Question 440
During a root-cause review, the team reports: A company must deploy a custom fine-tuned checkpoint with nonstandard preprocessing not offered by managed endpoints. What evidence best identifies the reason?
Explanation
Correct Answer
Correct. Databricks Foundation Model APIs offer managed access to supported models; custom serving is suitable for specialized models or control needs. In the given situation — A company must deploy a custom fine-tuned checkpoint with nonstandard preprocessing not offered by managed endpoints. — the targeted diagnose action is: Inspect required model type, deployment control, supported region, endpoint quotas and operational burden. It inspects the stage or constraint most likely to explain the observed failure before changing the system.
Incorrect Answers
Not the strongest diagnose choice for this specific question. Inspect warehouse type, runtime compatibility, endpoint status, SQL arguments and batch size. This action primarily relates to SQL ai_query for governed batch inference: `ai_query()` invokes an available serving endpoint from SQL; suitability depends on supported runtimes, endpoint and workload. However, the described case — A company must deploy a custom fine-tuned checkpoint with nonstandard preprocessing not offered by managed endpoints. — is testing Foundation Model API versus custom serving choices. It does not directly establish the diagnose outcome or constraint that the question requires; it may still be useful in a different stage or incident.
Not the strongest diagnose choice for this specific question. Inspect predict entrypoint, model artifacts, dependency environment, inputs and output serialization. This action primarily relates to MLflow pyfunc packaging for pre- and post-processing: A custom MLflow pyfunc model wraps request parsing, retriever/model invocation and output formatting inside a reproducible predict interface. However, the described case — A company must deploy a custom fine-tuned checkpoint with nonstandard preprocessing not offered by managed endpoints. — is testing Foundation Model API versus custom serving choices. It does not directly establish the diagnose outcome or constraint that the question requires; it may still be useful in a different stage or incident.
Not the strongest diagnose choice for this specific question. Inspect p95 latency, queue depth, rate limits, cost and per-version error traces. This action primarily relates to Endpoint scale concurrency and operational rollout: Serving latency and reliability depend on provisioned capacity, request concurrency, quotas and controlled rollout. However, the described case — A company must deploy a custom fine-tuned checkpoint with nonstandard preprocessing not offered by managed endpoints. — is testing Foundation Model API versus custom serving choices. It does not directly establish the diagnose outcome or constraint that the question requires; it may still be useful in a different stage or incident.
