53. How many feasibility studies is conducted in Requirement Analysis ?

by
A. Two
B. Three
C. Four
D. None of the mentioned
✅ The correct answer is option B.
Explanation: Economic feasibility (cost/benefit analysis), Technical feasibility (hardware/software/people, etc.) and Legal feasibility studies are done in Requirement Analysis.

54. Why is Requirements Elicitation a difficult task ?

by
A. Problem of scope
B. Problem of understanding
C. Problem of volatility
D. All of the mentioned
✅ The correct answer is option D.
Explanation: Users specify unnecessary technical detail that may confuse, rather than clarify overall system objectives.Also, the customers/users are not completely sure of what is needed, have a poor understanding of the capabilities and limitations of their computing environment and they do not understand that the requirements change over time

55. Consider the following Statement: “The output of a program shall be given within 10 secs of event X 10% of the time.”What characteristic of SRS is being depicted here ?

by
A. Consistent
