You are designing the deployment strategy for an ASP.NET Web application.
You need to recommend an approach for displaying a maintenance notice to users while deploying a new version of the Web application.
What should you recommend?
A.
Place a file named app_offline.htm in the root of the Web application folder.
B.
Place a file named app_offline.aspx in the root of the Web application folder.
C.
In the Web.config file, under the system.web/httpModules element, add a clear element.
D.
In the Web.config file, under the system.web/httpRuntime element, set the enable attribute to false.
Explanation:
While the App_offline.htm file exists, any requests to the Web site are redirected to this file. The file displays a friendly message that tells clients that the Web site is being updated
