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. profiles and stereolypes
- B. requirement relationships and allocations
- C. packages and parametrics
- D. allocations and stereotypes
Answer: D
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.

What is one of the most common reasons to utilize a SysML-Modehca integration?
- A. to solve and analyze system advanced statistics models
- B. to execute and analyze system state machine models
- C. to execute and analyze system activity models
- D. to solve and analyze system dynamics models
Answer: D
Explanation:
Explanation
One of the most common reasons to utilize a SysML-Modelica integration is to solve and analyze system dynamics models. Modelica is a language for modeling complex physical systems based on equations and components. SysML is a language for modeling complex systems based on diagrams and textual notations. By integrating SysML and Modelica, system dynamics models can be defined in SysML using parametric diagrams and constraint blocks, and then solved and analyzed using Modelica tools and solvers.

What is the most significant deficiency impeding widespread use of SysML (without MARTE) in the real-time and embedded domain?
- A. a means to distinguish embedded from non-embedded systems
- B. a means to quantify interactions between a system and its physical environment
- C. a quantifiable notion of time and resources
- D. the terminology that is shared with the RT7E domain
Answer: C
Explanation:
Explanation
The most significant deficiency impeding widespread use of SysML (without MARTE) in the real-time and embedded domain is a quantifiable notion of time and resources. SysML does not provide a standard way to model time-related properties or constraints, such as deadlines, periods, durations, clocks, etc., nor does it provide a standard way to model resource-related properties or constraints, such as memory, CPU, power, etc.
These aspects are essential for real-time and embedded systems design and analysis. MARTE addresses this deficiency by providing concepts and annotations for modeling time and resources in a precise and quantitative way. References:

What is the purpose of the Domain Metamodel in UPDM?
- A. It defines the melamodel concepts and relationships without any implementation
- B. It defines the mapping of UML to SysML and SOAML concepts
- C. It defines the stakeholder requirements for the metamodel.
- D. It defines the implementation metamodel.
Answer: A
Explanation:
Explanation
The purpose of the Domain Metamodel in UPDM is to define the metamodel concepts and relationships without any implementation. The Domain Metamodel captures the core concepts of DoDAF and MODAF in terms of entities, attributes, associations, and constraints. It does not specify how these concepts are implemented in UML, SysML, or any other language or tool. The Domain Metamodel serves as a requirements model for UPDM and provides traceability links between the domain concepts and the profile elements.

NEW QUESTION # 19
Choose the correct answer
A large company uses SysML to design energy systems, and plans to use a specialized proprietary analysis tool (X) for evaluating and comparing the cost, performance, and reliability of energy system alternatives The engineers at the company want to automatically create analysis models in X from design models in SysML.
The achieve this, they will use the following process:
(1) Specify the appropriate module in X10 be used for each block m the SysML design model.
(2) Write scripts that use these mappings to automatically create analysis models in X Which approach is most flexible when enabling this automation?
- A. define a profile that contains a stereotype for each type of module m X. and assign the stereotype to the blocks in lite design model
- B. define a package that contains a note for each type of module in X. and anchor notes to the blocks in the design model
- C. define a package that contains a block for each type of module m X (e g module_1 block) and create a dependency relationship from the module block to the blocks in the design model
- D. define a profile that contains a stereotype with a tag that can store the name of the module in X. apply the stereotype to the blocks in the design model, and populate the tag
- E. define a profile that contains a tag for each type of X in the tool, and assign the stereotype to the blocks in the design model
Answer: D
Explanation:
Explanation
A profile is a mechanism for customizing SysML for a specific domain or purpose. A stereotype is a way of extending or modifying the semantics of a SysML element. A tag is an attribute of a stereotype that can store additional information. By defining a profile that contains a stereotype with a tag that can store the name of the module in X, the engineers can easily map the blocks in the design model to the corresponding modules in X, and use scripts to automate the creation of analysis models. This approach is more flexible than using notes, dependencies, or predefined tags, because it allows for more control and consistency over the mapping proces

What is common practice when integrating software models into SysML system models?
- A. The software is specified with SysML in the SysML system model.
- B. Cross-relationships are defined between a UML software model and a SysML system model
- C. The software is specified with UML in the SysML system model
- D. A model-to-model transformation integrates a UML software model into a 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:

What is best practice to model a software application in a SysML model for a system?
- A. block stereotyped with "software" represents the software application and its interfaces
- B. A component stereotyped with "software" represents the software application and its interfaces.
- C. Software is typically not modeled in a system SysML model
- D. A class stereotyped with "software" represents the software application and its interfaces
Answer: A
Explanation:
Explanation
The best practice to model a software application in a SysML model for a system is to use a block stereotyped with "software" to represent the software application and its interfaces. A block is a modular unit that encapsulates its structure and behavior and can be connected to other blocks via ports and connectors. A stereotype is an extension of an existing metaclass that adds additional information or semantics to a model element. By using a block stereotypedwith "software", the software application can be modeled as a system component with its own properties, operations, ports, flows, etc., and can be allocated to hardware blocks or other software blocks.

