Question 1

Choose the correct answer

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

A system engineer designing a smart-home system is working with three analysts using specialized computational tools to evaluate energy consumption, waste production, and reliability of the system The team is soliciting a recommendation for an approach that achieves the following

(1) Analysis models should Incorporate design details necessary for evaluation

(2) Analysis models should be easily adaptable for different types of smart-home systems

Which recommendation would be most effective from a MBSE perspective'?



Answer : A, 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.

Question 3

Choose the correct answer

A system modeler exports requirements from a requirements management tool into a spreadsheet and then imports the requirements into a system modeling tool.

Which type of data exchange is this considered?



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.

Question 4

Choose the correct answer.

A team of designers led by a hardware systems engineer is finding it difficult to manage the design of a distributed air-conditioning system_ Each system component Is a complex assembly with multiple design models (such as MCAD. ECAD, and Spreadsheets). The system engineer wants to architect an approach that achieves the following

(1) provides a unified view of the design of the system and Its components

(2) provides a unified model for generating a bill-of-materials

(3) provides sufficient semantics to propagate changes made in one design model to another

Assume that the system engineer Is allocated resources to purchase or develop the new software required for this architecture

Which approach would be most effective from a MBSE perspective?



Answer : C

This approach would be most effective from a MBSE perspective because it allows the system engineer to create a unified view of the design of the system and its components using SysML blocks and relationships. A block is an extension of the UML Class metaclass that can be used to model any system component with structure and behavior. A relationship is a connection between model elements that specifies some kind of dependency or association. By creating a SysML block structure representing the system and its components, the system engineer can capture the hierarchy, composition, classification, generalization, etc., of the system elements. By creating relationships between the blocks and the design models, such as MCAD, ECAD, or Spreadsheets, the system engineer can link the SysML model with the external models and provide traceability and consistency. The system engineer can also use the SysML model to generate a bill-of-materials for the system and its components, as well as to propagate changes made in one design model to another using allocation or synchronization mechanisms.

Question 5

Choose the correct answer

What kind of models can be exchanged using XMI?



Answer : C

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. Reference: https://www.omg.org/ocsmp/ocsmp-adv-exam.htm https://www.omg.org/spec/XMI/2.5.1/About-XMI/


Question 6

Choose the correct answer

For a system with stringent real-time requirements and power-consumption constraints, which concern would lead the designer to employ the MARTE profile?



Answer : A

For a system with stringent real-time requirements and power-consumption constraints, the concern that would lead the designer to employ the MARTE profile is ensuring that the structure could be precisely modeled and that analysis was supported. MARTE provides concepts and annotations for modeling the structure of real-time and embedded systems in terms of components, ports, connectors, flows, etc., as well as for modeling their behavior in terms of state machines, activities, etc. MARTE also provides concepts and annotations for performing analysis of system properties, such as schedulability, performance, power consumption, etc., using various methods and tools.

Question 7

Choose the correct answer.

What is common practice when integrating software models into SysML system models?



Answer : C

The common practice when integrating software models into SysML system models is to define cross-relationships between a UML software model and a SysML system model. A cross-relationship is a dependency that indicates a link between elements in different models or domains. By using cross-relationships, one can establish traceability and consistency between the software model and the system model without having to merge or transform them. Cross-relationships can also support allocation of software components to hardware or other software components in the system model.
