You create a Microsoft ASP.NET application by using the Microsoft .NET Framework
version 3.5.You plan to submit text that contains HTML code to a page in the
application.You need to ensure that the HTML code can be submitted successfully without
affecting other applications that run on the Web server.What should you do?

A.
Add the following attribute to the @Page directive. EnableEventValidation=”true”

B.
Add the following attribute to the @Page directive. ValidateRequest=”true”

C.
Set the following value in the Web.config file.
<system.web>
<pages validateRequest=”false”/>
</system.web>

D.
Set the following value in the Machine.config file.
<system.web>
<pages validateRequest=”false”/>
</system.web>

Explanation:
Since this needs to apply to the entire application rather than a single .aspx page, the change should be made to the Web.config file. Web.config changes only affect the local application/virtual directory and not the entire web server.
