In a scenario-based development approach, which SysML diagram type could best be used to describe the scenarios?
- A. activity diagram
- B. state diagram
- C. requirements diagram
- D. use case diagram
Answer: D
Explanation:
Explanation
In a scenario-based development approach, use case diagram could best be used to describe the scenarios. A use case diagram shows how actors interact with use cases in different scenarios or situations. A use case diagram can capture the functional requirements and goals of a system or part from different stakeholder perspectives. A use case diagram can also show how use cases are related to each other by generalization, inclusion or extension relationships. A state diagram shows how an object changes its state in response to events or stimuli. A statediagram is not suitable for describing scenarios that involve multiple actors or use cases. An activity diagram shows how actions are performed in a sequence or in parallel by objects or flows.
An activity diagram is not suitable for describing scenarios that involve different situations or alternatives. A requirements diagram shows how requirements are specified, derived, satisfied or verified by model elements.
A requirements diagram is not suitable for describing scenarios that involve interactions or behaviors.

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. Code generation is outside the scope of SysML. so the system engineer should use UML
- B. use block constructs to represent the algorithm, and create use cases for each of the functions used in the algorithm
- C. use block constructs to represent the algorithm and its functions, and create part properties to represent the use of the functions in the algorithm
- D. use activity constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm
- E. use package constructs to represent the algorithm and its functions, and create containment relationships to represent the use of 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
Answer: F
Explanation:
Explanation
This modeling approach should be used by the system engineer because it allows him to capture the behavior of his system-of-interest using SysML activities and actions. An activity is a behavior that specifies the coordination of actions. An action is a behavior that specifies a transformation or processing of data. By using activities and actions, the engineer can model the algorithm and its functions in terms of inputs, outputs, control flows, object flows, parameters, etc. He can also use allocations to relate the activities and actions to other model elements, such as blocks or requirements. This way, he can generate MATLAB code from his SysML model for execution and testing. References:

A systems engineer's company is considering making a substantial investment In a Product Lifecycle Management (PLM) solution. As a Model Based Systems Engineering expert. The engineer has been asked to advise the team on how MBSE methodology impacts the PLM solution Which option lists the most important factors that the engineer should consider"?
- A. how well any proposed MBSE methodology interfaces with the company's Model Driven Software Development methodology, and how this is facilitated by PLM tools
- B. the high cost of maintaining modeling tools and modeling proficiency training, and potential advantages of teaming arrangements with vendors
- C. how outputs of system models, software models, and hardware models are archived in Product Data Management (PDM) tools, and how these models can be organized into libraries within these tools
- D. how manufacturing, lest and integration methods can be driven by system models, and how this is facilitated by PLM tools
- E. the spectrum of models the company uses across the system lifecycle. how model elements can be related to each other, and how these relationships are supported by PLM tools
Answer: E
Explanation:
Explanation
The most important factors that the engineer should consider when advising the team on how MBSE methodology impacts the PLM solution are the spectrum of models the company uses across the system lifecycle, how model elements can be related to each other, and how theserelationships are supported by PLM tools. The spectrum of models refers to the different types, levels and views of models that are used to represent different aspects and phases of the system development, such as requirements, design, analysis, verification and validation. The relationships between model elements refer to the traceability, consistency and dependency links that connect different elements within and across models. The support by PLM tools refers to the ability of the tools to store, manage, access and integrate the models and their relationships throughout the system lifecycle. These factors are important because they affect how well the MBSE methodology can be implemented and executed using the PLM solution. How manufacturing, test and integration methods can be driven by system models is a less important factor that may not be relevant to all systems or projects. The high cost of maintaining modeling tools and modeling proficiency training is a less important factor that may not be specific to MBSE methodology or PLM solution. How well any proposed MBSE methodology interfaces with the company's Model Driven Software Development methodology is a less important factor that may not apply to all systems or projects. How outputs of system models, software models, and hardware models are archived in Product Data Management (PDM) tools is a less important factor that may not reflect the full potential of MBSE methodology or PLM solution.

How does the quality of models relate to the quality of the modeling language used to express them?
- A. Model quality benefits from the degree of syntactical and semantic formalism supported by the modeling language
- 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. The level of comprehensibility of the modeling language's abstract syntax directly corresponds to the quality of the models
- D. The modeling language must be applicable to a wide range of domains of practice in order to produce high-quality models.
Answer: A
Explanation:
Explanation
The quality of models relates to the quality of the modeling language used to express them in that model quality benefits from the degree of syntactical and semantic formalism supported by the modeling language.
Syntactical and semantic formalism refers to the rules and meanings that define how the modeling language elements and relationships can be used and interpreted. A high degree of syntactical and semantic formalism can help improve the clarity, consistency and correctness of the models and avoid ambiguity, inconsistency and error. A high degree of syntactical and semantic formalism can also enable automated analysis, verification and validation of the models. The modeling language does not have to be applicable to a wide range of domains of practice in order to produce high-quality models, as some modeling languages may be more suitable or specialized for certain domains than others. The level of comprehensibility of the modeling language's abstract syntax does not directly correspond to the quality of the models, as abstract syntax is only one aspect of the modeling language that defines its structure and notation. The quality of the modeling language does influence the quality of the models because the quality of the models depends not only on the skill and knowledge of the modeler but also on the expressiveness and precision of the modeling language.

