Question #10

Choose the correct answer
A system engineer is designing an algorithm that governs the behavior of his system-of-interest He is using SysML for modeling system behavior and related allocations, and plans to auto-generate MATLAB code for algorithm execution and testing.
Which modeling approach should the engineer use?

A. use activity constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm

B. use block constructs to represent the algorithm, and create use cases for each of the functions used in the algorithm

C. Code generation is outside the scope of SysML. so the system engineer should use UML

D. use package constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm

E. use block constructs to represent the algorithm and its functions, and create part properties to represent the use of the functions in the algorithm

F. use activity constructs to represent the algorithm and its functions, and create actions to represent the use of functions in the algorithm

Question #12

Choose the correct answer.
What is a common rationale for defining and applying a profile to a SysML model?

A. The profile makes the model suitable for a modeling tool

B. The profile adds appropriate metainformation to the model to allow automated system analysis

C. The profile enables separate views of the model for the different stakeholder concerns.

D. The profile extends the model with reusable elements, e.g. units.

Question #14

Choose the correct answer
What are some general rules to be applied at the end of requirements analysis to determine that (1) an activity diagram is self-consistent and (2) all elements on the diagram belong there' Select the option that gives the most general answer without including any irrelevant rules

A. Every diagram element is traceable to a requirement, use case or undocumented user need. (2) Every input object can be traced through the diagram to (a) an output object, buffer, data store or the object is consumed without producing any other object (3) .There is a path from the initial node to every activity final and How final node.(b) an action that clearly states how

B. Every diagram element is traceable to a requirement or use case (2) Every input object can be traced through the diagram to (a) an output object, buffer or data store how the object is consumed without producing any other object. (3) There is a path from the initial node to every activity final and flow final node (4) The diagram has no cycles of control flows or (b) an action that clearly states

Question #15

Choose the correct answer.
How does the quality of models relate to the quality of the modeling language used to express them?

A. The modeling language must be applicable to a wide range of domains of practice in order to produce high-quality models.

B. The quality of the modeling language does not influence tin.- quality of the models because the quality of the models depends on the skill and knowledge of the modeler

C. Model quality benefits from the degree of syntactical and semantic formalism supported by the modeling language

D. The level of comprehensibility of the modeling language's abstract syntax directly corresponds to the quality of the models

Question #16

Choose the correct answer.
Given the following diagram:

Assume that all stereotypes required by the SysML-Modehca Transformation specification (if any) have been applied but are not necessarily shown here Assume that FixedWall. ViscoelasticSpring. and RigidMass are fully defined in a Modelica library.
What else must be done to get this model ready for solving according to the SysML-Modelica Transformation specification?

A. Nothing - it is ready as-is

B. Modelica cannot handle this type of nonlinear model

C. Provide specific values Nothing else is required, as Kirchhoff's I laws are automatically taken care of consistent with the above ibd

D. Provide specific values. Also define a parametric diagram that includes equations for Kirchhoffs Laws consistent with the above ibd.

Question #18

Choose the correct answer
Modehca solvers can produce large volumes of time-based results (such as time-based power usage), but requirements are often based on scalar values such as "maximum peak power" and 'average power usage".
Which of the following is generally the most effective way to verify such requirements?

A. Modelica models can only produce time-based results and thus cannot support scalar results like these, which must either be calculated using a different tool or measured on physical prototypes Then enter the resulting scalar values into SysML, and compare them to the requirements

B. Use the SysML4Modelica profile to transform the Modelica time-based power usage results into these scalar values Then import the resulting scalar values into SysML, and compare them to the requirements.

C. ave the Modelica solver also compute these scalar values from its time-based power usage results Then import the resulting scalar values into SysML. and compare them to the requirements.

D. Import the Modelica time-based power usage results into SysML Then use SysML parametncs to calculate these scalar values, and compare them to the requirements
