Test to evaluate UML 2.5 basic structure knowledge.

1 / 14

What is not a purpose of a port owned by a classifier?

Serves as an end point for connectors

Hides the internals of that classifier from other classifier

Provides a distinct point of interaction between the classifier and its environment

Specifies an association to the classifier

2 / 14

What kind of relationship is an extension in UML 2.0?

Generalization

Dependency

Association

Reification

3 / 14

What is NOT true about roles and role bindings?

A role binding is an association

A role binding maps a connectable element to a role in a collaboration occurrence

The same object may play roles in multiple collaborations

A role typed by an interface specifies a sety of features required by a participant in a collaboration

The same connectable element may be bound to a multiple roles in a single collaboration occurrence

4 / 14

Which list contains only connectable elements?

behavior - connector end - port

behavior - port - property

port - connector end

connector end - port - part

property - port - parameter

5 / 14

To what does an internal structure of a class refer?

The decomposition of that class in terms of interconnected parts

The set of structural features of that class

The inheritance structure of that class

The set of nested classifiers of that class

6 / 14

What is a Use Case a kind of?

StructuredClassifier

BehavioredClassifier

NamedElement

PackageableElement

7 / 14

Within a namespace, named elements are uniquely identified by:

their signature

their visibility

their names

their internal number

8 / 14

In a Dependency the source elements are incomplete without the target elements.

True

False

9 / 14

Which of the following sentences about usage relationship is true?

In a usage relationship the dependency is limited to the implementation and it doesn't apply to the specification

In a usage relationship the dependency applies to both the specification and implementation

There can be no usage relationship between interfaces but there can be a dependency relationship

There can be a usage relationship between interfaces

There can be a dependency relationship between interfaces

10 / 14

In the following picture, what is "a"?

An InformationFlow

An InformationItem

The element that show the direction of the flow between two classifiers

The picture is wrong

11 / 14

Which of the following statements about dependency relationships are true?

A change in the supplier requires an update of the client

The client is incomplete without the supplier

The client sends data to the supplier

The supplier sends data to the client

The client requires the supplier for its specification or implementation

12 / 14

The marking of data types (e.g. «primitive») is a stereotype.

True

False

13 / 14

Which statement(s) about DataTypes is/are correct?

A DataType has no attributes

A DataType has no operations

Instances of a DataType are different even if their attribute values are equal

A DataType is a specialized class

An instance of a DataType has no identity

14 / 14

Which statement about usage relationships are true?

A change in the supplier requires an update of the client

The client is incomplete without the supplier

The client requires the supplier for its implementation

The supplier sends data to the client
