A. Scalability, availability, extensibility, managrability, security
B. Performance, reliability, elaboration, transition, documentation and security
C. Specification, elaboration, construction, transition, use case, and security.
D. Performance, availability, scalability, and security.
E. Reliability, availability, sacalibity, manageability, and security.
=====================================================================
According to me the answer is D, Because Performance,availability, scalability, and security are architectural requirements. All the other
options are some how related to functional requirements.

Yeah, Ray..I missed A.

[Ramon Gill]

These are my thoughts on Q4 & Q5.

Q4. A and possibly B (If many people receive the sales forecasts).
Q5. A Because you don't have to wait for a response.
B Because you can have multiple MDB's feeding off one queue (i.e.
pooling).
D Scalable because of B above. You can increase the size of the
pool.

According to me the following would be the answers :
1 : E
2 : C
3 : D
4 : A,B,C
5 : C
6 : B,D

Bobby,
I disagree with some of your answers for Q4 & Q5. You included 'C' in your answers to Q4. I discounted this as there is only one receiver of the message (the stock floor), so is not publish/subscribe. For Q5, 'C' is an advantage of 'synchronous', not 'asynchronous'.
