Question 210
For a Databricks GenAI application, consider this situation: A company must deploy a custom fine-tuned checkpoint with nonstandard preprocessing not offered by managed endpoints. What should the engineer implement FIRST?
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 implement action is: Evaluate a custom serving endpoint with model packaging and scaling suitable to the checkpoint. This directly meets the stated workflow constraint instead of addressing an adjacent capability.
Incorrect Answers
Not the strongest implement choice for this specific question. Use the managed Genie connector alongside a narrowly scoped custom MCP server for ticket actions. This action primarily relates to Managed versus external versus custom MCP server integration: MCP standardizes tool discovery; managed servers reduce hosting, external services need credentials and custom servers wrap bespoke actions. 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 implement outcome or constraint that the question requires; it may still be useful in a different stage or incident.
Not the strongest implement choice for this specific question. Run the supported index update/sync process and verify the indexed source identifiers reflect current Delta records. This action primarily relates to Databricks Vector Search index from governed Delta data: A vector index serves embeddings of chunked records maintained in a Unity Catalog governed Delta source table. 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 implement outcome or constraint that the question requires; it may still be useful in a different stage or incident.
Not the strongest implement choice for this specific question. Register immutable prompt versions, evaluate staging and move the approved production alias. This action primarily relates to MLflow Prompt Registry version aliases and promotion: Prompt Registry tracks immutable prompt versions with mutable aliases for staging and production, enabling change control and rollback. 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 implement outcome or constraint that the question requires; it may still be useful in a different stage or incident.
