Free and Premium OMG OMG-OCSMP-MBA400 Dumps Questions Answers

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.

The OMG specifications that UPDM uses at L1 are UML and SysML. L1 is the level of abstraction that defines the core concepts of UPDM without any implementation details. It is based on a Domain Metamodel that captures the common elements of DoDAF and MODAF. The Domain Metamodel is mapped to UML and SysML concepts using a Platform Independent Model (PIM). UML and SysML provide the basic metaclasses and diagrams that UPDM uses to represent architectures. References:

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.

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

To force modelers to use particular metamodeling features, the supervisor must «apply» the profile to the model with the {strict} keyword applied. This keyword indicates that only elements with stereotypes defined in the profile can be created as instances of the extended metaclasses. For example, if a profile defines a stereotype <> as an extension of Class, then only classes with this stereotype can be created as instances of Class when the profile is applied with the {strict} keyword.

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:

OCL stands for Object Constraint Language, which is a standard language for expressing constraints on UML and SysML models. Constraints are used to specify additional rules or conditions that are not directly captured by the modeling elements or their relationships. OCL can be used to define constraints on stereotypes, their properties, or their relationships in a profile. References:

The element that would be used to depict a model library on a diagram is a package with the stereotype <> applied to it. This stereotype indicates that the package contains reusable model elements that can be imported into other models. Option C shows a package with this stereotype. References:

A best practice to provide the MARTE information to the engineers who require it is to define a viewpoint and conform views for the engineers. A viewpoint is a specification of a perspective on a model that addresses a set of stakeholder concerns. A view is a representation of a model that conforms to a viewpoint. By defining a viewpoint and conform views for the engineers, the MARTE information can be presented in a way that is relevant and understandable for them. References:

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.

A method is a technique or procedure for performing a specific task. A method is not generic and cannot be used out-of-the-box, because it depends on the context and purpose of the task. A method is not unnecessary to build an effective SysML model, because it provides guidance and structure for the modeling process. A method does not depend on the specific features of the modeling language, because it can be applied to different languages with appropriate adjustments. Therefore, a method must be adapted to company or project specific needs, because it should reflect the goals, requirements, constraints, and preferences of the stakeholders involved in the project

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:

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.
