Service Oriented Architecture is primarily based on what?

• A. A collection of functions or services that communicate with one another
• B. A monolithic design with a single deployment
• C. Independent desktop applications
• D. A centralized database architecture only

Answer: (A)

SOA centers on building software as a set of services that interact by exchanging messages. Each service performs a specific business function and offers a well-defined interface, so different services can be reused and combined to support larger workflows. This distributed approach means services can be developed, deployed, and scaled independently and communicate over a network using standard protocols. That is why the option describing a collection of functions or services that communicate with one another is the best fit. It contrasts with a monolithic design (everything built and deployed together), independent desktop applications (which aren’t designed to interoperate as services), or a centralized database-only architecture (which ignores the distributed, service-based nature of SOA).
