Question 1

Choose the correct answer.

How does the quality of models relate to the quality of the modeling language used to express them?

AModel quality benefits from the degree of syntactical and semantic formalism supported by the modeling language

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

CThe level of comprehensibility of the modeling language's abstract syntax directly corresponds to the quality of the models

DThe 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

Answer : B

Question 2

Choose the correct answer

What does a model library add to a SysML model?

Astereotypes

Bcommon concepts

Cdomain-specific modeling concepts

Dmethodology-specific modeling concepts

Answer : B

A model library is a package that contains reusable model elements that can be imported into other models. A model library can add common concepts to a SysML model, such as units, quantities, value types, etc. These concepts can be used to define properties and parameters of blocks and constraints in a consistent and standardized way.

Question 3

Choose the correct answer

A senior engineer has been assigned to set up a SysML model for the development of a medical device. Many stakeholders are involved, ranging from the development team to management, quality assurance, and regulatory experts. All must use the model

Which choice defines a set of common tasks that will prepare the model for the stakeholders?

A1) Define and apply appropriate profiles
2) Create a package structure that covers the relevant aspects
3) Set up a modeling center of excellence who builds the model for the stakeholders.

BDefine and apply appropriate profiles
2) Define viewpoints for the different stakeholder concerns and set up conformant views
3) Create a package structure that covers the relevant aspects

C1) Define one common set of SysML elements for all stakeholders.
2) Create a package structure that covers the relevant aspects
3) Set up model access rights (readVwrite/delete) for the different stakeholder groups

D1) Define viewpoints for the different stakeholder concerns and set up conformant views
2) Set up model access rights (read/write/delete) for the different stakeholder groups
3) Nominate a model builder for each stakeholder group.

Answer : B

This choice defines a set of common tasks that will prepare the model for the stakeholders by using profiles, viewpoints, and packages. Profiles are used to extend SysML with domain-specific or methodology-specific concepts. Viewpoints are used to define different perspectives on the model that address different stakeholder concerns. Packages are used to organize the model elements into logical groups. These tasks will help to customize, structure, and communicate the model effectively.

Question 4

Choose the correct answer.

When defining a stereotype, a modeler may wish to put some constraints on the stereotype, its properties, or its relationships. What is the most suitable language to accomplish this?

ADSL

BOCL

CVSL

DXMI

EXML

Answer : B

OCL stands for Object Constraint Language, which is a standard language for expressing constraints on UML and SysML models. Constraints are used to specify additional rules or conditions that are not directly captured by the modeling elements or their relationships. OCL can be used to define constraints on stereotypes, their properties, or their relationships in a profile.

Question 5

Which SysML diagram type is a modification of the UML Class diagram?

AParametric Diagram

BInternal Block Diagram

CPackage Diagram

DBlock Definition Diagram

Answer : D

The SysML diagram type that is a modification of the UML Class diagram is the Block Definition Diagram (BDD). A BDD shows the definition of blocks in terms of their features, such as properties, operations, ports, etc. It is similar to a UML Class diagram, but it adds some features specific to SysML, such as value types, units, flow properties, etc. A block is an extension of the UML Class metaclass that can be used to model any system component with structure and behavior.

Question 6

Choose the correct answer-.

Which technique allows a user to objectively determine the best means of implementing a particular (unction?

Aa trade study

Ban objective analysis

Coperational research

Da requirements analysts

Answer : A

A trade study is a method for making a decision between competing alternatives based on a set of criteria, such as cost, performance, reliability, etc. A trade study allows a user to objectively determine the best means of implementing a particular function by evaluating and comparing the pros and cons of each alternative.A trade study can also help identify trade-offs and risks associated with each alternative

Question 7

Choose the correct answer

Which SysML diagram type is a modification of the UML Composite Structure diagram?

AParametric Diagram

BInternal Block Diagram

CPackage Diagram

DBlock Definition Diagram

Answer : B

The SysML diagram type that is a modification of the UML Composite Structure diagram is the Internal Block Diagram (IBD). An IBD shows the internal structure of a block in terms of its parts, ports, connectors, and flows. It is similar to a UML Composite Structure diagram, but it adds some features specific to SysML, such as flow ports, flow specifications, item flows, nested connectors, etc. Reference: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://sysml.org/tutorials/sysml-diagram-tutorial/
