You create a Microsoft ASP.NET application by using the Microsoft .NET Framework
version 3.5. The application contains two Web pages named OrderDetails.aspx and
OrderError.htm.If the application throws unhandled errors in the OrderDetails.aspx Web
page, a stack trace is displayed to remote users.You need to ensure that the OrderError.htm
Web page is displayed for unhandled errors only in the OrderDetails.aspx Web page. What
should you do?

A.
Set the Page attribute for the OrderDetails.aspx Web page in the following manner.
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”OrderDetails.aspx.cs”
Inherits=”OrderDetails” %> Add the following section to the Web.config file.
<customErrors mode=”Off” defaultRedirect=”OrderError.htm”>
</customErrors>

B.
Set the Page attribute for the OrderDetails.aspx Web page in the following manner.
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”OrderDetails.aspx.cs”
Inherits=”OrderDetails” Debug=”true” %> Add the following section to the Web.config file.
<customErrors mode=”On” defaultRedirect=”OrderError.htm”>

C.
Set the Page attribute for the OrderDetails.aspx Web page in the following manner.
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”OrderDetails.aspx.cs”
Inherits=”OrderDetails” ErrorPage=”~/OrderError.htm” Debug=”false” %>
Add the following section to the Web.config file.
<customErrors mode=”On”>
</customErrors>

D.
Set the Page attribute for the OrderDetails.aspx Web page in the following manner.
<%@ Page Language=”C#” AutoEventWireup=”true” CodeFile=”OrderDetails.aspx.cs”
Inherits=”OrderDetails” Debug=”true” ErrorPage=”~/OrderError.htm” %>
Add the following section to the Web.config file.
<customErrors mode=”Off”>
</customErrors>

Explanation:
customErrors must be set to on without a defaultRedirect since the ErrorPage is explicitly specified in the Page directive.
