What is common practice when integrating software models into SysML system models?
- A. Cross-relationships are defined between a UML software model and a SysML system model
- B. The software is specified with UML in the SysML system model
- C. The software is specified with SysML in the SysML system model.
- D. A model-to-model transformation integrates a UML software model into a SysML system model
Answer: A
Explanation:
Explanation
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. References:

NEW QUESTION # 18
Choose the correct answer
A system engineer is designing an algorithm that governs the behavior of his system-of-interest He is using SysML for modeling system behavior and related allocations, and plans to auto-generate MATLAB code for algorithm execution and testing.
Which modeling approach should the engineer use?
- A. use block constructs to represent the algorithm and its functions, and create part properties to represent the use of the functions in the algorithm
- B. Code generation is outside the scope of SysML. so the system engineer should use UML
- C. use package constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm
- D. use activity constructs to represent the algorithm and its functions, and create actions to represent the use of functions in the algorithm
- E. use block constructs to represent the algorithm, and create use cases for each of the functions used in the algorithm
- F. use activity constructs to represent the algorithm and its functions, and create containment relationships to represent the use of functions in the algorithm
Answer: D
Explanation:
Explanation
This modeling approach should be used by the system engineer because it allows him to capture the behavior of his system-of-interest using SysML activities and actions. An activity is a behavior that specifies the coordination of actions. An action is a behavior that specifies a transformation or processing of data. By using activities and actions, the engineer can model the algorithm and its functions in terms of inputs, outputs, control flows, object flows, parameters, etc. He can also use allocations to relate the activities and actions to other model elements, such as blocks or requirements. This way, he can generate MATLAB code from his SysML model for execution and testing. References:

Choose the correct answer.
What is a best practice to link actions of an activity in a SysML model to a software application described in a UML model?
- A. The actions are moved into the namespace of the UML model
- B. The actions are copied into the UML model using the copy relationship.
- C. The actions are assigned to an activity partition that represents the software application
- D. The actions in the SysML model are called by appropriate CallBehaviorActions in the UML model
Answer: D
Explanation:
Explanation
The best practice to link actions of an activity in a SysML model to a software application described in a UML model is to use CallBehaviorActions in the UML model that call the actions in the SysML model. A CallBehaviorAction is an action that invokes a behavior and provides inputs and outputs. By using CallBehaviorActions, the software application can reuse the behavior defined in the SysML model without having to duplicate or copy it. This also ensures consistency and traceability between the models. References:

NEW QUESTION # 20
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?
- A. create a SysML model that contains only one diagram showing all the core processes and their relationships
- B. create a SysML model for each of the core processes, and manage relationships between processes in a spreadsheet
- C. create a SysML model that contains a package for each of the core processes, and a package for the overall consolidated process and related relationships
- D. create a SysML model for each of the core processes and for each relationship between processes
- E. create 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
Explanation:
Explanation
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. References:

NEW QUESTION # 21
Choose the correct answer.
A modeling team supervisor wishes to force modelers to use particular metamodeling features What must the supervisor do?
- A. "apply" the profile to the model with the {required} keyword applied
- B. "import" the profile to the model with the {required} keyword applied
- C. "import" the profile to the model with the {strict} keyword applied
- D. "apply" the profile to the model
- E. "apply" the profile to the model with the {strict} keyword applied
- F. place the profile in the current namespace with the model
Answer: E
Explanation:
Explanation
To force modelers to use particular metamodeling features, the supervisor must "apply" the profile to the model with the {strict} keyword applied. This keyword indicates that only elements with stereotypes defined in the profile can be created as instances of the extended metaclasses. For example, if a profile defines a stereotype <<quality>> as an extension of Class, then only classes with this stereotype can be created as instances of Class when the profile is applied with the {strict} keyword.

