QUESTION 222
You are designing a data warehouse that uses SQL Server 2012.
The data warehouse contains a table named factSales that stores product sales. The table has a clustered index on the primary key, four foreign keys to dimension tables, and an aggregate column for sales totals. All key columns use the int data type and the aggregate column uses the money data type.
You need to increase the speed of data retrieval from the factSales table.
Which index type should you add to the table?

A.    Clustered
B.    Semantic search
C.    Nonclustered
D.    XML

Answer: C

QUESTION 223
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.
C.    Implement package connection managers.
D.    Implement parent package variables in all packages.

Answer: B

QUESTION 224
You are performance tuning a SQL Server Integration Services (SSIS) package to load sales data from a source system into a data warehouse that is hosted on Windows Azure SQL Database.
The package contains a data flow task that has seven source-to-destination execution trees.
Only three of the source-to-destination execution trees are running in parallel.
You need to ensure that all the execution trees run in parallel.
What should you do?

A.    Set the EngineThreads property of the data flow task to 7.
B.    Set the MaxConcurrentExcecutables property of the package to 7.
C.    Create seven data flow tasks that contain one source-to-destination execution tree each.
D.    Place the data flow task in a For Loop container that is configured to execute seven times.

Answer: A

QUESTION 225
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.    DQS Cleansing
B.    Merge Join
C.    Pivot
D.    Conditional Split

Answer: D

QUESTION 226
You are designing a data warehouse that uses SQL Server 2012.

You need to run an update statement against the table.
What should you do first?

A.    Pause the columnstore index.
B.    Change the recovery model of the database to Bulk-logged.
C.    Change the non-clustered columnstore index to be a clustered columnstore index.

Answer: D

QUESTION 227
Reporting from a Star schema is simpler than reporting from a normalized online transactional processing (OLTP) schema.
What are the reasons for wanting simpler reporting? (Choose all that apply.)

A.    A Star schema typically has fewer tables than a normalized schema. Therefore, queries are simpler because they require fewer joins.
B.    A Star schema has better support for numeric data types than a normalized relational schema; therefore, it is easier to create aggregates.
C.    There are specific Transact-SQL expressions that deal with Star schemas.
D.    A Star schema is standardized and narrative; you can find the information you need for a report quickly.

Answer: AD

QUESTION 228
If you want to switch content from a nonpartitioned table to a partition of a partitioned table, what conditions must the nonpartitioned table meet? (Choose all that apply.)

A.    It must have the same constraints as the partitioned table.
B.    It must have the same compression as the partitioned table.
C.    It must be in a special PartitionedTables schema.
D.    It must have a check constraint on the partitioning column that guarantees that all of the data goes to exactly one partition of the partitioned table.
E.    It must have the same indexes as the partitioned table.

Answer: ABDE
