How do I configure the configuration file? | JSF Interview Questions

The configuration file used is our old web.xml, if we use some IDE it will be pretty simple to generate but the contents will be something like below:
<?xml version=&uote;1.0&uote; encoding=&uote;UTF-8&uote;?>
<web-app version=&uote;2.4&uote; xmlns=&uote;http://java.sun.com/xml/ns/j2ee&uote;
xmlns:xsi=&uote;http://www.w3.org/2001/XMLSchema-instance&uote;
xsi:schemaLocation=&uote;http://java.sun.com/xml/ns/j2ee http://java.sun.<context-param>
<param-name>com.sun.faces.verifyObjects</param-name>
<param-value>false</param-value>
</context-param>
<context-param>
<param-name>com.sun.faces.validateXml</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>
</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>
index.jsp
</welcome-file>
</welcome-file-list>
</web-app>The uniue thing about this file is ?servlet mapping?. JSF pages are processed by a servlet known to be part of JSF implementation code. In the example above, it has extension of .faces. It would be wrong to point your browser tohttp://localhost:8080/MyJSF/login.jsp, but it has to be http://localhost:8080/MyJSF/login.faces. If you want that your pages to be
with .jsf, it can be done with small modification ,
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
<servlet-mapping>
