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. file-based exchange
- C. repository-based exchange
- D. manual exchange
Answer: B
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:

What can be included in a model library?
- A. only those model elements that are re-used in the model
- B. any model element that can be contained in a package
- C. any model element that Is contained In a profile
- D. any model element
Answer: B
Explanation:
Explanation
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.

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. 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.
- B. 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
- C. 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.
- D. 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
Answer: A
Explanation:
Explanation
The most effective way to verify such requirements is to have 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. This way, the verification can be done at the same level of abstraction as the requirements, and avoid unnecessary transformations or calculations in SysML. Modelica solvers can provide various functions and operators to compute scalar values from time-based results, such as max, min, mean, integral, etc. References:

How should stereotypes be grouped to facilitate re-use in later projects?
- A. in metamodels
- B. in profiles
- C. in packages
- D. in sub-models
Answer: B
Explanation:
Explanation
Stereotypes should be grouped in profiles to facilitate re-use in later projects. A profile is a mechanism for extending UML or SysML with additional modeling elements that are not part of the standard language. A profile defines stereotypes, which are extensions of existing metaclasses. A profile can be applied to a model to make the stereotypes available for use. Bygrouping stereotypes in profiles, they can be easily reused in different models or projects. References:

What kind of models can be exchanged using XMI?
- A. only UML models including profiles
- B. instances of metamodels that can be described by an XML schema
- C. instances of MOF models
- D. only UML and SysML models
Answer: C
Explanation:
Explanation
The kind of models that can be exchanged using XMI are instances of MOF models. MOF (Meta-Object Facility) is a standard that defines a metamodeling architecture and a set of metamodels for creating and manipulating models. A metamodel is a model that defines the abstract syntax and semantics of another model. A model is an instance of a metamodel that conforms to its rules and constraints. XMI (XML Metadata Interchange) is a format specification that enables the interchange of objects and models through an XML formatted file. It is based on a metamodel that defines the mapping of MOF concepts to XML concepts. By using XMI, any model that is an instance of a MOF metamodel can be serialized and deserialized in terms of XML elements and attributes. This includes UML, SysML, and other modeling languages that are defined as MOF metamodels. References:

- C. how software design patterns can be used to suggest Pre Planned Product Improvement (P3I) opportunities
- D. how field support operations can be modeled using MBSE methods
Answer: A
Explanation:
Explanation
The most important aspect of system development methodologies that the engineer is likely to discuss with the director of field support is how the system model can be used to facilitate change proposals, support plans, and training in the operational environment. The system model can provide a consistent and comprehensive view of the system's structure, behavior and performance throughout its lifecycle, and can help identify and evaluate potential changes, improvements or issues in the field. The system model can also help document and communicate the support requirements, procedures and resources for the system's operation and maintenance.
The system model can also help design and deliver effective training programs for the system's users and operators. How field support operations can be modeled using MBSE methods, how software design patterns can be used to suggest Pre Planned Product Improvement (P3I) opportunities, and how operational evaluation (OPEVAL) plans can be developed and cross-checked in a system modeling environment are less important aspects of system development methodologies that may not be relevant or applicable to the director of field support's concerns.

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?
- A. VSL
- B. XMI
- C. OCL
- D. DSL
- E. XML
Answer: C
Explanation:
Explanation
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. References:

NEW QUESTION # 47
Choose the correct answer.
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.

- B. The activities in a typical systems engineering methodology can be performed in any order
- C. The activities in a typical systems engineering methodology are applied sequentially.
- D. The activities in u typical systems engineering methodology work just as well for specialty engineering activities
Answer: A
Explanation:
Explanation
A systems engineering methodology is a collection of related processes, methods, and tools that support the discipline of systems engineering in a specific context. The activities in a typical systems engineering methodology are applied iteratively, meaning that they are repeated and refined until a satisfactory solution is achieved. The activities are not applied sequentially, meaning that they are not performed in a fixed order without revisiting previous steps. The activities cannot be performed in any order, because they have logical dependencies and prerequisites. The activities do not work just as well for specialty engineering activities, because they may require different processes, methods, and tools

Given the following diagram fragment:
Which criterion indicates that a decision node construct such as this is well-formed?
- A. The guards are understandable by stakeholders in the development effort.
- B. Each guard legal can be evaluated without changing the state of any item referenced by the corresponding activity or action Ai
- C. Taken together, the guards cover all possibilities and are mutually exclusive.
- D. No activity Ai will negate the corresponding guard [gi]
Answer: C
Explanation:
Explanation
A decision node is a construct in SysML that represents a branching point in an activity diagram where alternative paths are chosen based on some conditions. The guards are expressions that specify the conditions for each outgoing edge from the decision node. A criterion that indicates that a decision node construct is well-formed is that the guards cover all possibilities and are mutually exclusive, meaning that for any input value, exactly one guard evaluates to true and all others evaluate to false. This ensures that there is no ambiguity or conflict in choosing the next path in the activity.

Which option is a measure of model quality?
- A. the number of actions and activities with no incoming object 01 control flows
- B. the number of blocks that have been implemented
- C. the number of textual requirements approved by the customer
- D. the estimated time to complete the use case model
Answer: A
Explanation:
Explanation
A measure of model quality is a metric that evaluates how well a model satisfies some desired characteristics, such as correctness, completeness, consistency, clarity, etc. The number of actions and activities with no incoming object or control flows is a measure of model quality that indicates how well the model captures the dependencies and sequences of events in the system. A high number of such actions and activities may imply that the model is incomplete or inconsistent, and may lead to errors or ambiguities in the system behavior.

