Q21. You are creating a SQL Server Integration Services (SSIS) package that implements a Type 3 Slowly Changing Dimension (SCD).
You need to add a task or component to the package that allows you to implement the SCD logic.
What should you use?
A. a Data Conversion component
B. an Execute SQL task that executes a MERGE statement on the database
C. a Merge component
D. an Expression task
Answer: C
Explanation: Note: Type of Slowly Changing Dimensions Slowly Changing Dimensions are categorized into three types named: Type 1, Type 2, and Type3. The Type 1 SCD does not maintain the history of changing attributes, it overwrites values of the attributes. Type 2 maintains historical values for changing attributes. Type 3 that we do not use much maintains separate columns for changed attributes. SSIS SCD wizard supports both Type 1 and Type 2. Using MERGE instead of SCD wizard Replacement of SCD wizard with MERGE is not a straightforward technique. If the SCD has both Type 1 and Type 2 types attributes, they need to be handled separately.
Q22. You are the administrator of a server that hosts Data Quality Server for a large retail company.
The server had a hardware failure during business hours.
You need to restore the server that hosts Data Quality Server to another server. You have a recent backup of all the required databases.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)
A. Restore the DQS_MAIN, DQS_PROJECTS, and DQS_STAGING_DATA databases to another server as soon as possible.
B. Execute the DQS_MAIN.internal_core.RestoreDQDatabases stored procedure with the appropriate parameter.
C. Restore only the DQS_MAIN and DQS_STAGING_DATA databases to another server as soon as possible.
D. Execute the DQS_MAIN.internal_core.InitServer stored procedure with the appropriate parameter.
Answer: B,D
Explanation: Steps to restore DQS Databases:
Restore DQS_MAIN database.
Restore the DQS_PROJECTS database.
Restore the DQS_STAGING_DATA database.
In Object Explorer, right-click the server, and then click.New Query.
In the Query Editor window, copy the following SQL statements, and
replace.<PASSWORD>.with the password that you provided during the DQS
installation for the database master key:
USE [DQS_MAIN]
GO
EXECUTE [internal_core].[RestoreDQDatabases] '<PASSWORD>'
GO
.Press F5 to execute the statements. Check the.Results.pane to verify that the statements have executed successfully.
Note:
* Backup and restore of SQL Server databases are common operations that database administrators perform for preventing loss of data in a case of disaster by recovering data from the backup databases. Data Quality Server is primarily implemented by two SQL Server databases: DQS_MAIN and DQS_PROJECTS. The backup and restore procedures of the Data Quality Services (DQS) databases are similar to any other SQL Server databases.
Q23. You are the Master Data Services (MDS) administrator at your company.
An existing user needs to integrate data from other systems into MDS.
You need to give the user permissions to integrate data.
Which user management menu item should you select? (To answer, configure the
appropriate option or options in the dialog box in the answer area.)
Answer:
Q24. You are developing a SQL Server Integration Services (SSIS) package that imports data into a data warehouse hosted on SQL Azure.
The package uses a Foreach container to process text files found in a folder. The package must be deployed to a single server by using the Project Deployment model.
Multiple SQL Server Agent jobs call the package. Each job is executed on a different schedule.
Each job passes a different folder path to the package.
You need to configure the package to accept the folder path from each job.
Which package configuration should you use?
A. Parent Package Variable
B. XML Configuration File
C. Environment Variable
D. .dtsConfig file
E. Registry Entry
Answer: C
Q25. You are installing SQL Server Data Quality Services (DQS).
You need to give users belonging to a specific Active Directory group access to the Data Quality Server.
Which SQL Server application should you use?
A. Data Quality Client with administrative credentials
B. SQL Server Configuration Manager with local administrative credentials
C. SQL Server Data Tools with local administrative permissions
D. SQL Server Management Studio with administrative credentials
Answer: D

Q26. You are designing a package control flow. The package moves sales order data from a SQL Azure transactional database to an on-premise reporting database. The package will run several times a day, while new sales orders are being added to the transactional database. The current design of the package control flow is shown in the answer area. (Click the Exhibit button.)
The Insert New Orders Data Flow task must meet the following requirements:
Usage of the tempdb database should not be impacted.
Concurrency should be maximized, while only reading committed transactions.
If the task fails, only that task needs to be rolled back.
You need to configure the Insert New Orders Data Flow task to meet the requirements.
How should you configure the transaction properties? (To answer, select the appropriate setting or settings in the answer area.)

Answer:
Q27. Topic 2)
You are the administrator for a Data Quality Server. You are adding a user who must have permission to:
Edit and execute a project
View the activity monitoring data
This user must not be able to:
Perform any kind of knowledge management
Create or change a knowledge base
Terminate an activity or perform administrative duties
You need to develop a Transact-SQL (T-SQL) script to meet these requirements.
What should you do? (To answer, drag the appropriate code segment or segments to the correct location or locations in the answer area.)
Answer:
Q28. A SQL Server Integration Services (SSIS) 2012 package currently downloads sales data from a Windows Azure SQL Database database.
To improve sales data accuracy, exchange rates must be downloaded daily from a public HTTP website instead of from a weekly flat file. The public website hosts a comma-
separated values (CSV) file that contains one row per currency.
You need to download the CSV file to the environment.
What should you use to retrieve the document from the website?
A. a Script component
B. a Web Service task
C. a Web Service source
D. a Script task
Answer: D
Q29. You are designing a SQL Server Integration Services (SSIS) package. The package moves order-related data to a staging table named Order. Every night the staging data is truncated and then all the recent orders from the online store database are inserted into the staging table.
Your package must meet the following requirements:
. If the truncate operation fails, the package execution must stop and report an error. . If the Data Flow task that moves the data to the staging table fails, the entire refresh operation must be rolled back. . For auditing purposes, a log entry must be entered in a SQL log table after each execution of the Data Flow task.
The TransactionOption property for the package is set to Required.
You need to design the package to meet the requirements.
How should you design the control flow for the package? (To answer, drag the appropriate setting from the list of settings to the correct location or locations in the answer area.)
Answer:
Q30. You are developing a SQL Server Integration Services (SSIS) package to implement an incremental data load strategy. The package reads data from a source system that uses the SQL Server change data capture (CDC) feature.
You have added a CDC Source component to the data flow to read changed data from the source system.
You need to add a data flow transformation to redirect rows for separate processing of insert, update, and delete operations.
Which data flow transformation should you use?
A. Audit
B. Merge Join
C. Merge
D. CDC Splitter
Answer: C
Explanation: MERGE with Incremental Loads The change data capture functionality that is new in SQL Server 2008 makes it easier to perform incremental loads reliably to a data warehouse. As an alternative to using parameterized OLE DB Command transformations to perform the inserts and the updates, you can use the MERGE statement to combine both operations.
