back.
What are two possible TransactionScope constructors that you can use for the inner transaction to achieve
this goal?
(Each correct answer presents a complete solution. Choose two.)

QUESTION NO: 6
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create a Microsoft ASP.NET
application.
You want to connect the application to a Microsoft SQL Server Express 2008 database named
MyDatabase.
The primary database file is named MyDatabase.mdf and it is stored in the App_Data folder.
You need to define the connection string. Which connection string should you add to the Web.config file?

QUESTION NO: 7
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?

QUESTION NO: 8
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application connects to a Microsoft SQL Server database. The application uses the ADO.NET Entity
Framework to model entities.
The database includes objects based on the exhibit (click the Exhibit button).
The application includes the following code segment. (Line numbers are included for reference only.)
01 using(AdventureWorksEntities context = new AdventureWorksEntities())
02 {
03 ...
04 foreach (SalesOrderHeader order in customer.SalesOrderHeader)
05 {
06 Console.WriteLine(String.Format("Order: {0} ",
order.SalesOrderNumber));
07 foreach (SalesOrderDetail item in order.SalesOrderDetail)
08 {
09 Console.WriteLine(String.Format("Quantity: {0} ", item.Quantity));
10 Console.WriteLine(String.Format("Product: {0} ",
item.Product.Name));
11 }
12 }
13 }
You want to list all the orders for a specific customer. You need to ensure that the list contains following fields:
-Order number
-Quantity of products
-Product name
Which code segment should you insert in line 03?

QUESTION NO: 9
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
The application uses the ADO.NET Entity Framework to model entities.
You need to create a database from your model. What should you do?

QUESTION NO: 10
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to develop an application that connects to a Microsoft SQL Server 2008 database. You add the following table to the database.
CREATE TABLE ObjectCache ( Id INT IDENTITY PRIMARY KEY, SerializedObjectData XML)
You write the following code segment to retreive records from the ObjectCache table. (Line numbers are included for reference only.)
01 string s = GetConnectionStringFromConfigFile("xmldb");
02 using (SqlConnection conn = new SqlConnection(s))
03 using (SqlCommand cmd = new SqlCommand("select * from ObjectCache",
conn))
04 {
05 conn.Open();
06 SqlDataReader rdr = cmd.ExecuteReader();
07 while(rdr.Read())
08 {
09 ...
10 DeserializeObject(obj);
11 }
12 }
You need to retreive the data from the SerializedObjectData column and pass it to a method named
DeserializeObject.
Which line of code should you insert at line 09?

QUESTION NO: 11
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4.0 to create an application.
You create a stored procedure to insert a new record in the Categories table according to following code
segment.
CREATE PROCEDURE dbo.InsertCategory @CategoryName navrchar(15),
@Identity int OUT
AS INSERT INTO Categories(CategoryName) VALUES (@CategoryName) SET @Identity = SCOPE_IDENTITY() RETURN @@ROWCOUNT
You add the following code fragment. (Line numbers are included for reference only.)
01 private static void ReturnIdentity(string connectionString)
02 {
03 using(SqlConnection connection = new SqlConnection(connectionString))
04 {
05 SqlDataAdpater adapter = new SqlDataAdapter("SELECT CategoryID,
CategoryName FROM dbo.Categories", connection);
06 adapter.InsertCommand = new SqlCommand("InsertCategory", connection);
07 adapter.InsertCommand.CommandType = CommandType.StoredProcedure;
08 SqlParameter rowcountParameter = adapter.InsertCommand.Parameters.Add
("@RowCount", SqlDbType.Int);
09 ...
10 adapter.InsertCommand.Parameters.Add("@CategoryName", SqlDbType.NChar,
15, "CategoryName");
11 SqlParameter identityParameter = adapter.InsertCommand.Parameters.Add
("@Identity", SqlDbType.Int, 0, "CategoryID");
12 ...
13 DataTable categories = new DataTable();
14 adapter.Fill(categories);
15 DataRow ctegoryRow = categories.NewRow();
16 categoryRow["CategoryName"] = "New beverages";
17 categories.Rows.Add(categoryRow);
18 adapter.Update(categories);
19 Int32 rowCount = (Int32)adapter.InsertCommand.Parameters
["@RowCount"].Value;
20 }
21 }
Which code elements needs to be added in the empty lines?

QUESTION NO: 12
You use Microsoft .NET Framework 4.0 to develop an ASP.NET 4 Web application.
You need to encrypt the connection string information that is stored in the web.config file. The application is
deployed to multiple servers.
The encryption keys that are used to encrypt the connection string information must be exportable and
importable on all the servers.
You need to encrypt the connection string section of the web.config file so that the file can be used on all of
the servers.
Which code segment should you use?
