What is a best practice to link actions of an activity in a SysML model to a software application described in a UML model?
- A. The actions are copied into the UML model using the copy relationship.
- B. The actions in the SysML model are called by appropriate CallBehaviorActions in the UML model
- C. The actions are moved into the namespace of the UML model
- D. The actions are assigned to an activity partition that represents the software application
Answer: B
Explanation:
Explanation
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. References:

What are some general rules to be applied at the end of requirements analysis to determine that (1) an activity diagram is self-consistent and (2) all elements on the diagram belong there' Select the option that gives the most general answer without including any irrelevant rules
- A. Every diagram element is traceable to a requirement, use case or undocumented user need. (2) Every input object can be traced through the diagram to (a) an output object, buffer, data store or the object is consumed without producing any other object (3) .There is a path from the initial node to every activity final and How final node.(b) an action that clearly states how
- B. Every diagram element is traceable to a requirement or use case (2) Every Input object can be traced through the diagram to (a) an output object, buffer, or data store how the object is consumed without producing any other object fv (3) There Is a path from the initial node to every activity final and flow final nodeor (b) an action that clearly states
- C. Every diagram element is traceable to a requirement or use case. (2) Every input object can be traced through the diagram to an output object, butler, or data store. (3) There Is a path from the initial node to every activity final and flow final node
- D. Every diagram element is traceable to a requirement or use case (2) Every input object can be traced through the diagram to (a) an output object, buffer or data store how the object is consumed without producing any other object. (3) There is a path from the initial node to every activity final and flow final node (4) The diagram has no cycles of control flows or (b) an action that clearly states
Answer: B
Explanation:
Explanation
Option C gives the most general answer without including any irrelevant rules. Option A is incorrect because it does not account for the possibility of an input object being consumed without producing any other object.
Option B is incorrect because it introduces the concept of undocumented user need, which is not part of the requirements analysis. Option D is incorrect because it adds an unnecessary rule about cycles of control flows, which are not prohibited in activity diagrams.

Choose the correct answer
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. allocations and stereotypes
- C. packages and parametrics
- D. requirement relationships and allocations
Answer: B
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.

Choose the correct answer
In a scenario-based development approach, which SysML diagram type could best be used to describe the scenarios?
- A. requirements diagram
- B. activity diagram
- C. use case diagram
- D. state diagram
Answer: C
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.

In addition to selecting the methodology activities to be performed, what other tailoring does the systems modeling team need to consider when defining the project methodology?
- A. which artifacts need to be produced when executing the tailored activities
- B. which activities will interact with external systems
- C. which requirements will be allocated to the specialty engineering activities
- D. which kind of diagrams will be used to create the domain model
Answer: A
Explanation:
Explanation
An artifact is a tangible or intangible product or outcome of an activity or process. Examples of artifacts include models, diagrams, documents, reports, etc. When defining the project methodology, the systems modeling team needs to consider which artifacts need to be produced when executing the tailored activities, because this determines what information needs to be captured, communicated, and delivered throughout the project lifecycle. The artifacts should be aligned with the project objectives, scope, deliverables, and quality standards

What distinguishes a software development methodology from a systems development methodology?
- A. All current systems development methodologies are extensions of previous software development methodologies.
- B. Software development methodologies employ formal architecting techniques, while systems development methodologies tend not to.
- C. For software intensive systems, there is effectively no difference between system development methodologies and software development methodologies
- D. Systems development methodologies tend to focus on holistic issues, while software development methodologies tend to focus on high quality code.
- E. There is no difference Any methodology good for software development should be good for systems development.
Answer: D
Explanation:
Explanation
The main difference between software development methodologies and systems development methodologies is that software development methodologies tend to focus on high quality code, such as functionality, reliability, performance and maintainability, while systems developmentmethodologies tend to focus on holistic issues, such as stakeholder needs, system boundaries, interfaces, trade-offs and lifecycle management.
Software development methodologies are usually applied to software-intensive systems or subsystems, while systems development methodologies are usually applied to complex systems that involve multiple disciplines and domains. It is not true that all current systems development methodologies are extensions of previous software development methodologies, as some systems development methodologies have different origins and foundations. It is not true that software development methodologies employ formal architecting techniques, while systems development methodologies tend not to, as both types of methodologies can use different levels of formality and rigor in their architecting approaches. It is not true that for software intensive systems, there is effectively no difference between system development methodologies and software development methodologies, as software intensive systems still require a broader and deeper perspective than software development methodologies can provide. It is not true that there is no difference between any methodology good for software development and any methodology good for systems development, as different types of systems may require different types of methodologies that suit their characteristics and challenges.

