Microsoft TS: Accessing Data with Microsoft .NET Framework 4 Sample Questions:

1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server 2008 database. The database includes a table that
contains information about all the employees.
The database table has a field named EmployeeType that identifies whether an employee is a Contractor or
a Permanent employee.
You declare the Employee entity base type. You create a new Association entity named Contractor that
inherits the Employee base type.
You need to ensure that all Contractors are bound to the Contractor class. What should you do?

A) Use the Entity Data Model Designer to set up an association between the Contractor class and EmployeeType.
B) Use the Entity Data Model Designer to set up a referential constraint between the primary key of the Contractor class and EmployeeType.
C) Modify the .edmx file to include the following line of code: <Condition ColumnName="EmployeeType" Value="Contractor" />
D) Modify the .edmx file to include the following line of code: <NavigationProperty Name="Type" FromRole="EmployeeType" ToRole="Contractor" />

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that
uses the Entity Framework.
The application has an entity model that contains a SalesOrderHeader entity. The entity includes an
OrderDate property of type DateTime.
You need to retrieve the 10 oldest SalesOrderHeaders according to the OrderDate property.
Which code segment should you use?

A) var model = new AdventureWorksEntities(); var sales = model.SalesOrderHeaders.OrderByDescending(soh => soh.OrderDate).Take(10);
B) var model = new AdventureWorksEntities(); var sales = model.SalesOrderHeaders.OrderBy(soh => soh.OrderDate).Take(10);
C) var model = new AdventureWorksEntities(); var sales = model.SalesOrderHeaders.Take(10).OrderBy(soh => soh.OrderDate);
D) var model = new AdventureWorksEntities(); var sales = model.SalesOrderHeaders.Take(10).OrderByDescending(soh => soh.OrderDate);

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.

string
that is used by the application. Which connection string should you add to the app.config file?

model.csdIl
res://MyComparny.Data,Culture=neutral,PublicKeyToken=null/model.ssdIl
res://MyComparny.Data,Culture=neutral,PublicKeyToken=null/model.msl;
provider=System.Data.OleDBClient;
provider connection string='Provider=sqloledb;DataSource=localhost;Initial
Catalog=AdventureWorks;lntegrated Security=SSPI;multipleactivesuitsets=true'"
