Pearson OMG-OCUP2-ADV300 New Attempt

"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.

Protocol Conformance in UML is a relationship between protocol state machines that ensures consistency in behavior inheritance:

• A.Incorrect as it describes a general-to-inherited relationship, which is not the focus of protocol conformance.
• B.Incorrect, as it describes a relationship the wrong way around (general to nested).
• C.Correct. Protocol Conformance ensures that a specific Protocol State Machine conforms to the rules and constraints specified by a redefined, more general Protocol State Machine.
• D.Incorrect, because it generally describes conformance but does not specifically focus on the relationship between specific and general state machines in the context of protocols.

References:

• UML Specification: Protocol State Machines section.
• Specifics of protocol conformance are detailed under state machine and classifier behaviors in the UML 2.5 Documentation.

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.

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.

• UML Specification, Section on StateMachines
• StateMachine Redefinition is further elaborated in UML 2.5 Documentation under the Behavior StateMachines sections.
