You need to design a solution for capturing an exception. Which approach should you recommend?

• A. Use a HandleError attribute.
• B. Use an Application_Error method.
• C. Use a Page_Error method.
• D. Use a customErrors element.

You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create an application. The application uses the ADO.NET Entity Framework to manage customer and related 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. Use the Attach method of the ObjectContext to add both Order and Customer entities.
• 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. Set the Value property of the EntityReference of the Order entity.

You use Microsoft Visual Studio 2010 and Microsoft ADO.NET Framework 4 to create an application. 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 ParameterAttribute to the stored procedure function and directly access the strongly typed object from the results collection.
• B. Apply the FunctionAttribute and ResultTypeAttribute to the stored procedure function. Use the GetResult <TElement> method to obtain an enumerator of the correct type.
• 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 <TElement> method to obtain an enumerator of the correct type.

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 Refresh method of ObjectContext by using the RefreshMode.ClientWins method.
• B. Call the query's Execute method by using the MergeOptions.OverwriteChanges option.
• 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.

You are consuming a Windows Communication Foundation (WCF) service in an ASP.NET Web application. The service interface is defined as follows. [ServiceContract] public interface ICatalog {
[OperationContract]
[WebGet(UriTemplate = "/Catalog/Items/{id}",
ResponseFormat = WebMessageFormat.Json)]
string RetrieveItemDescription(int id); } The service is hosted at /Catalog.svc. You need to call the service using jQuery to retrieve the description of an item as indicated by a variable named itemId. Which code segment should you use?

• A. $.get(String.format("/Catalog.svc/Catalog/Items/id={0}", itemId),
  null,
  function (data) {
  ...
  },
  "json");
• B. $.get(String.format("/Catalog.svc/Catalog/Items/?id={0}", itemId) null, function (data) {
  ...
  },
  "javascript");
• C. $.get(String.format("/Catalog.svc/Catalog/Items/{0}", itemId), null, function (data) {
  ...
  },
  "xml");
• D. $.get(String.format("/Catalog.svc/Catalog/Items/{0}", itemId), null, function (data) {
  ...
  },
  "json");
