OMG-OCSMP-MBA400 Online Practice Questions and Answers

Correct Answer: B

A common rationale for defining and applying a profile to a SysML model is that the profile extends the model with reusable elements, such as units, quantities, value types, etc. These elements can be defined in a model library and imported into other models by applying the profile. This way, the profile enables consistent and standardized modeling of properties and parameters of blocks and constraints.

Correct Answer: A

This aspect of a MBSE-based engineering project falls outside of the scope of AP233 because AP233 does not cover diagrams. AP233 (Application Protocol 233) is a standard that defines an information model for systems engineering. It specifies the concepts and relationships for representing systems engineering data, such as requirements, functions, properties, etc. AP233 does not define any notation or presentation for diagrams, such as SysML diagrams. AP233 only defines the serialization and deserialization of systems engineering data using XMI (XML Metadata Interchange) format. Therefore, AP233 does not address how to exchange diagrams between tools or how to visualize diagrams in different tools.

Correct Answer: D

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.

Correct Answer: B

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.

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

The next project task to be carried out after identifying the concerns of a group of stakeholders involved in a systems development project is to define a set of viewpoints and align them with concerns. A viewpoint defines how a view should be constructed and used to address a set of stakeholder concerns. By defining and aligning viewpoints with concerns, the project can ensure that each concern is covered by at least one viewpoint, and that each viewpoint addresses one or more concerns.

Correct Answer: A

This feature needs to be added to the systems development environment to conduct a performance simulation because it enables users to solve mathematical equations and models that represent system performance. A numerical solver is a software tool that can perform numerical analysis and computation on a given problem or model. A numerical solver can help users to evaluate system performance by solving equations that describe system behavior, properties, constraints, etc. A numerical solver can also help users to optimize system performance by finding optimal solutions or trade-offs for a given problem or model.

Correct Answer: C

The diagram fragment that correctly expresses the requirement that the model must only be built using the constructs defined in the Quality profile is Option C. This option shows an Apply relationship between the model and the profile with the {strict} keyword applied. This means that only elements with stereotypes from the Quality profile can be created as instances of the extended metaclasses.
