You use Microsoft SQL Server 2012 to develop a database application.
You need to implement a computed column that references a lookup table by using an INNER JOIN
against another table.
What should you do?

You administer a Microsoft SQL Server 2012 database named ContosoDb. The database contains a
table named Suppliers and a column named IsActive in the Purchases schema. You create a new user
named ContosoUser in ContosoDb. ContosoUser has no permissions to the Suppliers table. You need
to ensure that ContosoUser can delete rows that are not active from Suppliers. You also need to
grant ContosoUser only the minimum required permissions. Which Transact-SQL statement should
you use?

You administer a Microsoft SQL Server 2012 server. You plan to deploy new features to an
application. You need to evaluate existing and potential clustered and non-clustered indexes that
will improve performance.
What should you do?

You administer a Microsoft SQL Server database named Sales. The database is 3 terabytes in size.
The Sales database is configured as shown in the following table.

You discover that Sales_2.ndf is corrupt. You need to recover the corrupted data in the minimum
amount of time. What should you do?

Your database contains a table named SalesOrders. The table includes a DATETIME column named
OrderTime that stores the date and time each order is placed. There is a non-clustered index on the
OrderTime column.
The business team wants a report that displays the total number of orders placed on the current
day.
You need to write a query that will return the correct results in the most efficient manner.
Which Transact-SQL query should you use?

Your application contains a stored procedure for each country. Each stored procedure accepts an
employee identification number through the @EmpID parameter.
You plan to build a single process for each employee that will execute the stored procedure based
on the country of residence.
Which approach should you use?

You use Microsoft SQL Server 2012 to develop a database application.
You create a stored procedure named dbo.ModifyData that can modify rows.
You need to ensure that when the transaction fails, dbo.ModifyData meets the following
requirements:
Does not return an error
Closes all opened transactions
Which Transact-SQL statement should you use?

You are developing a database application by using Microsoft SQL Server 2012.
An application that uses a database begins to run slowly.
You discover that during reads, the transaction experiences blocking from concurrent updates.
You need to ensure that throughout the transaction the data maintains the original version.
What should you do?

You are developing a database application by using Microsoft SQL Server 2012.
You have a query that runs slower than expected.
You need to capture execution plans that will include detailed information on missing indexes
recommended by the query optimizer.
What should you do?

You are developing a database application by using Microsoft SQL Server 2012.
An application that uses a database begins to run slowly.
You discover that a large amount of memory is consumed by single-use dynamic queries.
You need to reduce procedure cache usage from these statements without creating any additional
indexes.
