the entire FHIR specification’s architecture.
