NEW QUESTION 1
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in the series.
Start of repeated scenario
Contoso. Ltd. has a Microsoft SQL Server environment that includes SQL Server Integration Services (SSIS), a data warehouse, and SQL Server Analysis Services (SSAS) Tabular and multi-dimensional models.
The data warehouse stores data related to your company sales, financial transactions and financial budgets. All data for the data warehouse originates from the company's business financial system.
The data warehouse includes the following tables:
70-767 dumps exhibit
The company plans to use Microsoft Azure to store older records from the data warehouse. You must modify the database to enable the Stretch Database capability.
Users report that they are becoming confused about which city table to use for various queries. You plan to create a new schema named Dimension and change the name of the dbo.dia_city table to Dimension.city. Data loss is not permissible, and you must not leave traces of the old table in the data warehouse.
You must implement a partitioning scheme for the fact.Transaction table to move older data to less expensive storage. Each partition will store data for a single calendar year, as shown in the exhibit (Click the Exhibit button.) You must align the partitions.
You must improve performance for queries against the fact.Transaction table. You must implement appropriate indexes and enable the Stretch Database capability.
End of repeated scenario
You need to configure the fact. Transaction table.
Which three Transact-SQL segments should you use to develop the solution? To answer, move the appropriate Transact-SQL segments from the list of Transact-SQL segments to the answer area and arrange them in the correct order.

    NEW QUESTION 3
    Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
    After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
    You have the following line-of-business solutions:
    70-767 dumps exhibit ERP system
    70-767 dumps exhibit Online WebStore
    70-767 dumps exhibit Partner extranet
    One or more Microsoft SQL Server instances support each solution. Each solution has its own product catalog. You have an additional server that hosts SQL Server Integration Services (SSIS) and a data warehouse. You populate the data warehouse with data from each of the line-of-business solutions. The data warehouse does not store primary key values from the individual source tables.
    The database for each solution has a table named Products that stored product information. The Products table in each database uses a separate and unique key for product records. Each table shares a column named ReferenceNr between the databases. This column is used to create queries that involve more than once solution.
    You need to load data from the individual solutions into the data warehouse nightly. The following requirements must be met:
    70-767 dumps exhibit If a change is made to the ReferenceNr column in any of the sources, set the value of IsDisabled to True and create a new row in the Products table.
    70-767 dumps exhibit If a row is deleted in any of the sources, set the value of IsDisabled to True in the data warehouse. Solution: Perform the following actions:
    70-767 dumps exhibit Enable the Change Tracking for the Product table in the source databases.
    70-767 dumps exhibit Query the CHANGETABLE function from the sources for the updated rows.
    70-767 dumps exhibit Set the IsDisabled column to True for the listed rows that have the old ReferenceNr value.
    70-767 dumps exhibit Create a new row in the data warehouse Products table with the new ReferenceNr value.
    Does the solution meet the goal?

    • A. Yes
    • B. No

    Answer: B

    Explanation: We must check for deleted rows, not just updates rows.

    NEW QUESTION 4
    Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
    You have a Microsoft SQL Server data warehouse instance that supports several client applications. The data warehouse includes the following tables: Dimension.SalesTerritory, Dimension.Customer,
    Dimension.Date, Fact.Ticket, and Fact.Order. The Dimension.SalesTerritory and Dimension.Customer tables are frequently updated. The Fact.Order table is optimized for weekly reporting, but the company wants to change it to daily. The Fact.Order table is loaded by using an ETL process. Indexes have been added to the table over time, but the presence of these indexes slows data loading.
    All data in the data warehouse is stored on a shared SAN. All tables are in a database named DB1. You have a second database named DB2 that contains copies of production data for a development environment. The data warehouse has grown and the cost of storage has increased. Data older than one year is accessed infrequently and is considered historical.
    You have the following requirements:
    70-767 dumps exhibit Implement table partitioning to improve the manageability of the data warehouse and to avoid the need to repopulate all transactional data each night. Use a partitioning strategy that is as granular as possible.
    70-767 dumps exhibit Partition the Fact.Order table and retain a total of seven years of data.
    70-767 dumps exhibit Partition the Fact.Ticket table and retain seven years of data. At the end of each month, the partition structure must apply a sliding window strategy to ensure that a new partition is available for the upcoming month, and that the oldest month of data is archived and removed.
    70-767 dumps exhibit Optimize data loading for the Dimension.SalesTerritory, Dimension.Customer, and Dimension.Date tables.
    70-767 dumps exhibitMaximize the performance during the data loading process for the Fact.Order partition.
    70-767 dumps exhibit Ensure that historical data remains online and available for querying.
    70-767 dumps exhibit Reduce ongoing storage costs while maintaining query performance for current data. You are not permitted to make changes to the client applications.
    You need to configure data loading for the tables.
    Which data loading technology should you use for each table? To answer, select the appropriate options in the answer area.
    70-767 dumps exhibit

      Answer:

      Explanation: Scenario: The Dimension.SalesTerritory and Dimension.Customer tables are frequently updated
      Optimize data loading for the Dimension.SalesTerritory, Dimension.Customer, and Dimension.Date tables. Box 1: Change Tracking
      Box 2: Change Tracking Box 3: Temporal Table
      Temporal Tables are generally useful in scenarios that require tracking history of data changes.
      We recommend you to consider Temporal Tables in the following use cases for major productivity benefits.
      * Slowly-Changing Dimensions
      Dimensions in data warehousing typically contain relatively static data about entities such as geographical locations, customers, or products.
