D. Change the isolation level of each query.
Answer: A
QUESTION 113
You are a database developer.
You plan to design a database solution by using SQL Server 2008.
You are writing a query that returns XML data from a table in a database.
You need to ensure that your result set is encapsulated within a root element.
What should you do?
A. Use the RAW mode along with an ELEMENTS directive.
B. Use the PATH mode along with a ROOT directive.
C. Use the EXPLICIT mode along with a TYPE directive.
D. Use the AUTO mode along with a ROOT directive.

QUESTION 114
You use SQL Server 2008 to design a database that will hold incoming XML responses for an Electronic Data Interchange system.
You have the following requirements:
– The database is scalable.
– The data is accessible to heterogeneous platforms.
– The database stores various types of reports from multiple sources.
– The database stores large amounts of data.
– The solution allows search by keywords.
– Full text search is not enabled in the database.
You need to design the database to meet these requirements.
What should you do?
A. Use SQL Server 2008 tables to store the data in a varchar (max) column.
B. Use SQL Server 2008 tables to store the data in a varbinary (max) column with FILESTREAM
option.
C. Use SQL Server 2008 tables to store the data in a varbinar y(max) column.
D. Use SQL Server 2008 tables to store the data using XML datatype.
Answer: D
QUESTION 115
You need to develop a stored procedure strategy that will manipulate temporary result sets to meet the following requirements:
– Stored procedures must receive result sets as parameters
– The strategy must be developed by using the minimum amount of effort
– The result sets will contain less than 1,000 rows.
What should you use?
A. a common table expression (CTE)
B. a view
C. a user-defined table type
D. a scalar function
Answer: C
QUESTION 116
You are a database developer.
You plan to design a database solution by using SQL Server 2008.
The database will contain a view.
The view will contain a computed column that will be indexed.
The computed column will use a user-defined scalar function.
The function will perform complex string manipulations.
You need to identify the appropriate function to use.
What should you do?
A. Use a nondeterministic Transact-SQL table-valued function.
B. Use a deterministic Transact-SQL table-valued function.
C. Use a nondeterministic common language runtime (CLR) scalar-valued function.
D. Use a deterministic common language runtime (CLR) scalar-valued function.
Answer: D
QUESTION 117

B. Parse input parameters to prevent the use of the following strings:
;
—
/*
*/
C. Parse input parameters to prevent the use of the following strings:
&
@

QUESTION 118
You are a database developer.
You plan to design a database solution by using SQL Server 2008.
Your company operates a fulfillment warehouse.
The company has the following business requirements:
– The packing of items to fulfill orders is processed as quickly as possible.
– When the product picker indicates that a box is full, the exact items list of the content and invoice are made available.
You plan to design a Transact-SQL user-defined function.
The function must perform the following tasks:
– Accept a list of value pairs named ProductID and Quantity as input.
– Retrieve the product price information from the ProductPrice table.
– Calculate the total price for each product.
– Calculate the total price for all products.
– Return the detailed and aggregated totals.
You need to design the function to meet these requirements.
You want to achieve this goal by using the minimum amount of coding effort.
What should you do?
A. Create a multistatement table-valued function that accepts an XML parameter.
B. Create a multistatement table-valued function that accepts a table-valued parameter.
C. Create an inline table-valued function that accepts an XML parameter.
D. Create an inline table-valued function that accepts a table-valued parameter.
Answer: B
QUESTION 119
You have a table that contains a string column.
Most of the rows have the same value.
You need to create a multistep stored procedure that meets the following requirements:
– Accepts a text input parameter
– Provides optimal performance for all input values
– Has only one step using the input parameter as a predicate
What should you use?
