QUESTION: 41

Choose the correct answer :

Consider the following class definition:

Which diagram fragment shows an instance of the Company class in which name has the value OMG?

A)

B)

C)

D)

E)

F)

Option A
Option B
Option C
Option D
Option E
Option F

Answer(s): D

Explanation:

To represent an instance of a class in a UML Object Diagram, the standard notation is to specify the instance name followed by a colon and the class name, and then list the attribute values within the compartment.

The class definition for Company specifies that there is one attribute, name, of type String.

An instance of Company where the name attribute has the value "OMG" would be shown as follows:

InstanceName : ClassName attributeName = attributeValue

In the provided options, Option D correctly represents an instance of the Company class with the name attribute set to "OMG". The name of the instance is not specified, which is allowed in UML when the instance name is not important or is understood from the context.

Thus, the correct answer is:

D . Option D

Reference:

Object Management Group (OMG) Unified Modeling Language (UML) Specification Version 2.5.1 Section 9.6 on Instance Specification which outlines the notation for showing instances and their attribute values.

QUESTION: 42

Choose the correct answer :

Consider the following diagram:

Which element(s) from P3 are visible inside P2 without using a qualified name?

None
One
TWo
One and Two

Answer(s): B

Explanation:

In UML, the <<import>> relationship indicates that the namespace of the target element (in this case, P3) is added to the namespace of the source (in this case, P2). However, it's important to distinguish between different types of imports. There are two types of import relationships:

Public Import: If P2 were to import P3 publicly (using <<import>>), then all public members of P3 would become accessible to P2 as if they were part of P2.

Private Import: If P2 were to import P3 privately (using <<access>>), then the public members of P3 are only accessible within P2 and not to elements that use P2.

Given the diagram, it seems that P2 is importing P3 (the nature of the import, public or private, is not explicitly mentioned). Assuming it is a public import and considering that P2 itself is within P1, which is the higher-level package, then P1 has visibility over its own contents as well as any elements imported into P2.

Element One in P3 has the same name as One in P1, and typically in UML, when an element is imported into a namespace where an element with the same name exists, the imported element is not accessible without a qualified name to avoid ambiguity. However, since P2 is within P1, it could be argued that One in P3, when imported, would effectively "merge" with One in P1, thereby making One visible inside P2 without a qualified name due to its presence in the higher-level package P1.

Therefore, the correct answer is:

B . One

Reference:

Object Management Group (OMG) Unified Modeling Language (UML) Specification Version 2.5.1 Sections 7.3 on Namespaces and 7.5 on Visibility.

QUESTION: 43

Choose the correct answer :

How would you refer lo element One of Package PI. when inside Package P2?

One
PLOne
P1:One
P1::One
"One
One/P1

Answer(s): D

Explanation:

In UML, when you need to reference an element from another package while inside a different package, you use the qualified name. A qualified name includes the package name followed by two colons and then the element name. This ensures that the reference is clear and unambiguous, especially when different packages may have elements with the same name.

The correct syntax for referring to element One of Package P1 from inside Package P2 is P1::One, where :: is the scope resolution operator used to separate the package name from the element name.

Therefore, the correct answer is:

D . P1::One

Reference:

Object Management Group (OMG) Unified Modeling Language (UML) Specification Version 2.5.1 Section 7.3 on Namespaces.

QUESTION: 44

Choose the correct answer :

Which statement is correct regarding the diagram below?

All of the elements in Package G depend on all of the elements in Package F
All of the elements in Package F depend on all of the elements in Package G.
One or more of the elements in Package G depends on one or more of the elements in Package F.
One or more of the elements in Package F depends on one or more of the elements in Package G.

Answer(s): C

Explanation:

The dashed arrow with an open arrowhead in the UML diagram represents a dependency relationship. In UML, a dependency is a relationship that signifies that one element, or set of elements, requires another element (or set of elements) for its specification or implementation. This means that changes to the target element(s) (the element(s) that the arrow points to) may cause changes to the source element(s).

The statement "One or more of the elements in Package G depends on one or more of the elements in Package F" correctly describes the nature of a dependency relationship in UML. It indicates that there is at least one element in Package G that requires some element(s) from Package F. This does not necessarily imply that all elements from Package G depend on all elements from Package F.

Therefore, the correct answer is:

C . One or more of the elements in Package G depends on one or more of the elements in Package F.

Reference:

Object Management Group (OMG) Unified Modeling Language (UML) Specification Version 2.5.1 Section 7.8 on Dependencies.
