Answer : C

In fUML (Foundational UML), an execution model must be modeled as an Activity.fUML is a subset of UML that includes the ability to model behavior using UML activities, which are composed of a rich set of primitive actions1.Activities in fUML represent the executable aspects of a model and define the flow of control and data2. They are the primary means for specifying the detailed procedural logic of the behavior of a system within fUML.

Answer : B

In addition to ObjectFlow, which is used to denote the flow of objects between activities in a UML Activity diagram, data movement can also be facilitated through:

A . Pin is a point on a node that is used to accept or provide objects or data, but does not move data by itself.

B . Correct. Variables can be used to hold and move data within an activity, facilitating state maintenance or transitions between different actions.

C . Property, while it holds data, typically pertains to classes or components, not activities.

D . ControlFlow dictates the order of execution but does not inherently move data.

UML Specification: Activity Diagrams section.

Details on how data can be managed within activities can be explored in the UML 2.5 Documentation, particularly under Activity and Object Nodes.

Answer : C

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.

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.

Answer : C

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.

UML Specification: Protocol State Machines section.

Specifics of protocol conformance are detailed under state machine and classifier behaviors in the UML 2.5 Documentation.

Answer : C

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.

UML Specification: State Machines chapter, particularly sections on protocol state machines.

Further details can be found in the UML 2.5 Documentation discussing the differences between different state machine interpretations.

Answer : C

The provided diagram fragment shows what appears to be Components or Classes with dashed arrows pointing towards them. Typically in UML, a dashed arrow with an unfilled arrowhead represents a Realization relationship, which is used to show that an element (such as an interface) is realized by another element (such as a class or component). However, when we are talking about Classes like 'EventRegistration,' 'MessagePacket,' 'Attendee,' and 'Session' which seem to share a common nature or purpose with 'EmailServices,' these relationships are more appropriately modeled as Generalizations, indicating that they inherit from a common superclass or implement a common interface. Realizations are typically not used in this context. Hence, the dashed arrows in the diagram should be solid lines representing Generalization, not Realization. This answer aligns with the UML 2.x Superstructure Specification, which provides guidance on the usage of Realization and Generalization relationships in class diagrams.

Answer : D

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.
