ITPEC FE Morning October 2018 Question 63
ITPEC FE Morning October 2018 — Question 63 of 80
Service-Oriented Architecture (SOA) — identifying the correct definition of SOA among related IT/business concepts.
SOA is a system architecture that exposes business process components and supporting IT infrastructure as reusable services. These services communicate through standard interfaces and can be composed into larger workflows.
Correct answer: c)
SOA provides business process components and IT infrastructure in the form of a service — this matches the standard definition.
Why not the others:
- a) Describes ERP (Enterprise Resource Planning) — integrated, cross-department management of resources.
- b) Describes SLA (Service Level Agreement) — a contract on service quality between a client and a provider.
- d) Describes BPR (Business Process Reengineering) — drastically redesigning business processes and workflows from scratch.
Key rule: SOA = architecture where functionality is packaged as services. If the definition mentions "service" as a delivery model for IT components — it's SOA. If it mentions "integrated management of resources" — ERP. If "agreement on quality" — SLA. If "drastic revision" — BPR.
