NEW QUESTION # 16
Choose the correct answer:
Which subclasses ofClassifiers can be parameterized and used as Template Parameters?
- A. Class. Component. Interface, but not Signal
- B. all subclasses of Classifier e.g. Class. Component. Datatype. Interface. Signal
- C. Activity. Interaction, State Machine, but not Collaboration
- D. Signal. Use Case, Component, but not Datatype
Answer: B
Explanation:
In UML, a template is a parameterizable element, and the parameters for a template are typically classes or other classifiers. According to the UML 2.x Superstructure Specification, all subclasses of Classifier can potentially be used as template parameters. This includes classes, components, datatypes, interfaces, signals, and more. The specification provides the flexibility to define template parameters that are specialized types, allowing for powerful and reusable designs. The ability to parameterize these elements is foundational to creating generic and reusable model elements, which is a core capability of the UML's templating mechanism.
NEW QUESTION # 17
Choose the correct answer:
What is the main purpose of the concept of Extent in MOF?
- A. To provide a context in which an Element can be identified independently from any value in the Element.
- B. To define a set of Tags that represent information to be associated by any number of model Elements.
- C. To provide an extension mechanism to dynamically annotate model Elements with additional information.
- D. To allow an Element to access its meta class in order to obtain a reflective description of that Element.
Answer: B
Explanation:
The concept of Extent in MOF serves the purpose of defining a set of Tags that can be associated with any number of model elements. These tags provide additional information or metadata about the elements. Extent allows you to annotate model elements with relevant information beyond their intrinsic properties. It provides a context for identifying and managing these annotations independently from the element's actual values.
NEW QUESTION # 18
Choose the correct answer:
Can State Machine Events have Features?
- A. Yes. they can. but only when the modeled Events also extend Classifier.
- B. Yes. they can
- C. No. they can not. because State Machine Events are not Classifiers.
- D. No. they can not. because UML State Machines do not have an Event concept.
Answer: C
Explanation:
State Machine Events in UML are triggers for transitions and do not classify as objects or classifiers; thus they do not inherently have features:
* A.Incorrect, because State Machine Events are not treated as classifiers with features.
* B.Incorrect, though it hints at an extended use case, State Machine Events do not extend classifiers in standard UML usage.
* C.Correct, State Machine Events are not Classifiers and therefore cannot have features such as properties or operations.
* D.Incorrect, because UML State Machines certainly have an Event concept, but these Events are not classified as having features.
References:
* UML Specification: State Machine chapter, specifically sections discussing the nature of events and triggers.
* Further insights can be found in the event and trigger management sections of the UML 2.5 Documentation.
NEW QUESTION # 19
Choose the correct answer:
Which statement is correct about redefinition of simple States?
- A. A simple State can be redefined by excluding it in a redefined StateMachine.
- B. A simple State can be redefined as a composite State with one or more Regions.
- C. A simple State cannot be redefined
- D. State Redefinition is not a UML capability.
Answer: A
Explanation:
In UML, a simple State can indeed be redefined, but the specifics of how it is redefined matter:
* Ais incorrect as redefinition of States, including simple States, is permitted.
* Bis correct. A simple State can be effectively removed or altered through redefinition in a derived StateMachine, which could include changing its type or characteristics.
* Csuggests that a simple State can be turned into a composite State. While theoretically possible in the context of redefinition, this option might be considered a significant alteration that could be misleading without additional context.
* Dis incorrect; UML does support State Redefinition.
References:
* UML Specification, particularly the sections on Redefinition and StateMachines.
* Detailed rules on state redefinition are outlined in the UML 2.5 Documentation, specifically under StateMachine specializations.
NEW QUESTION # 20
Choose the correct answer: Consider the following definition:
Which statement is correct about elements referred to in the illustration?
- A. wheels is a property of Vehicle.
- B. mycar is a classifier.
- C. frontleft must have a void type.
- D. rear is a property of Wheel.
Answer: A
Explanation:
In the diagram, "mycarVehicle" represents a class that likely encapsulates the concept of a vehicle within the system being modeled. The elements within "mycarVehicle" are properties that represent different parts of the car. The term "wheels" is not explicitly shown in the diagram, but based on UML conventions and the context provided, it would be a property of the Vehicle class. This property would likely be associated with the
"frontleft" and "frontrightwheels" parts of the car. In UML, properties represent structural features of a class that hold data values or references to other objects. The correctness of this answer is consistent with the principles found in the UML 2.x Superstructure Specification regarding the structural features of classes.
NEW QUESTION # 21
Choose the correct answer:
Consider the following diagram:
What kind of model element is chentNo?
