Q71.
What is the basis of the Application Composition model in COCOMO 2?

a.

Counting Object Points

b.

Counting Function Points

c.

Counting Lines of Code

d.

Counting System Components

Discuss
Answer: (a).Counting Object Points Explanation:The Application Composition model in COCOMO 2 is based on counting Object Points. Object Points are used to measure the number of screens, reports, and 3GL modules in a software project. It is not related to objects as in object-oriented development.
Q72.
What is the main difference between Function Points used in FPA and Object Points used in the Application Composition model of COCOMO 2?

a.

Object Points are technology-dependent and reflect the batch-oriented world of the 1970s

b.

Function Points are user-oriented and measure system function

c.

Object Points are developer-oriented and measure system components of a large granularity

d.

Function Points are technology-independent and reflect the object-oriented development practices of the 1990s and 2000s

Discuss
Answer: (b).Function Points are user-oriented and measure system function Explanation:Function Points as used in FPA are intended to be a user-oriented measure of system function, and that the user functions measured are the inputs, outputs, inquiries, etc.
Q73.
What is the main advantage of Object Points over Function Points?

a.

They are easier to determine

b.

They reflect the batch-oriented world of the 1970s

c.

They are more accurate for administrative systems

d.

They are intended to be a user-oriented measure of system function

Discuss
Answer: (a).They are easier to determine Explanation:Object Points are easier to determine, and at an earlier point in time than Function Points.
Q74.
What is the main use of the Application Composition model in COCOMO 2?

a.

For the architectural design stage

b.

For the actual development stage of a software product

c.

For prototyping efforts, for instance to resolve user interface issues

d.

For counting system components of a large granularity

Discuss
Answer: (c).For prototyping efforts, for instance to resolve user interface issues Explanation:The Application Composition model is mainly intended for prototyping efforts, for instance to resolve user interface issues.
Q75.
How is the complexity level of each screen and report determined in the Application Composition model?

a.

By counting the number of views and tables it contains

b.

By counting the number of inputs, outputs, and inquiries

c.

By counting the number of sections and tables it contains

d.

By considering it always difficult

Discuss
Answer: (a).By counting the number of views and tables it contains Explanation:The complexity of a screen in the Application Composition model depends on the number of views and tables it contains.
Q76.
How is the total effort estimated in the Application Composition model?

a.

By determining the number of screens, reports, and 3GL components in the application

b.

By determining the number of inputs, outputs, and inquiries in the application

c.

By determining the number of sections and tables in the application

d.

By considering the application as always difficult

Discuss
Answer: (a).By determining the number of screens, reports, and 3GL components in the application Explanation:The first step in estimating total effort in the Application Composition model is estimating the number of screens, reports, and 3GL components in the application.
Q77.
How is the reuse percentage determined in the Application Composition model?

a.

By comparing Object Points with Function Points

b.

By estimating the number of screens, reports, and 3GL components in the application

c.

By determining the complexity level of each screen and report

d.

By dividing the number of Object Points by 100

Discuss
Answer: (d).By dividing the number of Object Points by 100 Explanation:The reuse percentage is determined by "dividing the number of Object Points by 100."
Q78.
What is the productivity rate used in the Application Composition model?

a.

The number of Object Points divided by the number of man-months

b.

The number of New Object Points divided by the number of man-months

c.

The number of man-months divided by the number of New Object Points

d.

The number of man-months divided by the number of Object Points

Discuss
Answer: (b).The number of New Object Points divided by the number of man-months Explanation:The productivity rate is "the number of New Object Points divided by the number of man-months" and that it "varies from 4 (very low) to 50 (very high)."
Q79.
What is the main purpose of the Application Composition model in COCOMO 2?

a.

To estimate the number of screens and reports in the application

b.

To determine the complexity level of each screen and report

c.

To estimate the total effort for the project

d.

To estimate the number of 3GL components in the application

Discuss
Answer: (c).To estimate the total effort for the project Explanation:The Application Composition model in COCOMO 2 is mainly intended for prototyping efforts, and it is used to estimate the total effort for the project by counting the number of screens, reports, and 3GL components in the application and determining their complexity levels.
Q80.
How are Object Points determined in the Application Composition model?

a.

By counting the number of inputs, outputs, inquiries, etc.

b.

By counting the number of screens, reports, and 3GL modules

c.

By counting the number of data elements and file types referenced

d.

By counting the number of menus or screens

Discuss
Answer: (b).By counting the number of screens, reports, and 3GL modules Explanation:In the Application Composition model, Object Points are determined by counting the number of screens, reports, and 3GL modules in the application, and determining their complexity levels.
