You are creating a document-level solution for Microsoft Office Word 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO).
The solution will insert an XML data island in a Word document. The data island contains the following XML fragment.
< customer id="01AF" >
< region district="Northwest" > < /region >
< /customer >
You bind the data island to an XMLNode instance named xln.
You need to update the region element with the following data.
< customer id="01AF" >
< region district="Southwest" > California < /region >
< /customer >
Which code segment should you use?

• A. If xln.ChildNodes (0).Text = "customer" _ AndAlso xln.NodeText = "Northwest" Then xln.NodeText = "Southwest" xln.ChildNodes (1).Text = "California" End If
• B. If xln.ParentNode.NodeValue = "customer" _ AndAlso xln.NodeText = "Northwest" Then xln.NodeText = "Southwest" xln.ChildNodes (1).Text = " California " End If
• C. If xln.ParentNode.NodeValue = "customer" _ AndAlso xln.NodeValue (0). CompareTo ("Northwest") = 0 Then xln.NodeText = " California " xln.ChildNodes (1).Text = "Southwest" End If
• D. If xln.ChildNodes (0).Text = "customer" _ AndAlso xln.NodeValue (0). CompareTo ("Northwest") = 0 Then xln.NodeText = " California " xln.ChildNodes (1).Text = "Southwest" End If

You create an application by using Visual Studio Tools for the Microsoft Office System (VSTO). The application modifies a Microsoft Office Excel custom workbook. The custom workbook displays the data that is contained in an XML file named Salesorder.xml. The Salesorder.xml file uses an XML schema that is stored in a file named Salesorder.xsd. Both the Salesorder.xml file and the Salesorder.xsd file are located in the C:\Data folder. You need to ensure that the data in the Salesorder.xml file is available for mapping. Which code segment should you use?

• A. Excel.XmlMap map = this.XmlMaps.Add (@"c:\data\Salesorder.xsd", "Root"); this.XmlImport (@"c:\data\Salesorder.xml", out map, true, Globals.Sheet1.Range["A1", Type.Missing ]);
• B. Excel.XmlMap map = this.XmlMaps.Add (@"c:\data\Salesorder.xml", "Root"); this.XmlImportXml (@"c:\data\Salesorder.xsd", out map, false, Globals.Sheet1.Range["A1", Type.Missing ]);
• C. Excel.XmlMap map = this.XmlMaps.Add (@"c:\data\Salesorder.xml", "Root"); this.XmlImport (@"c:\data\Salesorder.xsd", out map, false, Globals.Sheet1.Range["A1", Type.Missing ]);
• D. Excel.XmlMap map = this.XmlMaps.Add (@"c:\data\Salesorder.xsd", "Root"); this.XmlImportXml (@"c:\data\Salesorder.xml", out map, true, Globals.Sheet1.Range["A1", Type.Missing ]);

You create an add-in for Microsoft Office Word by using Visual Studio Tools for the Microsoft Office System (VSTO). You deploy the add-in to a folder on a network share. The folder hosts 20 assemblies. All the assemblies are signed and contain the same digital signature. The add-in runs from a local computer. When the add-in is accessed from a network share by using th e same computer, a security exception is raised. You need to ensure that the add-in can run from the network share. You must achieve this goal without elevating permissions for the other assemblies. What should you do?

• A. Create a code group that is based on the public token that is used to sign the assembly.
• B. Create a code group that is based on the file hash.
• C. Create a code group that is based on the network share URL.
• D. Create a code group that is based on the publisher.

You are creating an add-in for Microsoft Office Word by using Visual Studio Tools for the Microsoft Office System (VSTO). The add-in will display data from a Web service named Service1. Service1 runs on a server named LONDON. The Web service contains a method named GetCustomers that returns a DataSet object. You need to bind the data returned by the GetCustomers method to a DataSet object named ds. Which code segment should you use?

• A. Dim lh As LONDON.Service1 = New LONDON.Service1() Dim ds As DataSet = New DataSet() ds.DataSetName = lh.GetCustomers.GetXml()
• B. Dim lh As LONDON.Service1 = New LONDON.Service1() Dim ds As DataSet = lh.GetCustomers()
• C. Dim lh As LONDON.Service1 = New LONDON.Service1() Dim ds As DataSet = New DataSet() ds.GetXml()
• D. Dim ds As DataSet = New DataSet() Dim mappings As ArrayList = New ArrayList() LONDON.Service1.GenerateXmlMappings( _ ds.GetType(), mappings)
