Good job ian.. I have couple of questions though.. You need to integrate your application with a mainframe system but don't have any access to the mainframes code. What is the best technique for this? (A) It can't be done. (B) Use a screen scraper. (C) Re-write the main frame using Java. (D) Write a Java front end then use CORBA to communicate with the mainframe Ans: (B) ... why not (D)?
What are the weaknesses of two-tier architecture with regards to the following areas? (A) Fat Clients (B) Thin Clients (C) Scalability (D) Potential Network bottlenecks Tightly coupled/brittle architecture has main weakness like Fatclient(mix of presentation and business logic) and scalability issues. But i dont see network bottlenecks. Can any one explain it to me how (D)is also a valid anwer? -Ragu SCJP2 [ April 13, 2002: Message edited by: Ragu Sivaraman ]
