Question 450 A deployment bundle contains an agent artifact but omits the SQL retriever's connection configuration and packages a local notebook path instead. Which verification is strongest for this particular failure mode? Send a minimal valid request and invalid field-type examples through the loaded model, checking schema errors. Load the registered pipeline in a clean environment and verify vector dimensions and a known retrieval result. Install the bundle in isolated staging and run a retrieval call without accessing the author's personal workspace. Deploy to staging and inspect resolved resource names; verify production uses only production catalog IDs. ExplanationCorrect Answer C:A registered model package must carry or securely reference its runtime dependencies; notebook-local paths do not transfer automatically. Other Answers A:Install the bundle in isolated staging and run a retrieval call without accessing the author's personal workspace. B:Install the bundle in isolated staging and run a retrieval call without accessing the author's personal workspace. D:Install the bundle in isolated staging and run a retrieval call without accessing the author's personal workspace.
Question 451 A team logs an MLflow model successfully but cannot find it in the approved Unity Catalog registry because it used an unqualified local registry name. Which implementation decision best restores the intended behavior? Configure the Unity Catalog registry and register using the intended catalog.schema.model three-level name with appropriate privileges. Pin deployment to an explicitly approved registered model version or governed alias and promote it only after evaluation. Capture a representative typed input example and infer or declare a serving signature that includes required contextual fields and output schema. Request minimal catalog/schema and model creation permissions for the release service principal rather than granting workspace admin. ExplanationCorrect Answer A:The action targets the stated cause: Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. Check the repair by: list the model version in the target catalog and verify its source run and access grants. Other Answers B:Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. C:Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. D:Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema.
Question 452 A team logs an MLflow model successfully but cannot find it in the approved Unity Catalog registry because it used an unqualified local registry name. Which underlying technical principle explains why this occurs? Registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval. Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. Managed MCP discovery does not automatically grant rights to governed tables or semantic resources. Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. ExplanationCorrect Answer D:Configure the Unity Catalog registry and register using the intended catalog.schema.model three-level name with appropriate privileges. Other Answers A:That mechanism describes another problem: A production endpoint always loads “latest” from the registry and unexpectedly switches to a new untested model version. It does not explain this case, where logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. B:Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. C:Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema.
Question 453 A team logs an MLflow model successfully but cannot find it in the approved Unity Catalog registry because it used an unqualified local registry name. After correction, what targeted test should demonstrate success? Run the tool with the production principal and inspect both the permission denial before grants and authorized query after. Attempt registration with a scoped principal, verify expected denial before grants and success after least-privilege grants. Publish an unapproved test version and verify production still serves the prior approved artifact. List the model version in the target catalog and verify its source run and access grants. ExplanationCorrect Answer D:Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. Other Answers A:List the model version in the target catalog and verify its source run and access grants. B:List the model version in the target catalog and verify its source run and access grants. C:List the model version in the target catalog and verify its source run and access grants.
Question 454 A team logs an MLflow model successfully but cannot find it in the approved Unity Catalog registry because it used an unqualified local registry name. Which release safeguard most directly addresses this failure class? Maintain contract-based regression tests from signed input/output examples. Manage registry grants through reviewed deployment identities and auditable permission policies. Standardize three-level naming, registry configuration and permission smoke tests in release automation. Maintain principal-to-tool-to-data entitlement maps for each managed MCP integration. ExplanationCorrect Answer C:Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. Other Answers A:That logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. B:Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. D:This control addresses a different exposure: A Databricks-managed Genie MCP tool works in development, but a production custom agent cannot call it because the workspace identity lacks required data grants. It would not prevent this failure, because logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema.
Question 455 A developer can create models in a sandbox schema but fails to register the production model after deployment due to missing UC privileges. Which design change directly satisfies the stated constraints? Configure the Unity Catalog registry and register using the intended catalog.schema.model three-level name with appropriate privileges. Pin deployment to an explicitly approved registered model version or governed alias and promote it only after evaluation. Request minimal catalog/schema and model creation permissions for the release service principal rather than granting workspace admin. Grant the principal the appropriate endpoint query permission after checking workspace policy and remove unrelated broad privileges. ExplanationCorrect Answer C:The action targets the stated cause: Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. Check the repair by: attempt registration with a scoped principal, verify expected denial before grants and success after least-privilege grants. Other Answers A:Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. B:Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. D:Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights.
