Which data exchange mechanism uses a database that is accessible by two or more tools m order to share data?



Answer : D

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, or performance issues. Reference: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://www.omg.org/spec/AP233/About-AP233/


Question 2

Choose the correct answer.

How should stereotypes be grouped to facilitate re-use in later projects?



Answer : A

Stereotypes should be grouped in profiles to facilitate re-use in later projects. A profile is a mechanism for extending UML or SysML with additional modeling elements that are not part of the standard language. A profile defines stereotypes, which are extensions of existing metaclasses. A profile can be applied to a model to make the stereotypes available for use. By grouping stereotypes in profiles, they can be easily reused in different models or projects.

Question 3

Choose the correct answer.

What is a common rationale for defining and applying a profile to a SysML model?



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.

Question 4

What is best practice to model a software application in a SysML model for a system?



Answer : A

The best practice to model a software application in a SysML model for a system is to use a block stereotyped with software to represent the software application and its interfaces. A block is a modular unit that encapsulates its structure and behavior and can be connected to other blocks via ports and connectors. A stereotype is an extension of an existing metaclass that adds additional information or semantics to a model element. By using a block stereotyped with software, the software application can be modeled as a system component with its own properties, operations, ports, flows, etc., and can be allocated to hardware blocks or other software blocks.

Question 5

Choose the correct answer.

A modeling team supervisor has defined a stereotype of block named *projectBlock and wants to prevent any use of an unstereotyped block

What must the supervisor do?.



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.

Question 6

Choose the correct answer.

What is one of the most common reasons to utilize a SysML-Modehca integration?



Answer : B

One of the most common reasons to utilize a SysML-Modelica integration is to solve and analyze system dynamics models. Modelica is a language for modeling complex physical systems based on equations and components. SysML is a language for modeling complex systems based on diagrams and textual notations. By integrating SysML and Modelica, system dynamics models can be defined in SysML using parametric diagrams and constraint blocks, and then solved and analyzed using Modelica tools and solvers.

Question 7

Choose the correct answer

What is the purpose of the Domain Metamodel in UPDM?



Answer : D

The purpose of the Domain Metamodel in UPDM is to define the metamodel concepts and relationships without any implementation. The Domain Metamodel captures the core concepts of DoDAF and MODAF in terms of entities, attributes, associations, and constraints. It does not specify how these concepts are implemented in UML, SysML, or any other language or tool. The Domain Metamodel serves as a requirements model for UPDM and provides traceability links between the domain concepts and the profile elements.
