Hello Arivarasu,
Before taking up this exam, one has to be very confident on mainly four subjects,
1)RMI
2)JDBC
3)Netwroking and
4)Security in Java2 platform.
This is so because the assignment tests u mainly on these concepts.Once you are confident about these things then i think
you can go ahead with the exam.
Hope this helps,
Regards,
