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 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?

A

Call the query's Execute method by using the MergeOptions.AppendOnly option.

B

Call the query's Execute method by using the MergeOptions.OverwriteChanges option.

C

Call the Refresh method of ObjectContext by using the RefreshMode.StoreWins option.

D

Call the Refresh method of ObjectContext by using the RefreshMode.ClientWins method.

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?

A

Set the Value property of the EntityReference of the Order entity.

B

Call the Add method on the EntityCollection of the Order entity.

C

Use the AddObject method of the ObjectContext to add both Order and Customer entities.

D

Use the Attach method of the ObjectContext to add both Order and Customer entities.

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?

A

context.MergeOption = MergeOption.AppendOnly;

B

context.MergeOption = MergeOption.PreserveChanges;

C

context.MergeOption = MergeOption.OverwriteChanges;

D

context.MergeOption = MergeOption.NoTracking;

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?

A

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

B

Apply the FunctionAttribute and ParameterAttribute to the stored procedure function and directly access the strongly typed object from the results collection.

C

Apply the ResultTypeAttribute to the stored procedure function and directly access the strongly typed object from the results collection.

D

Apply the ParameterAttribute to the stored procedure function. Use the GetResult

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?

A

an X-HTTP-Method header as part of a POST request

B

an X-HTTP-Method header as part of a GET request

C

an HTTP ContentType header as part of a POST request

D

an HTTP ContentType header as part of a GET request

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?

A

DSACryptoServiceProvider

B

AESCryptoServiceProvider

C

MD5CryptoServiceProvider

D

SHA1CryptoServiceProvider

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?

A

?Server=XYZ01;Data Source=Factory; Initial Catalog=FactoryDB;Integrated Security=SSPI?

B

?Server=XYZ01;Data Source=Factory; Database=FactoryDB;Integrated Security=SSP1?

C

?Data Source=XYZ01\\Factory; Initial Category=Factory; Integrated Security=SSP1?

D

?Data Source=XYZ01\\Factory; Database=FactoryDB; Integrated Security=SSP1?

The assembly also writes and reads values to and from the Windows registry while it is being consumed. The assembly will be distributed to client computers by using your company, XYZ, intranet. All client computers are configured to implement the default .NET security policy. You need to implement security in the assembly. What should you do?

A

Implement declarative security and execute the permission demand to allow access to the file system and Windows registry.

B

Implement declarative security and execute the minimum permission request to allow access to the file system and Windows registry.

C

Implement imperative security and execute the permission demand to allow access to the file system and Windows registry.

D

Implement imperative security and execute the minimum permission request to allow access to the file system and Windows registry.
