Question 130
A Databricks RAG or agent workflow behaves unexpectedly: An agent promotion script overwrites the only model file without retaining the prior validated artifact. Which diagnostic check has the highest value?
Explanation
Correct Answer
Correct. MLflow-logged models can be registered in Unity Catalog, with governed names, permissions and traceable version lineage. In the given situation — An agent promotion script overwrites the only model file without retaining the prior validated artifact. — the targeted diagnose action is: Inspect UC model names, signatures, version metadata, lineage and relevant ACLs. 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 deployment manifests, tests, aliases, index versions and rollback dependency matrix. This action primarily relates to CI/CD pipelines for retrieval and agent components: Production promotions should test source index, prompt, model packaging and tool behavior independently before release. However, the described case — An agent promotion script overwrites the only model file without retaining the prior validated artifact. — is testing Unity Catalog registered model version and privileges. 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 query embedding provenance, index schema, similarity results and selected context window. This action primarily relates to Vector Search retrieval workflow and query integration: Semantic retrieval uses an embedding model to query a compatible index, returns ranked passages and metadata for grounded generation. However, the described case — An agent promotion script overwrites the only model file without retaining the prior validated artifact. — is testing Unity Catalog registered model version and privileges. 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 serving endpoint permissions, token path, user/app identity and downstream Unity Catalog access. This action primarily relates to Model Serving endpoint permissions and caller identity: Access to a serving endpoint is governed by workspace rights and identity; caller authorization is distinct from data-source permissions. However, the described case — An agent promotion script overwrites the only model file without retaining the prior validated artifact. — is testing Unity Catalog registered model version and privileges. 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.
