As an architect, you are interested in the architecture characteristics of a system. Which two are architectural characteristics?
(Choose two)
A) Scalability
B) Reliability
C) Inheritance
D) Performance

Hello, What can be the answer???
A B D are probable candidates.......but have to go for 2 only.


***** Does it require some article to be read other than service level requirements?....how are SLR's different than Arch Chara's???

Amol,

According to Sun: Quotes from SL-425 course: Architecting and Designing J2EE� Applications:
"Architecture provides high-level planning for software component location and communication to ensure the following:
� Robustness
� Performance
� Scalability"
so correct answers are A and D

Hope this helps

Robustness is an aspect of reliability which brings (B) back into play. So in still looks like A,B,D - and a junk question.

Hi Akar Rafidj,

Yeah you are right. The exam answer matchs with that too.
Is there any consolidated doc to refer for this?

Amol,

Sorry,but i don't agree with what i have posted myself! Definition of concepts are different between architects....Yes, architects are concerned with performance and scalability but also with predicability, consistency and stability which are all aspects of reliability !
I'll recommand to study "Designing Enterprise Applications with Java J2EE second edition", (J2EE blueprints) this's a useful PDF for SCEA part i, II and III.(free download from sun website).
