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

Given the following bdd fragment and table showing messages sent between blocks:Block C Is encapsulated; none of the other blocks are.Which Ibd for block A has the correct assignment of flow ports and connectors? If two or more options are correct, select the one with the fewest ports.

Options :

A :

B :

C :

D :

Answer: B

Question 3

Given a system for keeping birds away from airports One component, described by the following diagram directs audio signals at birds that approach a runway, its parts, as part properties, are typed by blocks.

A systems engineer has identified some blacks that type the pan properties, but as the design becomes more specific, the engineer discovers that these blocks exist in multiple variants.

What modeling choice does the engineer face at this point?

Options :

A : whether to model part properties as (a) a library, or (b) a logical hierarchy

B : whether to model part properties as (a) a library or (b) a hierarchy of non-composite relationships

C : whether to model variants of blocks that type part properties as (a) explicit subclasses of the blocks, or (b) part-specific types.

D : whether to model variants of blocks that type part properties as (a) implicit subclasses of the blocks, or (b) part-specific types

Answer: A

Question 4

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 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.
