You are creating a Data Quality Services (DQS) solution. You must provide statistics on the accuracy of the data.
You need to use DQS profiling to obtain the required statistics.
Which DQS activity should you use?

• A.Knowledge Discovery
• B.Matching
• C.Matching Policy
• D.Cleansing

Note: This question is part of a series of questions that use the same set of answer choices. An answer choice may be correct for more than one question in the series.
You administer a SQL 2012 server that contains a database named SalesDb. SalesDb contains a schema named Customers that has a table named Regions. A user named userA is a member of a role named Sales.
UserA is granted the Select permission on the Regions table. The Sales role is granted the Select permission on the Customers schema.
You need to remove the Select permission for userA on the Regions table. You also need to ensure that UserA can still access all the tables in the Customers schema, including the Regions table, through the Sales role permissions.
Which Transact-SQL statement should you use?

• A.REVOKE SELECT ON Schema::Customers FROM UserA
• B.REVOKE SELECT ON Schema: Customers FROM Soles
• C.DENY SELECT ON Object::Regions FROM Sales
• D.REVOKE SELECT ON Object::Regions FROM UserA
• E.DENY SELECT ON Schema: Customers FROM UserA
• F.DENY SELECT ON Schema:: Customers FROM Soles
• G.EXEC sp_oddrolemember 'Sales', 'UserA'
• H.EXEC 3p_droprolemember 'Sales', 'UserA'
• I.REVOKE SELECT ON Object::Regions FROM Soles
• J.DENY SELECT ON Object::Regions FROM UserA

You are developing a SQL Server Integration Services (SSIS) package to load data into a data warehouse. The package consists of several data flow tasks.
The package experiences intermittent errors in the data flow tasks.
If any data flow task fails, all package error information must be captured and written to a SQL Server table by using an OLE DB connection manager.
You need to ensure that the package error information is captured and written to the table.
What should you do?

• A.Store the System::ExecutionInstanceGUID variable in the custom log table.
• B.View the All Messages subsection of the All Executions report for the package.
• C.Use an event handler for OnTaskFailed for the package.
• D.Enable the SSIS log provider for SQL Server for OnError in the package control flow.
• E.Store the System::SourceID variable in the custom log table.
• F.Deploy the project by using dtutil.exe with the /COPY DTS option.
• G.Deploy the project by using dtutil.exe with the /COPY SQL option.
• H.Create a SQL Server Agent job to execute the SSISDB.catalog.validate_package stored procedure.
• I.Create a table to store error information. Create an error output on each data flow destination that writes OnTaskFailed event text to the table.
• J.Create a SQL Server Agent job to execute the SSISDB.catalog.validate_project stored procedure.
• K.View the job history for the SQL Server Agent job.
• L.Deploy the .ispac file by using the Integration Services Deployment Wizard.
• M.Enable the SSIS log provider for SQL Server for OnTaskFailed in the package control flow.
• N.Create a table to store error information. Create an error output on each data flow destination that writes OnError event text to the table.
• O.Use an event handler for OnError for the package.
• P.Create a SQL Server Agent job to execute the SSISDB.catalog.create_execution and SSISDB.catalog.*tart_execution stored procedures.
• Q.Use an event handler for OnError for each data flow task.
• R.Store the System::ServerExecutionID variable in the custom log table.

DRAG DROP
You administer several Microsoft SQL Server 2012 servers. Your company has a number
of offices across the world connected by using a wide area network (WAN).
Connections between offices vary significantly in both bandwidth and reliability.
You need to identify the correct replication method for each scenario.
What should you do? (To answer, drag the appropriate replication method or methods to the correct location or locations in the answer area. Each replication method may be used once, more than once, or not at all.)

Correct Answer:

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.Merge Join
• B.DQS Cleansing
• C.Pivot
• D.CDC Splitter