What is the key distinction between SysML modeling and MOF modeling?
- A. MOF models are used for domain-independent modeling SysML models are used for domain-specific modeling.
- B. They both have the same purpose except that MOF modeling is intended for specialized and advanced usage by systems architects
- C. MOF models are intended to be strictly models of abstract entities SysML models represent real world entities and processes
- D. MOF models are intended to be models of modeling constructs SysML models represent real world entities and processes.
Answer: D
Explanation:
Explanation
MOF stands for Meta-Object Facility, which is a standard for defining metamodels. Metamodels are models of modeling constructs, such as classes, attributes, associations, etc. SysML stands for Systems Modeling Language, which is a standard for modeling complex systems using diagrams and textual notations. SysML models represent real world entities and processes, such as components, behaviors, requirements, etc. The key distinction between SysML modeling and MOF modeling is that SysML models are instances of a metamodel defined by MOF.

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 activity constructs to represent the algorithm and its functions, and create actions to represent the use of functions in the algorithm
- C. use package constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm
- D. Code generation is outside the scope of SysML. so the system engineer should use UML
- E. use block constructs to represent the algorithm, and create use cases for each of the functions used in the algorithm
- F. use block constructs to represent the algorithm and its functions, and create part properties to represent the use of the functions in the algorithm
Answer: B
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 system engineer designing a smart-home system is working with three analysts using specialized computational tools to evaluate energy consumption, waste production, and reliability of the system The team is soliciting a recommendation for an approach that achieves the following (1) Analysis models should Incorporate design details necessary for evaluation (2) Analysis models should be easily adaptable for different types of smart-home systems Which recommendation would be most effective from a MBSE perspective'?
- A. The system engineer should create a SysML model for capturing high-level design specifications of different types of smart-home systems, which the analysts can consult for creating and maintaining analysis models in their individual tools.
- B. The system engineer should create a SysML model loi capturing the design ol different types of smart-home systems, and the analysts should set up executable templates/scripts to generate analysis models from the SysML model
- C. The system engineer should create a SysMI model for capturing the high level design specifications of different types of smart-home systems. This SysML model should contain a package for each of the analyses and dependency relations between the design specifications and the analysis packages
- D. The system engineer should create a SysML model for capturing the design of different types of smart-home systems, and the analysts should each create a SysML model representing their specific analysis. All four SysML models should then be linked together.
Answer: B
Explanation:
Explanation
This recommendation would be most effective from a MBSE perspective because it allows the system engineer and the analysts to leverage the SysML model as a source of design information and analysis input. A SysML model is a graphical and textual representation of a system and its structure, behavior, requirements, etc. By creating a SysML model for capturing the design of different types of smart-home systems, the system engineer can specify the relevant design details necessary for evaluation, such as parameters, constraints, properties, etc. The analysts can then set up executable templates/scripts to generate analysis models from the SysML model using various methods and tools. This way, the analysts can ensure that their analysis models incorporate the latest design information and are easily adaptable for different types of smart-home systems.
The system engineer and the analysts can also use allocation or synchronization mechanisms to link the SysML model and the analysis models and propagate changes between them. References:

Choose the correct answer
A company is executing a large distributed engineering project. More than a dozen engineers are contributing to the system model, working from different locations spread across three time zones The lead engineer has decided that it is essential to maintain a single model. The department director has expressed concern that the project may have trouble employing its engineers productively while still maintaining configuration control of this common model.
Which configuration management strategy is likely to be most successful*?
- A. Use a configuration management tool to manage model elements. Allow packages to be checked out by any user for editing, which locks the elements therein contained Packages may be viewed in read-only mode by any user at any time All model users receive alerts when a package they are viewing has been modified and checked-in. and changes are highlighted Packages may not remain checked out overnight
- B. Co-locate the modeling team Trying to maintain configuration of a model across a distributed team is extremely difficult and may not succeed
- C. Use a centralized repository for the model files Allow only engineers in the eastern-most time zone to upload changes to the model files in the mornings, and the western engineers in the afternoons. Either can download and view the model files at any time. This will assure maximum productivity while minimizing the possibility of collisions
- D. Use a configuration management tool to manage model elements. Assign ownership of model elements at the package level- Only the owner of a package may make changes to elements in that package Note that each relationship between model elements must be contained within a single package
Answer: A
Explanation:
Explanation
This configuration management strategy is likely to be most successful because it allows the engineers to work on the system model collaboratively and concurrently, while maintaining configuration control and avoiding conflicts. A configuration management tool is a software tool that helps manage changes to model elements and track their versions and history. A package is a grouping mechanism that can contain any kind of model element, such as diagrams, blocks, activities, etc. By using a configuration management tool, the engineers can check out packages for editing, which locks the elements in that package and prevents other users from modifying them. The engineers can also view packages in read-only mode by any user at any time, which allows them to see the latest version of the model without affecting it. The engineers can also receive alerts when a package they are viewing has been modified and checked-in by another user, and see the changes highlighted. This way, the engineers can stay informed and synchronized with the model updates. By not allowing packages to remain checked out overnight, the engineers can avoid holding up the work of other users who need toaccess or modify those packages. References:
