Test your understanding of verification and validation with 5 practice questions.

Practice Questions

Question 1

During reliability demonstration testing to show a failure rate below $2\times10^{-4}\,\mathrm{failures/h}$ at 90\% confidence with zero observed failures, approximately how many failure-free test hours $T$ are required?

Question 2

Which statistical test is most appropriate for comparing the means of two independent sample datasets at the 95\% confidence level in V&V data analysis?

Question 3

Which V&V review assesses whether system requirements accurately reflect stakeholder needs before design development?

Question 4

Which V&V environment uses a simulation of the system model without executing actual software or hardware, enabling early verification of control logic?

Question 5

Which failure analysis technique uses a top-down deductive approach to identify root causes by constructing a logic diagram of failure paths?
