Question 1

Choose the correct answer Where may tagged values be defined?

Aonly as attributes of classifiers

Bonly as attributes of stereotypes

Con any model element in a profile

Don any model element

Answer : B

Tagged values can be defined only as attributes of stereotypes. A tagged value is an extension of a model element with additional information that is not part of its standard properties. A tagged value is defined by an attribute of a stereotype that is applied to the model element. The attribute specifies the name and type of the tagged value.

Question 2

Choose the correct answer.

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

AThe software is specified with UML in the SysML system model

BThe software is specified with SysML in the SysML system model.

CCross-relationships are defined between a UML software model and a SysML system model

DA model-to-model transformation integrates a UML software model into a SysML system model

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.

Question 3

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.

Question 4

Choose the correct answer

A stereotype is defined in a profile This stereotype has two properties whose types were already defined in the model

What must be done to reuse their type definitions?

AThe package defining the types needs to apply the profile.

BThe package defining the types needs to import the profile

CThe profile needs to apply the package where these types are defined.

DThe profile needs to import the package where these types are defined.

Answer : D

To reuse the type definitions of the properties of a stereotype, the profile needs to import the package where these types are defined. An import relationship indicates that the elements in one package can be referenced by another package without a qualified name. By importing the package with the types, the profile can use them as attributes of the stereotype without having to redefine them.

Question 5

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 6

Choose the correct answer

Which statement about working in UPDM compliance level 1 is true?

AIt allows users to express all the views in the architecture using only SysML elements

BIt allows users to bring SysML elements into the architecture to enhance the hand-off between Systems of Systems and Systems.

CSysML elements are only used in the Systems view to enhance the hand-off process between Systems of Systems and Systems.

DThere is no benefit jas SysML is not used in compliance level 1

Answer : B

Working in UPDM compliance level 1 allows users to bring SysML elements into the architecture to enhance the hand-off between Systems of Systems and Systems. Compliance level 1 is based on UML and SysML concepts and provides integration with system modeling using SysML. Users can use SysML elements, such as blocks, ports, connectors, parametrics, etc., to model system components and their interactions in more detail and precision than using UML elements alone. This can facilitate the transition from architecture modeling to system design and analysis.

Question 7

Choose the correct answer

What are two cross-cutting mechanisms within SysML that can be used to establish traceability between the systems model and a UML software model?

Apackages and parametrics

Bprofiles and stereolypes

Callocations and stereotypes

Drequirement relationships and allocations

Answer : C

Two cross-cutting mechanisms within SysML that can be used to establish traceability between the systems model and a UML software model are allocations and stereotypes. Allocations are dependencies that indicate a relationship between elements in different models or domains. Stereotypes are extensions of existing metaclasses that add additional information or semantics to model elements. By using allocations and stereotypes, different aspects of the systems model and the software model can be linked and traced.
