Question 1

Choose the correct answer.

A project is evaluating several modeling tools which comply in vanous degrees to SysML abstract and concrete syntax The customer will allow some deviation from full compliance, as long as technical risk is minimized.

Which tool characteristics are required for this project?

Afull compliance with abstract syntax, and limited deviations from concrete syntax

Bfull compliance with concrete syntax, and limited deviations from abstract syntax

Climited deviations from abstract and concrete syntax

Dfull compliance with both abstract and concrete syntax, nothing less is adequate

Answer : A

This tool characteristic is required for this project because it ensures that the modeling tool follows the SysML abstract syntax, which defines the metamodel elements and their semantics. The abstract syntax is essential for ensuring consistency and interoperability between different tools and models. The concrete syntax, which defines the notation and presentation of the elements, can have some deviations as long as they do not affect the meaning or interpretation of the model. For example, a tool can use different colors or shapes for some elements without changing their semantics.

Question 2

Choose the correct answer.

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

AOption

BOption

COption

DOption

Answer : C

The element that would be used to depict a model library on a diagram is a package with the stereotype <<modelLibrary>> 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 3

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.

Question 4

Choose the correct answer

Which technique is typically used to support the automated generation of development artifacts from a SysML model?

ADefine simple structures for artifacts and avoid complex layouts for office documents

BApply stereotypes to model elements to add the metainformation required for the generation process.

CAdapt open-source model transformation tools originally developed for the software engineering discipline

DSysML already includes a concept for model-driven generation of office documents

Answer : B

A common technique for supporting the automated generation of development artifacts from a SysML model is to apply stereotypes to model elements to add the metainformation required for the generation process. Stereotypes can define tagged values that specify additional information about model elements, such as document templates, formatting options, traceability links, etc. These tagged values can be used by model transformation tools or scripts to generate artifacts from the model.

Question 5

Choose the correct answer

What is a common reason for extending SysML with a profile?

ASysML requires the definition of a profile

BA profile adds methodology- and domain-specific concepts to SysML.

CA profile adds user-specific needs to the model in a systems engineering project

DA profile overwrites unwanted SysML concepts and tool-vendor-specific extensions

Answer : B

A profile is a mechanism for extending SysML with additional modeling elements that are not part of the standard language. A profile can add methodology- and domain-specific concepts to SysML, such as stereotypes, tagged values, constraints, etc. These concepts can be used to tailor SysML to specific engineering domains or modeling methods.

Question 6

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 7

Choose the correct answer.

Which versions of the various Architectural Frameworks does UPDM 1.0 officially support?

ADoDAF 1 0 and MODAF 1.2

BDoDAF 1.5, MODAF 1.2. and NAF 3.0

CDoDAF 1 5 and 2.0, and MODAF 1.2

DDoDAF 1 5 and MODAF 1.2

Answer : C

The versions of the various Architectural Frameworks that UPDM 1.0 officially supports are DoDAF 1.5 and 2.0, and MODAF 1.2. UPDM 1.0 provides two sets of profiles: one for DoDAF 1.5 and MODAF 1.2 based on the UPDM 1.1 metamodel, and another for DoDAF 2.0 based on the same metamodel. UPDM 1.0 does not support NAF (NATO Architecture Framework), which is another architectural framework used in the defense domain.
