• Question 1:

  Choose the correct answer

  What kind of models can be exchanged using XMI?

  A. only UML models including profiles
  B. only UML and SysML models
  C. instances of MOF models
  D. instances of metamodels that can be described by an XML schema
  C. instances of MOF models

  ---

  Explanation/Reference:

  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.

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

  A. It allows users to express all the views in the architecture using only SysML elements
  B. It allows users to bring SysML elements into the architecture to enhance the hand-off between Systems of Systems and Systems.
  C. SysML elements are only used in the Systems view to enhance the hand-off process between Systems of Systems and Systems.
  D. There is no benefit jas SysML is not used in compliance level 1
  B. It allows users to bring SysML elements into the architecture to enhance the hand-off between Systems of Systems and Systems.

  ---

  Explanation/Reference:

  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 3:

  Choose the correct answer-.

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

  A. a trade study
  B. an objective analysis
  C. operational research
  D. a requirements analysts
  A. a trade study

  ---

  Explanation/Reference:

  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 4:

  Choose the correct answer.

  Given the following diagram fragment:

  

  Which criterion indicates that a decision node construct such as this is well-formed?

  A. No activity Ai will negate the corresponding guard [gi]
  B. Taken together, the guards cover all possibilities and are mutually exclusive.
  C. Each guard legal can be evaluated without changing the state of any item referenced by the corresponding activity or action Ai
  D. The guards are understandable by stakeholders in the development effort.
  B. Taken together, the guards cover all possibilities and are mutually exclusive.

  ---

  Explanation/Reference:

  A decision node is a construct in SysML that represents a branching point in an activity diagram where alternative paths are chosen based on some conditions. The guards are expressions that specify the conditions for each outgoing edge from the decision node. A criterion that indicates that a decision node construct is well-formed is that the guards cover all possibilities and are mutually exclusive, meaning that for any input value, exactly one guard evaluates to true and all others evaluate to false. This ensures that there is no ambiguity or conflict in choosing the next path in the activity.

• Question 5:

  Choose the coned answer

  What is the best way to ensure that a shared model has consistently-represented elements and diagrams?

  A. Implementation of standard libraries
  B. modeling conventions and standards
  C. packages that map one-for-one to components
  D. domain stereotypes maintained in a configuration control system
  B. modeling conventions and standards

  ---

  Explanation/Reference:

  The best way to ensure that a shared model has consistently-represented elements and diagrams is to use modeling conventions and standards. Modeling conventions and standards are rules and guidelines that define how the model elements and diagrams should be named, defined, structured, formatted and documented. Modeling conventions and standards can help improve the clarity, consistency and quality of the model and facilitate the communication and collaboration among the modelers and stakeholders. Implementation of standard libraries is a good way to ensure that a shared model has reusable and interoperable elements and diagrams, but it may not ensure their consistent representation. Packages that map one-for-one to components is a good way to ensure that a shared model has modular and traceableelements and diagrams, but it may not ensure their consistent representation. Domain stereotypes maintained in a configuration control system is a good way to ensure that a shared model has customized and controlled elements and diagrams, but it may not ensure their consistent representation.

• Question 6:

  Choose the correct answer

  A large company uses SysML to design energy systems, and plans to use a specialized proprietary analysis tool (X) for evaluating and comparing the cost, performance, and reliability of energy system alternatives The engineers at the

  company want to automatically create analysis models in X from design models in SysML.

  The achieve this, they will use the following process:

  (1)

  Specify the appropriate module in X10 be used for each block m the SysML design model.

  (2)

  Write scripts that use these mappings to automatically create analysis models in X Which approach is most flexible when enabling this automation?

  A. define a package that contains a note for each type of module in X. and anchor notes to the blocks in the design model
  B. define a profile that contains a stereotype for each type of module m X. and assign the stereotype to the blocks in lite design model
  C. define a profile that contains a tag for each type of X in the tool, and assign the stereotype to the blocks in the design model
  D. define a profile that contains a stereotype with a tag that can store the name of the module in X. apply the stereotype to the blocks in the design model, and populate the tag
  E. define a package that contains a block for each type of module m X (e g module_1 block) and create a dependency relationship from the module block to the blocks in the design model
  D. define a profile that contains a stereotype with a tag that can store the name of the module in X. apply the stereotype to the blocks in the design model, and populate the tag

  ---

  Explanation/Reference:

  A profile is a mechanism for customizing SysML for a specific domain or purpose. A stereotype is a way of extending or modifying the semantics of a SysML element. A tag is an attribute of a stereotype that can store additional information. By defining a profile that contains a stereotype with a tag that can store the name of the module in X, the engineers can easily map the blocks in the design model to the corresponding modules in X, and use scripts to automate the creation of analysis models. This approach is more flexible than using notes, dependencies, or predefined tags, because it allows for more control and consistency over the mapping proces

• Question 7:

  Choose the correct answer

  How does SysML support systems engineering methodologies?

  A. The generalization mechanism enables fitting of SysML to a methodology
  B. The stereotype and profile mechanisms enable lilting of SysML to a methodology.
  C. SysML can only support a systems engineering methodology if it is used at the starting point of the project
  D. SysML does not support system engineering methodologies, as it is a language
  B. The stereotype and profile mechanisms enable lilting of SysML to a methodology.

  ---

  Explanation/Reference:

  SysML is a general-purpose modeling language for systems engineering that can support various systems engineering methodologies. The stereotype and profile mechanisms are features of SysML that enable customizing and extending the language for a specific domain or purpose. By using stereotypes and profiles, SysML can be adapted to fit different methodologies and conventions without changing the core language semantics

• Question 8:

  Choose the correct answer

  In addition to selecting the methodology activities to be performed, what other tailoring does the systems modeling team need to consider when defining the project methodology?

  A. which activities will interact with external systems
  B. which kind of diagrams will be used to create the domain model
  C. which artifacts need to be produced when executing the tailored activities
  D. which requirements will be allocated to the specialty engineering activities
  C. which artifacts need to be produced when executing the tailored activities

  ---

  Explanation/Reference:

  An artifact is a tangible or intangible product or outcome of an activity or process. Examples of artifacts include models, diagrams, documents, reports, etc. When defining the project methodology, the systems modeling team needs to consider which artifacts need to be produced when executing the tailored activities, because this determines what information needs to be captured, communicated, and delivered throughout the project lifecycle. The artifacts should be aligned with the project objectives, scope, deliverables, and quality standards

• Question 9:

  Choose the correct answer

  Which OMG specifications does UPDM use at L1?

  A. UMLandSysML
  B. UML. SysML. and BPMN
  C. UML, SysML and MARTE
  D. UML, SysML and SOAML
  A. UMLandSysML

  ---

  Explanation/Reference:

  The OMG specifications that UPDM uses at L1 are UML and SysML. L1 is the level of abstraction that defines the core concepts of UPDM without any implementation details. It is based on a Domain Metamodel that captures the common elements of DoDAF and MODAF. The Domain Metamodel is mapped to UML and SysML concepts using a Platform Independent Model (PIM). UML and SysML provide the basic metaclasses and diagrams that UPDM uses to represent architectures.

• Question 10:

  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
  D. function to structure

  ---

  Explanation/Reference:

  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
