You are creating a Microsoft ASP.NET Web application that allows customers to transfer money between their bank accounts.
You write the following code segment. (Line numbers are included for reference only.)
01 Using cn As New SqlConnection()
02 cn.ConnectionString = strConnString
03 cn.Open()
04 Using tran As SqlTransaction = cn.BeginTransaction()
05 Try
07 Catch xcp As Exception
08 lblMessage.Text = xcp.Message
09 tran.Rollback()
10 End Try
11 End Using
12 End Using
You need to ensure that the transfer operation executes within a transaction.
Which code segment should you insert at line 06?

• A. Using cmd As SqlCommand = cn.CreateCommand() cmd.Transaction = tran cmd.CommandText = ("UPDATE Accounts SET Bal = Bal " & Xfer & " WHERE Acct = ") + Acct1 cmd.ExecuteNonQuery() cmd.CommandText = ("UPDATE Accounts SET Bal = Bal + " & Xfer & " WHERE Acct = ") + Acct2 cmd.ExecuteNonQuery() End Using
• B. Using cmd As SqlCommand = cn.CreateCommand() cmd.Transaction = tran cmd.CommandText = ("UPDATE Accounts SET Bal = Bal " & Xfer & " WHERE Acct = ") + Acct1 cmd.ExecuteNonQuery() cmd.CommandText = ("UPDATE Accounts SET Bal = Bal + " & Xfer & " WHERE Acct = ") + Acct2 cmd.ExecuteNonQuery() End Using tran.Commit()
• C. Using cmd As SqlCommand = cn.CreateCommand() cmd.CommandText = ("UPDATE Accounts SET Bal = Bal " & Xfer & " WHERE Acct = ") + Acct1 cmd.ExecuteNonQuery() cmd.CommandText = ("UPDATE Accounts SET Bal = Bal + " & Xfer & " WHERE Acct = ") + Acct2 cmd.ExecuteNonQuery() End Using
• D. Using cmd As SqlCommand = cn.CreateCommand() cmd.CommandText = ("UPDATE Accounts SET Bal = Bal " & Xfer & " WHERE Acct = ") + Acct1 cmd.ExecuteNonQuery() cmd.CommandText = ("UPDATE Accounts SET Bal = Bal + " & Xfer & " WHERE Acct = ") + Acct2 cmd.ExecuteNonQuery() End Using tran.Commit()

You write a Web application that uses registry entries for its configuration settings.

You are creating a Microsoft ASP.NET Web site. The Web site supports different sub-sites.
The Web site has a master page named Parent.master.
The master page contains the following code fragment.
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="Parent.master.cs"
Inherits="Parent" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<h1> Parent Master</h1>
<asp:contentplaceholder id="MainContent" runat="server">
</asp:contentplaceholder>
</div>
</form>
</body>
</html>
You write the following code fragment. (Line numbers are included for reference only.) 02 <asp:Panel runat="server" ID="panel1" BackColor="Aqua">
03 <h1> Subsite Master</h1>
04 <asp:ContentPlaceHolder ID="SubsiteContent1" runat="server">
05 </asp:ContentPlaceHolder>
06 </asp:Panel>
07 </asp:Content>
You need to create a nested master page named SubSite.master.
Which code fragment should you insert at line 01?

• A. <%@ Master Language="C#" MasterPageFile="~/Parent.master" %> <asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
• B. <%@ Master Language="C#" MasterPageFile="~/Parent.master" %> <asp:Content ID="Content1" ContentPlaceHolderID="SubSiteContent" runat="server">
• C. <%@ Master Language="C#" Inherits="Parent" %> <asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
• D. <%@ MasterType VirtualPath="~/Parent.master" %> <asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
