Hi guys,
The book Sun Certified Enterprise Architect for J2EE Study Guide has
got this question on the Self Test section, but it suggests the
letter D as the right anwser (and it is). But why, A and E are not
correct. I guess extensibility and manageability are non-functional
requirements. What you guys think about it?
2. Which of the following are non-functional requirements?
A. Scalability, availability, extensibility, manageability, and
security
B. Performance, reliability, elaboration, transition, documentation,
and security
C. Specification, elaboration, construction, transition, use cases,
and security
D. Performance, availability, scalability, and security
E. Reliability, availability, scalability, manageability, and security

Hi,
the non functional reqs are performance, scalability, reliability, availability, manageability, extensibiliy, maintainability and security. So you're right: A,D,E are the correct answers.
 
These are the worst of times and these are the best of times. And this is the best tiny ad:
