NEW QUESTION 86
What MuleSoft API-led connectivity layer is intended to expose part of a backend database without business logic?

A. System layer
B. Data layer
C. Experience layer
D. Process layer

Answer: A

Explanation:
Correct answer is System layer
System APIs provide a means for insulating the data consumers from the complexity or changes to the underlying backend systems.
MuleSoft recommends three-layered approach to API-led connectivity, highlighting the three layers:
* System APIs
* Process APIs
* Experience APIs
System APIs are the core systems of record underlying core systems of record (e.g. ERPs, key customer and billing systems, databases, etc.). Process APIs allow you to define a common process which the organization can share, and these APIs perform specific functions, provide access to non-central data, and may be built by either Central IT or Line of Business IT. And finally, the Experience APIs are the means by which data can be reconfigured so that it is most easily consumed by its intended audience, all from a common data source.
The three-layered structure allows for a seamless flow of data from systems of record to new experiences, and allows for reusability of assets rather than point to point connections. This approach provides a distributed and tailored approach to architecture, greater flexibility through loose coupling, and deeper operational visibility into what is being built.
