NEW QUESTION 3
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
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 FactOrder 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.
• 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.
• Partition the FactOrder table and retain a total of seven years of data.
• 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.
• Optimize data loading for the Dimension.SalesTerritory, Dimension.Customer, and Dimension.Date tables.
• Incrementally load all tables in the database and ensure that all incremental changes are processed.
• Maximize the performance during the data loading process for the Fact.Order partition.
• Ensure "that historical data remains online and available for querying.
• Reduce ongoing storage costs while maintaining query performance for current data. You are not permitted to make changes to the client applications.
End of repeated scenario
You need to optimize data loading for the Dimension.SalesTerritory, Dimension.Customer, and Dimension.Date tables.
Which technology should you use for each table?
To answer, select the appropriate technologies in the answer area.
70-767 dumps exhibit
70-767 dumps exhibit

    Answer:

    Explanation: Box 1: Temporal table Box 2: Temporal table
    Compared to CDC, Temporal tables are more efficient in storing historical data as it ignores insert actions. Box 3: Change Data Capture (CDC)
    By using change data capture, you can track changes that have occurred over time to your table. This kind of functionality is useful for applications, like a data warehouse load process that need to identify changes, so they can correctly apply updates to track historical changes over time.
    CDC is good for maintaining slowly changing dimensions.
    Scenario: Optimize data loading for the Dimension.SalesTerritory, Dimension.Customer, and Dimension.Date tables.
    The Dimension.SalesTerritory and Dimension.Customer tables are frequently updated. References:

    You are developing a Microsoft SQL Server Integration Services (SSIS) projects. The project consists of several packages that load data warehouse tables.
    You need to extend the control flow design for each package to use the following control flow while minimizing development efforts and maintenance:
    70-767 dumps exhibit
    Solution: You add the control flow to a control flow package part. You add an instance of the control flow package part to each data warehouse load package.
    Does the solution meet the goal?

    • A. Yes
    • B. No

    Answer: A

    Explanation: A package consists of a control flow and, optionally, one or more data flows. You create the control flow in a package by using the Control Flow tab in SSIS Designer.

    Answer: AD

    NEW QUESTION 8
    You have a Microsoft SQL Server Integration Services (SSIS) package that loads data into a data warehouse each night from a transactional system. The package also loads data from a set of Comma-Separated Values (CSV) files that are provided by your company’s finance department.
    The SSIS package processes each CSV file in a folder. The package reads the file name for the current file into a variable and uses that value to write a log entry to a database table.
    You need to debug the package and determine the value of the variable before each file is processed.
    Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
    70-767 dumps exhibit

      Answer:

      Explanation: You debug control flows.
      The Foreach Loop container is used for looping through a group of files. Put the breakpoint on it.
      The Locals window displays information about the local expressions in the current scope of the Transact-SQL debugger.

      NEW QUESTION 9
      You have a database named DB1. You create a Microsoft SQL Server Integration Services (SSIS) package that incrementally imports data from a table named Customers. The package uses an OLE DB data source for
      connections to DB1. The package defines the following variables.
      70-767 dumps exhibit
      To support incremental data loading, you create a table by running the following Transact-SQL segment:

        NEW QUESTION 10
        You are developing a Microsoft SQL Server Master Data Services (MDS) solution.
        The model contains an entity named Product. The Product entity has three user-defined attributes named Category, Subcategory, and Price, respectively.
        You need to ensure that combinations of values stored in the Category and Subcategory attributes are unique. What should you do?

        • A. Create an attribute group that consists of the Category and Subcategory attribute
        • B. Publish a business rule for the attribute group.
        • C. Publish a business rule that will be used by the Product entity.
        • D. Create a derived hierarchy based on the Category and Subcategory attribute
        • E. Use the Category attribute as the top level for the hierarchy.
        • F. Set the value of the Attribute Type property for the Category and Subcategory attributes toDomainbased.

        Answer: B

        Explanation: In Master Data Services, business rule actions are the consequence of business rule condition evaluations. If a condition is true, the action is initiated.
        The Validation action "must be unique": The selected attribute must be unique independently or in combination with defined attributes.

        NEW QUESTION 11
        Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
        You are designing a data warehouse and the load process for the data warehouse.
        You have a source system that contains two tables named Table1 and Table2. All the rows in each table have a corresponding row in the other table.
        The primary key for Table1 is named Key1. The primary key for Table2 is named Key2.
        You need to combine both tables into a single table named Table3 in the data warehouse. The solution must ensure that all the nonkey columns in Table1 and Table2 exist in Table3. Which component should you use to load the data to the data warehouse?

        • A. the Slowly Changing Dimension transformation
        • B. the Conditional Split transformation
        • C. the Merge transformation
        • D. the Data Conversion transformation
        • E. an Execute SQL task
        • F. the Aggregate transformation
        • G. the Lookup transformation

        Answer: G

        Explanation: The Lookup transformation performs lookups by joining data in input columns with columns in a reference dataset. You use the lookup to access additional information in a related table that is based on values in common columns.
        You can configure the Lookup transformation in the following ways: Specify joins between the input and the reference dataset.
        Add columns from the reference dataset to the Lookup transformation output. Etc.
