Important OMG-OCSMP-MBA400 Exam Questions

Answer: A

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.

Answer: B

Explanation:

The best way to share the profile is to define it as a model library and import it into the other model. A model library is a package with the stereotype <<modelLibrary>> applied to it. It contains reusable model elements that can be imported into other models by using an import relationship. Option B shows this approach.

Answer: C

Explanation:

Any model element that can be contained in a package can be included in a model library. A model library is a package with the stereotype <<modelLibrary>> applied to it. It contains reusable model elements that can be imported into other models by using an import relationship. Any kind of model element that can be owned by or nested within a package can be part of a model library, such as blocks, constraints, values, units, etc. Reference: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://www.omg.org/spec/SysML/1.6/PDF

Answer: B

Explanation:

This modeling approach should be used by the system engineer because it allows him to capture the behavior of his system-of-interest using SysML activities and actions. An activity is a behavior that specifies the coordination of actions. An action is a behavior that specifies a transformation or processing of data. By using activities and actions, the engineer can model the algorithm and its functions in terms of inputs, outputs, control flows, object flows, parameters, etc. He can also use allocations to relate the activities and actions to other model elements, such as blocks or requirements. This way, he can generate MATLAB code from his SysML model for execution and testing. Reference: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://sysml.org/tutorials/sysml-diagram-tutorial/

Answer: B

Explanation:

A model library is a package that contains reusable model elements that can be imported into other models. A model library can add common concepts to a SysML model, such as units, quantities, value types, etc. These concepts can be used to define properties and parameters of blocks and constraints in a consistent and standardized way.
