Service-Oriented Integration creates a catalog of SOA Services that expose capabilities from
existing back-end systems. What are the three types of capabilities that the SOA Services
expose?

A.
existing business processes

B.
existing management and monitoring functionality

C.
existing business functionality

D.
existing data entities

E.
existing application programming interfaces (APIs)

Explanation:
The SOA Service needs to expose process, functionality, and data that is usable in
a broader context than the source of the capability was designed to meet. Therefore, creating a
SOA Service usually entails
some amount of aggregation, transformation, or expansion of existing capabilities
provided by the source systems.
Note on D: Each existing application contains its own data model and data formats. This
proliferation of data models and data formats is exacerbated by the fact that a single
enterprise entity (e.g. customer, product, order) frequently has data elements stored in
multiple existing applications. To be successful at exposing existing data via SOA
Services, the integration approach must manage this complexity.