Question 456 A developer can create models in a sandbox schema but fails to register the production model after deployment due to missing UC privileges. Which causal explanation best accounts for the failure? Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. Discovery or viewing permissions do not necessarily include permission to invoke a Model Serving endpoint. Registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval. Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. ExplanationCorrect Answer D:Request minimal catalog/schema and model creation permissions for the release service principal rather than granting workspace admin. Other Answers A:Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. B:Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. C:That mechanism describes another problem: A production endpoint always loads “latest” from the registry and unexpectedly switches to a new untested model version. It does not explain this case, where unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights.
Question 457 A developer can create models in a sandbox schema but fails to register the production model after deployment due to missing UC privileges. Which concrete acceptance test best demonstrates the proposed change works? Publish an unapproved test version and verify production still serves the prior approved artifact. Attempt registration with a scoped principal, verify expected denial before grants and success after least-privilege grants. List the model version in the target catalog and verify its source run and access grants. Execute an inference as the principal with and without the minimal query grant, confirming expected allow/deny behavior. ExplanationCorrect Answer B:Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. Other Answers A:Attempt registration with a scoped principal, verify expected denial before grants and success after least-privilege grants. C:Attempt registration with a scoped principal, verify expected denial before grants and success after least-privilege grants. D:Attempt registration with a scoped principal, verify expected denial before grants and success after least-privilege grants.
Question 458 A developer can create models in a sandbox schema but fails to register the production model after deployment due to missing UC privileges. Which operational practice should be made a durable requirement? Define endpoint-specific service-principal roles and negative authorization tests in infrastructure-as-code. Standardize three-level naming, registry configuration and permission smoke tests in release automation. Use controlled aliases, promotion audits and rollback tests in registry release practice. Manage registry grants through reviewed deployment identities and auditable permission policies. ExplanationCorrect Answer D:Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. Other Answers A:Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. B:This control addresses a different exposure: A team logs an MLflow model successfully but cannot find it in the approved Unity Catalog registry because it used an unqualified local registry name. It would not prevent this failure, because unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. C:That unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights.
Question 459 A production endpoint always loads “latest” from the registry and unexpectedly switches to a new untested model version. What should the implementation team change first to resolve the described defect? Define environment-specific catalog, model endpoint and index bindings in a reviewed Declarative Automation Bundle deployment. Pin deployment to an explicitly approved registered model version or governed alias and promote it only after evaluation. Request minimal catalog/schema and model creation permissions for the release service principal rather than granting workspace admin. Configure the Unity Catalog registry and register using the intended catalog.schema.model three-level name with appropriate privileges. ExplanationCorrect Answer B:The action targets the stated cause: Registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval. Check the repair by: publish an unapproved test version and verify production still serves the prior approved artifact. Other Answers A:Registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval. C:Registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval. D:Registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval.
Question 460 A production endpoint always loads “latest” from the registry and unexpectedly switches to a new untested model version. Why does the current approach fail under these conditions? Unity Catalog evaluates authorization on its securables; notebook execution alone does not confer model-registration rights. Logging artifacts and registering a governed model version are separate lifecycle operations; UC names include catalog and schema. Registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval. Model signatures describe the inference API contract; omitted required fields create integration failures at deployment. ExplanationCorrect Answer C:Pin deployment to an explicitly approved registered model version or governed alias and promote it only after evaluation. Other Answers A:Registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval. B:That mechanism describes another problem: A team logs an MLflow model successfully but cannot find it in the approved Unity Catalog registry because it used an unqualified local registry name. It does not explain this case, where registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval. D:Registry publication does not imply every new version is safe for serving; implicit latest references bypass release approval.
