You use Microsoft Visual Studio 2010 and Microsoft. NET Framework 4 to create an application. The application connects to a Microsoft SQL Server database. You use Entity SQL of the ADO.NE Entity Framework to retrieve data from the database. You need to define a custom function in the conceptual model. You also need to ensure that the function calculates a value based on properties of the object. Which two XML element types should you use? (Each correct answer presents part of the solution. Choose two.)

• A.Association
• B.DefiningExpression
• C.FunctionImport
• D.Function
• E.Dependent

You are creating a Windows Communication Foundation (WCF) service that accepts messages from
clients when they are started.
The message is defined as follows.
[MessageContract] public class Agent {
public string CodeName { get; set; }

public string SecretHandshake { get; set; }
}
You have the following requirements:
"The CodeName property must be sent in clear text.
The service must be able to verify that the property value was not changed after being sent by the client.
"The SecretHandshake property must not be sent in clear text and must be readable by the service. What should you do?

• A.Add an ImmutableObject attribute to the CodeName property and set its value property to true. Add a Browsable attribute to the SecretHandshake property and set its value to false.
• B.Add a MessageBodyMember attribute to the CodeName property and set the ProtectionLevel to Sign. Add a MessageBodyMember attribute to the SecretHandshake property and set the ProtectionLevel to EncryptAndSign.
• C.Add an XmlText attribute to the CodeName property and set the DataType property to Signed. Add a PasswordPropertyText attribute to the SecretHandshake property and set its value to true.
• D.Add a DataProtectionPermission attribute to the each property and set the ProtectData property to true.

You are implementing an ASP.NET page in an e-commerce application. Code in a btnAddToCart_Click
event handler adds a product to the shopping cart.
The page should check the status of the shopping cart and always show a cart icon when one or more
items are in the shopping cart. The page should hide the icon when the shopping cart has no items. You
need to add an event handler to implement this requirement.
Which event handler should you add?

• A.Page_PreRender
• B.Page_PreInit
• C.btnAddToCart_Click
• D.Page_Load

A Windows Communication Foundation (WCF) service has the following contract.
[ServiceContract(Namespace="http://contoso.com")]
public interface IShipping
{ [OperationContract] string DoWork(int id);
}
This is one of several service contracts hosted by your application. All endpoints use SOAP 1.2 bindings
with WS-Addressing 1.0. The System.ServiceModel.MessageLogging trace source in the system.
diagnostics configuration section is configured with one listener.
You need to make sure that only the messages that are returned from the DoWork operation are logged.
Which XML segment should you add to the system.serviceModel/diagnostics/messageLogging/filters
configuration element?

• A.<add xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> //soap:Action[text() = 'http://contoso.com/IShipping/DoWorkResponse'] </add>
• B.<add xmlns:addr="http://www.w3.org/2005/08/addressing"> //addr:Action[text() = 'http://contoso.com/IShipping/DoWork'] </add>
• C.<add xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> //soap:Action[text() = 'http://contoso.com/IShipping/DoWork'] </add>
• D.<add xmlns:addr="http://www.w3.org/2005/08/addressing"> //addr:Action[text() = 'http://contoso.com/IShipping/DoWorkResponse'] </add>

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You are
creating the data layer of the application. You write the following code segment. (Line numbers are included
for reference only.)
01 public static SqlDataReader GetDataReader(string sql){
02 SqlDataReader dr;
03
04 return dr;
05 }
You need to ensure that the following requirements are met:
*The SqlDataReader returned by the GetDataReader method can be used to retrieve rows from the
database.
*SQL connections opened within the GetDataReader method will close when the SqlDataReader is closed.
Which code segment should you insert at line 03?

• A.SqlConnection cnn=new SqlConnection(strCnn); SqlCommand cmd =new SqlCommand(sql, cnn); cnn.Open(); try {
  dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
  }
  catch {
  cnn.Close();
  throw;
  }
• B.SqlConnection cnn=new SqlConnection(strCnn); SqlCommand cmd =new SqlCommand(sql, cnn); cnn.Open(); try {
  dr = cmd.ExecuteReader();
  cnn.Close();
  }
  catch {
  throw;
  }
• C.using (SqlConnection cnn=new SqlConnection(strCnn)){
  try {
  SqlCommand cmd =new SqlCommand(sql, cnn);
  cnn.Open();
  dr = cmd.ExecuteReader();
  }
  catch {
  throw;
  }
  }
• D.SqlConnection cnn=new SqlConnection(strCnn); SqlCommand cmd =new SqlCommand(sql, cnn); cnn.Open(); try {
  dr = cmd.ExecuteReader();
  }
  finally {
  cnn.Close();
  }
