Q551.
What does the DIT(Depth of Inheritance Tree) value depend on?

a.

The size of the class

b.

The complexity of the method

c.

The relationships between modules

d.

The language being used

Discuss
Answer: (d).The language being used Explanation:The value of DIT (Depth of Inheritance Tree) is somewhat language-dependent. This means that the distance of a class to the root of its inheritance tree depends on the language being used.
Q552.
What does a high value of NOC suggest in Object-Oriented Metrics?

a.

Low complexity of the class.

b.

Proper abstraction of the parent class.

c.

High complexity of the class.

d.

Tight bindings with other components.

Discuss
Answer: (c).High complexity of the class. Explanation:A high value of NOC means a large number of descendants, which suggests that the class is complex and is to be used in a variety of settings.
Q553.
What does CBO measure in Object-Oriented Metrics?

a.

The size of a class.

b.

The number of other classes with which a class is coupled.

c.

The distance of a class to the root of its inheritance tree.

d.

The complexity of an individual method.

Discuss
Answer: (b).The number of other classes with which a class is coupled. Explanation:CBO is the main coupling metric for object-oriented systems and it counts the number of other classes with which a class is coupled.
Q554.
What is the objective of Demeter's Law in Object-Oriented Metrics?

a.

To count the number of methods in a class.

b.

To count the number of connections between bubbles.

c.

To reflect the empirical relations in the numerical relation system.

d.

To measure the quality of messages between classes.

Discuss
Answer: (d).To measure the quality of messages between classes. Explanation:Demeter's Law is used to measure the quality of messages between classes, and messages that conform to Demeter's Law are considered better than those that don't.
Q555.
What is used to calculate the complexity of a method in WMC(Weighted Methods per Class)?

a.

The number of methods in the class

b.

The length of the method

c.

The cyclomatic complexity of the method

d.

Any of the above options

Discuss
Answer: (d).Any of the above options Explanation:The complexity of a method in WMC(Weighted Methods per Class) can be assessed using metrics such as length, cyclomatic complexity, or any other relevant metric.
Q556.
What is the purpose of counting each entry in the class interface in WMC(Weighted Methods per Class) calculation?

a.

To determine the number of methods in the class

b.

To reflect the design effort required for each method

c.

To determine the complexity of the class

d.

To reflect the language-dependence of the class

Discuss
Answer: (b).To reflect the design effort required for each method Explanation:In WMC(Weighted Methods per Class), each entry in the class interface is counted as one method, as it represents an additional design effort that should be accounted for.
Q557.
What is the relationship between classes in an object-oriented design?

a.

A subtype-supertype hierarchy

b.

A collection of inheritance trees of medium height

c.

A tight binding with other components

d.

A coupling between bubbles

Discuss
Answer: (a).A subtype-supertype hierarchy Explanation:Classes in an object-oriented design are related through a subtype-supertype hierarchy, meaning that one class may inherit from another class.
Q558.
What is the purpose of DIT(Depth of Inheritance Tree) in object-oriented systems?

a.

To measure the complexity of a class

b.

To measure the distance of a class to the root of its inheritance tree

c.

To measure the tight binding with other components

d.

To measure the depth of the inheritance hierarchy

Discuss
Answer: (b).To measure the distance of a class to the root of its inheritance tree Explanation:DIT is the distance of a class to the root of its inheritance tree, which is used to reflect the amount of knowledge required to understand a class.
Q559.
What is NOC in the context of object-oriented systems?

a.

The number of immediate descendants of a class

b.

The distance of a class to the root of its inheritance tree

c.

The tight binding with other components

d.

The number of connections for each bubble

Discuss
Answer: (a).The number of immediate descendants of a class Explanation:NOC is a metric that counts the number of immediate descendants of a class, which may reflect the complexity of the class or the level of abstraction of the parent class.
Q560.
What is CBO in the context of object-oriented systems?

a.

The main coupling metric for object-oriented systems

b.

The distance of a class to the root of its inheritance tree

c.

The number of immediate descendants of a class

d.

The complexity of a method

Discuss
Answer: (a).The main coupling metric for object-oriented systems Explanation:CBO stands for "Coupling Between Objects". It is defined as the main coupling metric for object-oriented systems, and it counts the number of other classes with which a class is coupled. Two classes are considered coupled if a method of one class uses a method or state variable of the other class. A high value of CBO suggests tight bindings with other components, which is considered undesirable in object-oriented design.
