Suppose You develop a Windows-based application that includes the following code segment. (Linenumbers are included for reference only.)01 Public Sub password_Validating (ByVal sender As _02 Object, ByVal e As _.03 System.ComponentModel.CancelEventArgs)04 Handles password.Validating05 If ValidPassword() = False Then06 Insert new code.07 End If08 End SubYou must ensure that users cannot move control focus away from textPassword ifValidPassword returns a value of False. You will add the required code on line 6.Which code segment should you use?A. e.Cancel = TrueB. sender = textNameC. password.AcceptsTab = FalseD. password.CausesValidation =False

You are creating an XML Web service that processes highly confidential messages. The serviceexposed a Web method named RetrieveMessage that takes as input a code name and returns anencrypted message.You create a SOAP extension and override the extension?s ProcessMessage method so that youcan encrypt the message before it is sent back to the caller.You need to encrypt only the data within the RetrieveMessageResult node of the SOAPresponse. You create a function named EncryptMessage that encrypts theRetrieveMessageResult node. You need to ensure that this method gets called before sendingthe message back to the caller.During which SoapMessageStage should you call EncryptMessage?A. BeforeSerializeB. AfterSerializeC. BeforeDeserializeD. AfterDeserialize

You create a .NET Remoting object named EXPatientinfo that exposes medical patientinformation.Because of the confidential nature of the information, you must ensure that the data remainssecure.You want client applications to connect to EXPatientinfo over a secure communication channel.You want to accomplish this task by writing the minimum amount of code.What should you do?A. Create your own host application and use a TcpChannel and BinaryFormatter.B. Create your own host application and use an HttpChannel and a SoapFormatter.C. Install EXPatientinfo in an Internet Information Services (IIS) virtual directory.Configure EXPatientinfo to use a TcpChannel and a BinaryFormatter.Configure IIS to use SSL.D. Install EXPatientinfo in an Internet Information Services (IIS) virtual directory.Configure EXPatientinfo to use an HttpChannel and a SoapFormatter.Configure IIS to use SSL.

Suppose You create a Windows service that processes XML messages placed in a MSMQ queue. Youdiscover that the service is not functioning properly.You need to debug the service to correct the program.What should you do?A. Start the Windows service.Then attach a debugger to the process.B. Attach a debugger to the Windows service.Then start the Windows service.C. Start the Windows service.Then run the .NET Services Installation tool (Regsvcs.exe).D. Place a breakpoint in the Main method of the Windows service.Then run the application within the Visual Studio .NET integrated development environment(IDE).

You have DataSet object named LoanCustomersDataSet that contains customers serviced by theloan department of XYZ. You receive a second DataSet that contains customers serviced by theasset management department of XYZ. Both objects have the same structure.You want to merge assetCustomersDataSet into LoanCustomersDataSet and preserve theoriginal values in loanCustomersDataSet.Which code segment should you use?A. loanCustomersDataSet.Merge (assetCustomersDataSet)B. loanCustomersDataSet.Merge (assetCustomersDataSet, True)C. assetCustomersDataSet.Merge (loanCustomersDataSet)D. assetCustomersDataSet.Merge (loanCustomersDataSet, True)

You are creating an XML Web service named XYZService. This service has a function namedWriteMessage that writes messages to a flat file in the CEXServiceLog directory..You want to implement security for WriteMessage so that WriteMessage and all the code it callscan write messages only to the EXServiceLog directory.Which code segment should you use?A. Dim filePermission As NewFileIOPermission_(FileIOPermissionAccess.Write, ?CEXServiceLog?)filePermission.Demand()B. Dim filePermission As NewFileIOPermission_(FileIOPermissionAccess.Write, ?CEXServiceLog?)filePermission.Deny()C. Dim filePermission As NewFileIOPermission_(FileIOPermissionAccess.Write, ?CEXServiceLog?)filePermission.PermitOnly()D. Dim filePermission As NewFileIOPermission_(FileIOPermissionAccess.Write, ?CEXServiceLog?)filePermission.Assert()

Suppose You are debugging a visual studio .Net application named XYZApp. The application produces anXml documents object and then consumes the same object. This object moves data in theapplication. The object has no schema, but it contains a declaration line that you must inspect.You decide to transform the XML code and its declaration into a string for easy inspection.What should you do?A. Assign the ToString method of the Xml Document object to a string variable.B. Assign the OuterXml property of the Xml document object to a string variableC. Assign the OuterXml property of the Xml document element property of the Xml documentobject to a string variable.D. Use the WriteContentTo method of the XmlDocument object to write the document into aMemoryStream object. Use the GetXml method of the DataSet object to get a string version ofthe document.

Suppose You are creating an XML Web service that provides a daily quotation from literary works to itscustomers. This quotation is requested in many different languages, thousands of times everyday, and by thousands of Web sites operating many different platform.A Web method named GetEXQuotes takes a languageID as input. GetEXQuotes uses thislanguage ID to retrieve a translated version of the daily quotation from a Microsoft SQL Serverdatabase and to return that quotation to the customer.You want to minimize the time it takes to return the translated version.What should you do?A. Store each translated quotation by using the Cache object.B. Store each translated quotation by using the Session object.C. Set the BufferResponse property of the WebMethod attribute to false.D. Set the CacheDuration property of the WebMethod attribute to an interval greater than zero.

Suppose You create a serviced component named Scheduler. Scheduler is registered in a libraryapplication. The Scheduler methods parse String objects into Date Time objects.You write a console application named EXCoverage.exe to test each method in Scheduler. Youwant Coverage.exe to test Scheduler for multiple cultures to verify its globalization support.What should you do?A. Create a CultureInfo object for each culture locale before calling the Scheduler methods.B. Create a RegionInfo object for each culture locale before calling the Scheduler methods.C. Set the current thread?s CurrentCulture property to each culture locale before calling theScheduler methods.D. Create a EXCoverage.exe.config file and add a <location> element to the configuration file foreach culture locale.

Suppose You are creating an XML Web service named ListBoxService. This service provides content,such as states, countries, and geographical regions, for use in drop-down list boxes.ListBoxService contains a Web method named RetrieveRegionsListBox. This method runs aDataSet object that contains every geographical region in the world.RetrieveRegionsListBox calls a Microsoft SQL Server database to load the DataSet object withregion data. You want to minimize the amount of time the method takes to return to the caller.What should you do?A. Use a stored procedure to return the data.B. Store each DataSet object by using the Session object.C. Set the BufferResponse property of the WebMethod attribute to false.D. Set the CacheDuration property of the WebMethod attribute to an interval greater than zero.
