Hi Guys,
I have started preparation for SCEA PArt I.
Objective for Commom Architecture is not clear.
Can some 1 explain tht objective in detail?
Secondly, I have found out John's notes.
Great work John !!!
But is this sufficient....as there are 6 questions on Common Architecture.And most of the guys who have appeared for exam have missed out 1 question in this objective !!!
Thanx
Sandeep

No disrespect to John, but he only scored 2 correct in 6 on common architecture.

The actual exam objective states:
Given an architecture described in terms of network layout, list benefits and potential weaknesses associated with it.

Based on this description you could spend anywhere from two days to 20 years studying. Personally I felt I had enough experience in the area to go on. I did get one question on this objective wrong though. Like some of the exam questions, I think Sun purposefully makes the objectives vague.
Basically you need a decent grasp of Networking and System Architecture. This objective goes hand in hand with the Protocol objective.

If there're something wrong or something lacking in John's notes regarding the Common Architecture, please point it out so that all of us can be benefitted.

I searched the yahoo group for a few hours and found the following URL
Sun CodeCamp
I have only had time to scan chapter one. It looks interesting. This is based on not knowing what common architecture really is.
Sandeep - They are mostly correct around here about Sun's SCEA Study Guide. The only chapter that looks hard to duplicate with web resources is the one that might be on common architectures.
The book gives some definitions on performance, scalability, manageability, reliability, security, extensibility an availability.
If you can find definitions for these in terms of quality of service then you don't need the book.
One other point the book makes, which is incorrectly published on the web, is about the use of RMI. On the web they often indicate RMI/JRMP is for Java-to-Java Systems. The book points out that you can wrap another language with a JNI proxy.
