Question 280
What long-term control is MOST directly justified by this Databricks GenAI situation? A deployed chatbot silently uses a different embedding model from the retrieval index built in development.
Explanation
Correct Answer
Correct. A deployable RAG application needs tracked model code, retriever config, embedding model, dependency versions, signature and example input. In the given situation — A deployed chatbot silently uses a different embedding model from the retrieval index built in development. — the targeted safeguard action is: Record source index versions and external dependencies with the model artifact to support rollback. It preserves an enduring engineering or governance boundary after the current issue is fixed.
Incorrect Answers
Not the strongest safeguard choice for this specific question. Never rely on interactive notebook state or unpinned runtime packages when promoting a served model. 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 deployed chatbot silently uses a different embedding model from the retrieval index built in development. — is testing RAG production bundle metadata and dependencies. It does not directly establish the safeguard outcome or constraint that the question requires; it may still be useful in a different stage or incident.
Not the strongest safeguard choice for this specific question. Do not equate registering a model with approving its business safety or access to all governed tables. This action primarily relates to Unity Catalog registered model version and privileges: MLflow-logged models can be registered in Unity Catalog, with governed names, permissions and traceable version lineage. However, the described case — A deployed chatbot silently uses a different embedding model from the retrieval index built in development. — is testing RAG production bundle metadata and dependencies. It does not directly establish the safeguard outcome or constraint that the question requires; it may still be useful in a different stage or incident.
Not the strongest safeguard choice for this specific question. Require approval/rollback for prompt and index changes that alter user-facing model behavior. 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 — A deployed chatbot silently uses a different embedding model from the retrieval index built in development. — is testing RAG production bundle metadata and dependencies. It does not directly establish the safeguard outcome or constraint that the question requires; it may still be useful in a different stage or incident.
