You need to use DQS profiling to obtain the required statistics.
Which DQS activity should you use?
A. Cleansing
B. Knowledge Discovery
C. SQL Profiler

need to create a new package ID for package1 on Server1. Which dtutil.exe command should you run?
A. dtutil.exe /FILE c:\repository\packagel.dtsx /DestServer Server! /COPY SQL;package1.dtsx
B. dtutil.exe /I /FILE c:\repository\packagel.dtsx
C. dtutil.exe /SQL package1 /COPY OTS;c:\repository\package1.dtsx

QUESTION 3
You are designing a SQL Server Integration Services (SSIS) data flow to load sales transactions from a source system
into a data warehouse hosted on Windows Azure SQL Database. One of the columns in the data source is named
ProductCode.
Some of the data to be loaded will reference products that need special processing logic in the data flow.
You need to enable separate processing streams for a subset of rows based on the source product code.
Which Data Flow transformation should you use?
A. Multicast
B. Conditional Split
C. Destination Assistant
D. Script Task
Correct Answer: B
Explanation: We use Conditional Split to split the source data into separate processing streams.
A Script Component (Script Component is the answer to another version of this question) could be used but this is not
the same as a Script Task.
QUESTION 4
You are implementing a Microsoft SQL Server data warehouse with a multi-dimensional data model.
Orders are stored in a table named Factorder. The addresses that are associated with all orders are stored in a fact
table named FactAddress. A key in the FoctAddress table specifies the type of address for an order.
You need to ensure that business users can examine the address data by either of the following:
shipping address and billing address
shipping address or billing address type Which data model should you use?
A.
star schema
B.
snowflake schema
C.
conformed dimension
D.
slowly changing dimension (SCD)

fact table
F.
semi-additive measure

non-additive measure
H.
dimension table reference relationship
Correct Answer: H
QUESTION 5
You administer a Microsoft SQL Server 2016 database. The database contains a table named Employee. Part of the
Employee table is shown in the exhibit. (Click the Exhibit button.)
Confidential information about the employees is stored in a separate table named EmployeeData. One record exists
within EmployeeData for each record in the Employee table. You need to assign the appropriate constraints and table
properties to ensure data integrity and visibility. On which column in the Employee table should you use an identity
specification to include a seed of 1,000 and an increment of 1?
A. DateHired
B. DepartmentID
C. EmployeeID
D. EmployeeNum
E. FirstName
F. JobTitle
G. LastName
H. MiddleName
I. ReportsToID
Correct Answer: C
QUESTION 6
You are creating a SQL Server Integration Services (SSIS) package to populate a fact table from a source table. The
fact table and source table are located in a SQL Azure database. The source table has a price field and a tax field. The
OLE
DB source uses the data access mode of Table.
You have the following requirements:
The fact table must populate a column named TotalCost that computes the sum of the price and tax columns.
Before the sum is calculated, any records that have a price of zero must be discarded.
You need to create the SSIS package in SQL Server Data Tools.
In what sequence should you order four of the listed components for the data flow task? (To answer, move the
appropriate components from the list of components to the answer area and arrange them in the correct order.)
Select and Place:
Correct Answer:
QUESTION 7
You are using the Knowledge Discovery feature of the Data Quality Services (DQS) client application to modify an
existing knowledge base.
In the mapping configuration, two of the three columns are mapped to existing domains in the knowledge base. The
third column, named Group, does not yet have a domain.
You need to complete the mapping of the Group column.
What should you do?
A. Map a composite domain to the source column.
B. Create a composite domain that includes the Group column.
C. Add a domain for the Group column.
D. Add a column mapping for the Group column.
Correct Answer: C
QUESTION 8
You are designing a complex SQL Server Integration Services (SSIS) project that uses the Project Deployment model.
The project will contain between 15 and 20 packages. All the packages must connect to the same data source and
destination.
You need to define and reuse the connection managers in all the packages by using the least development effort.
What should you do?
A. Copy and paste the connection manager details into each package.
B. Implement project connection managers.

QUESTION 9
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 section, you will NOT be able to return to it. As a result, these questions will not
appear in the review screen.
You plan to deploy a Microsoft SQL server that will host a data warehouse named DB1.
The server will contain four SATA drives configured as a RAID 10 array.
You need to minimize write contention on the transaction log when data is being loaded to the database.
Solution: You replace the SATA disks with SSD disks.
Does this meet the goal?
A. Yes
B. No
Correct Answer: B
A data warehouse is too big to store on an SSD.
Instead you should place the log file on a separate drive.

SQL Azure database.
The company\\’s auditing policies have the following requirements:
Correct Answer: C
Reference: http://msdn.microsoft.com/en-us/library/ms140223.aspx
QUESTION 11
You are developing a SQL Server Integration Services (SSIS) package.
The package sources data from an HTML web page that lists product stock levels.
You need to implement a data flow task that reads the product stock levels from the HTML web page.
Which data flow sources should you use? Select Two
A. Raw File source
B. XML source
C. Custom source component
D. Flat File source
E. script component
Correct Answer: CE
QUESTION 12
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 have a database named DB1.
You need to track auditing data for four tables in DB1 by using change data capture.
Which stored procedure should you execute first?
A. catalog.deploy_project
B. catalog.restore_project
C. catalog.stop_operation
D. sys.sp_cdc_add_job
E. sys.sp_cdc_change_job
F. sys.sp_cdc_disable_db
Correct Answer: D
Because the cleanup and capture jobs are created by default, the sys.sp_cdc_add_job stored procedure is necessary
only when a job has been explicitly dropped and must be recreated.
Note: sys.sp_cdc_add_job creates a change data capture cleanup or capture job in the current database. A cleanup job
is created using the default values when the first table in the database is enabled for change data capture. A capture
job
is created using the default values when the first table in the database is enabled for change data capture and no
transactional publications exist for the database. When a transactional publication exists, the transactional log reader is
used to
drive the capture mechanism, and a separate capture job is neither required nor allowed.
Note: sys.sp_cdc_change_job

QUESTION 13
You are designing a data warehouse hosted on Windows Azure SQL Database. The data warehouse currently includes
the dimUser and dimRegion dimension tables and the factSales fact table. The dimUser table contains records for each
user permitted to run reports against the warehouse, and the dimRegion table contains information about sales regions.
The system is accessed by users from certain regions, as well as by area supervisors and users from the corporate
headquarters.
You need to design a table structure to ensure that certain users can see sales data for only certain regions. Some
users must be permitted to see sales data from multiple regions.
What should you do?
A. For each region, create a view of the factSales table that includes a WHERE clause for the region.
B. Create a userRegion table that contains primary key columns from the dimUser and dimRegion tables.
C. Add a region column to the dimUser table.
D. Partition the factSales table on the region column.
Correct Answer: B
