Question 1

What does a simple name in UML Class and objects consists of ?
A)letters
B)digits
C)punctuation characters
D)all of the mentioned

Accepted Answer

Simple names in UML (Unified Modeling Language) can consist of letters, digits, and punctuation characters, allowing for a wide range of naming conventions.

Question 2

What Does a Composite name consists of in a UML Class and object diagram ?
A)delimiter
B)simple names
C)digits
D)all of the mentioned

Accepted Answer

In UML Class and object diagrams, a composite name can consist of delimiters, simple names, and digits, essentially all of the mentioned components. This allows for the representation of complex naming conventions and hierarchies within the diagram.

Question 3

A class is divided into which of these compartments ?
A)name compartment
B)attribute compartment
C)operation compartment
D)all of the mentioned

Accepted Answer

In the context of UML (Unified Modeling Language) class diagrams, a class is divided into compartments that typically include the name compartment, attribute compartment, and operation compartment. These compartments help in organizing the properties and behaviors of the class, making the diagram easier to understand.

Question 4

An attribute is a data item held by which of the following ?
A)class
B)object
C)all of the mentioned
D)none of the mentioned

Accepted Answer

Attributes are data items held by both classes and objects. In object-oriented programming, classes define the structure of objects, including their attributes, while objects are instances of classes that hold actual data values for these attributes.

Question 5

What should be mentioned as attributes for conceptual modelling ?
A)initial values
B)names
C)all of the mentioned
D)none of the mentioned

Accepted Answer

Conceptual modeling focuses on capturing the high-level design of a system, including the key concepts and their relationships. Attributes such as names are essential for identifying and describing these concepts. While initial values might not always be specified at the conceptual level, they can be included to provide a more complete understanding of the system's behavior from the outset. Therefore, "all of the mentioned" is the correct choice, as both names and initial values can be relevant attributes in conceptual modeling.

Question 6

Which of these are part of class operation specification format ?
A)name
B)parameter list
C)return-type list
D)all of the mentioned

Accepted Answer

The class operation specification format includes the name of the operation, the parameter list (inputs), and the return-type list (outputs), making all of the mentioned options correct.

Question 7

Which among the following are not the valid notations for package and component diagram?
A)notes
B)box
C)extension mechanisms
D)packages

Accepted Answer

The answer of Which among the following are not the...

Question 8

Which of the following is false?
A)a note is a dog-eared box connected to any model element by a dashed line
B)the main way to extend uml is by constraints, properties, etc
C)a dependency relation holds between two entities d and i where change in i does not affect d
D)all of the mentioned

Accepted Answer

A dependency relation in UML actually implies that a change in the independent entity (i) could affect the dependent entity (d), not the other way around as stated in option C.

Question 9

Which of these depicts the true definition for the UML extensions?
A)a constraint is the statement that must be true of the entities designated by one or more model elements
B)a property is a characteristic of the entity designated by a model element
C)a stereotype is a uml model element given more specific meaning
D)all of the mentioned

Accepted Answer

All options correctly describe aspects of UML extensions: constraints define conditions that must hold true for model elements, properties characterize entities within the model, and stereotypes extend model elements with additional meanings.

Question 10

Which of the following in incorrect in reference to dependency?
A)module d uses module i when a correct version of i must be present for d to work correctly
B)module d depends for compilation on module i
C)class i imports elements from package d
D)none of the mentioned

Accepted Answer

Class i importing elements from package d indicates a dependency of class i on package d, not the other way around.

Question 11

What is collection of model elements called?
A)box
B)dependency
C)uml packages
D)package members

Accepted Answer

The answer of What is collection of model elements called?
A)box
B)dependency
C)uml...

Question 12

What types of units does Component follow?
A)modular unit
B)replaceable unit
C)unit with well defined interface
D)all of the mentioned

Accepted Answer

Components follow all the mentioned types: they are modular, replaceable, and have well-defined interfaces, making them integral to software design and architecture.

Question 13

Which of these is true with respect to interfaces?
A)interfaces in component diagram defines relationship between components and environment
B)interfaces realized by a class or a component are required interfaces
C)interface on which a class or component depends are called provided interfaces
D)all of the mentioned

Accepted Answer

Interfaces in a component diagram indeed define the relationship between components and their environment, specifying how they interact with other components or systems.

Question 14

What is delegation connector?
A)a delegation connector ties a component interface to one or more internal classes or components
B)delegation connectors are solid arrows stereotyped <>
C)a delegation connector may also extend from an internal class to an external interface
D)all of the mentioned

Accepted Answer

A delegation connector ties a component interface to one or more internal classes or components, and a delegation connector may also extend from an internal class to an external interface.

Question 15

Which of these are diagrammatic heuristics?
A)use notes, constraints, properties and stereotypes to add information to uml models
B)use stereotypes to name dependencies
C)use packages to group elements in static models
D)all of the mentioned

Accepted Answer

Diagrammatic heuristics involve strategies to enhance the clarity and effectiveness of diagrams. This includes using notes, constraints, properties, and stereotypes to add information to UML models, using stereotypes to name dependencies, and using packages to group elements in static models. All these practices help in making the diagrams more informative and easier to understand.

Question 16

Which of the following is true ?
A)a logical architecture is the realization of product as code and data files residing and executing on computational resource
B)a physical architecture is the configuration of product's major constituents
C)all of the mentioned
D)none of the mentioned

Accepted Answer

The answer of Which of the following is true ?
A)a...

Question 17

Which among these are the common notations for deployment diagrams?
A)artifacts and nodes
B)stereotypes
C)components
D)all of the mentioned

Accepted Answer

The answer of Which among these are the common notations...

Question 18

Which of the following is true?
A)a uml artifact is any physical representation of data used or produced during software development or software product operation
B)a node is a computational resource
C)all of the mentioned
D)none of the mentioned

Accepted Answer

All of the mentioned statements are true. A UML artifact indeed represents any physical piece of information used or produced in the software development process, and a node represents a computational resource in UML diagrams.

Question 19

Which are the ways to represent nodes in a deployment diagram?
A)nodes instances are underlined identifiers of the form name:type
B)the name may be left off,indicating an unnamed instance of the type
C)the type may be left off, indicating a named instance with an unspecified type
D)all of the mentioned

Accepted Answer

In a deployment diagram, all the mentioned ways (A, B, C) are valid for representing nodes. This includes using underlined identifiers with a name and type, allowing for unnamed instances with a specified type, and permitting named instances with an unspecified type.

Question 20

What does a deployment diagram consists of?
A)computational resource
B)communication path between resource
C)artifacts that execute resource
D)all of the mentioned

Accepted Answer

Deployment diagrams in UML include computational resources, communication paths between resources, and artifacts that execute on these resources, thus encompassing all the mentioned elements.
