Q431.
What is the purpose of design methods in software design?

a.

To depict the design using a graphical notation

b.

To provide strategies and heuristics to guide the design process

c.

To focus on the essential issues and ignore irrelevant details

d.

To quantify design heuristics

Discuss
Answer: (b).To provide strategies and heuristics to guide the design process Explanation:Design methods in software design give strategies and guidelines to direct the design process, usually using a graphical notation to depict the design.
Q432.
What is the single most important principle of software design?

a.

Complexity

b.

System structure

c.

Information hiding

d.

Abstraction

Discuss
Answer: (c).Information hiding Explanation:The single most important principle of software design is information hiding. It concentrates on the essential issues and abstracts from the irrelevant details.
Q433.
What is the purpose of design documentation?

a.

To serve project managers, designers, testers, and programmers

b.

To give strategies and heuristics to guide the design process

c.

To assess a design with respect to quality issues

d.

To apply verification and validation techniques at the design stage

Discuss
Answer: (a).To serve project managers, designers, testers, and programmers Explanation:Design documentation serves various users such as project managers, designers, testers, and programmers. It provides useful guidelines for describing software designs and identifies the type of design documentation needed for each role.
Q434.
What is the purpose of design patterns?

a.

To provide a recurring solution to a standard problem

b.

To generate a lot of documentation

c.

To assess a design with respect to quality issues

d.

To apply verification and validation techniques at the design stage

Discuss
Answer: (a).To provide a recurring solution to a standard problem Explanation:Design patterns are collections of modules or classes that provide a useful abstraction and a recurring solution to a standard problem. They are often used in combination and the opposite of a pattern is an antipattern.
Q435.
What is a module in software design?

a.

A random piece of software

b.

An identifiable unit in the design that may consist of a single procedure, class or set of classes

c.

A unit in a programming language with respect to compilation

d.

A graphical representation of the design

Discuss
Answer: (b).An identifiable unit in the design that may consist of a single procedure, class or set of classes Explanation:A module in software design is defined as an identifiable unit in the design, which may consist of a single procedure, class, or set of classes, and has a clean interface to the outside world.
Q436.
What are the desirable features of a decomposition in software design?

a.

Complexity and system structure

b.

Abstraction, modularity, information hiding, complexity, and system structure

c.

Simplicity, clear separation of concepts, and restricted visibility of information

d.

Design methods and graphical notations

Discuss
Answer: (c).Simplicity, clear separation of concepts, and restricted visibility of information Explanation:The desirable features of a decomposition in software design are simplicity, clear separation of concepts into different modules, and restricted visibility (locality) of information.
Q437.
What is abstraction in software design?

a.

Focusing on the non-essential features and ignoring the details that are not relevant

b.

Concentrating on the essential features and ignoring the details that are not relevant

c.

Ignoring the essential features and focusing on the details that are not relevant

d.

Ignoring both the essential features and the details that are not relevant

Discuss
Answer: (b).Concentrating on the essential features and ignoring the details that are not relevant Explanation:Abstraction means focusing on the essential features and ignoring the details that are not relevant at the current level of work.
Q438.
What are the two types of abstraction in software design?

a.

Procedural Abstraction and Data Analysis

b.

Procedural Abstraction and Data Abstraction

c.

Data Abstraction and Data Analysis

d.

Data Abstraction and Procedural Analysis

Discuss
Answer: (b).Procedural Abstraction and Data Abstraction Explanation:The two types of abstraction in software design are Procedural Abstraction and Data Abstraction.
Q439.
What is the essence of the main-program-with-subroutines architectural style?

a.

Bottom-up decomposition

b.

Top-down decomposition

c.

Middle-up decomposition

d.

Side-down decomposition

Discuss
Answer: (b).Top-down decomposition Explanation:The essence of the main-program-with-subroutines architectural style is top-down decomposition, in which a problem is decomposed into subproblems and further decomposed into even simpler subproblems.
Q440.
What is the main idea behind procedural abstraction in software design?

a.

It focuses on the primitive language constructs.

b.

It is a process of decomposing a problem into subproblems.

c.

It focuses on details that are relevant.

d.

It is a process of concentrating on essential features.

Discuss
Answer: (b).It is a process of decomposing a problem into subproblems. Explanation:The main idea behind procedural abstraction in software design is to decompose a problem into subproblems, and each subproblem is handled in turn.
