Microsoft 070-523 Exam Syllabus Topics:

Microsoft UPG:Transition MCPD.NET Frmwrk 3.5 Web Dev to 4 Web Dev Sample Questions:

1. You use Microsoft Visual Studio 2010 and Microsoft .NET Framework 4 to create a Windows Communication Foundation (WCF) Data Services service. The service connects to a Microsoft SQL Server 2008 database. The service is hosted by an Internet Information Services (IIS) 6.0 Web server.
The application works correctly in the development environment. However, when you connect to the service on the production server, attempting to update or delete an entity results in an error. You need to ensure that you can update and delete entities on the production server. What should you do?

A) Add the following line of code to the InitializeService method of the service. config.SetEntitySetAccessRule ("*",EntitySetRights.WriteDelete | EntitySetRights.WriteMerge);
B) Add the following line of code to the InitializeService method of the service. config.SetEntitySetAccessRule ("*",EntitySetRights.WriteDelete | EntitySetRights.WriteInsert);
C) Configure IIS to allow the POST and DELETE verbs for the .svc Application Extension.
D) Configure IIS to allow the PUT and DELETE verbs for the .svc Application Extension.

2. 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) 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 Attach method of the ObjectContext to add both Order and Customer entities.
D) Use the AddObject method of the ObjectContext to add both Order and Customer entities.

3. 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?

A) Set the ObjectTrackingEnabled property of DataContext to true.
B) Call the SubmitChanges method of DataContext with a value of System.Data.Linq.ConflictMode. ContinueOnConflict.
C) Set the DeferredLoadingEnabled property of DataContext to true.
D) Call the SaveChanges method of DataContext with a value of false.

4. A WCF service code is implemented as follows. (Line numbers are included for reference only.)

07Public Function Calculate(ByVal op1 As Double,
08ByVal op As String, ByVal op2 As Double) As Double
...
24End Function

26End Class
You need to increase the rate by which clients get the required response from the service.
What are two possible ways to achieve this goal? (Each correct answer presents a complete solution.
Choose two.)

A) Change the service behavior to the following. <ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)>
B) Change the service behavior to the following. <ServiceBehavior( InstanceContextMode:=InstanceContextMode.Single, ConcurrencyMode:=ConcurrencyMode.Multiple)>
C) Require the clients to use async operations when calling the service.
D) Require the clients use threads, the Parallel Task Library, or other mechanism to issue service calls in parallel.

5. Four Windows Communication Foundation (WCF) services are hosted in Microsoft Internet Information
Services (IIS). No behavior configuration exists in the web.config file.
You need to configure the application so that every service and endpoint limits the number of concurrent
calls to 50 and the number of concurrent sessions to 25.
Which XML segment should you add to the system.serviceModel configuration section of the web.config
file?

A) <behaviors> <serviceBehaviors> <behavior name="*"> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="25"/> </behavior>
</serviceBehaviors>
</behaviors>
B) <behaviors> <serviceBehaviors> <behavior name="ALL"> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="25"/> </behavior>
</serviceBehaviors>
</behaviors>
C) <behaviors> <serviceBehaviors> <behavior name="default"> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="25"/> </behavior>
</serviceBehaviors>
</behaviors>
D) <behaviors> <serviceBehaviors> <behavior name=""> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="25"/> </behavior>
</serviceBehaviors>
