24) A system undergoing performance testing is found to be "thrashing" (a condition that occurs when there is too much concurrency). Which of the following artifacts would be MOST helpful to uncover the problem?

a) The use case descriptions
b) A state diagram
c) A process view
d) An activity diagram
e) A collaboration diagram

I opt b, d ( answer c, d)
Multiple Select - Please select all of the correct answers (this question has 2 correct choices).
37) Which of the following are TRUE about the strengths and weaknesses of activity diagrams?

a) Activity diagrams are good at enumerating object collaborations to accomplish a task.
b) Activity diagrams are good at exploring the interactions related to one or more use cases.
c) It is difficult to discern exactly how to map the activity diagram actions to object model specifics.
d) Since activity diagrams allow parallel behavior modeling, they are good for workflow modeling.

I opt a, b, c (Answer b, c, d; a should be interaction diagram)
Multiple Select - Please select all of the correct answers (this question has 3 correct choices).

47) Which of the following are TRUE about interaction diagrams?

a) Interaction diagrams are at their best when they illustrate multiple scenarios.
b) Interaction diagrams are good at designing part or all of one use case's functionality across multiple objects.
c) Interaction diagrams are good for static modeling, since they fill out the classes and methods in the domain.
d) Interaction diagrams allow the analyst to show iteration and conditional execution for messaging between objects.
e) Sequence diagrams are logically equivalent to collaboration diagrams, differing primarily in format of presentation.

I opt b, c, e (answer b,d, e)
Multiple Select - Please select all of the correct answers (this question has 3 correct choices).


53) When it comes time to write code, an interaction diagram can quickly provide information on which of the following?

a) Navigability of associations
b) The sequence of method calls
c) Conditions under which a message is sent
d) State changes in an object
e) Iteration in the control flow

I opt b,c, e
Multiple Select - Please select all of the correct answers (this question has 3 correct choices).
56) During implementation, the development team decides to use a third party utility to provide some of the required functionality. What OOAD artifact would MOST likely reflect this change?

a) Activity diagram
b) Package diagram
c) State diagram
d) Interaction diagram

I opt b ( Answer d)
Single Select - Please select the best answer (one and only one choice must be selected).

24) Artifact uncover too much concurrency problem
I opt b,d too. Sunny, do you mean IBM answers c,d?
37) the strengths and weaknesses of activity diagrams?
Can you explain why you ruled out d?
47) TRUE about interaction diagrams?
I opt b,c,d,e (I think there should be 4 correct choices). Your answer and comments?
53) an interaction diagram can quickly provide what?
b,c,e
56) OOAD artifact reflect a third party utility
I opt b.
