Correct answer: C
Concept: In service-oriented and web-based system design, four distinct concerns each map to one established standard: dynamic runtime discovery and invocation of independently offered services follows a publish-find-bind protocol; the general ability of differing platforms to exchange information correctly is called interoperability; structuring and encoding data for exchange across systems commonly uses a markup language such as XML; and modelling or specifying how a business workflow proceeds uses a process notation such as BPMN.
Application: Matching each GROUP-I problem domain to its GROUP-II technology using this reasoning:
GROUP-I problem domain | GROUP-II technology | Why it fits |
|---|---|---|
(P) Service-oriented computing | (3) Publish-find-bind | Needs a way for a service to be published, located, and invoked by a consumer at runtime. |
(Q) Heterogeneous communicating systems | (1) Interoperability | Needs the general capacity of differing platforms/technologies to exchange information correctly. |
(R) Information representation | (4) XML | Needs a common, structured, platform-neutral format for encoding data. |
(S) Process description | (2) BPMN | Needs a notation for modelling and specifying how a business workflow proceeds. |
Cross-check: Each of the four technologies is used exactly once across the four domains, and the four concerns are four genuinely distinct kinds of need — a runtime discovery-and-invocation mechanism, a general compatibility property, a data-encoding standard, and a process-modelling notation — so this one-to-one assignment is internally consistent with no overlap or reuse.
Result: Thus, the correct matching is P-3, Q-1, R-4, S-2.
