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.

(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.UploadOnly;
• C.customerSyncTable.SyncDirection = SyncDirection.Snapshot;
• D.customerSyncTable.SyncDirection = SyncDirection.DownloadOnly;

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You use

svc );
02
03var q = from c in context.Customers
04where c.City == "London"

• A.context.MergeOption = MergeOption.OverwriteChanges;
• B.context.MergeOption = MergeOption.NoTracking;
• C.context.MergeOption = MergeOption.PreserveChanges;
• D.context.MergeOption = MergeOption.AppendOnly;
