OOAD Design 46-73

Which statement is true about packages and subsystems?

• A package cannot contain a subsystem.

• A package provides behavior.

• A subsystem provides behavior.

• You use a package when you need to encapsulate behavior.

How many physical nodes should be identified in order to perform the Describe Distribution activity?

• zero nodes only

• one node only

• zero nodes or one node

• more than one node

Supplemental sequence diagram documentation, in the form of notes and scripts, is commonly used for _____. (Choose three.)

• describing required timing between messages

• providing details about conditional behavior

• specifying the attributes for objects that appear in the diagram

• correlating extension points in the use case with specific locations in the sequence diagrams

What is used to describe the process of applying a distribution mechanism during implementation?

• activity diagram

• flowchart

• UML pattern and written steps

• use-case diagram

What does an underlined attribute indicate?

• The attribute is read-only.

• The attribute is derived from other attributes.

• The attribute uniquely identifies instances.

• The attribute is defined at the classifier level instead of the instance level.

With respect to persistence, what are two functions of transactions? (Choose two.)

• ensure that a set of operations is performed either in total, or not at all

• enable a designer to selectively define operations that will be executed with priority when there is a shortage of system resources

• ensure that sets of objects move from one consistent state to another

• simplify design work, so that persistence does not need to be explicitly considered during Use Case Design

• simply design work, by providing standardized approaches for representing persistent objects in UML

What are three purposes of Use Case Design? (Choose three)

• to refine use-case realizations in terms of interactions

• to ensure the completeness of the View of Participating Classes diagrams for each use-case realization

• to refine requirements on the operations of design classes

• to refine requirements on the operations of design subsystems and/or their interfaces

Which is a Use Case Design output artifact?

• analysis classes

• design classes

• interfaces

• the Design Model

Which is an example of an Execution Environment?

• Gigabit network switch

• virtual private network

• J2EE application server

• handheld computer

The purpose of Unify Classes and Subsystems is to ensure _____.

• each subsystem has a corresponding subsystem component

• all classes are assigned to at most one subsystem

• the responsibilities of design elements do not overlap

• each defined interface has a cohesive and coherent API
