NEW QUESTION # 44
Choose the correct answer
The lead systems engineer on a project has identified a set of Key Performance Parameters (KPPs) that need to be evaluated both on a periodic basis during development, and during acceptance for everydesign change.
Many of these KPPs are expressed In complex, interrelated differential equations The analysis team has identified appropriate numerical techniques for solving these equations and expressed them in a popular analysis tool.
The lead system modeler and methodologist must ensure that the architecture and design captured in the SysML system model are continuously and accurately reflected In the KPP calculations.
Which strategy is likely to be most successful in accomplishing this?
- A. List the parameters used to evaluate the KPPs in a spreadsheet file. Use the SysML modeling tool's inherent capability to link appropriate value properties to cells in this spreadsheet Task the analysis team with modifying their analysis routines to accept parameters as an input vector from this spreadsheet.
Ensure that the spreadsheet is updated from the system model prior to each update of the KPP calculations - B. Work with the analysis team to partition the KPP evaluation model into manageable, reusable subroutines Develop constraint blocks within the SysML model to represent these subroutines, exposing their parameters. Use these new constraint blocks to build a parametric model that ties the KPP evaluation directly to system model element value properties. Leverage available bridging software to link this parametric model to the evaluation subroutines executing in the external analysis tool, and re-evaluate the KPPs on an as-needed basis
- C. Task the analysis learn with recasting each of the KPP equations as constraint blocks and parametric models directly in SysML and linking the resulting parameters to value properties of current system model elements Keeping all information in the same model is the only way to guarantee the consistency the lead engineer has asked for
- D. Use activity and/or state models to accurately model the flow of data to numerically solve the KPP evaluation equations Ensure that the analysis team validates these behavior models Bind each relevant value property within the system model to an activity parameter or state variable such that the KPP evaluation model accurately reflects how the KPPs are derived. Next, use code generation capability inherent in the SysML tool to generate and compile the KPP evaluation routines Recompile and run these routines as needed to update KPP estimates

A small project has chosen a widely-used SysML-based development method, and plans to tailor the method over the life of the project.
What Is(are) the most important consideration(s) for selecting a tool to support the project? \ Choose the option that gives the project the most flexibility
- A. ability to interface with other tools that support the method
- B. built-m support for the method, mechanisms for user-defined extensions to the tool
- C. built-in support for the method: vendor commitment to provide tool tailoring for the project
- D. built-in support for the method, including documentation and context-specific help
Answer: B
Explanation:
Explanation
This is the most important consideration for selecting a tool to support the project because it gives the project the most flexibility. A built-in support for the method means that the tool has features and functions that are aligned with the SysML-based development method chosen by the project. This can include documentation, context-specific help, templates, wizards, etc. A built-in support for the method can help the project to follow the method more easily and consistently. A mechanism for user-defined extensions to the tool means that the tool allows users to customize or modify the tool according to their needs and preferences. This can include adding new features, changing existing features, creating new views or reports, etc. A mechanism for user-defined extensions to the tool can help the project to tailor the method over the life of the project and adapt to changing requirements or situations.

NEW QUESTION # 46
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 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
- B. 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
- C. 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
- D. Co-locate the modeling team Trying to maintain configuration of a model across a distributed team is extremely difficult and may not succeed
Answer: B
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:

The manager wants to architect the overall system processes based on the following.
(1) Relationships among the internal processes should be clearly identifiable and managed.
(2) The core team members should be able to improve their processes simultaneously.
(3) The architecture should aid visualization and analytics
Which model organization approach would be most efficient?
- A. create a SysML model that contains only one diagram showing all the core processes and their relationships
- B. create a SysML model that contains a package for each of the core processes, a package for each of the relationships between processes, and a package for the overall consolidated process
- C. create a SysML model that contains a package for each of the core processes, and a package for the overall consolidated process and related relationships
- D. create a SysML model for each of the core processes and for each relationship between processes
- E. create a SysML model for each of the core processes, and manage relationships between processes in a spreadsheet
Answer: B
Explanation:
Explanation
This model organization approach would be most efficient because it allows the bank manager and his core team to modularize and structure their system processes using SysML packages. A package is a grouping mechanism that can contain any kind of model element, such as diagrams, blocks, activities, etc. By creating a package for each of the core processes, the team members can work on their own processes independently and concurrently. By creating a package for each of the relationships between processes, the team can identify and manage the dependencies and interactions among the processes. By creating a package for the overall consolidated process, the team can have a holistic view of the system and perform visualization and analytics using SysML diagrams and parametrics. References:

What is common practice when integrating software models into SysML system models?
- A. The software is specified with UML in the SysML system model
- B. Cross-relationships are defined between a UML software model and a SysML system model
- C. A model-to-model transformation integrates a UML software model into a SysML system model
- D. The software is specified with SysML in the SysML system model.
Answer: B
Explanation:
Explanation
The common practice when integrating software models into SysML system models is to define cross-relationships between a UML software model and a SysML system model. A cross-relationship is a dependency that indicates a link between elements in different models or domains. By using cross-relationships, one can establish traceability and consistency between the software model and the system model without having to merge or transform them. Cross-relationships can also support allocation of software components to hardware or other software components in the system model. References:

