• Question 61:

  Choose the correct answer

  Which relationship is likely to be most heavily used during requirements analysis?

  A. copy

  B. refine

  C. satisfy

  D. verify

  Correct Answer: B

  The refine relationship is likely to be most heavily used during requirements analysis because it is used to indicate that a model element provides more details or information about a requirement. The refine relationship can be used to link requirements to other requirements, use cases, activities, blocks or any other model elements that can help clarify or elaborate the requirements. The refine relationship can also be used to decompose a requirement into sub-requirements or to show how a requirement is derived from another requirement. The copy relationship is used to indicate that a requirement is identical to another requirement. The satisfy relationship is used to indicate that a design element fulfills a requirement. The verify relationship is used to indicate that a test case or procedure confirms that a design element satisfies a requirement.

• Question 62:

  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

  A. The 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

  B. The 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.

  C. The 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.

  D. The 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

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

  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.

• Question 63:

  Choose the correct answer

  Which data exchange mechanism uses an application programming interface (API) to access data m one tool and make it available in another tool?

  A. manual exchange

  B. file-based exchange

  C. interaction-based exchange

  D. repository-based exchange

  Correct Answer: C

  Interaction-based exchange is a data exchange mechanism that uses an application programming interface (API) to access data in one tool and make it available in another tool. The API allows for direct communication and synchronization between the tools without requiring intermediate files or repositories. This approach can provide better performance and consistency than file-based or repository-based exchange.

• Question 64:

  Choose the correct answer

  What does a model library add to a SysML model?

  A. stereotypes

  B. common concepts

  C. domain-specific modeling concepts

  D. methodology-specific modeling concepts

  Correct Answer: B

  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.

• Question 65:

  Choose the correct answer

  What can be included in a model library?

  A. any model element

  B. any model element that Is contained In a profile

  C. any model element that can be contained in a package

  D. only those model elements that are re-used in the model

  Correct Answer: C

  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 <> applied to it. It contains reusable model elements that can be imported into other models by using an 玦mport?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.

• Question 66:

  Choose the correct answer.

  An engineer has defined a profile, SE2Profile, for the APE model. Another model, E-ELT, requires the same profile.

  What is the best way to share the profile?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: B

  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 <> applied to it. It contains reusable model elements that can be imported into other models by using an 玦mport?relationship. Option B shows this approach.

• Question 67:

  Choose the correct answer

  A design team is applying the MARTE profile to its model to add information about timing and resources

  What is a best practice to provide the MARTE information to the engineers who require it?

  A. Define a viewpoint and conform views for the engineers

  B. Always show the MARTE stereotypes and properties in the diagrams

  C. Define a model library that encapsulates the MARTE data for the engineers

  D. Create a separate model for the MARTE data and import it into the system model.

  Correct Answer: A

  A best practice to provide the MARTE information to the engineers who require it is to define a viewpoint and conform views for the engineers. A viewpoint is a specification of a perspective on a model that addresses a set of stakeholder concerns. A view is a representation of a model that conforms to a viewpoint. By defining a viewpoint and conform views for the engineers, the MARTE information can be presented in a way that is relevant and understandable for them.

• Question 68:

  Choose the correct answer.

  Which element would be used to depict a model library on a diagram?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: C

  The element that would be used to depict a model library on a diagram is a package with the stereotype <> applied to it. This stereotype indicates that the package contains reusable model elements that can be imported into other models. Option C shows a package with this stereotype

• Question 69:

  Choose the coned answer

  Which kind of allocation relationship is pivotal m a Y development approach?

  A. function To code

  B. property to structure

  C. requirement to design

  D. function to structure

  Correct Answer: D

  A V development approach is a systems engineering methodology that follows a V-shaped process model. The left side of the V represents the decomposition of requirements into system and subsystem specifications. The bottom of the V represents the integration and testing of system components. The right side of the V represents the verification and validation of system performance against requirements. A function to structure allocation relationship is pivotal in a V development approach, because it defines how the system functions are realized by the system structure (i.e., components). This relationship enables traceability and consistency between requirements, design, implementation, and testing

• Question 70:

  Choose the correct answer

  is it possible to conduct a systems engineering project without applying a methodology?

  A. Yes. if only the project's tasks are defined

  B. Yes. it only the project's processes are defined.

  C. No. system engineering projects will fail if no dedicated methodology is applied

  D. No. even it r>o formal methodology is applied, working spontaneously is considered to be a methodology

  Correct Answer: D

  A methodology is a set of principles, methods and practices that guide the execution of a project or activity. A systems engineering project always involves some kind of methodology, even if it is not explicitly defined or documented. Working spontaneously or randomly is also a form of methodology, although it may not be very effective or efficient. A systems engineering project cannot be conducted without applying any methodology at all.
