OMG-OCUP2-ADV300 Dumps With Exact Questions and Answers

In UML Sequence Diagrams, a "neg" (negative) combined fragment is used to specify invalid or forbidden interactions. Therefore:

• A.Incorrect, because a "neg" fragment defines an invalid interaction, so following it by normal positive constructs does not affect its interpretation of invalidity.
• B.Incorrect, as nesting a "neg" fragment within another "neg" fragment does not inherently result in valid traces.
• C.Correct. Normal positive constructs followed by a "neg" fragment define some sequences of interactions as invalid, which is the intended use of the "neg" fragment.
• D.Incorrect, because an "assert" fragment is used to specify required interactions, and containing a "neg" fragment within it does not make the invalid traces valid.

• The negative combined fragment and its semantics are discussed in the UML 2.5 Documentation, under the Sequence Diagrams and Combined Fragments sections.

The UML sequence diagrams provided do not offer enough information to definitively determine the order of event occurrences. Sequence diagrams are used to show how objects interact in a given scenario, particularly the order of messages exchanged between objects. However, without a clear indication of the sequence or additional context, it’s impossible to ascertain which event occurs last.

In UML 2.x, sequence diagrams can be interconnected, but the execution order across separate diagrams is not inherently defined unless explicitly specified. Therefore, based on the information given, the answer is D, as we cannot uniquely determine the last event occurrence without additional details.

A FunctionBehavior in UML is a specialized form of behavior that specifies a function that, when executed, yields results influenced only by its input arguments and its internal attributes, without any side effects (e.g., altering global variables or I/O operations). This makes it stateless. Among the options provided:

• Ainvolves I/O operations which are not covered under FunctionBehavior as it implies side effects.
• Bdeals with environmental inputs and actuator control, not just function computation.
• Ccould be considered but implies a state change which again might involve side effects, depending on the implementation.
• Dpurely involves calculation based on input parameters, which fits the definition of FunctionBehavior perfectly, as it is a stateless computation.
• Eis incorrect because UML indeed includes the concept of FunctionBehavior.