NEW QUESTION # 22
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. 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
- 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. 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

Understanding OCL is important to the understanding of which item(s)?
- A. a typical high-level domain model
- B. tool-generated XMI for a SysML model
- C. software developers' modifications to a SysML model
- D. both the UML and SysML specifications
Answer: D
Explanation:
Explanation
OCL is important to the understanding of both the UML and SysML specifications because it is used to define the semantics and constraints of the modeling elements and relationships in both languages. OCL is part of the UML standard and is adopted by SysML as a complementary language. OCL can also be used to specify queries, expressions and operations on models. OCL is not directly related to a typical high-level domain model, tool-generated XMI for a SysML model, or software developers' modifications to a SysML model.

Choose the correct answer.
A team of designers led by a hardware systems engineer is finding it difficult to manage the design of a distributed air-conditioning system_ Each system component Is a complex assembly with multiple design models (such as MCAD. ECAD, and Spreadsheets). The system engineer wants to architect an approach that achieves the following (1) provides a unified view of the design of the system and Its components (2) provides a unified model for generating a bill-of-materials (3) provides sufficient semantics to propagate changes made in one design model to another Assume that the system engineer Is allocated resources to purchase or develop the new software required for this architecture Which approach would be most effective from a MBSE perspective?
- A. import each design model into a single SysML model and then create relationships between the design models
- B. create a SysML block structure representing (he system and its components, and then create relationships between the blocks and the design models
- C. import each design model into a separate SysML model, link the SysML models together, and then create relationships between the design models
- D. create a SysML activity structure representing the design process of each component, and then create relationships between the activity parameters and the design models
- E. create a SysML package structure representing the system and its components, and then create relationships between the packages and the design models
Answer: B
Explanation:
Explanation
This approach would be most effective from a MBSE perspective because it allows the system engineer to create a unified view of the design of the system and its components using SysML blocks and relationships. A block is an extension of the UML Class metaclass that can be used to model any system component with structure and behavior. A relationship is a connection between model elements that specifies some kind of dependency or association. By creating a SysML block structure representing the system and its components, the system engineer can capture the hierarchy, composition, classification, generalization, etc., of the system elements. By creating relationships between the blocks and the design models, such as MCAD, ECAD, or Spreadsheets, the system engineer can link the SysML model with the external models and provide traceability and consistency. The system engineer can also use the SysML model to generate a bill-of-materials for the system and its components, as well as to propagate changes made in one design model to another using allocation or synchronization mechanisms.

Choose the correct answer
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. manual exchange
- B. repository-based exchange
- C. file-based exchange
- D. interaction-based exchange
Answer: C
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 are views and viewpoints used to show?
- A. the system under development by the stakeholders
- B. the aspects of a model that relate to different stakeholders
- C. the modeling responsibilities of different stakeholders
- D. the aspects of a model important to users as stakeholders
Answer: B
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:

How should stereotypes be grouped to facilitate re-use in later projects?
- A. in packages
- B. in profiles
- C. in metamodels
- 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:

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:

A systems engineer is responsible for deploying a model-based systems engineering approach on an unprecedented system, with unclear or incomplete user and system requirements.
What is the most important factor the engineer should consider in selecting a system development methodology?
- A. the ability to rapidly prototype the user interface
- B. a robust ontology for characterizing complex systems
- C. access to a large model library and legacy code base
- D. the ability to rapidly explore required system functionality
- E. direct support for quickly characterizing and prototyping services
Answer: D
Explanation:
Explanation
The most important factor that the engineer should consider in selecting a system development methodology for an unprecedented system with unclear or incomplete user and system requirements is the ability to rapidly explore required system functionality. The ability to rapidly explore required system functionality means that the system development methodology can support the elicitation, analysis, validation and verification of the user and system requirements through various techniques, such as use cases, scenarios, prototypes, simulations and tests. The ability to rapidly explore required system functionality can help reduce the uncertainty and ambiguity of the requirements and increase the confidence and satisfaction of the stakeholders. The ability to rapidly prototype the user interface is a less important factor that may not be relevant or applicable to all systems or projects. Access to a large model library and legacy code base is a less important factor that may not be available or suitable for an unprecedented system. A robust ontology for characterizing complex systems is a less important factor that may not be necessary or sufficient for defining the requirements. Direct support for quickly characterizing and prototyping services is a less important factor that may not be relevant or applicable to all systems or projects.
