Explanation: Build & Fix Model is suitable for 100-200 LOC
7. RAD Model has
a) 2 phases
b) 3 phase
c) 5 phases
d) 6 phases

Answer:c
Explanation: RAD Model consists of five phases namely:Business modeling,Data modeling,Process modeling,Application generation and Testing & Turnover.
8. What is the major drawback of using RAD Model?
a) Highly specialized & skilled developers/designers are required.
b) Increases re-usability of components.
c) Encourages customer/client feedback.
d) Both a & c.

Answer:d
Explanation: The client may create an unrealistic product vision leading a team to over or under-develop functionality.Also, the specialized & skilled developers are not easily available.
