Hi Bahadar Khan,
Check out these specific words in a question.
Front Controller:
"Workflow" and "dispatch requests to the appropriate
JSP pages" are typical uses of Front Controller.
MVC:
"Separation of data presentation and data representation"
"Provide services to different clients: web client, WAP client, etc."
"Multiple views , such as HTML or WML"
"Single Controller"
Hope these will work out. Good luck for your exam and do post your results and preparation experience.
cheers,
Sudhakar.
