You are developing a Microsoft ASP.NET Web application. The application uses methods of the Trace
class.
You add a TextWriterTraceListener class to the Listeners collection that writes trace messages to a log file.
You need to ensure that the following requirements are met:
The trace messages are written to the TextWriterTraceListener class.
The trace output is accessible only by using the Trace Viewer or by viewing the log file.
Which trace element should you add to the configuration file of the application?

• A. <trace enabled="true" pageOutput="true" writeToDiagnosticsTrace="true"/>
• B. <trace enabled="true" pageOutput="false" writeToDiagnosticsTrace="true"/>
• C. <trace enabled="true" pageOutput="true" writeToDiagnosticsTrace="false"/>
• D. <trace enabled="true" pageOutput="false" writeToDiagnosticsTrace="false"/>

You are developing a Microsoft ASP.NET application.
You add a templated Web user control to a Web Form by using the following code fragment.
<uc1:MyControl ID="MyControl1" runat="server">
<HeaderTemplate>
<asp:Label ID="HeaderLabel" runat="server" />
</HeaderTemplate>
<BodyTemplate>
<asp:TextBox ID="TemplateTextBox" runat="server" />
</BodyTemplate>
</uc1:MyControl>
You write the following code segment in the Web Form's code-behind file. (Line numbers are included for reference only.)
02 protected void Page_Load(object sender, EventArgs e) { 04 }
You need to modify the Visible property of the TemplateTextBox control from the Web Form's code-behind file as false.
What should you do?

• A. Insert the following code segment at line 03. TextBox templateTextBox = (TextBox)MyControl1.FindControl("TemplateTextBox"); templateTextBox.Visible = false;
• B. Insert the following code segment at line 03. TextBox templateTextBox =(TextBox)MyControl1.FindControl("BodyTemplate/TemplateTextBox"); templateTextBox.Visible = false;
• C. Insert the following line of code at line 01. protected TextBox TemplateTextBox = new TextBox(); Insert the following line of code at line 03. TemplateTextBox.Visible = false;
• D. Insert the following line of code at line 01. protected TextBox TemplateTextBox = null; Insert the following code segment at line 03. EnsureChildControls(); TemplateTextBox.Visible = false;

You deploy your company's Internet Web site.
You need to deny anonymous access to the Web site, allowing only authenticated users.
Which code segment should you use?

• A. <authorization> <allow users="*"/> </authorization>
• B. <authorization> <deny users="*"/> </authorization>
• C. <authorization> <deny users="?"/> </authorization>
• D. <authorization> <allow users="?"/> </authorization>

You are creating a Microsoft ASP.NET Web site.
The Web site uses Windows authentication and impersonates authenticated users. You create a method named GetData to access remote resources.
You need to temporarily bypass impersonation while calling GetData.
Which code segment should you use?

• A. Dim winId As WindowsIdentity = WindowsIdentity.GetCurrent(True) Dim ctx As WindowsImpersonationContext = Nothing Try ctx = winId.Impersonate() GetData() Finally ctx.Undo() End Try
• B. Dim winId As WindowsIdentity = DirectCast(HttpContext.Current.User.Identity, WindowsIdentity) Dim ctx As WindowsImpersonationContext = Nothing Try ctx = winId.Impersonate() GetData() Finally ctx.Undo() End Try
• C. <authentication mode="Windows" /> <identity impersonate="false" />
• D. Dim ctx As WindowsImpersonationContext = WindowsIdentity.Impersonate(IntPtr.Zero) Try GetData() Finally ctx.Undo() End Try

You are creating a Web Form.
You need to include a user control on the Web Form.
Which two code segments should you use? (Each correct answer presents part of the solution. Choose two.)

• A. <%@Register TagPrefix="Message" TagName="Fabrikam" Src="UserCtrl1.ascx" %>
• B. <%@Register TagPrefix="Fabrikam" TagName="Message" Src="UserCtrl1.ascx" %>
• C. Control c1 = LoadControl("UserCtrl1.ascx"); c1.Controls.Add(this);
• D. <Fabrikam:Message runat="server"/>
