1.

What must include all of the information needed to construct a system and to put it into operation?

Platform Viewpoint Implementation Platform Specific Model

2.

The UML Profile for Schedulability, Performance and Time (SPT) does NOT provide facilities for ______.

capturing performance requirements within the design context providing accurate end-to-end latencies of the modeled system presenting performance results computed by modeling tools or found in testing associating performance-related QoS characteristics with selected elements of a UML model

3.

Which statement is true when domains are modeled using the Profile for SPT?

In performance-related models, each scenario is executed by a job class or user class which is identical to other UML Classes. Performance measures for a system include only the combined waiting times, execution demands and response time for the resources. Scenario steps are the elements of scenarios, and are joined in a sequence, with predecessor-successor relationships that may include forks, joins, and loops. Resources are modeled as servers with passive resources being the usual servers in performance models that are acquired and released during scenarios, andhave holding times.

4.

Which is an attribute of RTCclient?

host capacity clientPriority clientScenario

5.

Which statement is true about RT CORBA connections?

Priorities must be set by the clients. All connections must be shared by individual clients. Scheduling policy mechanisms are explicitly called out by the standard. Priority-based handling of requests can be established for multiple shared connections.

6.

From the Domain Viewpoint as defined in the UML Profile for SPT, which statement is true about RT CORBAs extensions to standard CORBA?

They provide for gaining knowledge of absolute priorities of activities in distributed environments. They provide for a data centric (i.e. ordered packet) capability in CORBA in homogeneous environments. They provide a framework for predictable end-to-end execution times in distributed and heterogeneous environments. They provide a mechanism to support but NOT guarantee that deadlines are met in distributed and embedded environments.

7.

What is the purpose of the RT CORBA Application extensions?

to provide additional interoperability timing mechanisms to constitute a sub-profile of the performance sub-profile to facilitate the timing analysis of RT CORBA applications to extend the schedulability framework as expressed in UML models

8.

Which statement is true about the viewpoints defined in the UML Profile for SPT?

The UML Viewpoint uses scenarios which are most directly modeled using only activity graphs. The Domain Viewpoint uses scenarios to define response paths whose end points are externally visible. The Collaboration Viewpoint uses scenarios that are mapped onto specific instances in order to define end point latencies. The Harel State Viewpoint uses state model diagrams to capture timely behaviors of system transactions across the various processing nodes.

9.

Which QoS characteristic deals with the accuracy of results?

Integrity Reliability Coherence Dependability

10.

What is the name of the stereotype in the encapsulating class of the following diagram?
