B. 4, 3, 1, 2
C. 4, 1, 3, 2
D. 1, 3, 4, 2

4GL is an example of ________________ processing?

A. White Box
B. Black Box
C. Functional
D. Both Black Box & Functional

Explanation: Functional processing/testing is also referred to as black box testing in which contents of the black box are not known.Almost anything might be referred to as a black box:an algorithm or the human mind.Functionality of the black box is understood in terms of its inputs and outputs.

If you were a lead developer of a software company and you are asked to submit a project/product within a stipulated time-frame with no cost barriers, which model would you select ?

If you were a lead developer of a software company and you are asked to submit a project/product within a stipulated time-frame with no cost barriers, which model would you select ?

A. Waterfall
B. Spiral
C. RAD
D. Incremental

Explanation: RAD model is inapplicable to develop cheaper products/software/projects as the cost of modeling, hiring highly skilled developers/designers and automated code generation is very high.But here the cost is not an issue, so one can select this model as it reduces development time.

Which two of the following models will not be able to give the desired outcome if user’s participation is not involved?

by
Which two of the following models will not be able to give the desired outcome if user’s participation is not involved?

A. Waterfall & Spiral
B. RAD & Spiral
C. RAD & Waterfall
D. RAD & Prototyg

Explanation: Active Participation of user is involved in all the four phases of RAD model and in case of the Prototyg model we need user’s presence/involvement every time a new prototype is build or designed.

Which of the following life cycle model can be chosen if the development team has less experience on similar projects ?

by
Which of the following life cycle model can be chosen if the development team has less experience on similar projects ?

A. Spiral
B. Waterfall
C. RAD
D. Iterative Enhancement Model

Explanation: Relying on risk assessment/analysis provides more flexibility than required for many applications which overcomes the criteria of less experienced developers.