What kind of models can be exchanged using XMI?
- A. instances of MOF models
- B. only UML and SysML models
- C. instances of metamodels that can be described by an XML schema
- D. only UML models including profiles
Answer: A
Explanation:
Explanation
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. References:

What is the key distinction between SysML modeling and MOF modeling?
- A. They both have the same purpose except that MOF modeling is intended for specialized and advanced usage by systems architects
- B. MOF models are intended to be models of modeling constructs SysML models represent real world entities and processes.
- C. MOF models are intended to be strictly models of abstract entities SysML models represent real world entities and processes
- D. MOF models are used for domain-independent modeling SysML models are used for domain-specific modeling.
Answer: B
Explanation:
Explanation
MOF stands for Meta-Object Facility, which is a standard for defining metamodels. Metamodels are models of modeling constructs, such as classes, attributes, associations, etc. SysML stands for Systems Modeling Language, which is a standard for modeling complex systems using diagrams and textual notations. SysML models represent real world entities and processes, such as components, behaviors, requirements, etc. The key distinction between SysML modeling and MOF modeling is that SysML models are instances of a metamodel defined by MOF.

Which aspect of a MBSE-based engineering project falls outside of the scope of AP233?
- A. issue management
- B. slate machines
- C. lifecycle stages
- D. diagrams
Answer: D
Explanation:
Explanation
This aspect of a MBSE-based engineering project falls outside of the scope of AP233 because AP233 does not cover diagrams. AP233 (Application Protocol 233) is a standard that defines an information model for systems engineering. It specifies the concepts and relationships for representing systems engineering data, such as requirements, functions, properties, etc. AP233 does not define any notation or presentation for diagrams, such as SysML diagrams. AP233 only defines the serialization and deserialization of systems engineering data using XMI (XML Metadata Interchange) format. Therefore, AP233 does not address how to exchange diagrams between tools or how to visualize diagrams in different tools. References:

Given the following diagram fragment:
Which criterion indicates that a decision node construct such as this is well-formed?
- A. Taken together, the guards cover all possibilities and are mutually exclusive.
- B. Each guard legal can be evaluated without changing the state of any item referenced by the corresponding activity or action Ai
- C. No activity Ai will negate the corresponding guard [gi]
- D. The guards are understandable by stakeholders in the development effort.
Answer: A
Explanation:
Explanation
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.
NEW QUESTION # 27
Choose the correct answer
Which relationship is likely to be most heavily used during requirements analysis?
- A. copy
- B. refine
- C. verify
- D. satisfy
Answer: B
Explanation:
Explanation
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.

NEW QUESTION # 29
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 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
- B. 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
- C. define a package that contains a note for each type of module in X. and anchor notes to the blocks in the design model
- D. 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
- E. 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
Answer: A
Explanation:
Explanation
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

What is a common rationale for defining and applying a profile to a SysML model?
- A. The profile adds appropriate metainformation to the model to allow automated system analysis
- B. The profile enables separate views of the model for the different stakeholder concerns.
- C. The profile extends the model with reusable elements, e.g. units.
- D. The profile makes the model suitable for a modeling tool
Answer: C
Explanation:
Explanation
A common rationale for defining and applying a profile to a SysML model is that the profile extends the model with reusable elements, such as units, quantities, value types, etc. These elements can be defined in a model library and imported into other models by applying the profile. This way, the profile enables consistent and standardized modeling of properties and parameters of blocks and constraints. References:

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?
- A. access to a large model library and legacy code base
- B. direct support for quickly characterizing and prototyping services
- C. the ability to rapidly prototype the user interface
- D. the ability to rapidly explore required system functionality
- E. a robust ontology for characterizing complex systems
Answer: D
Explanation:
Explanation
The most important factor that the engineer should consider in selecting a system development methodology for an unprecedented system with unclear or incomplete user and system requirements is the ability to rapidly explore required system functionality. The ability to rapidly explore required system functionality means that the system development methodology can support the elicitation, analysis, validation and verification of the user and system requirements through various techniques, such as use cases, scenarios, prototypes, simulations and tests. The ability to rapidly explore required system functionality can help reduce the uncertainty and ambiguity of the requirements and increase the confidence and satisfaction of the stakeholders. The ability to rapidly prototype the user interface is a less important factor that may not be relevant or applicable to all systems or projects. Access to a large model library and legacy code base is a less important factor that may not be available or suitable for an unprecedented system. A robust ontology for characterizing complex systems is a less important factor that may not be necessary or sufficient for defining the requirements. Direct support for quickly characterizing and prototyping services is a less important factor that may not be relevant or applicable to all systems or projects.