What are two cross-cutting mechanisms within SysML that can be used to establish traceability between the systems model and a UML software model?
- A. requirement relationships and allocations
- B. profiles and stereolypes
- C. allocations and stereotypes
- D. packages and parametrics
Answer: C
Explanation:
Explanation
Two cross-cutting mechanisms within SysML that can be used to establish traceability between the systems model and a UML software model are allocations and stereotypes. Allocations are dependencies that indicate a relationship between elements in different models or domains. Stereotypes are extensions of existing metaclasses that add additional information or semantics to model elements. By using allocations and stereotypes, different aspects of the systems model and the software model can be linked and traced.

Which statement about working in UPDM compliance level 1 is true?
- A. It allows users to express all the views in the architecture using only SysML elements
- B. SysML elements are only used in the Systems view to enhance the hand-off process between Systems of Systems and Systems.
- C. There is no benefit jas SysML is not used in compliance level 1
- D. It allows users to bring SysML elements into the architecture to enhance the hand-off between Systems of Systems and Systems.
Answer: D
Explanation:
Explanation
Working in UPDM compliance level 1 allows users to bring SysML elements into the architecture to enhance the hand-off between Systems of Systems and Systems. Compliance level 1 is based on UML and SysML concepts and provides integration with system modeling using SysML. Users can use SysML elements, such as blocks, ports, connectors, parametrics, etc., to model system components and their interactions in more detail and precision than using UML elements alone. This can facilitate the transition from architecture modeling to system design and analysis. References:

What happens to the elements of a model when a profile is applied to the model?
- A. The stereotypes defined in the profile are available to be applied to any element in the model.
- B. The stereotypes defined in the profile ate automatically applied lo the elements sharing compatible metaclasses
- C. The stereotypes defined in the profile are applied to the model's metamodel elements
- D. The stereotypes defined in the profile may be applied to elements sharing compatible metaclasses
Answer: D
Explanation:
Explanation
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 beapplied 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.

Which aspect of a MBSE-based engineering project falls outside of the scope of AP233?
- A. issue management
- B. diagrams
- C. lifecycle stages
- D. slate machines
Answer: B
Explanation:
Explanation
This aspect of a MBSE-based engineering project falls outside of the scope of AP233 because AP233 does not cover diagrams. AP233 (Application Protocol 233) is a standard that defines an information model for systems engineering. It specifies the concepts and relationships for representing systems engineering data, such as requirements, functions, properties, etc. AP233 does not define any notation or presentation for diagrams, such as SysML diagrams. AP233 only defines the serialization and deserialization of systems engineering data using XMI (XML Metadata Interchange) format. Therefore, AP233 does not address how to exchange diagrams between tools or how to visualize diagrams in different tools. References:

A system modeler exports requirements from a requirements management tool into a spreadsheet and then imports the requirements into a system modeling tool.
Which type of data exchange is this considered?
- A. interaction-based exchange
- B. manual exchange
- C. repository-based exchange
- D. file-based exchange
Answer: D
Explanation:
Explanation
This type of data exchange is considered file-based exchange because it involves transferring data between different tools using files as intermediaries. A file-based exchange is a common way of exchanging data between tools that do not have direct integration or compatibility. It requires the tools to support import and export functions for a common file format, such as CSV, XML, XMI, etc. A file-based exchange can be useful for transferring large amounts of data or for performing batch operations. However, it can also have some drawbacks, such as loss of information, lack of synchronization, or manual intervention. References:

Which data exchange mechanism uses a database that is accessible by two or more tools m order to share data?
- A. file-based exchange
- B. interaction-based exchange
- C. manual exchange
- D. repository-based exchange
Answer: D
Explanation:
Explanation
This type of data exchange mechanism uses a database that is accessible by two or more tools in order to share data. A repository-based exchange is a way of exchanging data between tools that have direct integration or compatibility. It requires the tools to access a common database that stores the data in a standardized format, such as XMI, AP233, etc. A repository-based exchange can be useful for transferring data in real-time or for performing collaborative operations. However, it can also have some drawbacks, such as security, scalability, orperformance issues. References:

What is the best way to ensure that a shared model has consistently-represented elements and diagrams?
- A. Implementation of standard libraries
- B. domain stereotypes maintained in a configuration control system
- C. modeling conventions and standards
- D. packages that map one-for-one to components
Answer: C
Explanation:
Explanation
The best way to ensure that a shared model has consistently-represented elements and diagrams is to use modeling conventions and standards. Modeling conventions and standards are rules and guidelines that define how the model elements and diagrams should be named, defined, structured, formatted and documented.
Modeling conventions and standards can help improve the clarity, consistency and quality of the model and facilitate the communication and collaboration among the modelers and stakeholders. Implementation of standard libraries is a good way to ensure that a shared model has reusable and interoperable elements and diagrams, but it may not ensure their consistent representation. Packages that map one-for-one to components is a good way to ensure that a shared model has modular and traceableelements and diagrams, but it may not ensure their consistent representation. Domain stereotypes maintained in a configuration control system is a good way to ensure that a shared model has customized and controlled elements and diagrams, but it may not ensure their consistent representation.

What characterizes a complete SysML model?
- A. It includes a complete set of SysML constructs and associations for the system being modeled
- B. It uses all SysML diagram types to model all aspects of the system or part being modeled.
- C. All of its element trace back to requirements that are within the scope of the project
- D. It has all the necessary information relevant at the level of abstraction that the model represents.
Answer: D
Explanation:
Explanation
A complete SysML model is one that has all the necessary information relevant at the level of abstraction that the model represents. A complete model does not necessarily have to trace back to all requirements, use all diagram types, or include all constructs and associations. A complete model should capture the essential features and properties of the system or part being modeled, without being too detailed or too abstract. A complete model should also be consistent, coherent and correct. References: OMG-Certified Systems Modeling Professional - Model Builder - Advanced (OCUP2-ADV) Examination Guide Version 1.0, Section
