Question $1$: Coupling between Objects $($CBO$)$ measures:

A$)$Class cohesion, because it indicates that some methods should be removed from the class.

B$)$Class coupling, because it measures to what extent the given class depends on other classes.

C$)$Class memory utilization, CBO estimates the memory needs of the class.

D$)$Response time, CBO is a performance metric.

Question $2$: A high value of Depth of Inheritance Tree $($DIT$)$ for a class indicates what?

A$)$The class is easy to test.

B$)$The class resuability is high.

C$)$The class is easy to maintain.

D$)$The class is easy to understand.

Question $3$: Modularity can be achieved by$...$

A$)$Dividing the class into fixed sized modules.

B$)$Increasing cohesion and lowering coupling.

C$)$Intensive use of inheritance.

D$)$Fixing the methods size to $30$ lines of code.

Question $4$: A high value of the Response for Class $($RFC$)$ metric indicates that....

A$)$The class testability and understandability are low.

B$)$The class is easy to understand $($high understandability$).$

C$)$The class is easy to test $($high testability$)$

D$)$The class modularity is high.

Question $5$: Functional independence is assessed using two qualitative criteria: $\_\_\_\_\_\_\_\_\_\_$ and $\_\_\_\_\_\_\_\_\_\_.$

A$)$Cohesion and coupling.

B$)$Coupling and consistency.

C$)$Consistency and connectivity.

D$)$Cohesion and consistency.

Question $6$: In the Goal$-$Question$-$Metric approach, the relation between a metric and a question is $1-$to$-1.$ That is$,$ the metric can be used to answer one question only.

A$)$True

B$)$False

Question $7$: Modularity can be increased if$....$

A$)$Use global variables.

B$)$Lower cohesion and increase coupling.

C$)$Lower coupling and increase cohesion.

D$)$Keep each method size less than $30$ lines of code.

Question $8$:A design concept called Blank $1$ suggests that any complex problem can be more easily handled if it is subdivided into pieces that can be solved independently.
