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.

How to create a serviced component named SessionDispenser. This computer is in the XYZ.Utilitiesassembly and is registered in a COM+ server application. SessionDispenser has multiple callers.You discover that there are logic problems in the Create New Session method. You want todebug any calls to this method.What should you do?A. Open the SessionDispenser solution.Set a breakpoint on the CreateNewSession method.Start the debugger.B. Attach the debugger to the client process.Set a breakpoint on the SessionDispenser.CreateNewSession method.C. Attach the debugger to the XYZ.Utilites.exe process.Set a breakpoint on the CreateNewSession method.D. Attach the debugger to a Dllhost.exe process.Set a breakpoint on the CreateNewSession method.

Suppose You are planning to create a DataSet object named EXDataSet to be used in a bond-tradingapplication.Several developers will need to write code to manipulate EXDataSet, and you want to ensure thatmyDataSet is easy for them to use. You decide to create EXDataSet as a strongly typed data set.Which two actions should you take? (Each correct answer presents part of the solution. Choosetwo)A. Create an XSD schema that defines EXDataSet.B. Create an XDR schema that defines EXDataSet.C. Create a class for EXDataSet that is based on the schema and that inherits from the DataSetclass.D. Create a class for EXDataSet that is based on the schema and that inherits from theXmlSchema class.E. Create a key pair for EXDataSet by using the Strong Name tool (Sn.exe).

Your company frequently receives product information from external vendors in the form of XMLdata.You receive XML document files, an .xdr schema file, and an .xsd schema file.You need to write code that will create a typed DataSet object on the basis of product information.Your code will be used in several Visual studio .NET applications to speed up data processing.You need to create this code as quickly as possible.What should you do?A. Create the code manually.B. Use XmlSerializer.Serialize to generate the code.C. Use the XmlSerializer.Deserialize to generate the code.D. Use the Xml Schema Definition tool (Xsd.exe) to generate the code.

You have a DataSet object named myDataSet. This object contains two DataTable objectsnamed Customers and Orders. Customers has a column named CustomerID, which is unique toeach customer.Orders also has a column named CustomerID. You want to use the GetChildRows method of theDataRow object to get all orders for the current customers.What should you do?A. Add a foreign key constraint on CustomerID of Orders between Customers and Orders.B. Add a data relation to myDataSet on OrderID between Customers and Orders.C. Create a unique constraint on CustomerID of Customers..D. Create a primary key on CustomerID of Customers.
