42. The major shortcoming of waterfall model is

  • Option : A
  • Explanation :
    The major shortcoming of waterfall model is the difficulty in accommodating changes after requirement analysis. System testing, maintenance of system and accommodating changes after feasibility analysisare minor shortcoming. For more information on waterfall model Refer:Software Engineering | Classical Waterfall Model. Option (A) is correct.

43. The quick design of a software that is visible to end users leads to _____.

  • Option : B
  • Explanation :
  • The quick design of a software that is visible to end users leads to prototype model.
  • The iterative waterfall model provides feedback paths from every phase to its preceding phases.
  • Spiral model is one of the most important Software Development Life Cycle models, which provides support for Risk Handling.
  • Classical waterfall model is the basic software development life cycle model. It is very simple but idealistic.
  • So, option (B) is correct.

44. For a program of k variables, boundary value analysis yields ______ test cases.

  • Option : C
  • Explanation :
    For a program of k variables boundary value analysis yields 4 * k + 1 test Robustness testing yields 6 * k + 1 worst case testing yields 5 * k. So, option (C) is correct.

  • Option : C
  • Explanation :
  • The extent to which a software performs its intended functions without failures, is termed as reliability.
  • Robustness: The ability to withstand or overcome adverse conditions or rigorous testing.
  • Correctness: the quality or state of being free from error; accuracy.
  • Accuracy: the degree to which the result of a measurement, calculation, or specification conforms to the correct value or a standard.
  • So, option (C) is correct.
