Q81.
How is the number of function points determined in the Early Design model?

a.

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

b.

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

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 inputs, outputs, inquiries, etc. Explanation:The Early Design model uses unadjusted function points (UFPs) as its basic size measure, which are counted in the same way as in FPA by counting the number of inputs, outputs, inquiries, etc.
Q82.
What is the main difference between the Application Composition model and the Early Design model in COCOMO 2?

a.

The Application Composition model counts Object Points while the Early Design model counts Function Points

b.

The Application Composition model is intended for prototyping efforts while the Early Design model is aimed at the architectural design stage

c.

The Application Composition model is based on counting system components of a large granularity, such as screens and reports, while the Early Design model is an FPA-like model

d.

The Application Composition model is based on counting Object Points while the Early Design model is based on counting Source Lines of Code

Discuss
Answer: (a).The Application Composition model counts Object Points while the Early Design model counts Function Points Explanation:The Application Composition model is based on counting the number of screens, reports, and 3GL components in the application while the Early Design model uses unadjusted function points as its basic size measure.
Q83.
What is the main advantage of using Object Points in the Application Composition model?

a.

Object Points are easier to determine than Function Points

b.

Object Points reflect the batch-oriented world of the 1970s

c.

Object Points are more accurate than Function Points

d.

Object Points are user-oriented measure of system function

Discuss
Answer: (a).Object Points are easier to determine than Function Points Explanation:The Application Composition model is based on counting Object Points which are considered to be easier to determine and at an earlier point in time than Function Points.
Q84.
How is the total effort in the Application Composition model estimated?

a.

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

b.

By determining the complexity level of each screen and report

c.

By using the numbers given in a classification table similar to those in FPA

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The total effort in the Application Composition model is estimated by counting the number of screens, reports and 3GL components in the application, determining the complexity level of each screen, report and 3GL component, using numbers from a classification table to determine relative effort, and summing the Object Points for the individual objects.
Q85.
How does the Post-Architecture model differ from the original COCOMO model?

a.

It uses a different set of cost drivers

b.

It uses a different base measure

c.

It has a different range of values for the exponent b

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The Post-Architecture model differs from the original COCOMO model in its set of cost drivers, the use of lines of code as its base measure, and the range of values of the exponent b.
Q86.
What are the differences between the COCOMO and COCOMO 2 set of cost drivers?

a.

Four new cost drivers have been introduced, two have been dropped, and the productivity influence of some cost drivers has been increased or decreased

b.

Two new cost drivers have been introduced, four have been dropped, and the productivity influence of some cost drivers has been increased or decreased

c.

Four new cost drivers have been introduced, four have been dropped, and the productivity influence of some cost drivers has been unchanged

d.

Two new cost drivers have been introduced, two have been dropped, and the productivity influence of some cost drivers has been unchanged

Discuss
Answer: (a).Four new cost drivers have been introduced, two have been dropped, and the productivity influence of some cost drivers has been increased or decreased Explanation:Four new cost drivers have been introduced, two have been dropped, and the productivity influence of some cost drivers has been increased or decreased in COCOMO 2.
Q87.
What is the formula used to determine the exponent b in the COCOMO 2 effort equation?

a.

b = 1.01 + 0.01 * ฮฃXi

b.

b = 1.01 + 0.01 * ฮฃWi

c.

b = 1.01 + 0.01 * ฮฃXi * ฮฃWi

d.

b = 1.01 + 0.01 * ฮฃYi

Discuss
Answer: (b).b = 1.01 + 0.01 * ฮฃWi Explanation:The exponent b for the effort equation in COCOMO 2 is determined by the formula: b = 1.01 + 0.01 * ฮฃWi where Wi are the five scale factors rated on a six-point scale from very low (5) to extra high (0).
Q88.
Can both KSLOC and UFP be used as a base measure in COCOMO 2?

a.

Yes

b.

No

c.

May be Yes or No

d.

Can't say

Discuss
Answer: (a).Yes Explanation:In COCOMO 2, the user may use both KSLOC and UFP as a base measure. It is also possible to use UFP for part of the system and then convert the counts to KSLOC counts before applying the effort equation.
Q89.
How is the effort estimated in the Application Composition model of COCOMO 2?

a.

by counting the number of screens, reports, and 3GL components in the application

b.

by determining the complexity level of each screen and report

c.

by using numbers given in a classification table similar to those in FPA

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:In the Application Composition model of COCOMO 2, the total effort is estimated by counting the number of screens, reports, and 3GL components in the application, determining the complexity level of each screen and report, using numbers given in a classification table similar to those in FPA, and summing the Object Points for the individual objects.
Q90.
How does COCOMO 2 handle reuse?

a.

By separately considering the fractions of the system that require redesign, recoding, and re-integration

b.

By accounting for the novelty of the project to the development organization

c.

By considering the percentage of significant risks that have been eliminated

d.

By reflecting the maturity of the project organization according to the Capability Maturity Model

Discuss
Answer: (a).By separately considering the fractions of the system that require redesign, recoding, and re-integration Explanation:In COCOMO 2, reuse is handled by separately considering the fractions of the system that require redesign, recoding, and re-integration, and using an adjustment factor (AAF) to lower the cost estimate if part of the system is reused.
