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 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 3

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 4

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.

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 5

What are streaming parameters?

Options :

A : parameters that are mapped to flow ports

B : parameters in which tokens are never buffered

C : parameters through which a continuous stream of tokens pass

D : parameters through which an activity can accept or produce tokens throughout its execution

Answer: B
