What is the role of a tool for design recovery in a dialog with the human user?

a.

Search for patterns

b.

Transform a flawed design into a good one

c.

Highlight components that have been changed frequently

d.

Show the execution flow of a program

Discuss
Answer: (a).Search for patterns Explanation:Such a tool may, in a dialog with the human user, search for patterns, make suggestions, indicate relations between components, etc.
Q102.
What is the effect of eliminating gotos and redundancy on maintenance performance according to a study by Gibson and Senn (1989)?

a.

Increases the time required to perform maintenance

b.

Increases the frequency of ripple effects

c.

Decreases the time required to perform maintenance and the frequency of ripple effects

d.

Has no effect on maintenance performance

Discuss
Answer: (c).Decreases the time required to perform maintenance and the frequency of ripple effects Explanation:It was found that eliminating gotos and redundancy appears to decrease both the time required to perform maintenance and the frequency of ripple effects.
Q103.
What is the merit of restructuring tools limited to?

a.

Transforming a flawed design into a good one

b.

Structuring the control flow of Cobol programs

c.

Easily reading and understanding a well-structured program

d.

Improving maintenance performance

Discuss
Answer: (a).Transforming a flawed design into a good one Explanation:The merit of restructuring tools is limited. They will not transform a flawed design into a good one.
Q104.
What is the purpose of Lehman and Belady's study on software evolution?

a.

To predict the future evolution of a specific system

b.

To study the differences between successive versions of a system

c.

To understand the regularity in the evolution of software

d.

To reengineer components based on past information

Discuss
Answer: (c).To understand the regularity in the evolution of software Explanation:Lehman and Belady studied the evolution of software systems and formulated their well-known laws of software evolution to understand the regularity in the evolution of software.
Q105.
What is the basis of decision making in software evolution?

a.

Components that have changed the least in the past

b.

Components that have changed the most in the near future

c.

Components that have changed a lot in the recent past

d.

Components that have changed a lot over time

Discuss
Answer: (c).Components that have changed a lot in the recent past Explanation:The assumption is that components that changed a lot in the recent past are likely to change in the near future too. So, the decision on which components to reengineer is based on the components that have changed a lot in the recent past.
Q106.
What is the term used by Gırba et al. (2004) to characterize the idea of predicting future evolution of a software system?

a.

Yesterday's weather

b.

Today's weather

c.

Tomorrow's weather

d.

Past's weather

Discuss
Answer: (a).Yesterday's weather Explanation:Gırba et al. (2004) used the term "yesterday's weather" to characterize the idea of predicting the future evolution of a software system based on the actual evolution till now.
Q107.
What are the two types of analysis of evolutionary data distinguished by Gırba and Ducasse (2006)?

a.

Yesterday's weather analysis and today's weather analysis

b.

Version-centered analysis and history-centered analysis

c.

Past analysis and future analysis

d.

Regularity analysis and irregularity analysis

Discuss
Answer: (b).Version-centered analysis and history-centered analysis Explanation:Gırba and Ducasse (2006) distinguish two types of analysis of evolutionary data: version-centered analysis and history-centered analysis.
