Question 1

Choose the correct answer

What can be included in a model library?

Aany model element

Bany model element that Is contained In a profile

Cany model element that can be contained in a package

Donly those model elements that are re-used in the model

Answer : C

Any model element that can be contained in a package can be included in a model library. A model library is a package with the stereotype <<modelLibrary>> applied to it. It contains reusable model elements that can be imported into other models by using an import relationship. Any kind of model element that can be owned by or nested within a package can be part of a model library, such as blocks, constraints, values, units, etc. Reference: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://www.omg.org/spec/SysML/1.6/PDF

Question 2

Choose the correct answer

What are views and viewpoints used to show?

Athe system under development by the stakeholders

Bthe modeling responsibilities of different stakeholders

Cthe aspects of a model that relate to different stakeholders

Dthe aspects of a model important to users as stakeholders

Answer : C

Views and viewpoints are used to show the aspects of a model that relate to different stakeholders. A view is a representation of a subset of a model that addresses a set of stakeholder concerns. A viewpoint is a specification of a perspective on a model that defines how a view should be constructed and used. By using views and viewpoints, different aspects of a model can be presented in a way that is relevant and understandable for different stakeholders.

Question 3

Choose the correct answer

What happens to the elements of a model when a profile is applied to the model?

AThe stereotypes defined in the profile are applied to the model's metamodel elements

BThe stereotypes defined in the profile are available to be applied to any element in the model.

CThe stereotypes defined in the profile may be applied to elements sharing compatible metaclasses

DThe stereotypes defined in the profile ate automatically applied lo the elements sharing compatible metaclasses

Answer : C

A profile is a mechanism for extending the UML or SysML metamodel with domain-specific concepts. A profile defines stereotypes, which are extensions of existing metaclasses. A metaclass is a modeling construct that defines the properties and behavior of a set of model elements. For example, the metaclass Class defines the properties and behavior of all classes in a model. When a profile is applied to a model, the stereotypes defined in the profile may be applied to elements sharing compatible metaclasses. For example, if a profile defines a stereotype <<device>> as an extension of the metaclass Class, then the stereotype <<device>> may be applied to any class in the model.

Question 4

Choose the correct answer.

What is a best practice to link actions of an activity in a SysML model to a software application described in a UML model?

AThe actions are moved into the namespace of the UML model

BThe actions are copied into the UML model using the copy relationship.

CThe actions are assigned to an activity partition that represents the software application

DThe actions in the SysML model are called by appropriate CallBehaviorActions in the UML model

Answer : D

The best practice to link actions of an activity in a SysML model to a software application described in a UML model is to use CallBehaviorActions in the UML model that call the actions in the SysML model. A CallBehaviorAction is an action that invokes a behavior and provides inputs and outputs. By using CallBehaviorActions, the software application can reuse the behavior defined in the SysML model without having to duplicate or copy it. This also ensures consistency and traceability between the models.

Question 5

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 6

Choose the correct answer

Which data exchange mechanism uses an application programming interface (API) to access data m one tool and make it available in another tool?

Amanual exchange

Bfile-based exchange

Cinteraction-based exchange

Drepository-based exchange

Answer : C

Interaction-based exchange is a data exchange mechanism that uses an application programming interface (API) to access data in one tool and make it available in another tool. The API allows for direct communication and synchronization between the tools without requiring intermediate files or repositories.This approach can provide better performance and consistency than file-based or repository-based exchange.

Question 7

Choose the correct answer

What information is required to define a viewpoint in SysML in addition to stakeholders?

Aaffects, methods, process purpose

Bconcerns, languages, methods, purpose

Cconcerns languages, tools, purpose

Dmethods, languages, rationale, responsibilities

Answer : B

The information that is required to define a viewpoint in SysML in addition to stakeholders is concerns, languages, methods, and purpose. Concerns are aspects of interest about a system that are addressed by a viewpoint. Languages are notations or modeling techniques used by a viewpoint to represent a view. Methods are processes or guidelines for constructing or interpreting views that conform to a viewpoint. Purpose is an explanation of why and how a viewpoint addresses stakeholder concerns.
