Q21.
What is the result of some organizations not following the IEEE definition of software maintenance?

a.

A clearer picture of maintenance effort

b.

A more accurate picture of maintenance effort

c.

A blurrier picture of maintenance effort

d.

No effect on the picture of maintenance effort

Discuss
Answer: (c).A blurrier picture of maintenance effort Explanation:In many organizations, the definition of software maintenance does not follow the IEEE definition. This can lead to a blurring of the picture of maintenance effort.
Q22.
What is the first stage of the maintenance life cycle?

a.

Evolution stage

b.

Servicing stage

c.

Introductory stage

d.

Decline stage

Discuss
Answer: (c).Introductory stage Explanation:During the introductory stage of a new system, most of the effort is spent on user support.
Q23.
During which stage of the maintenance life cycle is emphasis placed on correcting faults?

a.

Evolution stage

b.

Servicing stage

c.

Introductory stage

d.

Growth stage

Discuss
Answer: (d).Growth stage Explanation:During the growth stage, emphasis is on correcting faults.
Q24.
What type of maintenance tasks are common during the decline stage?

a.

User support

b.

Correction of faults

c.

Enhancement of the system

d.

Technology replacement

Discuss
Answer: (d).Technology replacement Explanation:During the decline stage, technology replacement such as another platform or user interface kit constitutes a major category of maintenance tasks.
Q25.
What is necessary for successful maintenance?

a.

Knowledge of the application

b.

Patches and wrappers

c.

Scant knowledge

d.

Tactical changes

Discuss
Answer: (a).Knowledge of the application Explanation:Successful maintenance requires knowledge of the application.
Q26.
When does the knowledge of the application usually become scant?

a.

During the evolution stage

b.

During the servicing stage

c.

During the introductory stage

d.

During the decline stage

Discuss
Answer: (d).During the decline stage Explanation:Over time, the knowledge of the application vaporizes and at some point in time, it has become scant, which coincides with the transition from the mature stage to the declining stage.
Q27.
What is the main activity of code-related tasks in maintenance?

a.

Isolation

b.

Modification

c.

Testing

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:For the code-related tasks, the main activities are Isolation, Modification, and Testing.
Q28.
How much effort does isolation take in a single maintenance task?

a.

40%

b.

30%

c.

50%

d.

20%

Discuss
Answer: (a).40% Explanation:As a rule of thumb, isolation takes about 40% of effort in a single maintenance task.
Q29.
Which type of maintenance task takes the most effort in isolation?

a.

Corrective maintenance

b.

Adaptive maintenance

c.

Both take the same amount of effort

d.

None of the above

Discuss
Answer: (a).Corrective maintenance Explanation:During corrective maintenance, the fault that caused the failure has to be found, and this may take a lot of effort. So, isolation takes an even larger share in corrective maintenance.
Q30.
Which type of maintenance task takes the most effort in modification?

a.

Corrective maintenance

b.

Adaptive maintenance

c.

Both take the same amount of effort

d.

None of the above

Discuss
Answer: (b).Adaptive maintenance Explanation:For adaptive maintenance tasks, the actual modification takes longer. The reverse holds for adaptive maintenance tasks.
