問題4
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application.
The application contains the following code segment. (Line numbers are included for reference only.)
01 class DataAccessLayer
02 {
03 private static string connString;
04
05 ...
06 public static DataTable GetDataTable(string command){
07
08 ...
09 }
10 }
You need to define the connection life cycle of the DataAccessLayer class. You also need to ensure that
the application uses the minimum number of connections to the database.
What should you do?

A. Insert the following code segment at line 07. using (SqlConnection conn = new SqlConnection(connString)){
conn.Open();

private SqlConnection conn = new SqlConnection(connString);
public void Open(){
conn.Open();
}
public void Dispose(){
conn.Close();
}

C. Insert the following code segment at line 04. private static SqlConnection conn = new SqlConnection(connString); public static void Open(){
conn.Open();
}
public static void Close(){
conn.Close();
}

D. Insert the following code segment at line 04. private SqlConnection conn = new SqlConnection(connString); public void Open(){
conn.Open();
}
public void Close(){
conn.Close();
}

問題5
You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server database. The application has two DataTable objects that

04customerOrders.Tables["Customers"].Columns["CustomerID"],
05customerOrders.Tables["Orders"].Columns["CustomerID"]);
06
07customerOrders.Tables["Orders"].Constraints.Add(ordersFK);
You need to ensure that an exception is thrown when you attempt to delete Customer records that have
related Order records. Which code segment should you insert at line 06?

A. ordersFK.DeleteRule = Rule.Cascade;

B. ordersFK.DeleteRule = Rule.SetDefault;

C. ordersFK.DeleteRule = Rule.SetNull;

D. ordersFK.DeleteRule = Rule.None;

正確答案: D

問題6

問題7
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:addr="http://www.w3.org/2005/08/addressing"> //addr:Action[text() = 'http://contoso.com/IShipping/DoWorkResponse'] </add>

B. <add xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> //soap: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/DoWorkResponse'] </add>
