1) If the logic of authentication and authorization is common for all or a lot of servlets in a web application, then you should encapsulate the logic in a filter class. I had a question in similar context during the exam, I chose Intercepting Filter pattern and was marked correct.

2) I will say Front Controller because Strut allows developer to define a form bean to validate request parameters and then forward the request to appropriate page based on the result of the validation.

Please correct me if I am wrong.
