Question 1

Choose the correct answer

A systems engineer is responsible for deploying a model-based systems engineering approach on an unprecedented system, with unclear or incomplete user and system requirements.

What is the most important factor the engineer should consider in selecting a system development methodology?

Athe ability to rapidly prototype the user interface

Baccess to a large model library and legacy code base

Ca robust ontology for characterizing complex systems

Dthe ability to rapidly explore required system functionality

Edirect support for quickly characterizing and prototyping services

Answer : D

Question 2

Choose the correct answer-.

Which technique allows a user to objectively determine the best means of implementing a particular (unction?

Aa trade study

Ban objective analysis

Coperational research

Da requirements analysts

Answer : A

A trade study is a method for making a decision between competing alternatives based on a set of criteria, such as cost, performance, reliability, etc. A trade study allows a user to objectively determine the best means of implementing a particular function by evaluating and comparing the pros and cons of each alternative.A trade study can also help identify trade-offs and risks associated with each alternative

Question 3

Choose the correct answer

What is the forward temporal order of these development stages?

* needs analysis

* system acceptance

* system design * trade study

Aneeds analysis, system acceptance, system design, trade study

Bneeds analysis, system design, system acceptance, trade study

Cneeds analysis, system design, trade study, system acceptance

Dneeds analysis, trade study, system design, system acceptance

Etrade study, needs analysis, system design system acceptance

Answer : C

The forward temporal order of these development stages is based on the typical sequence of activities in a system engineering process. Needs analysis is the first stage, where the problem and the stakeholder needs are defined. System design is the second stage, where the system architecture and requirements are developed. Trade study is the third stage, where alternative solutions are evaluated and compared based on various criteria. System acceptance is the final stage, where the system is verified, validated, and delivered to the customer.

Question 4

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?

Amanual exchange

Bfile-based exchange

Cinteraction-based exchange

Drepository-based exchange

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 5

Choose the correct answer

An engineer using SysML modeling tool B imports an XMI die produced by SysML modeling tool A (containing a complete model) and makes changes to the model

What is the best way XMI provides to introduce the changes back to the original model in the original tool (Tool A)?

AExport only the modified and new elements to XMI and import it to Tool A.

BProduce a special XMI file expressing the differences from the original XMI and import it into Tool A

CPartition the models and exchange parts of the models alter identifying the parts that were changed.

DImport the entire model back to Tool A as a separate copy and use the tool's diff/merge utility to merge in the changes

Answer : B

XMI is a standard format for exchanging metadata information via XML, such as UML models. XMI supports a mechanism for producing a special XMI file that contains only the differences between two versions of a model, called a difference model. This file can be imported into another tool to apply the changes to the original model.This approach is more efficient and reliable than exporting and importing the entire model or parts of it

Question 6

Choose the correct answer

A bank manager and his core team want to consolidate internal processes, detect conflicts among processes, and improve customer experience. The core team includes the lead person from each of the process areas (such as transactions, customer management, and marketing). The manager wants to architect the overall system processes based on the following.

(1) Relationships among the internal processes should be clearly identifiable and managed.

(2) The core team members should be able to improve their processes simultaneously.

(3) The architecture should aid visualization and analytics

Which model organization approach would be most efficient?

Acreate a SysML model for each of the core processes and for each relationship between processes

Bcreate a SysML model that contains only one diagram showing all the core processes and their relationships

Ccreate a SysML model for each of the core processes, and manage relationships between processes in a spreadsheet

Dcreate a SysML model that contains a package for each of the core processes, and a package for the overall consolidated process and related relationships

Ecreate a SysML model that contains a package for each of the core processes, a package for each of the relationships between processes, and a package for the overall consolidated process

Answer : E

This model organization approach would be most efficient because it allows the bank manager and his core team to modularize and structure their system processes using SysML packages. A package is a grouping mechanism that can contain any kind of model element, such as diagrams, blocks, activities, etc. By creating a package for each of the core processes, the team members can work on their own processes independently and concurrently. By creating a package for each of the relationships between processes, the team can identify and manage the dependencies and interactions among the processes. By creating a package for the overall consolidated process, the team can have a holistic view of the system and perform visualization and analytics using SysML diagrams and parametrics.

Question 7

Choose the correct answer

The lead systems engineer on a project has identified a set of Key Performance Parameters (KPPs) that need to be evaluated both on a periodic basis during development, and during acceptance for every design change. Many of these KPPs are expressed In complex, interrelated differential equations The analysis team has identified appropriate numerical techniques for solving these equations and expressed them in a popular analysis tool.

The lead system modeler and methodologist must ensure that the architecture and design captured in the SysML system model are continuously and accurately reflected In the KPP calculations.

Which strategy is likely to be most successful in accomplishing this?

ATask the analysis learn with recasting each of the KPP equations as constraint blocks and parametric models directly in SysML and linking the resulting parameters to value properties of current system model elements Keeping all information in the same model is the only way to guarantee the consistency the lead engineer has asked for

BList the parameters used to evaluate the KPPs in a spreadsheet file. Use the SysML modeling tool's inherent capability to link appropriate value properties to cells in this spreadsheet Task the analysis team with modifying their analysis routines to accept parameters as an input vector from this spreadsheet. Ensure that the spreadsheet is updated from the system model prior to each update of the KPP calculations

CWork with the analysis team to partition the KPP evaluation model into manageable, reusable subroutines Develop constraint blocks within the SysML model to represent these subroutines, exposing their parameters. Use these new constraint blocks to build a parametric model that ties the KPP evaluation directly to system model element value properties. Leverage available bridging software to link this parametric model to the evaluation subroutines executing in the external analysis tool, and re-evaluate the KPPs on an as-needed basis

DUse activity and/or state models to accurately model the flow of data to numerically solve the KPP evaluation equations Ensure that the analysis team validates these behavior models Bind each relevant value property within the system model to an activity parameter or state variable such that the KPP evaluation model accurately reflects how the KPPs are derived. Next, use code generation capability inherent in the SysML tool to generate and compile the KPP evaluation routines Recompile and run these routines as needed to update KPP estimates
