Question 1:

You are implementing the indexing strategy for a fact table in a data warehouse. The fact table is named Quotes. The table has no indexes and consists of seven columns:

•

[ID]

•

[QuoteDate]

•

[Open]

•

[Close]

•

[High]

•

[Low]

•

[Volume]

Each of the following queries must be able to use a columnstore index:

•

SELECT AVG ([Close]) AS [AverageClose] FROM Quotes WHERE [QuoteDate] BETWEEN \’20100101\’ AND \’20101231\’.

•

SELECT AVG([High] – [Low]) AS [AverageRange] FROM Quotes WHERE [QuoteDate] BETWEEN \’20100101\’ AND \’20101231\’.

•

SELECT SUM([Volume]) AS [SumVolume] FROM Quotes WHERE [QuoteDate] BETWEEN \’20100101\’ AND \’20101231\’.

You need to ensure that the indexing strategy meets the requirements. The strategy must also minimize the number and size of the indexes. What should you do?

A. Create one columnstore index that contains [ID], [Close], [High], [Low], [Volume], and [QuoteDate].

B. Create three coiumnstore indexes: One containing [QuoteDate] and [Close] One containing [QuoteDate], [High], and [Low] One containing [QuoteDate] and [Volume]

C. Create one columnstore index that contains [QuoteDate], [Close], [High], [Low], and [Volume].

D. Create two columnstore indexes: One containing [ID], [QuoteDate], [Volume], and [Close] One containing [ID], [QuoteDate], [High], and [Low]

Correct Answer: C

You are completing the installation of the Data Quality Server component of SQL Server Data Quality Services (DQS).

You need to complete the post-installation configuration.

What should you do?

A. Run the DQSInstaller.exe command.

B. Install the data providers that are used for data refresh.

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 SQL Azure. 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. Audit

B. Source Assistant

C. Script Task

D. Conditional Split

Correct Answer: D

Question 4:

You are reviewing the design of a student dimension table in an existing data warehouse hosted on SQL Azure.

The current dimension design does not allow the retention of historical changes to student attributes such as ParentOccupation.

You need to redesign the dimension to enable the full historical reporting of changes to multiple student attributes including ParentOccupation.

What should you do?

A. Add CurrentValue and PreviousValue columns to the student dimension.

B. Enable Snapshot Isolation on the data warehouse.

C. Add an IsCurrent column to the student dimension.

D. Add StartDate and EndDate columns to the student dimension.

Correct Answer: D

Explanation: Adding a start and end date will give you this ability as when a record is inserted and given a start and end date, you\’ll have the ability to determine when they were active therefore giving you a retention of historical changes

Question 5:

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 6:

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 a database administrator for an e-commerce company that runs an online store. The company has the databases described in the following table.

Product prices are updated and are stored in a table named Products on DB1. The Products table is deleted and refreshed each night from MDS by using a Microsoft SQL Server Integration Services (SSIS) package. None of the data sources

are sorted.

You need to update the SSIS package to add current prices to the Products table.

What should you use?

A. Lookup transformation

B. Merge transformation

C. Merge Join transformation

D. MERGE statement

E. Union All transformation

F. Balanced Data Distributor transformation

G. Sequential container

H. Foreach Loop container

Correct Answer: D

In the current release of SQL Server Integration Services, the SQL statement in an Execute SQL task can contain a MERGE statement. This MERGE statement enables you to accomplish multiple INSERT, UPDATE, and DELETE operations in a single statement.

Question 7:

You plan to use the dtutil.exe utility with Microsoft SQL Server Integration Services (SSIS) to customize packages. You 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

C. dtutil.exe /SQL package1 /COPY OTS;c:\repository\package1.dtsx

D. dtutil.exe /SQL package1 /DELETE

Correct Answer: A

Question 8:

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.

Your company uses Microsoft SQL Server to deploy a data warehouse to an environment that has a SQL Server Analysis Services (SSAS) instance. The data warehouse includes the Fact.Order table as shown in the following table definition. The table has no indexes.

You must minimize the amount of space that indexes for the Fact.Order table consume. You run the following queries frequently. Both queries must be able to use a columnstore index:

You need to ensure that the queries complete as quickly as possible.

Solution: You create one columnstore index that includes the [Order Date Key], [Tax Amount], and [Total Excluding Tax] columns.

Does the solution meet the goal?

A. Yes

B. No

Correct Answer: A

You should use a columnstore index.

Columnstore indexes are the standard for storing and querying large data warehousing fact tables. This index uses column-based data storage and query processing to achieve gains up to 10 times the query performance in your data

warehouse over traditional row-oriented storage.

Question 9:

A SQL Server Integration Services (SSIS) package named DataFeed interacts with an external vendor data feed. The package is executed several times a day, either as part of other packages\’ control flow or by itself. The external data feed

is unreliable because network failures and slow response times are frequent. The package is currently deployed on the file system.

To analyze the reliability of the external data feed, you must collect execution data.

Every time the DataFeed package is executed, the following information must be logged:

Start Time

End Time

Execution Result

Execution Duration

You need to design a logging solution that meets the requirements by using the least amount of administrative and development effort.

Correct Answer:

Question 10:

A SQL Server Integration Services (SSIS) project has been deployed to the SSIS catalog. The project includes a project Connection Manager to connect to the data warehouse. The SSIS catalog includes two Environments:

Test

Production

Each Environment defines a single Environment Variable named ConnectionString of type string. The value of each variable consists of the connection string to the test or production data warehouses.

You need to execute deployed packages by using either of the defined Environments.

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.)
