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.

The compiled model resulting from the Action Language for Foundational UML (fUML) must have the equivalent effect as a model resulting from the mapping to fUML. In other words, the compiled model should behave in the same way as if it were directly executed using the fUML execution semantics

The answer is B, "The transmitted object may be copied and the object identity may be changed." When an object is sent from one action to another, it is not always guaranteed that the identity of the object will be preserved. It depends on the semantics of the transmission, which may allow for object copying, and hence the object identity may change during the process.

• UML 2.5 Specification: The section on send actions within activity diagrams describes the behavior of object flows, including transmission semantics regarding object identity and copying.

To represent specific hardware environments in a deployment model, a modeler should create a UML profile that includes the necessary hardware stereotypes with applicable details. A profile allows the modeler to extend the standard UML metamodel to include domain-specific elements that can be applied to deployment models. These stereotypes can represent different types of hardware components and their attributes, which can then be used to model the physical aspects of the deployment environment. The creation and application of profiles are supported by the UML 2.x Superstructure Specification, which details how to tailor UML to particular domains or platforms using profiles.
