You administer a Microsoft SQL Server 2012 database named Contoso that contains a
single user-defined database role namedBillingUsers.
All objects in Contoso are in the dbo schema.
You need to grant EXECUTE permission for all stored procedures in Contoso to
BillingUsers.
Which Transact-SQL statement should you use?

You have been hired as a Database Consultant by ABC.com to design a SQL Server 2012
database solution.
You are tasked with designing a scale-out and high-availability SQL Server 2012 Online
Transaction Processing (OLTP) database solution that will maintain copies of data across
two server instances.
Your solution must provide scale-out of read operations by distributing the reads from clients
across two SQL Server 2012 nodes. The data in both SQL Server nodes needs to be
indexed.
What should you include in your solution?

You are a database developer of a Microsoft SQL Server 2012 database. You are designing
a table that will store Customer data from different sources. The table will include a column
that contains the CustomerID from the source system and a column that contains the
SourceID. A sample of this data is as shown in the following table.

You need to ensure that the table has no duplicate CustomerID within a SourceID. You also
need to ensure that the data in the table is in the order of SourceID and then CustomerID.
Which Transact- SQL statement should you use?

You administer a Microsoft SQL Server 2012 database named ContosoDb. Tables are
defined as shown in the exhibit. (Click the Exhibit button.)

You need to display rows from the Orders table for the Customers row having the
CustomerId value set to 1 in the following XML format.

Which Transact-SQL query should you use?

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 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. (Click the Exhibit button.)

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 are a database developer for an application hosted on a Microsoft SQL Server 2012
server. The database contains two tables that have the following definitions:

Global customers place orders from several countries. You need to view the country from
which each customer has placed the most orders.
Which Transact-SQL query do you use?

You use Microsoft SQL Server 2012 to develop a database application. You need to create
an object that meets the following requirements:
Takes an input variable
Returns a table of values
Cannot be referenced within a view
Which object should you use?

You administer a SQL Server 2012 server that contains a database named SalesDb.
SalesDb contains a schema named Customers that has a table named Regions. A user
named UserA is a member of a role named Sales. UserA is granted the Select permission
on the Regions table. The Sales role is granted the Select permission on the Customers
schema.
You need to ensure that the following requirements are met:
The Sales role does not have the Select permission on the Customers schema.
UserA has the Select permission on the Regions table.
