問題3
Note: This question is part of a series of questions that present 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 scenarios is exactly the same in each question in this series.
You are developing a Master Data Management (MDM) solution for a company by using Microsoft SQL Server Integration Services (SSIS), SQL Server Master Data Services (MDS), and SQL Server Data Quality Services (DQS).
You have an MDS model named Geography that contains the entities described in the following table.

You define a domain-based attribute in the State entity that references the CountryRegion entity. You define another domain-based attribute in the city entity that references the State and CountryRegion entities. A single derived hierarchy named Geography supports navigation between the CountryRegion, State, and City levels.
Subscription views exist for all entities. The subscription views have the same name as the entity on which they are based.
You initialize each entity member. New City entity members are imported daily based on customer city values in a Customer Relationship Management (CRM) database. The CRM database is a SQL Server relational database. When new cities are imported from the CRM database, the state codes must be standardized to those already defined in the State entity.
In the CRM database, sales managers and assigned to countries/regions. A sales manager may be assigned to one or more countries/regions. A country/region may have one or more assigned sales managers. The CRM database contains a table named ManagerCountryRegion that stores a row for each manager-country/region relationship.
You create the following MDS users and map each user to an Active Directory Domain Services (AD DS) user account: User1, User2, and User3. Both User1 and User2 belong to the Explorer functional area.
Users must be able to complete the tasks described in the following table.

You need to perform the initial data loading process of the DQS knowledge base, based on the CountryRegion Entity in the MDS model.
Which three 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.

問題5
Your company manufactures several types of products.
The company has a production tracking application that stores the following data about the products:
The production date
The cost of production
The names of the products
The amount of waste created
The number of products produced
The name of the facility where the products are produced
You are designing a data warehouse for the data. You add a Date dimension.
You need to ensure that you can create a composite primary key for the fact table.
Which two columns should you add to the new dimension tables? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

正確答案: C,D
問題6
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.

To support incremental data loading, you create a table by running the following Transact-SQL segment:

You need to create a DML statements that updates the LastKeyByTable table.
How should you complete the Transact-SQL statement? To answer, select the appropriate Transact-SQL segments in the dialog box in the answer area.
正確答案:

問題7
You are testing a Microsoft SQL Server Integration Services (SSIS) package. The package includes the Control Flow task shown in the Control Flow exhibit (Click the Exhibit button) and the Data Flow task shown in the Data Flow exhibit. (Click the Exhibit button.)


You declare a variable named Seed as shown in the Variables exhibit. (Click the Exhibit button.) The variable is changed by the Script task during execution.

You need to be able to interrogate the value of the Seed variable after the Script task completes execution.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.

問題8
You are designing an indexing strategy for a data warehouse. The data warehouse contains a table named Table1. Data is bulk inserted into Table1.
You plan to create the indexes configured as shown in the following table.

Which type of index should you use to minimize the query times of each index? To answer, drag the appropriate index types to the correct indexes. Each index type may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
正確答案:

問題9
You are developing a Microsoft SQL Server Integration Services (SSIS) package to incrementally load new and changed records from a data source.
The SSIS package must load new records into Table1 and updated records into Table1_Updates. After loading records, the package must call a Transact-SQL statement to process updated rows according to existing business logic.
You need to complete the design of the SSIS package.
Which tasks should you use? To answer, drag the appropriate SSIS objects to the correct targets. Each SSIS object may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
正確答案:

Explanation

Step 1: CDC Control Task Get Processing Range
Step 2: Mark Processed Range
Step 3: Data Flow
The Data Flow task encapsulates the data flow engine that moves data between sources and destinations, and lets the user transform, clean, and modify data as it is moved. Addition of a Data Flow task to a package control flow makes it possible for the package to extract, transform, and load data.
Step 4: CDC Source
The CDC source reads a range of change data from SQL Server 2017 change tables and delivers the changes downstream to other SSIS component.
Step 5: CDC Splitter
The CDC splitter splits a single flow of change rows from a CDC source data flow into different data flows for Insert, Update and Delete operations.
