Your question is Designing an LLM ML Architecture. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe how you would design an ML architecture for a Databricks system that uses LLMs, including key components, data flow, and deployment considerations.
Treat this as a practical system design discussion. Explain your assumptions, distinguish offline and online paths, and address retrieval, generation, evaluation, monitoring, cost, security, and failure recovery. Use Databricks components where appropriate, including Unity Catalog, Delta Lake, Mosaic AI, Vector Search, MLflow, Feature Store, and Model Serving.
