1. Which of the following lowers maintainability [Choose 2]
A. data sharing
B. object reuse
C. code factoring
D. tight coupling
my guess is A and D. If so why A is true?.
BTW, I'd like to know more about Code Factoring and its impact on the architecture.
2. Does server clusters perform load balancing and how?
3. What is load distribution?. Is it different from load balancing?. Is this used in J2EE implementations?
4. What Firewall feature may interfere with IIOP?
5. Is passivation of Stateful session bean a CMP feature?.
6. Where can I find some useful notes on Common Architectures and Protocols?.
7. Also looking for some notes/links on pros/cons of 1-tier, 2-tier, 3-tier & n-tier architecture w.r.t scalability, maintainability, etc
Appreciate your help in sharing your ideas and providing some useful links on the above topics.
thanks

Can somebody answer these questions. Your help very much appreciated.

Hard to say... D definitely is correct... wonder how A will be correct...
What exactly is meant by Code Factoring ?

[Sridhar Raman]

A and D..
Data sharing and object reuse actually improve maintenability.. Data sharing prevents redundancy of data and formation of pools of stand alone data. Object reuse ensures reuse of existing components, which means less code written, which also means you don't have many components that do the same job....
