Microsoft 070-516 Exam Syllabus Topics:

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 retreives data from Microsoft SQL Server 2008 database named AdventureWorks. The AdventureWorks.dbo.ProductDetails table contains a column names ProductImages that uses a varbinary(max) data type.
You write the following code segment. (Line numbers are included for reference only.)
01 SqlDataReader reader = command.ExecureReader(--empty phrase here --);
02 while(reader.Read())
03 {
04 pubID = reader.GetString(0);
05 stream = new FileStream(...);
06 writer = new BinaryWriter(stream);
07 startIndex = 0;
08 retval = reader.GetBytes(1, startIndex, outByte, 0, bufferSize);
09 while(retval == bufferSize)
10 {
11 ...
12 }
13 writer.Write(outbyte, 0, (int)retval-1);
14 writer.Flush();
15 writer.Close();
16 stream.Close();
17 }
You need to ensure that the code supports streaming data from the ProductImages column. Which code segment should you insert at the empty phrase in line 01?

A) CommandBehavior.Default
B) CommandBehavior.SequentialAccess
C) CommandBehavior.SingleResult
D) CommandBehavior.KeyInfo

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

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to several SQL Server databases. You create a function that modifies customer
records that are stored in multiple databases.
All updates for a given record are performed in a single transaction. You need to ensure that all transactions
can be recovered.
What should you do?

A) Call the EnlistVolatile method of the Transaction class.
B) Call the Reenlist method of the TransactionManager class.
C) Call the EnlistDurable method of the Transaction class.
D) Call the RecoveryComplete method of the TransactionManager class.

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application. You use the Entity Framework Designer to create the following Entity Data Model.

You write a method named ValidatePostalCode to validate the postal code for the application.
You need to ensure that the ValidatePostalCode method is called before the PostalCode property set
method is completed and before the underlying value has changed.
Which code segment should you place in the entity's partial class?

A) public string ValidatedPostalCode
{
set
{
ValidatePostalCode(value);
_PostalCode = value;
}
get
{
return _PostalCode;
}
}
B) partial void OnPostalCodeChanging(string value) {
ValidatePostalCode(value);
}
C) partial void OnPostalCodeChanged(string value) {
PostalCode = GetValidValue<string>(value, "ValidatePostalCode", false, true) ;
}
D) public string ValidatedPostalCode
{
set
{
_PostalCode = StructuralObject.SetValidValue("ValidatePostalCode", false);
}
get
{
return _PostalCode;
}
}

5. 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 application uses a Microsoft
ADO.NET SQL Server managed provider.
When a connection fails, the application logs connection information, including the full connection string.
The information is stored as plain text in a .config file. You need to ensure that the database credentials are
secure.
Which connection string should you add to the .config file?

A) Data Source=myServerAddress; Initial Catalog=myDataBase; User Id=myUsername; Password=myPassword; Persist Security Info=true;
B) Data Source=myServerAddress; Initial Catalog=myDataBase; Integrated Security=SSPI; Persist Security Info=true;
