Microsoft UPG:Transition MCPD.NET Frmwrk 3.5 Web Dev to 4 Web Dev Sample Questions:

1. You are creating a Windows Communication Foundation (WCF) service that is implemented as follows.
(Line numbers are included for reference only.)
01 [ServiceContract]
02 [ServiceBehavior(IncludeExceptionDetailsInFaults = true)]
03 public class OrderService
04 {
05 [OperationContract]
06 public void SubmitOrder(Order anOrder)
07 {
08 try
09 {
10 ...
11 }
12 catch(DivideByZeroException ex)
13 {
14
15 }
16 }
17 }
You need to ensure that the stack trace details of the exception are not included in the error information
sent to the client.
What should you do?

A) Replace line 14 with the following line.
throw new FaultException<Order>(anOrder, ex.ToString());
B) After line 05, add the following line. [FaultContract(typeof(FaultException<Order>))] Replace line 14 with the following line. throw new FaultException<Order>(anOrder, "Divide by zero exception");
C) Replace line 14 with the following line. throw;
D) After line 05, add the following line. [FaultContract(typeof(FaultException<Order>))] Replace line 14 with the following line. throw ex;

2. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application uses the ADO.NET Entity Framework to model entities. The application allows users to make
changes to entities while disconnected from the central data store.
You need to ensure that when the user connects to the central data store and retrieves new data, the
application meets the following requirements:
*Changes made to the local data store in disconnected mode are preserved.
*Entities that have already been loaded into the local data store, but have not been modified by the user,
are updated with the latest data.
What should you do?

A) Call the query's Execute method by using the MergeOptions.OverwriteChanges option.
B) Call the Refresh method of ObjectContext by using the RefreshMode.ClientWins method.
C) Call the query's Execute method by using the MergeOptions.AppendOnly option.
D) Call the Refresh method of ObjectContext by using the RefreshMode.StoreWins option.

3. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The
application connects to a Microsoft SQL Server 2008 database.
The database includes a database table named ProductCatalog as shown in the exhibit. (Click the Exhibit
button.)
You add the following code segment to query the first row of the ProductCatalog table. (Line numbers are
included for reference only.)
01 using (var cnx = new SqlConnection(connString))
02 {
03 var command = cnx.CreateCommand();
04 command.CommandType = CommandType.Text;
05 command.CommandText ="SELECT TOP 1 * FROM dbo.ProductCatalog";
06 cnx.Open();
07 var reader = command.ExecuteReader();
08 if (reader.Read()) {
09 var id = reader.GetInt32(0);
10
11 reader.Close();
12 }
13 }
You need to read the values for the Weight, Price, and Status columns.
Which code segment should you insert at line 10?
Exhibit:

A) var weight = reader.GetDecimal(1); var price = reader.GetFloat(2); var status = reader.GetByte(3);
B) var weight = reader.GetDouble(1); var price = reader.GetFloat(2); var status = reader.GetBoolean(3);
C) var weight = reader.GetFloat(1); var price = reader.GetDouble(2); var status = reader.GetByte(3);
D) var weight = reader.GetDouble(1); var price = reader.GetDecimal(2); var status = reader.GetBoolean(3);

4. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a Windows Communication Foundation (WCF) Data Services service. The service connects to a Microsoft SQL Server 2008 database. The service is hosted by an Internet Information Services (IIS) 6.0 server. You need to ensure that applications authenticate against user information stored in the database before the application is allowed to use the service. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Configure IIS to require basic authentication.
B) Modify the Data Services service to use a Microsoft ASP.NET membership provider.
C) Configure IIS to require Windows authentication.
D) Enable the WCF Authentication Service.
E) Configure IIS to allow anonymous access.

5. You use Microsoft Visual Studio 2010, Microsoft Sync Framework, and Microsoft .NET Framework 4 to create an application. You have a ServerSyncProvider connected to a Microsoft SQL Server database. The database is hosted on a Web server. Users will use the Internet to access the Customer database through the ServerSyncProvider. You write the following code segment. (Line numbers are included for reference only.)
01SyncTable customerSyncTable = new SyncTable("Customer"); 02customerSyncTable.CreationOption = TableCreationOption. UploadExistingOrCreateNewTable;
04customerSyncTable.SyncGroup = customerSyncGroup; 05 this.Configuration.SyncTables.Add(customerSyncTable);
You need to ensure that the application meets the following requirements: "Users can modify data locally and receive changes from the server. "Only changed rows are transferred during synchronization. Which code segment should you insert at line 03?

A) customerSyncTable.SyncDirection = SyncDirection.Bidirectional;
B) customerSyncTable.SyncDirection = SyncDirection.DownloadOnly;
C) customerSyncTable.SyncDirection = SyncDirection.Snapshot;
D) customerSyncTable.SyncDirection = SyncDirection.UploadOnly;
