You use Microsoft Visual Studio 2010 and Microsoft ADO.NET Framework 4 to create anapplication. The application connects to a Microsoft SQL Server 2008 database. You use the ADO.NET LINQ to SQL model to retrieve data from the database. You use stored procedures to return multiple result sets. You need to ensure that the result sets are returned as strongly typed values. What should you do?

Correct Answer: Apply the FunctionAttribute and ResultTypeAttribute to the stored procedure function. Use the GetResult

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create anapplication. The application uses the ADO.NET Entity Framework to model entities. Theapplication 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?

You are the administrator of a SQL Server 2000 computer. The server contains a database named FinanceData that is used by a client/server application. Each employee has a SQL Server login that the application uses to access the server.Your company hires a new employee named Andrew. You create a SQL Server login named Andrew. You also create a database user named Andrew in the database and grant the database user full permissions in the database.Whenever Andrew runs the client/server application, he receives the following error message: "Invalid object name." Andrew also reports that he cannot access the database by using the application.You need to ensure that Andrew can use the application. Which Transact-SQL statement should you execute?

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 stores encrypted credit card numbers in the database. You need to ensure that credit card numbers can be extracted from the database.
Which cryptography provider should you use?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an
application. You use the ADO.NET Entity Framework to model entities. You write the following code segment. (Line numbers are included for reference only.)
01AdventureWorksEntities context = New AdventureWorksEntities
02
03var q = from c in context.Customers
04where c.City == "London"
05orderby c.CompanyName
06select c;
You need to ensure that the application meets the following requirements: "Compares the current values of unmodified properties with values returned from the data source". Marks the property as modified when the properties are not the same. Which code segment should you insert at line 02?

You are a Web developer for XYZ. You create an ASP.NET application that accesses sales and marketing data. The data is stored in a Microsoft SQL Server 2000 database on a server named XYZ01.
The company purchases a factory automation software application. The application is installed on XYZ01, where it creates a second instance of SQL Server 2000 named Factory and a database named FactoryDB. You connect to FactoryDB by using Windows Integrated authentication.
You want to add a page to your ASP.NET application to display inventory data from FactoryDB. You use a SqlConnection object to connect to the database. You need to create a connection string to FactoryDB in the instance of SQL Server named Factory on XYZ01. Which string should you use?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a WindowsCommunication Foundation (WCF) Data Services service. You discover that when anapplication submits a PUT or DELETE request to the Data Services service, it receives an error. You need to ensure that the application can access the service. Which header and request type should you use in the application?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create anapplication. The application uses the ADO.NET Entity Framework to manage customer andrelated order records. You add a new order for an existing customer. You need to associate the Order entity with the Customer entity. What should you do?

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create anapplication. You use the ADO.NET Entity Data Model (EDM) to define a Customer entity. Youneed to add a new Customer to the data store without setting all the customer's properties. What should you do?

You plan to deploy your ASP.NET application over XYZs intranet. The application uses data retrieved from a Microsoft SQL Server database. You want to use SQL Server connection pooling to optimize performance. You also need to protect confidential data stored on the server while minimizing administrative costs. You need to configure security for your application. What should you do?

You develop an enterprise application, called XYZApplication that includes a Windows Form presentation layer, middle-tier components for business logic and data access, and a Microsoft SQL Server database.
You are in the process of creating a middle-tier component that will execute the data access routines in your application. When data is passed to this component, the component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction.
The code for the middle-tier component will implement the following objects:
SqlConnection cn = new SqlConnection();
SqlTransaction tr;
If two users try to update the same data concurrently, inconsistencies such as phantom reads will occur. You must now add code to your component to specify the highest possible level of protection against such inconsistencies.
