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

Amanual exchange

Bfile-based exchange

Cinteraction-based exchange

Drepository-based exchange

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 3

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'?

AThe system engineer should create a SysML model loi capturing the design ol different types of smart-home systems, and the analysts
should set up executable templates/scripts to generate analysis models from the SysML model

AThe system engineer should create a SysML model for capturing high-level design specifications of different types of smart-home
systems, which the analysts can consult for creating and maintaining analysis models in their individual tools.

CThe system engineer should create a SysML model for capturing the design of different types of smart-home systems, and the analysts
should each create a SysML model representing their specific analysis. All four SysML models should then be linked together.

DThe system engineer should create a SysMI model for capturing the high level design specifications of different types of smart-home systems. This SysML model should contain a package for each of the analyses and dependency relations between the design specifications and the analysis packages

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 4

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?

Amanual exchange

Bfile-based exchange

Cinteraction-based exchange

Drepository-based exchange

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 5

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?

Aimport each design model into a single SysML model and then create relationships between the design models

Bimport each design model into a separate SysML model, link the SysML models together, and then create relationships between the design models

Ccreate a SysML block structure representing (he system and its components, and then create relationships between the blocks and the design models

Dcreate a SysML package structure representing the system and its components, and then create relationships between the packages and the design models

Ecreate a SysML activity structure representing the design process of each component, and then create relationships between the activity parameters and the design models

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 6

Choose the correct answer

What kind of models can be exchanged using XMI?

Aonly UML models including profiles

Bonly UML and SysML models

Cinstances of MOF models

Dinstances of metamodels that can be described by an XML schema

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 7

Choose the correct answer

A company is executing a large distributed engineering project. More than a dozen engineers are contributing to the system model, working from different locations spread across three time zones The lead engineer has decided that it is essential to maintain a single model. The department director has expressed concern that the project may have trouble employing its engineers productively while still maintaining configuration control of this common model.

Which configuration management strategy is likely to be most successful*?

AUse a centralized repository for the model files Allow only engineers in the eastern-most time zone to upload changes to the model files in the mornings, and the western engineers in the afternoons. Either can download and view the model files at any time. This will assure maximum productivity while minimizing the possibility of collisions

BUse a configuration management tool to manage model elements. Assign ownership of model elements at the package level- Only the owner of a package may make changes to elements in that package Note that each relationship between model elements must be
contained within a single package

CUse a configuration management tool to manage model elements. Allow packages to be checked out by any user for editing, which locks the elements therein contained Packages may be viewed in read-only mode by any user at any time All model users receive alerts when a package they are viewing has been modified and checked-in. and changes are highlighted Packages may not remain checked out overnight

DCo-locate the modeling team Trying to maintain configuration of a model across a distributed team is extremely difficult and may not succeed

Answer : C

This configuration management strategy is likely to be most successful because it allows the engineers to work on the system model collaboratively and concurrently, while maintaining configuration control and avoiding conflicts. A configuration management tool is a software tool that helps manage changes to model elements and track their versions and history. A package is a grouping mechanism that can contain any kind of model element, such as diagrams, blocks, activities, etc. By using a configuration management tool, the engineers can check out packages for editing, which locks the elements in that package and prevents other users from modifying them. The engineers can also view packages in read-only mode by any user at any time, which allows them to see the latest version of the model without affecting it. The engineers can also receive alerts when a package they are viewing has been modified and checked-in by another user, and see the changes highlighted. This way, the engineers can stay informed and synchronized with the model updates. By not allowing packages to remain checked out overnight, the engineers can avoid holding up the work of other users who need to access or modify those packages.
