1 Question: 1 You are creating a distributed application by using Microsoft.NET Framework 3.5. You use Windows Communication Foundation (WCF) to create the application. The operations provided by the WCF server use the remote resources of other computers. These methods use the credentials provided by the client applications. You need to ensure that the WCF server can impersonate the client applications to access the remote resources. Which client application settings should you use? A. <windows allowedimpersonationlevel="delegation"/> B. <windows allowedimpersonationlevel="impersonation"/> C. <windows allowedimpersonationlevel="identification"/> D. <windows allowedimpersonationlevel="impersonation" allowntlm="false"/> Answer: A Question: 2 You are creating a Windows Communication Foundation (WCF) service by using Microsoft.NET Framework 3.5. You need to host the WCF service on the IIS Web server. First, you create a new folder for your application files. Next, you use the IIS management tool to create a Web application in the new folder. Which three actions should you perform next? (Each correct answer presents part of the solution. Choose three.) A. Create a web.config file that contains the appropriate configuration code. Place this file in the application folder. B. Create a web.config file that contains the appropriate configuration code. Place this file in the same folder as your service contract code. C. Create a service file that has the.svc extension containing directive information for the service. Move this file to the application folder. D. Create a service file that has the.svc extension containing directive information for the service. Move this file to the application folder. E. Create a vti_bin sub-folder within the application folder for your code files. Place the code file that defines and implements the service contract in this folder. F. Create an App_Code sub-folder within the application folder for your code files. Place the code file that defines and implements the service contract in this folder. Answer: A, D, F Question: 3 Framework 3.5.

GetData/n for the index value n Which code segment should you insert at line 05? A. [WebGet(UriTemplate="GetData/{index}", BodyStyle=WebMessageBodyStyle.Bare)] B. [WebGet(UriTemplate="GetData?index={index}", BodyStyle=WebMessageBodyStyle.Bare)] C. [WebGet(UriTemplate="GetData/[index]", BodyStyle=WebMessageBodyStyle.Bare)] D. [WebGet[UriTemplate="GetData?index={index}", BodyStyle=WebMessageBodyStyle.Bare]] Answer: A Question: 78 Framework 3.5. The service will contain an enumeration named OrderState. The OrderState enumeration will contain the following four values: Processing Cancelled Confirmed Closed Page 34 of 41

35 The client application must be able to set the state of an Order entity to only the following two values: Cancelled Closed You need to create the data contract for OrderState. Which code segment should you use? A. [DataContract]public enum OrderState{ Processing=1, [DataMember] Cancelled=2, [DataMember] Confirmed=3, Closed=4} B. [DataContract]public enum OrderState{ Processing=1, [EnumMember] Cancelled=2, Confirmed=3, [EnumMember] Closed=4} C. [DataContract]public enum OrderState{ [EnumMember(Value="False")] Processing=1, [EnumMember(Value="True")] Cancelled=2, [EnumMember(Value="True")] Confirmed=3, [EnumMember(Value="False")] Closed=4} D. [DataContract]public enum OrderState{ [DataMember] Processing=1, [DataMember(IsRequired=true)] Cancelled=2, [DataMember] Confirmed=3, [DataMember(IsRequired=true)] Closed=4} Question: 79 You are creating a Windows Communication Foundation (WCF) service by using Microsoft.NET Framework 3.5. You configure a binding to enable streaming. You need to ensure that the client application is able to stream large XML files to the WCF service. Which operation contract should you create? A. [OperationContract]void UploadFile(Stream xmldata); B. [OperationContract]void UploadFile(XmlWriter xmldata); C. [OperationContract]void UploadFile(StreamWriter xmldata); D. [OperationContract]void UploadFile(byte[] xmldata); Answer: A Question: 80 Framework 3.5. The service has an operation contract named GetMessage. You write the following code segment to implement the service. (Line numbers are included for reference only.) 01 public Message GetMessage() 02 { 03 Message msg=null; 04 string action="getmessageresponse"; 05 MessageVersion ver=messageversion.default; 06 FileStream stream=new FileStream(@"D:\File.xml", 07 FileMode.OpenOrCreate); return msg; 10 } You need to send the contents of the File.xml file to a client application by using the SOAP body. Which code segment should you insert at line 08? A. msg=message.createmessage(ver, action, stream); Page 35 of 41

36 B. XmlReader reader=xmlreader.create(stream);msg=message.createmessage(ver, action, reader); C. XmlWriter writer=xmlwriter.create(stream);msg=message.createmessage(ver, action, writer); D. XmlObjectSerializer ser=new DataContractSerializer(typeof(XmlDocument));msg=Message.CreateMessage(ver, action, stream, ser); Question: 81 You create a Windows Communication Foundation service by using Microsoft.NET Framework 3.5. You write the following code segment. (Line numbers are included for reference only.) 01 [ServiceContract(SessionMode=SessionMode.Required)] 02 public interface IOrderManager 03 { void CloseOrder(); 06 } You need to decorate the operation as the method that closes the current session. Which code segment should you insert at line 04? A. [OperationContract(IsInitiating=false)] B. [OperationContract(IsTerminating=true)] C. [OperationContract][OperationBehavior(ReleaseInstanceMode= ReleaseInstanceMode.AfterCall)] D. [OperationContract(IsTerminating=false)][OperationBehavior(ReleaseInstanceMode= ReleaseInstanceMode.AfterCall)] Question: 82 You create a Windows Communication Foundation client application by using Microsoft.NET Framework 3.5. The client application communicates with an existing Web service that requires custom HTTP headers. You need to ensure that all messages sent to the service include the headers. Which two tasks should you perform? (Each correct answer presents part of the solution. Choose two.) A. Create a message inspector. Insert the custom headers by using the IClientMessageInspector.AfterReceiveReply method. B. Create a message inspector. Insert the custom headers by using the IClientMessageInspector.BeforeSendRequest method. C. Create a custom endpoint behavior. Add the message inspector by using the IEndpointBehavior.ApplyClientBehavior method. D. Create a custom endpoint behavior. Add the message inspector by using the IEndpointBehavior.AddBindingParameters method., C Question: 83 You create an application by using Microsoft Visual Studio.NET 2008 andthe.net Framework 3.5. You plan to create the presentation layer of the application. Users will access the application Page 36 of 41

37 on Windows Vista client computers that have the.net Framework 3.5 installed. You need to ensure that the application meets the following requirements: It runs in Microsoft Internet Explorer. It provides maximum usability by using 3D graphics and animations. It does not require additional components to be installed on the client computers. What should you do? A. Use a Microsoft ASP.NET application. B. Use a Microsoft Silverlight application. C. Use Windows Presentation Foundation Browser Application. D. Use a Windows Presentation Foundation application along with the ClickOnce deployment. Question: The application stores human resources data in a Microsoft SQL Server 2008 database. A partial database schema is as shown in the exhibit. (Click the Exhibit button.) Each time a row is added, modified, or deleted from the Employee table, a corresponding entry must be recorded in the EmployeeChangeLog table. You need to implement the data change logging. What should you do? A. Create a trigger on the Employee table. B. Add a user-defined function to the database. C. Add a CHECK constraint to the Employee table. D. Create a foreign key on the EmployeeChangeLog table that references the Employee table. Answer: A Question: The ASP.NET application connects to a shared Microsoft SQL Server 2008 database instance. The application requires certain changes in the relationships represented in the data. Page 37 of 41
