• 1You 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)

• 2You create an XML Web service that uses the Trace class to output error messages, warning messages, and informational messages to a log file. The service uses a TraceSwitch object to filter the trace output.The DisplayName property of the TraceSwitch object is "globalSwitch". On a development computer, all trace output appears in the log file.You move the service to a production computer. You must configure the production XML Web service to output only error messages to the log file.What should you do?

  A.To the We

  B.config file, add the following code segment: Odd name=" global Switch" value=,'l"/>

  C.To the Web.config file, add the following code segment: Odd name*"TraceSwitch" value=nln/>

• 8You 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
