OMG-OCSMP-MBA400 Online Practice Questions and Answers

Correct Answer: B

Working in UPDM compliance level 1 allows users to bring SysML elements into the architecture to enhance the hand-off between Systems of Systems and Systems. Compliance level 1 is based on UML and SysML concepts and provides integration with system modeling using SysML. Users can use SysML elements, such as blocks, ports, connectors, parametrics, etc., to model system components and their interactions in more detail and precision than using UML elements alone. This can facilitate the transition from architecture modeling to system design and analysis.

Correct Answer: D

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.

Correct Answer: C

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.

Correct Answer: D

The frame of the diagram that corresponds to a model library is the one that has the label "modelLibrary" in its upper left corner. This label indicates that the diagram is contained within a package with the stereotype <> applied to it. Option D shows a diagram with this label.

Correct Answer: B

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.

Correct Answer: B

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

Correct Answer: B

The information that is required to define a viewpoint in SysML in addition to stakeholders is concerns, languages, methods, and purpose. Concerns are aspects of interest about a system that are addressed by a viewpoint. Languages are notations or modeling techniques used by a viewpoint to represent a view. Methods are processes or guidelines for constructing or interpreting views that conform to a viewpoint. Purpose is an explanation of why and how a viewpoint addresses stakeholder concerns

Correct Answer: C

To prevent any use of an unstereotyped block, the supervisor must mark the extending stereotype with the {strict} keyword. This keyword indicates that only elements with this stereotype can be created as instances of the extended metaclass. In this case, only blocks with the stereotype <> can be created as instances of Block.

Correct Answer: A

This recommendation would be most effective from a MBSE perspective because it allows the system engineer and the analysts to leverage the SysML model as a source of design information and analysis input. A SysML model is a graphical and textual representation of a system and its structure, behavior, requirements, etc. By creating a SysML model for capturing the design of different types of smart-home systems, the system engineer can specify the relevant design details necessary for evaluation, such as parameters, constraints, properties, etc. The analysts can then set up executable templates/scripts to generate analysis models from the SysML model using various methods and tools. This way, the analysts can ensure that their analysis models incorporate the latest design information and are easily adaptable for different types of smart-home systems. The system engineer and the analysts can also use allocation or synchronization mechanisms to link the SysML model and the analysis models and propagate changes between them.

Correct Answer: A

A trade study is a method for making a decision between competing alternatives based on a set of criteria, such as cost, performance, reliability, etc. A trade study allows a user to objectively determine the best means of implementing a particular function by evaluating and comparing the pros and cons of each alternative. A trade study can also help identify trade-offs and risks associated with each alternative
