Q11.
What is encapsulation?

a.

The process of breaking down software into black boxes

b.

The process of making functionality available without exposing internal implementation details

c.

The process of developing reliable product components

d.

The process of interacting with component boxes

Discuss
Answer: (b).The process of making functionality available without exposing internal implementation details Explanation:Encapsulation is the process of making functionality available without exposing unnecessary internal implementation details.
Q12.
Can different groups develop component boxes?

a.

Yes

b.

No

c.

May be Yes or No

d.

Can't say

Discuss
Answer: (a).Yes Explanation:Component boxes can be developed by different groups or even different people.
Q13.
What do smaller component boxes usually provide?

a.

Specific functionality

b.

Low-level data management functions

c.

Generic functionality

d.

Unnecessary details

Discuss
Answer: (c).Generic functionality Explanation:Smaller component boxes usually provide generic functionality that can be used anywhere in the program where the specific functionality they provide is required.
Q14.
What is a module?

a.

A group of source-code files that are built together

b.

A binary file that contains isolated areas of a program’s executable

c.

An external, third-party library that adds certain functionality to a program

d.

A separate file that remains outside of the program even when shipped to the end user

Discuss
Answer: (b).A binary file that contains isolated areas of a program’s executable Explanation:A module is defined as a binary file that contains isolated areas of a program's executable.
Q15.
What are the two basic types of modules?

a.

Static libraries and dynamic libraries

b.

Static modules and dynamic modules

c.

Static components and dynamic components

d.

Static features and dynamic features

Discuss
Answer: (a).Static libraries and dynamic libraries Explanation:The two basic types of modules are static libraries and dynamic libraries.
Q16.
What is the difference between static libraries and dynamic libraries?

a.

Static libraries are embedded into the program, while dynamic libraries remain in a separate file.

b.

Static libraries allow for upgrading individual components in a program, while dynamic libraries are difficult to make out and isolate when looking at the program from a low-level perspective.

c.

Static libraries represent a feature or an area of functionality in the program, while dynamic libraries provide helpful hints regarding the program's architecture.

d.

Static libraries are difficult to detect while reversing, while dynamic libraries are very easy to detect while reversing and often simplify the reversing process.

Discuss
Answer: (a).Static libraries are embedded into the program, while dynamic libraries remain in a separate file. Explanation:Static libraries are embedded into the program, while dynamic libraries remain in a separate file.
Q17.
What is the purpose of dynamic libraries?

a.

To represent a certain component of a program

b.

To provide an external, third-party library that adds certain functionality to a program

c.

To upgrade individual components in a program without updating the entire program

d.

To make up a group of source-code files that are built together

Discuss
Answer: (c).To upgrade individual components in a program without updating the entire program Explanation:The purpose of dynamic libraries is to allow for upgrading individual components in a program without updating the entire program.
Q18.
Why are dynamic libraries easy to detect while reversing?

a.

Because they are embedded into the program

b.

Because they represent a certain feature or area of functionality in the program

c.

Because they remain in a separate file, even when the program is shipped to the end user

d.

Because their interfaces often provide helpful hints regarding the program's architecture

Discuss
Answer: (d).Because their interfaces often provide helpful hints regarding the program's architecture Explanation:Dynamic libraries are easy to detect while reversing because their interfaces often provide helpful hints regarding the program's architecture.
Q19.
What are the two basic code-level constructs that are considered the most fundamental building blocks for a program?

a.

Procedures and objects

b.

Libraries and modules

c.

Dynamic and static libraries

d.

Components and interfaces

Discuss
Answer: (a).Procedures and objects Explanation:The two basic code-level constructs that are considered the most fundamental building blocks for a program are procedures and objects.
Q20.
What is a procedure?

a.

A program component that has both data and code associated with it

b.

A piece of code with a well-defined purpose that can be invoked by other areas in the program

c.

A set of publicly accessible procedures that are associated with an object

d.

A program component that is not interested in any of its implementation details

Discuss
Answer: (b).A piece of code with a well-defined purpose that can be invoked by other areas in the program Explanation:A procedure is a piece of code, usually with a well-defined purpose, that can be invoked by other areas in the program.
