just gave a mock test. Got these 4 questions wrong, can you folks explain.
->Is Object Distribution a service provided by the ejb-container ? How is it so. (this was amongst the other options like transaction, security, persistence, pooling etc) .
->Do ejb clusters provide, caching capabilities ? I chose all the others except this one.
->which design patterns are to be used when you want to ensure that only legal combinations are to be used ?
->why is that vertical scalability has little or no impact on the reliability and scalability of the system? Definitely it does contribute to the system being more available (ofcourse not as much as horizontal scalibility would do. But it does.
