QUESTION NO:14

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]

What should you do?

A. Add a district column to the dimUser table.

B. Partition the factSales table on the district column.

C. Create a userDistrict table that contains primary key columns from the dimUser and dimDistrict tables.

D. For each district, create a view of the factSales table that includes a WHERE clause for the district.

QUESTION NO:30

DRAG DROP

You are developing a SQL Server Integration Services (SSIS) package that imports data into a data

warehouse. You are developing the part of the SSIS package that populates the ProjectDates

dimension table.

The business key of the ProjectDates table is the ProjectName column. The business user has given

you the dimensional attribute behavior for each of the four columns in the ProjectDates table:

ExpectedStartDate -New values should be tracked over time.

ActualStartDate – New values should not be accepted.

ExpectedEndDate – New values should replace existing values.

ActualEndDate – New values should be tracked over time.

You use the SSIS Slowly Changing Dimension Transformation. You must configure the Change Type

value for each source column. Which settings should you select? (To answer, select the appropriate

setting or settings in the answer area. Each Change Type may be used once, more than once, or not

at all.)

QUESTION NO:9

You are reviewing the design of an existing fact table named factSales, which is loaded from a SQL Azure database by a SQL Server Integration Services (SSIS) package each day. The fact table has approximately 1 billion rows and is dimensioned by product, sales date, and sales time of day.

The database administrator is concerned about the growth of the database. Users report poor reporting performance against this database. Reporting requirements have recently changed and the only remaining report that uses this fact table reports sales by product name, sale month, and sale year. No other reports will be created against this table. You need to reduce the report processing time and minimize the growth of the database. What should you do?

A. Partition the table by product type.

B. Create a view over the fact table to aggregate sales by month.

C. Change the granularity of the fact table to month.

D. Create an indexed view over the fact table to aggregate sales by month.

Answer: C

QUESTION NO:7

DRAG DROP You are editing a SQL Server Integration Services (SSIS) package that contains a task with a sensitive property. You need to create a project parameter and configure it so that its value is encrypted when it is deployed to the SSIS catalog. Which three steps 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.)

Answer:

QUESTION NO:26

You are using SQL Server Data Tools to develop a SQL Server Integration Services (SSIS) project.

A. Convert the package Connection Manager in the first package to a project Connection Manager.

B. Copy the package Connection Manager and paste it into the second package.

C. Convert the project to the Package Deployment model.
