                                                      質問 # 82
                                                      You use Databricks Asset Bundles to manage two jobs and an app.
                                                      You need to deploy the bundle to development and production environments. The solution must meet the following requirements
                                                      * Deploy the app to both environments.
                                                      * Deploy only one job to development.
                                                      * Minimize administrative effort.
                                                      What should you use?

                                                      正解:B

                                                      解説:
                                                      The correct answer is D - a targets node in databricks.yml.
                                                      Databricks Asset Bundles use a single databricks.yml to define all resources (jobs, apps, pipelines) once, and a targets node to define per-environment overrides. Within the development target, you can use the include
                                                      /exclude mechanism or resource-level overrides to deploy only one of the two jobs. The app and the second job are deployed to both environments through the shared resource definition.
                                                      Option B (separate databricks.yml files per environment) works technically but means duplicating the shared resource definitions across files - any change to a shared resource requires edits in multiple places, which is exactly the administrative overhead the question wants to avoid.
                                                      Option A (resources node) defines resources globally across all targets - it doesn't provide environment- specific filtering. Option C (variables node) parameterises values like cluster sizes or paths but doesn't control which resources are deployed to which environment.

                                                      質問 # 83
                                                      Hotspot Question
                                                      You have an Azure Databricks workspace that is enabled for Unity Catalog.
                                                      You need to implement a data lifecycle and expiration solution that meets the following requirements:
                                                      - Transaction logs and deleted data files that are older than 90 days
                                                      must be removed from Delta tables to reclaim storage.
                                                      - All the tables must remain available for querying during the cleanup
                                                      process.
                                                      - Administrative effort must be minimized.
                                                      What should you do for each requirement? To answer, select the appropriate options in the answer area.
                                                      NOTE: Each correct selection is worth one point.

                                                      正解:

                                                      解説:


                                                      質問 # 84
                                                      You have an Azure Databricks workspace that is enabled for Unity Catalog and contains a managed Delta table named Sales. Sales stores transaction data and contains the following columns:
                                                      * transactionjd (string)
                                                      * transaction date (date)
                                                      * amount (decimal)
                                                      You need to implement the following data quality requirements by using table-level data quality enforcement:
                                                      * amount must be greater than 0.
                                                      * transaction id must never be null.
                                                      * Invalid records must be rejected when data is written to the Sales table.
                                                      What should you do?

                                                      正解:D

                                                      解説:
                                                      The correct answer is D - a NOT NULL constraint on transaction_id and a CHECK constraint on amount.
                                                      Delta Lake table constraints are enforced at write time by the Delta engine itself. A NOT NULL constraint rejects any INSERT or UPDATE that would place a null in transaction_id. A CHECK constraint with amount
                                                      > 0 rejects any row where amount is zero or negative. Combined, they implement exactly the stated quality rules: bad rows are rejected when data is written, not filtered away at read time.
                                                      Options A and C (SELECT with WHERE / views) are read-time constructs - they don't prevent invalid data from entering the table. A clever pipeline bypass could write directly to the table and skip the view entirely.
                                                      Option B (row-level security with WHERE conditions) is an access-control feature for restricting which rows users see, not for enforcing data quality on writes. Table constraints are the only mechanism that genuinely blocks bad data at the storage layer.

                                                      質問 # 85
                                                      You have an Azure Databricks workspace that is enabled for Unity Catalog.
                                                      You need to implement a daily batch data process that requires complex and highly customized Python transformations. The solution must minimize additional complexity.
                                                      What should you include in the solution?

                                                      正解:B

                                                      解説:
                                                      A Databricks notebook provides the flexibility required to implement complex, highly customized Python and PySpark transformations. Scheduling that notebook as a Lakeflow Jobs task supplies native daily orchestration, monitoring, retries, and compute management without introducing another service. Azure Data Factory data flows are oriented toward visually designed transformations and would add external orchestration complexity for logic already implemented most naturally in Python. A continuous job is inappropriate because the workload runs once per day rather than continuously. Spark Declarative Pipelines is effective for declarative batch and streaming ETL, but it is less direct when the core requirement emphasizes highly customized procedural Python transformations. A notebook task therefore provides the necessary programming freedom while keeping scheduling and operation inside Azure Databricks.


                                                      質問 # 86
                                                      Note: This section contains one or more sets of questions with the same scenario and problem. Each question presents a unique solution to the problem. You must determine whether the solution meets the stated goals. More than one solution in the set might solve the problem. It is also possible that none of the solutions in the set solve the problem.
                                                      After you answer a question in this section, you will NOT be able to return. As a result, these questions do not appear on the Review Screen.
                                                      You have an Azure Databricks workspace named Workspace1 that contains a lakehouse and is enabled for Unity Catalog.
                                                      You have a connection to a Microsoft SQL Server database named DB1.
                                                      You need to expose the schemas and tables of DB1 to meet the following requirements:
                                                      - The schemas and tables can be queried in Databricks.
                                                      - The schemas and tables appear alongside other Unity Catalog objects.
                                                      - The data is NOT copied into Databricks-managed storage.
                                                      Solution: You create a Lakeflow Connect pipeline and connect it to DB1.
                                                      Does this meet the goal?

                                                      正解:B

                                                      解説:
                                                      Correct:
                                                      * You create a foreign catalog in Catalog Explorer.
                                                      You should create a Foreign Catalog using Lakehouse Federation.
                                                      Data Copying: Lakehouse Federation queries data directly in the source SQL Server without moving or copying it.
                                                      Seamless Integration: The database schemas and tables appear right inside Unity Catalog alongside your other data objects.Real-time Access: It provides immediate access to live SQL Server data.
                                                      Incorrect:
                                                      * You create a Databricks access connector.
                                                      * You create a Lakeflow Connect pipeline and connect it to DB1.
                                                      Data Copying: Lakeflow Connect is an ingestion tool that physically replicates and copies data into Databricks-managed storage (Delta tables).
                                                      Storage Costs: It violates your requirement to keep data out of Databricks storage.
                                                      * You create a new native catalog in Unity Catalog.
                                                      Note:
                                                      To expose the external SQL Server database in Unity Catalog without copying the data, you must use Lakehouse Federation.
                                                      Here are the step-by-step actions you need to take:
                                                      1. Create a Connection
                                                      Create a securable object in Unity Catalog that specifies the path and credentials to access the SQL Server database.
                                                      Go to Catalog Explorer or use SQL.
                                                      Select External Data > Connections.
                                                      Create a connection using the SQL Server connection details (URL, host, port, and database credentials).
                                                      *-> 2. Create a Foreign Catalog
