You create an XML Web service that calculates taxes . You deploy the service to a production computer named YourProduction. The URL of the production XML Web service is http://YourProdution/WS/TaxCalc. asmx.The service does not support all international tax rates. You want to find out which unsupported tax rates are being requested by users. If a user requests a tax rate that is not supported, the service records the request by using a trace message. You then want to view the unsupported rates that have been requested.Which two actions should you take? (Each correct answer presents part of the solution. Choose two)

• 1You create a collection of serviced components that performs bank transfers. All the components are marked with the Transaction (TransactionOption.Required) attribute. All the methods in the components are marked with the AutoComplete () attribute.You discover that incorrect balance amounts are being transferred. You decide to debug the components. During debugging, a System. Runtime.InteropServices.COMException is thrown. The HRESULT for the exception is Ox8004EOO2. The exception includes the following message: "The root transaction wanted to commit but transaction aborted."You find that this exception occurs only during the debugging session, and not when the components run outside of the debugger. This exception is preventing you from continuing to debug the components . You need to resolve this problem.What should you do?

  A.Remove the AutoComplete attribute from each method.Within each method implementation, add calls to the Con- textUtil.SetComplete() and ContextUtil.SetAbort() methods

  B.Remove the AutoComplete attribute from each method.Within each method implementation, add calls to the ContextUtil .MyTransactionVote and ContextUtil, DeactivateOn- Return properties

  C.Increase the transaction timeout in the Component Services tool by using the Properties dialog box for My Computer

  D.Within each method implementation, add calls to the Con- textUtil.SetComplete() and ContextUtil.SetAbort() methodsB.Remove the AutoComplete attribute from each method.Within each method implementation, add calls to the ContextUtil .MyTransactionVote and ContextUtil, DeactivateOn- Return propertiesC.Increase the transaction timeout in the Component Services tool by using the Properties dialog box for My ComputerD.Replace each method implementation with the following segment:Try'Existing method body goes her

• 4You are creating an XML Web service named BankCustomer that provides customer information. You write code to keep track of error messages, warning messages, and informational messages while the service is running. You use the Trace class to write the messages to a log file.On test computers, you want to see error messages and warning messages . On deployment computers, you want to see error messages, but not warning messages.Which code segments should you use? (Each correct answer presents part of the solution. Choose two)

  A.Private mySwitch As New TraceSwitch Sub BankCustomermySwitch = New TraceSwitch ("tswitch", "a trace switch") End Sub

  B.Public Shared level As New TraceLevel Sub BankCustomerlevel = TraceLevel.ErrorEnd SubC .

• 5You create an XML Web service named LatLong that converts street addresses to latitude and longitude coordinates. Your company charges for this service and allows only existing customers to use the service.If a customer is not passed as part of a SOAP header, you want the service to refuse the request. You want these service refusal messages to be logged to an event log named LatLongLog. You anticipate that there will be a lot of these log entries over time. A string object named refusalMessage contains the message to log.Which code segment should you use?

  A.Dim log As New EventLog("LatLongLog")log.WriteEntry(refusalMessage, EventLogEntryType.Error)

  B.Dim log As New EventLog("LatLongLog") log.Source = "LatLongLog"log.WriteEntry(refusalMessage, EventLogEntryType.Error)C . If Not EventLog.SourceExists("LatLongSource") ThenEventLog.CreateEventSource("LatLongSource", "LatLongLog") End IfEventLog.WriteEntry("LatLongSource", refusalMessage, EventLogEntryType .Error)D. If Not EventLog.SourceExists("LatLongSource") ThenEventLog.CreateEventSource ("LatLongSource", "LatLongLog") End IfDim log As New EventLog ("LatLongLog")log.WriteEntry(refusalMessage, EventLogEntryType.Error)
