How ate use cases and requirements used for requirements analysis in SysML?

A. in a SysML model, either use cases or requirements are modeled, but never both

B. Use cases are a relic from UML and are. strictly speaking, useless in a SysML model

C. Use cases are good for capturing functional requirements. For nonfunctional requirements, the requirement element is needed

D. Use cases are the basis for all requirements in a model. Requirements refine the use cases by adding additional information through then properties.

Choose the correct answer.

A system engineer specializing in rigid body dynamics wants to model the laws of motion (LOM) so that they may be reused to analyze different types of systems. The LOM consist of the mathematical relations R1 and R2. shown here.

(R1)s=ut + (1/2)at2

(R2) v = u + at

How should the system engineer represent and relate LOM. R1, and R2 in SysML?

A. Create a block for each of LOM. R1 and R? Then create part properties in LOM that are typed by R1 and R?

B. Create an activity for each of LOM. R1, and R2. Then, create actions in LOM that are typed by R1 and R2.

C. Create a constraint block for each of LOM. R1. and R2 Then, create part properties in LOM that are typed by R1 and R2.

D. Create a constraint block for each of LOM. R1, and R2- Then, create constraint properties m LOM that are typed by R1 and R2.

Choose the correct answer. Given the following diagram:

What is element C?

A. a tag value

B. an association block

C. a connector property

D. a connector illustration

E. a relation information element

Choose the correct answer.

Given the following diagram: What is the order of Interactions?

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.

Choose the correct answer. Given the following diagram:

What Is the meaning of the consider fragment?

A. It is a constraint that prevents adding a nested ignore fragment for any one of ml. m2 or m3.

B. It ignores all messages other than ml m2 and m3 in the scenario being described by the interaction

C. The meaning is undefined because the diagram is ill-formed in the absence of n>3. which must be considered.

D. It allows the invocation of the operations corresponding to messages m 1. m? and m3 only when they appear in that order

Choose the correct answer

In a state machine which behavior can be interrupted by a transition which leaves the current state?

A. a do behavior

B. an entry behavior

C. an exit behavior

D. the effect of an internal transition

Choose the correct answer.

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?

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

Which SysML construct is used to represent a connection point to an interaction when It is being used by another interaction?

A. a formal gate

B. a usage point

C. a message port

D. an interaction parameter

Choose the correct answer

Which statement is true about the read only keyword when it appears next to a property?

A. It states that the corresponding property is provided for reading purposes only

B. It specifies that the corresponding property cannot be redefined

C. It specifies that the value of the corresponding property cannot change during the lifetime of its owner.

D. It specifies that the value of the corresponding property can be changed by its owner, but can only be read by other blocks

Choose the correct answer. Given the following model:

Which statement is true?

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.
