You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. You create stored procedures by using the following signatures:

“CREATE procedure [dbo].[Product_Insert](@name varchar(50),@price float)
“CREATE procedure [dbo].[Product_Update](@id int, @name varchar(50), @price float)
“CREATE procedure [dbo].[Product_Delete](@id int)
“CREATE procedure [dbo].[Order_Insert](@productId int, @quantity int)
“CREATE procedure [dbo].[Order_Update](@id int, @quantity int,@originalTimestamp timestamp)
“CREATE procedure [dbo].[Order_Delete](@id int)

You create a Microsoft ADO.NET Entity Data Model (EDM) by using the Product and Order entities as shown in the exhibit. You need to map the Product and Order entities to the stored procedures. Which two procedures should you add to the @productId parameter? (Each correct answer presents part of the solution. Choose two.)

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;
03
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?

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 uses the following object query to load a product from the database. (Line numbers are included for reference only.)

01using (AdventureWorksEntities advWorksContext = new AdventureWorksEntities())
02{
03ObjectQuery <Product> productQuery = advWorksContext.Product.Where(“it.ProductID = 900”);
04
05}

You need to log the command that the query executes against the data source. Which code segment should you insert at line 04?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a Windows Communication Foundation (WCF) Data Services service. You deploy the service to the following URL: http://contoso.com/Northwind.svc. You want to query the WCF Data Services service to retrieve a list of customer objects. You need to ensure that the query meets the following requirements: “Only customers that match the following filter criteria are retrieved: City=”Seattle” AND Level > 200. “Data is sorted in ascending order by the ContactName and Address properties. Which URL should you use for the query?

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?

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?

You are designing an ASP.NET Web application that displays daily sales information. The sales information is stored in a large Microsoft SQL Server database. The database information is updated each night. During the day, people use the Web application to display a set of standard sales reports based on the latest database information.
The SQL queries that are required to retrieve the database information can take from 20 to 30 seconds to execute.
You need to design the application to ensure that pages usually load in no more than 5 seconds.
Which two approaches could you recommend? (Each correct answer presents a complete solution. Choose two.)

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 while disconnected from the data store. Changes are submitted to the data store by using the SubmitChanges method of the DataContext object. You receive an exception when you call the SubmitChanges method to submit entities that a user has changed in offline mode. You need to ensure that entities changed in offline mode can be successfully updated in the data store. What should you do?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application updates several Microsoft SQL Server databases within a single transaction. You need to ensure that after a resource failure, you can manage unresolved transactions. What should you do?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application connects to several SQL Server databases. You create a function that modifies customer records that are stored in multiple databases. All updates for a given record are performed in a single transaction. You need to ensure that all transactions can be recovered. What should you do?
