16. Which of the following sources can be used to find operations for an interface?

Domain experts
Extended operations
Testability operations
All of the above
"b" and "c" only
None of the above

The answer is given as "all the above". How can Domain expert influence the interface details?

A Domain expert would be the Business User (or the representative Business Analyst )who is needed to help define use cases .
I think this activity also leads to designing interfaces as in user interfaces (GUIs) and the Business Model layer. Which one did you mean, BTW ?
I suppose you mean the UML interface, if it's a UML question.In which case, the GUI and Business Model layers could have many interfaces defined as the Use Case is written.
These questions are great, Jaydev. I am only attempting to answer , so my answer may be wrong. I am sure someone will come along and put it right.

I guess the question meant UML interfaces for classes identified from the use cases.
