Exam AI-500 Topic 1 Question 47 Discussion

Domain-scoped sub-orchestrators under a claims supervisor provide the clearest ownership and isolation model. Each domain can contain its own specialists and tools, so adding a new specialist affects only that domain. The supervisor becomes the explicit authority for cross-domain conflicts. Requiring every domain output to satisfy a structured contract before it is consumed downstream provides a deterministic validation boundary instead of relying on unconstrained narrative summaries. Microsoft AI-500 architecture objectives emphasize agent scopes, tool boundaries, structured interfaces, and explicit control loops. Option B gates only the final settlement and therefore allows invalid intermediate outputs to propagate. Option D deliberately leaves conflict resolution to consuming domains, which violates the requirement for a clear owner. Option A lacks a strong validation contract. C is therefore the most robust architecture. The architecture should still be validated with representative end-to-end tests, but the selected component establishes the correct structural boundary first. Microsoft ' s AI-500 blueprint consistently favors explicit scopes, interfaces, and persistence or identity boundaries over prompt-only conventions.
