You use a Microsoft SQL Server 2012 database that contains two tables named SalesOrderHeader
and SalesOrderDetail. The indexes on the tables are as shown in the exhibit.

You write the following Transact-SQL query:

You discover that the performance of the query is slow. Analysis of the query plan shows table
scans where the estimated rows do not match the actual rows for SalesOrderHeader by using an
unexpected index on SalesOrderDetail. You need to improve the performance of the query. What
should you do?

You develop a Microsoft SQL Server 2012 database that contains a heap named OrdersHistoncal.
You write the following Transact-SQL query:
INSERT INTO OrdersHistorical SELECT * FROM CompletedOrders
You need to optimize transaction logging and locking for the statement. Which table hint should
you use?

You develop a Microsoft SQL Server 2012 database. You need to create and call a stored
procedure that meets the following requirements:
– Accepts a single input parameter for CustomerID.
– Returns a single integer to the calling application.
Which Transact-SQL statement or statements should you use? (Each correct answer presents part
of the solution. Choose all that apply.)

You develop a Microsoft SQL Server 2012 database. You need to create a batch process that
meets the following requirements:
– Returns a result set based on supplied parameters.
– Enables the returned result set to perform a join with a table.
Which object should you use?

You develop a Microsoft SQL Server 2012 database. The database is used by two web applications
that access a table named Products. You want to create an object that will prevent the applications
from accessing the table directly while still providing access to the required data. You need to
ensure that the following requirements are met:
– Future modifications to the table definition will not affect the
applications’ ability to access data.
– The new object can accommodate data retrieval and data modification.
– You need to achieve this goal by using the minimum amount of changes to
theexisting applications.
What should you create for each application?

You administer a Microsoft SQL Server 2012 database that contains a table named OrderDetail.
You discover that the NCI_OrderDetail_CustomerID non-clustered index is fragmented. You need
to reduce fragmentation. You need to achieve this goal without taking the index offline. Which
Transact-SQL batch should you use?

You use a Microsoft SQL Server 2012 database. You want to create a table to store Microsoft Word
documents. You need to ensure that the documents must only be accessible via Transact-SQL
queries. Which Transact-SQL statement should you use?

You are a database developer at an independent software vendor. You create stored procedures
that contain proprietary code. You need to protect the code from being viewed by your customers.
Which stored procedure option should you use?

Your database contains two tables named DomesticSalesOrders and InternationalSalesOrders.
Both tables contain more than 100 million rows. Each table has a Primary Key column named
SalesOrderId. The data in the two tables is distinct from one another. Business users want a report
that includes aggregate information about the total number of global sales and total sales amounts.
You need to ensure that your query executes in the minimum possible time. Which query should
you use?

You create a stored procedure that will update multiple tables within a transaction. You need to
ensure that if the stored procedure raises a run-time error, the entire transaction is terminated and
rolled back. Which Transact-SQL statement should you include at the beginning of the stored
procedure?