What is the most significant deficiency impeding widespread use of SysML (without MARTE) in the real-time and embedded domain?
- A. the terminology that is shared with the RT7E domain
- B. a means to quantify interactions between a system and its physical environment
- C. a means to distinguish embedded from non-embedded systems
- D. a quantifiable notion of time and resources
Answer: D
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:

NEW QUESTION # 58
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. 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
- 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. 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
- 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

How does SysML support systems engineering methodologies?
- A. SysML does not support system engineering methodologies, as it is a language
- B. SysML can only support a systems engineering methodology if it is used at the starting point of the project
- C. The generalization mechanism enables fitting of SysML to a methodology
- D. The stereotype and profile mechanisms enable lilting of SysML to a methodology.
Answer: D
Explanation:
Explanation
SysML is a general-purpose modeling language for systems engineering that can support various systems engineering methodologies. The stereotype and profile mechanisms are features of SysML that enable customizing and extending the language for a specific domain or purpose. By using stereotypes and profiles, SysML can be adapted to fit different methodologies and conventions without changing the core language semantics

Given the following diagram fragment:
Which criterion indicates that a decision node construct such as this is well-formed?
- A. No activity Ai will negate the corresponding guard [gi]
- B. Each guard legal can be evaluated without changing the state of any item referenced by the corresponding activity or action Ai
- C. The guards are understandable by stakeholders in the development effort.
- D. Taken together, the guards cover all possibilities and are mutually exclusive.
Answer: D
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.

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. It has all the necessary information relevant at the level of abstraction that the model represents.
- D. All of its element trace back to requirements that are within the scope of the project
Answer: C
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

Choose the correct answer
A project is developing a distributed information system that will be "open" in the following ways.
(a) The system-level models will be published for the world to see.
(b) Others will be encouraged to submit change requests to the system models. (Changes will be identified by stereotypes.) (c) Others will be encouraged to develop additional subsystems and plug-ins The information system is expected to be in use for at least ten years What is(are) the most important consideration(s) in selecting a SysML modeling tool for this project?
- A. compatibility with AP233; the ability to enforce strict compliance with the SysML standard; and the ability to query models based on user-defined criteria
- B. compatibility with XMI. the ability to enforce strict compliance with the SysML standard and the ability to query models based on user- defined criteria
- C. the ability to enforce strict compliance with XMI. AP233 and SysML standards
- D. compatibility with XMI. the ability to enforce strict compliance with UML4SysML. and the ability to query models based on user-defined criteria
Answer: B
Explanation:
Explanation
These are the most important considerations in selecting a SysML modeling tool for this project because they ensure that the tool can support the openness and longevity of the distributed information system. 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 having compatibility with XMI, the tool can import and export SysML models in terms of XML elements and attributes. This allows the tool to publish the system-level models for the world to see and to receive change requests from others in a standardized format. The tool can also use stereotypes to identify changes made by others. The SysML standard is an extension of the UML standard that defines a modeling language for systems engineering. It specifies the abstract syntax, semantics, and notation for SysML concepts and diagrams. By having the ability to enforce strict compliance with the SysML standard, the tool can ensure that the system-level models are consistent and interoperable with other tools and models that follow the same standard. The tool can also support others to develop additional subsystems and plug-ins using SysML concepts and diagrams. By having the ability to query models based on user-defined criteria, the tool can enable users to search and filter system-level models according to their needs and interests. The tool can also support visualization and analytics of system-level models using queries. References:

NEW QUESTION # 64
Choose the correct answer
Which relationship is likely to be most heavily used during requirements analysis?
- A. copy
- B. refine
- C. verify
- D. satisfy
Answer: B
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.

Understanding OCL is important to the understanding of which item(s)?
- A. tool-generated XMI for a SysML model
- B. both the UML and SysML specifications
- C. a typical high-level domain model
- D. software developers' modifications to a SysML model
Answer: B
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.

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.

What is the purpose of the Domain Metamodel in UPDM?
- A. It defines the stakeholder requirements for the metamodel.
- B. It defines the mapping of UML to SysML and SOAML concepts
- C. It defines the melamodel concepts and relationships without any implementation
- D. It defines the implementation metamodel.
Answer: C
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.

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. create a SysML block structure representing (he system and its components, and then create relationships between the blocks and the design models
- B. import each design model into a separate SysML model, link the SysML models together, and then create relationships between the design models
- C. import each design model into a single SysML model and then create relationships between the design models
- D. create a SysML package structure representing the system and its components, and then create relationships between the packages and the design models
- E. create a SysML activity structure representing the design process of each component, and then create relationships between the activity parameters and the design models
Answer: A
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.
