It also depends on how you write you Deployment Descriptor. If you specify "load-on-startup" element for a partical servlet in the DD then the servlet will be loaded as per the value that is assigned to this element.
In case if this element is missing in the web.xml then loading of Servlet will be determined by the container. It can happen at the time of container startup or can be delayed until the container determines the servlet is needed to service a request. This implimentaion varies from one container to the other.

Do you by any chance know whether such details can be part of the exam?