- A. a qualifier of the Association
- B. a Property defined by Association and owned by the Class Examinee
- C. a Property defined by Association and owned by the Class ExamCompany
- D. a Port of Class ExamCompany
Answer: A
Explanation:
In the context of the diagram, "clientNo" is placed next to the association line between "ExamCompany" and
"Examinee," which indicates that "clientNo" is a qualifier of the association. In UML, a qualifier is used to refine the association between two classes by providing a way to access linked objects based on some attribute value. The qualifier essentially acts as a key in an associative array or map, allowing access to instances of the associated class. In this case, "clientNo" is likely used to uniquely identify examinees associated with an exam company. This use of qualifiers is detailed in the UML 2.x Superstructure Specification, which describes how qualifiers can be used to specify refined access to linked objects within an association.
NEW QUESTION # 22
Choose the correct answer:
What must a modeler do to use an Action that coordinates other Actions?
- A. use the standard Action and add desired tag values
- B. use one of the StructuredActivityNodes in UML
- C. extend Behavior and add the desired Actions
- D. extend Action and specify the constraints to be relaxed or removed
Answer: B
Explanation:
To orchestrate multiple actions within UML, a modeler should use StructuredActivityNodes:
* A.Extending Behavior and adding desired Actions is not specifically about coordinating multiple actions; it's about defining new behaviors.
* B.Correct. StructuredActivityNodes are a part of UML that provides a mechanism to group a set of actions together and manage the data flows between them, thus coordinating the actions.
* C.Using the standard Action and adding desired tag values does not inherently coordinate actions.
* D.Extending Action and specifying constraints to be relaxed or removed does not directly relate to coordinating other actions.
References:
* UML Specification: Activities section, which describes the use of StructuredActivityNodes.
* The use of StructuredActivityNodes for coordinating actions is elaborated in the UML 2.5 Documentation under Activity Diagrams.
NEW QUESTION # 23
Choose the correct answer: Which construct specifies all possible valid traces?
- A. generalized ordering
- B. alt combined fragment
- C. assert combined fragment
- D. opt combined fragment
Answer: C
Explanation:
In UML, combined fragments are used to model complex sequence flows by grouping a set of interactions together. Each type of combined fragment has a different semantic use.
The 'assert' combined fragment specifies that the sequence of events inside the fragment must occur exactly as shown, with no deviations or alternatives. This implies that all possible valid traces in the sequence are exactly those specified within the 'assert' fragment; there are no optional or alternative flows.
References include:
* UML 2.5 Specification (formal/2017-12-05), specifically the section on Combined Fragments and their semantics.
* UML Sequence Diagrams: Overview of Graphical Notation, which discusses the purpose of different combined fragments.
NEW QUESTION # 24
Choose the correct answer:
Which statement is correct about StateMachme Redefinition?
- A. When a modeler corrects typographical errors or removes inappropriate States in their StateMachine, they are redefining that StateMachine.
- B. StateMachine Redefinition is a necessary capability in UML because UML allows modelers to specialize Classifiers and their Behavior definitions.
- C. UML has no concept or discussion of StateMachine Redefinition.
- D. StateMachine Redefinition is the act of altering an existing StateMachine to support new States or new Events.
Answer: B
Explanation:
StateMachine Redefinition in UML allows for the specialization of a StateMachine by a derived Classifier.
This is crucial as it ties into the broader capability of UML to specialize behaviors and classifiers:
* Ais incorrect; UML does discuss StateMachine Redefinition.
* Bdescribes one aspect of redefinition but is too narrow as it omits that redefinition can also redefine transitions and internal behaviors, not just states or events.
* Cdescribes more of an error correction or revision process, which is not specifically what StateMachine Redefinition is about.
* Dcaptures the essence of StateMachine Redefinition, emphasizing that it is a necessary extension of UML's capabilities to allow for specialization and refinement of classifiers and their behaviors.
References:
* UML Specification, Section on StateMachines
* StateMachine Redefinition is further elaborated in UML 2.5 Documentation under the Behavior StateMachines sections.
NEW QUESTION # 25
Choose the correct answer:
Consider the following diagram fragment:
What is "QueryCustomerFromParcel"?
- A. A Behavior element, for example, an Activity. State Machine, or OpaqueBehavior.
- B. A SQL query
- C. An OCL expression.
- D. An Action with a reference to a transformation behavior.
Answer: A
Explanation:
"QueryCustomerFromParcel" is annotated with the «transformation» stereotype, which indicates that it is a behavior element that specifies how to convert input objects into output objects. Therefore, the answer is D, a Behavior element, for example, an Activity, State Machine, or OpaqueBehavior. In UML, the
«transformation» stereotype is applied to specify that an action or activity is responsible for transforming an input (in this case, "Parcel") into an output ("Customer"), typically by employing a specific behavior element.
References:
* UML 2.5 Specification: Section on Object Flows describes how transformations can be used within activity diagrams to turn inputs into outputs using behavior elements.
NEW QUESTION # 26
Choose the correct answer:
Where does UML explicitly intend String Expression elements to be used?
- A. as (he ValueSpecifications for the nameExpressions of ParameterableElements within Template specifications
- B. whenever an OpaqueExpression form of a ValueSpecification needs to specify an expression that operates on String instances
- C. as the model the author chooses for the specification of custom dynamically-generated names for any NamedElement
- D. The specification has no metaclass StnngExpression and so no use of StringExpression is explicitly intended.
