Understanding OCL is important to the understanding of which item(s)?
- A. both the UML and SysML specifications
- B. software developers' modifications to a SysML model
- C. a typical high-level domain model
- D. tool-generated XMI for a SysML model
Answer: A
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 is the most significant deficiency impeding widespread use of SysML (without MARTE) in the real-time and embedded domain?
- A. a means to quantify interactions between a system and its physical environment
- B. the terminology that is shared with the RT7E domain
- C. a quantifiable notion of time and resources
- D. a means to distinguish embedded from non-embedded systems
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 one of the best reasons for a modeling Systems Engineer to use OCL?
- A. OCL facilitates understanding by engineers.
- B. OCL can express any imaginable constraint
- C. OCL transforms easily into code
- D. OCL allows tor precise specification of constraints based on contents of the model
Answer: D
Explanation:
Explanation
OCL is a formal language that can be used to specify constraints on the elements and relationships of a model.
OCL can access the properties and operations of the model elements and check their values and states. OCL is not intended to be transformed into code or to express any imaginable constraint. OCL may not be easily understood by engineers who are not familiar with its syntax and semantics.

What is the key distinction between SysML modeling and MOF modeling?
- A. MOF models are intended to be models of modeling constructs SysML models represent real world entities and processes.
- 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 used for domain-independent modeling SysML models are used for domain-specific modeling.
- D. MOF models are intended to be strictly models of abstract entities SysML models represent real world entities and processes
Answer: A
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.

- A. which activities will interact with external systems
- B. which artifacts need to be produced when executing the tailored activities
- 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: B
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

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. 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
- B. the high cost of maintaining modeling tools and modeling proficiency training, and potential advantages of teaming arrangements with vendors
- C. how well any proposed MBSE methodology interfaces with the company's Model Driven Software Development methodology, and how this is facilitated by PLM tools
- D. how manufacturing, lest and integration methods can be driven by system models, and how this is facilitated by PLM tools
- E. 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
Answer: A
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.

In a scenario-based development approach, which SysML diagram type could best be used to describe the scenarios?
- A. state diagram
- B. activity 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.

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

- C. how field support operations can be modeled using MBSE methods
- D. how operational evaluation (OPEVAL) plans can be developed and cross-checked In a system modeling environment, using DoDAF operational views
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.

Choose the correct answer.
Given the following diagram fragment:
Which criterion indicates that a decision node construct such as this is well-formed?
- A. Taken together, the guards cover all possibilities and are mutually exclusive.
- B. Each guard legal can be evaluated without changing the state of any item referenced by the corresponding activity or action Ai
- C. No activity Ai will negate the corresponding guard [gi]
- D. The guards are understandable by stakeholders in the development effort.
Answer: A
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.
NEW QUESTION # 41
Choose the correct answer
A systems engineer is establishing a viewpoint whose purpose is to support performance analysis.
Which combination of SysML diagram types would the engineer be most likely to choose for the viewpoint languages?
- A. sequence and state diagrams
- B. block definition and package diagrams
- C. parametric and activity diagrams
- D. use case and requirements diagrams
Answer: C
Explanation:
Explanation
Parametric and activity diagrams are suitable for performance analysis because they can capture the quantitative aspects of a system, such as parameters, constraints, equations, values, units, flows and rates.
Sequence and state diagrams are more focused on the temporal and behavioral aspects of a system, such as interactions, events and states. Use case and requirements diagrams are more focused on the functional and non-functional aspects of a system, such as actors, scenarios and goals. Block definition and package diagrams are more focused on the structural and organizational aspects of a system, such as blocks, parts, ports, connectors and packages.

Which SysML diagram type is a modification of the UML Class diagram?
- A. Internal Block Diagram
- B. Block Definition Diagram
- C. Parametric Diagram
- D. Package Diagram
Answer: B
Explanation:
Explanation
The SysML diagram type that is a modification of the UML Class diagram is the Block Definition Diagram (BDD). A BDD shows the definition of blocks in terms of their features, such as properties, operations, ports, etc. It is similar to a UML Class diagram, but it adds some features specific to SysML, such as value types, units, flow properties, etc. A block is an extension of the UML Class metaclass that can be used to model any system component with structure and behavior.

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 XMI. the ability to enforce strict compliance with UML4SysML. and the ability to query models based on user-defined criteria
- B. the ability to enforce strict compliance with XMI. AP233 and SysML standards
- C. compatibility with AP233; the ability to enforce strict compliance with the SysML standard; and the ability to query models based on user-defined criteria
- D. compatibility with XMI. the ability to enforce strict compliance with the SysML standard and the ability to query models based on user- defined criteria
Answer: D
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:
