Question 1

Choose the correct answer.

Consider the following two activity diagram fragments labeled Fragment 1 and Fragment 2. The JoinSpecification for Fragment 1 is completely specified, but the JoinSpecification for Fragment 2 is not.

Which join specification for Fragment 2 will make it exhibit the same behavior as fragment 1? Assume that activities with the same names exhibit the same behavior

Options :

A : b1 or b2 or b3 or b4

B : (b1 or b?) and (b3 or b4)

C : (b1 or b2) and b3 and b4

D : The question cannot be answered because Activity Diagram Fragment 1 is ambiguous

Answer: C

Question 2

Choose the correct answer.

Given the following diagram:

What is the order of Interactions?

Options :

A : Message a1 overtakes message m1, which is processed after receipt of a1.

B : Message a1 overtakes messages m1 and m2 and is processed before them.

C : Message m1 overtakes message a1, which is processed after receipt of m2.

D : Message m1 overtakes messages a1 and m2 and is processed before them.

Answer: B

Question 3

Given the following model:

Which statement is true?

Options :

A : Only Instances X1 and X? are invalid

B : Only instances X2 and X4 are invalid.

C : Only instance X4 is invalid.

D : All instances (X1, X2, X3, and X4) are valid.

Answer: C

Question 4

Given the following diagram:

How does state machine Example behave after receipt of event M1 with x equal to zero?

Options :

A : It remains in State 1.

B : it arbitrarily enters either State 2 or State 3.

C : It terminates

D : Its behavior is not defined.

Answer: A

Question 5

What is the significance of the verify relationship?

Options :

A : The verify relationship is restricted to relating a requirement to a testCase only.

B : The verify relationship extends the refine relationship to specify how the requirement will be verified.

C : The verify relationship is an extension of the satisfies relationship, relating a block to a verification activity.

D : The verify relationship relates a requirement to some other model element such as a testCase. activity, or interaction that can prove the requirement has been satisfied.

E :

The verify relationship is used to prove. That the assertion of the satisfy relationship is true Thus, a verify relationship is meaningless

without a corresponding satisfy relationship.

Answer: B
