Q111.
According to McCall, what are the two levels of quality attributes?

a.

Higher-level and lower-level

b.

External and internal

c.

Subjective and objective

d.

Direct and indirect

Discuss
Answer: (b).External and internal Explanation:McCall's taxonomy of quality attributes distinguishes between higher-level quality attributes, known as quality factors, which are external attributes and can only be measured indirectly, and a second level of quality attributes, called quality criteria, which can be measured either subjectively or objectively.
Q112.
What is the definition of quality in the IEEE Glossary of Software Engineering Terminology?

a.

The degree to which a system, component, or process meets customer or user needs or expectations

b.

The number of defects encountered in a software system

c.

The reliability of a software system

d.

The maintainability of a software system

Discuss
Answer: (a).The degree to which a system, component, or process meets customer or user needs or expectations Explanation:According to the IEEE Glossary of Software Engineering Terminology, quality is defined as "the degree to which a system, component, or process meets customer or user needs or expectations."
Q113.
What are the two levels of quality attributes discussed in McCall's taxonomy?

a.

External and internal attributes

b.

Higher-level and lower-level attributes

c.

Subjective and objective attributes

d.

Direct and indirect attributes

Discuss
Answer: (b).Higher-level and lower-level attributes Explanation:McCall's taxonomy distinguishes between two levels of quality attributes: higher-level quality attributes, known as quality factors, and lower-level quality attributes, known as quality criteria.
Q114.
What are the examples of higher-level quality attributes in McCall's taxonomy?

a.

Correctness, reliability, usability

b.

Maintainability, testability, portability

c.

Number of defects encountered

d.

All of the above

Discuss
Answer: (b).Maintainability, testability, portability Explanation:According to McCall's taxonomy, higher-level quality attributes, known as quality factors, include maintainability, testability, portability, etc.
Q115.
Can external attributes be measured directly?

a.

Yes

b.

No

c.

May be Yes or No

d.

Can't say

Discuss
Answer: (b).No Explanation:According to McCall's taxonomy, higher-level quality attributes, known as quality factors, are external attributes and can be measured only indirectly.
Q116.
What is the relationship between the number of defects encountered and the reliability of a software system?

a.

Directly related

b.

Indirectly related

c.

Not related

d.

Can't be determined

Discuss
Answer: (b).Indirectly related Explanation:The relationship between the number of defects encountered and the reliability of a software system is less obvious, it is an indirect relationship that requires a theory to establish the relationship between them.
Q117.
What are the three classes of quality factors in McCall's taxonomy?

a.

Factors that pertain to the use of the software after it has become operational

b.

Factors that pertain to the maintainability of the system

c.

Factors that reflect the ease with which a transition to a new environment can be made

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The quality factors in McCall's taxonomy can be broadly categorized into three classes: those that pertain to the use of the software after it has become operational, those that pertain to the maintainability of the system, and those that reflect the ease with which a transition to a new environment can be made.
Q118.
What is the main difference between McCall's quality factors and the ISO standard 9126's quality characteristics?

a.

McCall's factors are heavily interrelated, whereas the ISO scheme is hierarchical

b.

McCall's factors only refer to process quality issues, whereas the ISO scheme only covers product quality

c.

McCall's factors include quality aspects that are visible to the user, whereas the ISO scheme does not

d.

McCall's factors include reusability, whereas the ISO scheme does not

Discuss
Answer: (a).McCall's factors are heavily interrelated, whereas the ISO scheme is hierarchical Explanation:The main difference between McCall's quality factors and the ISO standard 9126's quality characteristics is that McCall's factors are heavily interrelated, whereas the ISO scheme is hierarchical, with each sub-characteristic related to exactly one characteristic.
Q119.
What are the three classes of quality factors as defined by McCall?

a.

Use of software, maintainability, and ease of transition

b.

Correctness, reliability, and efficiency

c.

Integrity, usability, and testability

d.

Flexibility, portability, and reusability

Discuss
Answer: (a).Use of software, maintainability, and ease of transition Explanation:McCall categorizes quality factors into three classes: those factors that pertain to the use of the software after it has become operational, those factors that pertain to the maintainability of the system, and those factors that reflect the ease with which a transition to a new environment can be made.
Q120.
What does the ISO standard 9126 refers to?

a.

Software development process

b.

Software product

c.

Software maintenance

d.

Software security

Discuss
Answer: (b).Software product Explanation:The ISO standard 9126 is similar to McCall's taxonomy, but it focuses on defining a set of quality characteristics and sub-characteristics for software product, it does not cover process quality issues.