Answer: D
Explanation:
In UML, ValueSpecifications are used to specify the value of an element. The UML 2 Specification does not define a metaclass named StringExpression. Instead, it provides a metaclass named OpaqueExpression, which can be used when an expression is written in a language that is not directly interpretable by the model. Since there is no metaclass called StringExpression in the UML 2 Specification, there is no explicitly intended use for it within the UML metamodel. The absence of this metaclass suggests that any use of a concept called
"StringExpression" would not conform to standard UML 2 practices and would likely be part of an extension or profile, not the core UML metamodel.
NEW QUESTION # 27
Choose the correct answer:
What is the difference between a ValueSpecificattonActlon and a CreateObjectAction?
- A. A ValueSpecificationAction cannot produce instances of Classifiers, but a CreateObjectAction only produces instances of Classifiers
- B. When an InstanceValue is produced by a CreateObjectAction. the Structural Features can be assigned values, but when an InstanceValue is produced by a ValueSpecificationAction, the Structural Features have no values.
- C. When an InstanceValue is produced by a ValueSpecificationAction, the Structural Features can be assigned values, but when an InstanceValue is produced by a CreateObjectAction, the Structural Features have no values.
- D. There is no difference between the possible results of the CreateObjectAction and the ValueSpecificationAction
Answer: A
Explanation:
The difference between ValueSpecificationAction and CreateObjectAction in UML is fundamental to the kinds of results they produce:
* A.Incorrect, as there is a fundamental difference between the outputs of these two actions.
* B.Correct. A ValueSpecificationAction evaluates to a value but does not produce instances of Classifiers, whereas a CreateObjectAction is specifically designed to instantiate classifiers.
* C.Incorrect, because it reverses the capabilities of the two actions.
* D.Also incorrect, because it provides the wrong association of features with actions.
References:
* UML Specification: Action section, where both ValueSpecificationAction and CreateObjectAction are defined.
* Further clarifications on these actions are provided in the UML 2.5 Documentation, especially in parts discussing Actions and Activities.
NEW QUESTION # 28
Choose Ihe correct answer:
Which statement is true about fUML?
- A. All constructs of fUML are executable
- B. fUML includes constructs widely used in both UML models and platform languages.
- C. fUML is designed primarily to express static semantics.
- D. The semantics of Interactions are expressed in fUML
Answer: A
Explanation:
fUML (Foundational UML) is a subset of the standard Unified Modeling Language (UML) that includes standard, precise execution semantics. This subset encompasses typical structural modeling constructs of UML such as classes, associations, data types, and enumerations, as well as the ability to model behavior using UML activities composed from a set of primitive actions. Therefore, a model constructed in fUML is executable in the same sense as a program in a traditional programming language, but with the level of abstraction and richness of expression of a modeling language2.
NEW QUESTION # 29
Choose the correct answer:
Which interpretation is valid when NamedElement A is the Supplier in a specialized Dependency having NamedElement B as the Client, and a Comment indicates that A and B participate in a transformation?
- A. A and B are part of an economic system where A consumes what B transforms.
- B. A is the transformation Realization of B.
- C. B is the transformation Realization of A.
- D. A depends on B.
Answer: D
Explanation:
In UML, a Dependency is a relationship that signifies that one NamedElement, the client, depends on another NamedElement, the supplier, meaning that a change in the supplier could affect the client. If NamedElement A is the supplier and NamedElement B is the client in a Dependency relationship, and there is a Comment indicating that both participate in a transformation, the interpretation is that B (the client) depends on A (the supplier) for that transformation. The comment does not necessarily change the nature of the Dependency relationship; it simply adds additional information about the nature of their interaction. A transformation could mean that B transforms A's supplied element in some way, but in terms of UML Dependency relationships,it would still be interpreted as "A depends on B" or "B requires A for its transformation". This interpretation aligns with the UML 2.x Infrastructure and Superstructure specifications, which explain Dependencies and their meanings within the UML metamodel.
NEW QUESTION # 30
Choose the correct answer:
What happens when an exception is raised by an Action within an Activity that has been invoked asynchronously?
- A. The catching exception handler has exactly one output pin.
- B. The exception is lost if there is no matching handler within the Activity.
- C. The exception is propagated to the caller
- D. That kind of exception cannot be handled.
Answer: B
Explanation:
For asynchronous invocations in UML, when an exception is thrown and there is no matching exception handler within the activity, the exception is effectively lost because there is no direct mechanism to propagate it back to the caller. This reflects the nature of asynchronous communication where the calling process does not wait for the completion of the called process and, thus, may not be designed to handle exceptions that occur during the called process.
References:
* UML 2.5 Specification: The UML specification describes the behavior of actions within activities and how exceptions are handled, or not handled, in the case of asynchronous calls. It specifically states that for asynchronous calls, the exception is not propagated back to the caller as there is no return flow defined for such invocations.