- A. It allows users to express all the views in the architecture using only SysML elements
- B. It allows users to bring SysML elements into the architecture to enhance the hand-off between Systems of Systems and Systems.
- C. There is no benefit jas SysML is not used in compliance level 1
- D. SysML elements are only used in the Systems view to enhance the hand-off process between Systems of Systems and Systems.
Answer: B
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:

NEW QUESTION # 53
Choose the correct answer
in executing a model-based systems engineering methodology, what should the first step m building the model be?
- A. Define the domain model structure
- B. Define the business or enterprise use cases.
- C. Define the initial model organization.
- D. Define the initial set of system requirements
Answer: C
Explanation:
Explanation
The first step in building the model in executing a model-based systems engineering methodology should be to define the initial model organization. The initial model organization defines the structure and scope of the model, such as the packages, views, viewpoints and frameworks that will be used to organize the model elements and diagrams. The initial model organization provides the foundation and context for the subsequent steps in building the model, such as defining the domain model structure, defining the initial set of system requirements or defining the business or enterprise use cases. The initial model organization can also help establish the modeling conventions and standards that will be followed throughout the model development process.

- A. the modeling responsibilities of different stakeholders
- B. the aspects of a model important to users as stakeholders
- C. the system under development by the stakeholders
- D. the aspects of a model that relate to different stakeholders
Answer: D
Explanation:
Explanation
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. References:

Which relationship is likely to be most heavily used during requirements analysis?
- A. satisfy
- B. verify
- C. refine
- D. copy
Answer: C
Explanation:
Explanation
The refine relationship is likely to be most heavily used during requirements analysis because it is used to indicate that a model element provides more details or information about a requirement. The refine relationship can be used to link requirements to other requirements, use cases, activities, blocks or any other model elements that can help clarify or elaborate the requirements. The refine relationship can also be used to decompose a requirement into sub-requirements or to show how a requirement is derived from another requirement. The copy relationship is used to indicate that a requirement is identical to another requirement.
The satisfy relationship is used to indicate that a design element fulfills a requirement. The verify relationship is used to indicate that a test case or procedure confirms that a design element satisfies a requirement.

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.

- C. how the system model can be used to facilitate change proposals, support plans, and training in the operational environment
- D. how field support operations can be modeled using MBSE methods
Answer: C
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.

The main diagram type in Modelica corresponds most closely to which SysML diagram type?
- A. ibd
- B. par
- C. bdd
- D. act
Answer: A
Explanation:
Explanation
The main diagram type in Modelica corresponds most closely to the ibd (internal block diagram) in SysML.
An ibd shows the internal structure of a block in terms of its parts, ports, connectors, and flows. It is similar to a Modelica diagram, which shows the components of a model in terms of their connectors and equations. Both diagram types can be used to represent physical systems composed of interconnected elements with defined behaviors and properties. References:

A project is evaluating several modeling tools which comply in vanous degrees to SysML abstract and concrete syntax The customer will allow some deviation from full compliance, as long as technical risk is minimized.
Which tool characteristics are required for this project?
- A. full compliance with both abstract and concrete syntax, nothing less is adequate
- B. limited deviations from abstract and concrete syntax
- C. full compliance with abstract syntax, and limited deviations from concrete syntax
- D. full compliance with concrete syntax, and limited deviations from abstract syntax
Answer: C
Explanation:
Explanation
This tool characteristic is required for this project because it ensures that the modeling tool follows the SysML abstract syntax, which defines the metamodel elements and their semantics. The abstract syntax is essential for ensuring consistency and interoperability between different tools and models. The concrete syntax, which defines the notation and presentation of the elements, can have some deviations as long as they do not affect the meaning or interpretation of the model. For example, a tool can use different colors or shapes for some elements without changing their semantics. References:

Which kinds of model elements ate used to populate the typical stakeholder views of a design?
- A. primarily use case and requirements diagrams
- B. primarily behavior elements, such as activity, state and sequence diagrams
- C. both behavioral and structural diagrams
- D. primarily structural elements, such as block definition and internal block diagrams
Answer: C
Explanation:
Explanation
The typical stakeholder views of a design are composed of both behavioral and structural diagrams, depending on the purpose and perspective of the view. Behavioral diagrams show how the system or part behaves or interacts in different scenarios or states, such as activity, state and sequence diagrams. Structural diagrams show how the system or part is composed of parts, ports, connectors and properties, such as block definition and internal block diagrams. Both types of diagrams are important to convey the functionality and architecture of the system or part to different stakeholders. Use case and requirements diagrams are not sufficient to populate the stakeholder views of a design, as they only capture the functional and non-functional aspects of the system or part.

What kind of models can be exchanged using XMI?
- A. instances of metamodels that can be described by an XML schema
- B. only UML models including profiles
- C. only UML and SysML models
- D. instances of MOF models
Answer: D
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:

How does the quality of models relate to the quality of the modeling language used to express them?
- A. 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
- B. The level of comprehensibility of the modeling language's abstract syntax directly corresponds to the quality of the models
- C. Model quality benefits from the degree of syntactical and semantic formalism supported by the modeling language
- D. The modeling language must be applicable to a wide range of domains of practice in order to produce high-quality models.
Answer: C
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.
