Functional and nonfunctional integration requirements
Separate what an integration does (routing, transformation, orchestration) from how well and under what conditions it does it (availability, reliability, manageability, access protection), and match each requirement with the evidence and Anypoint mechanism that satisfies it.
Differentiate between functional and non-functional requirements for integration solutions.

What the exam expects
- Classify a requirement as functional (what the integration does) or nonfunctional (a quality or constraint on how it runs).
- Recognize routing, data transformation and orchestration as functional concerns, and availability, reliability and manageability as nonfunctional ones.
- Treat access and security rules as nonfunctional requirements that runtime policies enforce, separate from the API's business function.
- Decide what evidence each requirement needs, so that proof of one kind is not accepted as proof of the other.
Functional requirement: the behavior the integration must deliver, defined by the API developer and owner. Nonfunctional requirement: a quality such as availability, reliability, manageability or security that governs how that behavior is delivered. Orchestration: the sequence of business actions an integration performs. Policy: a regulation applied to an API instance in API Manager without changing the implementation (ESB requirements, Policies overview).
