What is API-Led connectivity described as in MuleSoft's enterprise architecture?

• A. A data replication mechanism
• B. A monolithic integration strategy
• C. An approach that layers APIs to enable reuse and composition
• D. A real-time streaming-only protocol

Answer: (C)

API-Led connectivity in MuleSoft is about exposing backend capabilities as layered APIs, so they can be reused and combined in flexible ways. In practice, this means organizing APIs into distinct layers: System APIs connect to core systems and encapsulate security and connectivity; Process APIs orchestrate and shape data, implementing business logic without tying it to any one consumer; Experience APIs tailor data for specific user experiences or channels. This structure lets teams reuse the same System APIs across many processes and experiences, and enables new capabilities to be composed by linking APIs rather than building new integrations from scratch. It also supports governance, versioning, and security consistently across the landscape. It’s not about data replication, not a monolithic approach, and not restricted to real-time streaming.
