ITPEC FE Morning April 2019 Question 63
ITPEC FE Morning April 2019 — Question 63 of 80
Service-Oriented Architecture (SOA) — building a system by treating software functions as independent, reusable components called services and combining them.
SOA structures an application as a collection of loosely coupled services that communicate through standardized interfaces (e.g., APIs, message queues). Each service encapsulates a specific business function and can be reused across different systems.
Correct answer: a) — A concept of constructing a system by considering the software functions as components called services and combining them.
Why not the others:
- b) describes SFA (Sales Force Automation) — using IT to boost sales efficiency and customer satisfaction
- c) describes BPR (Business Process Re-engineering) — radically redesigning business processes to improve cost, quality, service, and speed
- d) describes BPO (Business Process Outsourcing) — outsourcing non-core operations to focus resources on core business
Key rule: SOA = services as building blocks; think of it as microservices' predecessor — modular, reusable, loosely coupled components combined to form a system.
