a.

Corrective maintenance

b.

Adaptive maintenance

c.

Perfective maintenance

d.

Preventive maintenance

Discuss
Answer: (d).Preventive maintenance Explanation:Preventive maintenance is concerned with increasing the system’s future maintainability. Updating documentation, adding comments, or improving the modular structure of a system are examples of preventive maintenance activities.
Q383.
Approximately what percentage of the total maintenance effort is spent on adapting software to environmental changes?

a.

25%

b.

50%

c.

75%

d.

100%

Discuss
Answer: (a).25% Explanation:Adaptive maintenance, adapting the software to changes in the environment, accounts for about 25% of the total maintenance effort.
Q384.
What is the primary cause of changes in user requirements?

a.

Evolution of reality

b.

Wear and tear of the system

c.

Hidden defects in the software

d.

Insufficient prior experience

Discuss
Answer: (a).Evolution of reality Explanation:Changes in user requirements are caused by the evolution of reality, the software models part of reality and the reality changes, thus the software has to change too.

What is the total percentage of maintenance cost spent on changes to accommodate changing user requirements?

a.

25%

b.

50%

c.

75%

d.

100%

Discuss
Answer: (b).50% Explanation:Half of the maintenance cost is spent on changes to accommodate changing user requirements, i.e. enhancements to the system.
Q386.
What is the software development process called when it becomes cyclic?

a.

Linear process

b.

Waterfall model

c.

Software life cycle

d.

Iterative process

Discuss
Answer: (c).Software life cycle Explanation:The software development process becomes cyclic, hence the phrase software life cycle, where backtracking to previous phases and iteration of earlier phases occur frequently.
Q387.
What should you do when you find errors in the software system you are testing and your manager suggests delivering it as is and replacing it later?

a.

Give in to your manager's suggestion

a.

Trust

b.

Power

c.

Knowledge

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The relationship between individuals in software development is often asymmetrical and involves trust, power, and knowledge. This relationship can create opportunities for unethical behavior, such as embezzlement.
Q389.

a.

A set of principles for professional behavior

b.

A set of clauses for specific professional behavior

c.

A set of aspirations for ethical judgment

d.

All of the above

Discuss
Answer: (a).A set of principles for professional behavior Explanation:IEEE and ACM have jointly developed a code of ethics for software engineers, which is a set of principles for professional behavior. These principles are further refined into clauses that express aspirations and obligations for professionals in software engineering.
Q390.
According to the software engineering code of ethics, what should a software engineer do when approving software?

a.

Approve the software without any concerns

b.

Approve the software only if it is safe, meets specifications, passes appropriate tests, and does not harm the environment

c.

Approve the software only if it is safe and meets specifications

d.

Approve the software only if it does not harm the environment

Discuss
Answer: (b).Approve the software only if it is safe, meets specifications, passes appropriate tests, and does not harm the environment Explanation:Clause 1.031 of the code of ethics states that a software engineer should approve software only if they have a well-founded belief that it is safe, meets specifications, passes appropriate tests, and does not diminish quality of life or privacy or harm the environment.
