- A. Define simple structures for artifacts and avoid complex layouts for office documents
- B. SysML already includes a concept for model-driven generation of office documents
- C. Apply stereotypes to model elements to add the metainformation required for the generation process.
- D. Adapt open-source model transformation tools originally developed for the software engineering discipline
Answer: C
Explanation:
Explanation
A common technique for supporting the automated generation of development artifacts from a SysML model is to apply stereotypes to model elements to add the metainformation required for the generation process.
Stereotypes can define tagged values that specify additional information about model elements, such as document templates, formatting options, traceability links, etc. These tagged values can be used by model transformation tools or scripts to generate artifacts from the model. References:

Choose the correct answer
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. a robust ontology for characterizing complex systems
- B. direct support for quickly characterizing and prototyping services
- C. access to a large model library and legacy code base
- D. the ability to rapidly explore required system functionality
- E. the ability to rapidly prototype the user interface
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.

NEW QUESTION # 46
Choose the correct answer.
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:

NEW QUESTION # 47
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.

NEW QUESTION # 48
Choose the correct answer
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.

Which kind of allocation relationship is pivotal m a Y development approach?
- A. requirement to design
- B. property to structure
- C. function to structure
- D. function To code
Answer: C
Explanation:
Explanation
A V development approach is a systems engineering methodology that follows a V-shaped process model. The left side of the V represents the decomposition of requirements into system and subsystem specifications. The bottom of the V represents the integration and testing of system components. The right side of the V represents the verification and validation of system performance against requirements. A function to structure allocation relationship is pivotal in a V development approach, because it defines how the system functions are realized by the system structure (i.e., components). This relationship enables traceability and consistency between requirements, design, implementation, and testing

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
- D. 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
Answer: A
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.

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 quantifiable notion of time and resources
- C. the terminology that is shared with the RT7E domain
- D. a means to quantify interactions between a system and its physical environment
Answer: B
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:

A control unit aboard a ship sends commands to a remote-controlled submarine. which in turn sends messages to the ship after completing each major stage of its overall mission. For each distinct stage, the ship orders the submarine to perform a different set of operations. Completing any given stage takes a widely variable amount of time Why it is appropriate to use the MARTE profile to model this system with SysML?
- A. The stage transitions of the mission equate to a chronometric clock a temporal construct that MARTE brings to SysML
- B. The stage transitions of the mission equate to a logical dock, a temporal construct that MARTE brings to SysML
- C. The control unit is an embedded system, which the MARTE profile makes it possible to model in SysML
- D. The control unit must order the submarine's operations in real time, which the MARTE profile makes it possible to model in SysML.
Answer: D
Explanation:
Explanation
It is appropriate to use the MARTE profile to model this system with SysML because the control unit must order the submarine's operations in real time, which the MARTE profile makes it possible to model in SysML.
MARTE is a UML profile that provides concepts and annotations for modeling and analyzing real-time and embedded systems. It supports modeling time-related properties and constraints, such as deadlines, periods, durations, clocks, etc., as well as resource-related properties and constraints, such as memory, CPU, power, etc. By using MARTE, one can capture the real-time requirements and behavior of the system and perform schedulability and performance analysis.

What characterizes a complete SysML model?
- A. It includes a complete set of SysML constructs and associations for the system being modeled
- B. All of its element trace back to requirements that are within the scope of the project
- C. It uses all SysML diagram types to model all aspects of the system or part being modeled.
- D. It has all the necessary information relevant at the level of abstraction that the model represents.
Answer: D
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

Which data exchange mechanism uses a database that is accessible by two or more tools m order to share data?
- A. file-based exchange
- B. manual exchange
- C. interaction-based exchange
- D. repository-based exchange
Answer: D
Explanation:
Explanation
This type of data exchange mechanism uses a database that is accessible by two or more tools in order to share data. A repository-based exchange is a way of exchanging data between tools that have direct integration or compatibility. It requires the tools to access a common database that stores the data in a standardized format, such as XMI, AP233, etc. A repository-based exchange can be useful for transferring data in real-time or for performing collaborative operations. However, it can also have some drawbacks, such as security, scalability, orperformance issues. References:

- 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:

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 may be applied to 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 ate automatically applied lo the elements sharing compatible metaclasses
Answer: B
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.
