                                                                          NEW QUESTION # 25
                                                                          You have two Fabric workspaces named Workspace1 and Workspace2.
                                                                          You have a Fabric deployment pipeline named deployPipeline1 that deploys items from Workspace1 to Workspace2. DeployPipeline1 contains all the items in Workspace1.
                                                                          You recently modified the items in Workspaces1.
                                                                          The workspaces currently contain the items shown in the following table.

                                                                          Items in Workspace1 that have the same name as items in Workspace2 are currently paired.
                                                                          You need to ensure that the items in Workspace1 overwrite the corresponding items in Workspace2. The solution must minimize effort.
                                                                          What should you do?

                                                                          Answer: B

                                                                          Explanation:
                                                                          When running a deployment pipeline in Fabric, if the items in Workspace1 are paired with the corresponding items in Workspace2 (based on the same name), the deployment pipeline will automatically overwrite the existing items in Workspace2 with the modified items from Workspace1. There's no need to delete, rename, or back up items manually unless you need to keep versions. By simply running deployPipeline1, the pipeline will handle overwriting the existing items in Workspace2 based on the pairing, ensuring the latest version of the items is deployed with minimal effort.


                                                                          NEW QUESTION # 26

                                                                          Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

                                                                          Litware, Inc. is a publishing company that has an online bookstore and several retail bookstores worldwide.
                                                                          Litware also manages an online advertising business for the authors it represents.
                                                                          Existing Environment. Fabric Environment
                                                                          Litware has a Fabric workspace named Workspace1. High concurrency is enabled for Workspace1.
                                                                          The company has a data engineering team that uses Python for data processing.
                                                                          Existing Environment. Data Processing
                                                                          The retail bookstores send sales data at the end of each business day, while the online bookstore constantly provides logs and sales data to a central enterprise resource planning (ERP) system.
                                                                          Litware implements a medallion architecture by using the following three layers: bronze, silver, and gold. The sales data is ingested from the ERP system as Parquet files that land in the Files folder in a lakehouse.
                                                                          Notebooks are used to transform the files in a Delta table for the bronze and silver layers. The gold layer is in a warehouse that has V-Order disabled.
                                                                          Litware has image files of book covers in Azure Blob Storage. The files are loaded into the Files folder.

                                                                          In the source system, the sales data refreshes every six hours starting at midnight each day.
                                                                          The sales data is captured in a Dataflow Gen1 dataflow. When the dataflow runs, new and historical data is captured. The dataflow captures the following fields of the source:
                                                                          Sales Date

                                                                          Price
                                                                          Units

                                                                          Fabric Admins
                                                                          Streaming Admins
                                                                          Existing Environment. Performance Issues
                                                                          Business users perform ad-hoc queries against the warehouse. The business users indicate that reports against the warehouse sometimes run for two hours and fail to load as expected. Upon further investigation, the data engineering team receives the following error message when the reports fail to load: "The SQL query failed while running." The data engineering team wants to debug the issue and find queries that cause more than one failure.
                                                                          When the authors have new book releases, there is often an increase in sales activity. This increase slows the data ingestion process.

                                                                          Litware plans to manage Search Engine Optimization (SEO) for the authors. The SEO data will be streamed from a REST API.

                                                                          Process the SEO data in near-real-time (NRT).
                                                                          Make the book reviews available in the lakehouse without making a copy of the data.
                                                                          When a new book cover image arrives in the Files folder, process the image as soon as possible.

                                                                          Use an INNER JOIN.
                                                                          The goal is to include only products that are assigned to a subcategory. An INNER JOIN ensures that only matching records (i.e., products with a valid subcategory) are included.
                                                                          Join between ProductSubCategories and ProductCategories:

                                                                          WHERE Clause

                                                                          Only active products (where IsActive equals 1) should be included in the gold layer. This filters out inactive products.

                                                                          You need to identify in which cell the failure occurred.

                                                                          Reference contains reference data in the following format.
