CCAR-F Agentic Architecture and Orchestration Practice Question
An architect is designing a system where Claude must handle complex multi-step customer inquiries. The current implementation uses a single prompt, but it often fails on high-reasoning tasks. Which agentic pattern should be implemented to allow a primary model to decompose the user's request into sub-tasks for specialized worker agents?
⚠ Common exam trap
Candidates often try to force a single model to handle too many responsibilities, leading to context bloat and poor performance, rather than delegating tasks via the Orchestrator-Workers pattern.

Correct answer & explanation
✓
The Orchestrator-Workers Pattern
The Orchestrator-Workers pattern is essential for high-complexity tasks that require decomposition. By using a central orchestrator to plan and delegate sub-tasks to specialized workers, the system avoids context dilution and prevents the model from being overwhelmed by too many instructions at once. This pattern enhances reliability and allows for more granular error handling and parallel execution of independent sub-tasks in a production environment.

- ✗
The Router Pattern
Why it's wrong here
Routing focuses on directing a query to a single specialized prompt or agent rather than breaking a single request into multiple sub-tasks. It is best used when a query fits into a clear category, but it lacks the decomposition and synthesis capabilities required for the complex, multi-step scenarios described here.
- ✓
The Orchestrator-Workers Pattern
Why this is correct
This pattern allows a primary agent to analyze a complex request and dynamically generate a plan consisting of multiple sub-tasks. Each worker agent handles a specific portion of the plan, and the orchestrator synthesizes their outputs into a final response, making it ideal for high-reasoning tasks requiring structural decomposition.
- ✗
The Parallelism Pattern
Why it's wrong here
Parallelism involves running multiple instances of a model or different models simultaneously to generate diverse outputs or check for consistency. While it can be part of an orchestration strategy, it does not inherently provide the logic for task decomposition and management that the Orchestrator-Workers pattern provides for complex inquiries.
- ✗
The Evaluator-Optimizer Pattern
Why it's wrong here
This pattern uses a feedback loop where one model generates a draft and another model critiques it to drive iterative improvements. It is highly effective for creative writing or code generation but does not address the need to break down a multifaceted customer inquiry into distinct, manageable operational sub-steps.
