Q61.
What is the starting point for transformations in reverse engineering?

a.

Program code

b.

Existing design

c.

Requirements specification

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Each of the transformations starts from a given description of the system to be transformed. In most cases, this will be the program code, but it is also possible to restructure an existing design or reconstruct a requirements specification for a given design.
Q62.
What is the modern name for restructuring in software development?

a.

Refactoring

b.

Migration

c.

Reengineering

d.

Reusable building blocks

Discuss
Answer: (a).Refactoring Explanation:The modern name for restructuring in software development is refactoring.
Q63.
In what phase of software development is refactoring a viable option?

a.

Evolution stage

b.

Servicing stage

c.

Design stage

d.

Maintenance stage

Discuss
Answer: (a).Evolution stage Explanation:Refactoring is a viable option during the evolution stage of software development when knowledge about the system is still around.
Q64.
What is the purpose of refactoring in software development?

a.

To keep the software maintainable

b.

To introduce more problems than it solves

c.

To add a wrapper

d.

To increase software complexity

Discuss
Answer: (a).To keep the software maintainable Explanation:Refactoring is applied in software development to keep the software maintainable as the second law of software evolution states that software becomes increasingly complex over time.
Q65.
What are bad smells in software development according to Fowler (1999)?

a.

Occurrences of substandard code quality

b.

Wrapper techniques

c.

Code improvements

d.

Reusable building blocks

Discuss
Answer: (a).Occurrences of substandard code quality Explanation:Fowler (1999) used the term bad smells to indicate occurrences of substandard code quality in software development.
Q66.
What is refactoring considered as in XP and other agile methods?

a.

An explicit method step

b.

A somewhat unnoticed activity

c.

A hidden technique

d.

A secret practice

Discuss
Answer: (a).An explicit method step Explanation:In XP and other agile methods, refactoring is considered as an explicit method step.
Q67.
What does the second law of software evolution tell us?

a.

To never refactor software

b.

To refactor software only when it's broken

c.

To refactor software as it becomes more complex over time

d.

To never touch the software after the evolution stage

Discuss
Answer: (c).To refactor software as it becomes more complex over time Explanation:The second law of software evolution states that software becomes increasingly complex over time, so we are forced to apply refactoring to keep the software maintainable.
Q68.
When is refactoring not a viable option?

a.

During the evolution stage

b.

During the servicing stage

c.

During the development stage

d.

During the testing stage

Discuss
Answer: (b).During the servicing stage Explanation:During the servicing stage, knowledge will have vaporized to some extent, and refactoring then may well introduce more problems than it solves.
Q69.
What are the "Bad Smells" in software development?

a.

Good coding practices

b.

Efficient algorithms

c.

Common mistakes and design issues

d.

Advanced coding techniques

Discuss
Answer: (c).Common mistakes and design issues Explanation:"Bad Smells" in software development refers to common mistakes and design issues in the code, which hinder the performance and efficiency of the software.
Q70.
What is the categorization of "Bad Smells" in software development according to Mantyla et al. (2003)?

a.

Five categories

b.

Six categories

c.

Seven categories

d.

Nine categories

Discuss
Answer: (c).Seven categories Explanation:Mantyla et al. (2003) categorizes "Bad Smells" in software development into seven broad categories. These categories provide handles to identify the type of situation that needs refactoring.
