5. Function Point Computation is given by the formula
a) FP = [count total * 0.65] + 0.01 * sum(Fi)
b) FP = count total * [0.65 + 0.01 * sum(Fi)].
c) FP = count total * [0.65 + 0.01] * sum(Fi)
d) FP = [count total * 0.65 + 0.01] * sum(Fi)

6. Architectural Design Metrics are ___________ in nature.
a) Black Box
b) White Box
c) Gray Box
d) Green Box
Answer: a
Clarification: They are “black box” in that they do not require any knowledge of the inner workings of a particular software component.
7. Structural complexity of a module i is given as S(i) = f*f (i). What does f symbolizes here?
a) “fan check-out” of module i
b) “fan check-in” of module i
c) “fan in” of module i
d) “fan out” of module i
Answer: d
Clarification: Fan out is number of modules directly invoked by module i.
