OMG OMG-OCUP2-ADV300 Dumps Questions Answers

In the context of UML 2.0 and the specifications around Decision Nodes, option C is the correct choice. According to the UML 2.5 specification, when a Decision Node has an incoming control flow and adecisionInput, thedecisionInputmust have a single input parameter (in Parameter). This ensures that the decision node can evaluate the decision input using the value passed through the incoming control flow. This mechanism is crucial for decision-making processes within activity diagrams where decisions are made based on dynamic data provided at runtime.

• UML 2.5 Specification: The specification details the properties and behaviors of Decision Nodes within activity diagrams, particularly emphasizing how decision inputs and their parameters are handled.

The reason for fUML to be compact is to facilitate the definition of clear semantics. A smaller, more focused subset of UML allows for a more precise and unambiguous specification of the execution semantics. This clarity is essential for ensuring that models are executed consistently and as intended across different tools and platforms2. The compact nature of fUML helps inachieving this goal by limiting the scope to the essential elements necessary for execution, thereby reducing complexity and potential for misinterpretation.

Protocol State Machines in UML are used to specify the allowable protocol transitions that can be observed in the instances of a classifier. The interpretations that can be defined for protocol state machines are:

• A.Behavioral and protocol are not specific types of interpretations but rather describe aspects of state machines in general.
• B.Declarative and procedural describe styles or approaches to programming or specification, not specific to UML state machine interpretations.
• C.Declarative and executable is the correct answer. Declarative interpretations specify the allowed sequences of events in a state machine, while executable interpretations are concerned with the actual implementation that can be executed by a machine.
• D.Executable and non-executable are distinctions but not specifically pertaining to protocol state machine interpretations alone.
