1. A root cause analysis on escaped defects reveals 60% originated during requirements phase. Which action best addresses this finding? → Strengthen requirements review and static testing early in the lifecycle
2. A test conductor discovers that a colleague has been sharing test item content with examinees before the exam. What is the most appropriate immediate action? → Report the breach to the appropriate supervisor or ethics board
3. A test conductor's report shows 92% test pass rate, but post-release customer-reported defects are high. Which metric would have better predicted this outcome? → Defect detection percentage (DDP) benchmarked against post-release defects
4. A test article begins emitting an unidentified odor during operations. There are no instrument readings above red-line limits. The test conductor should: → Immediately initiate a shutdown and investigate the potential hazard
5. Which metric is MOST useful for a test conductor evaluating real-time data quality during execution? → Signal-to-noise ratio and data dropout rate across critical measurement channels
6. A test conductor must report test progress to both technical leads and executive sponsors. What is the best practice? → Create two reports: a detailed technical report and a high-level executive dashboard
7. The 'emergency shutdown sequence' for a propulsion test typically ends with which action? → Venting and safe-ing all propellant and pressurant systems
8. In exploratory testing, what is a 'test charter'? → A brief mission statement guiding exploration of a specific area
9. Which of the following is a key responsibility of the test conductor during the pre-test configuration verification? → Confirming that the test article and instrumentation match the approved test configuration
10. A HAZOP study uses guide words applied to process parameters to identify deviations. Which guide word indicates that a parameter is completely absent? → No / None
11. A CTC is reviewing a data acquisition system specification and sees a stated accuracy of ±0.5% FS. What does 'FS' mean? → Full Scale — the accuracy is ±0.5% of the maximum range of the instrument
12. A 'duplicate' anomaly disposition means: → The defect has already been reported under a different ticket number
13. What does 'measurement uncertainty' quantify in a test data context? → The range within which the true value of a measurement is expected to lie
14. When applying boundary value analysis to a field that accepts values 1–100, which set of values should be tested? → 0, 1, 2, 99, 100, 101
15. When designing tests for a system with 3 independent binary conditions, how many rules does a full decision table require? → 8
16. Which of the following is a primary, formal output of a well-conducted post-test debriefing session? → A list of documented action items with assigned owners and due dates.
17. After an emergency shutdown is executed, who is responsible for authorizing the resumption of test operations? → The designated test director or safety authority after a formal review
18. What information is typically included in a test range Communications Plan (COMPLAN)? → Assigned frequencies, call signs, net architecture, MECL, and contingency procedures
19. During a CTC test, a strain gauge reads a value outside its calibrated range. What is the correct immediate action? → Flag the data channel as suspect and notify the Test Director before proceeding
20. In a Hazard Analysis and Risk Assessment (HARA) for a test environment, the term 'severity' refers to: → The potential magnitude of harm if the hazardous event occurs
21. A Pareto analysis of defect categories shows that three categories account for 76% of all defects. How should a test conductor use this finding? → Prioritize test coverage and review efforts on those three categories first
22. Which of the following anomaly report fields ensures traceability back to the test plan? → Test case or test procedure identifier
23. In telemetry data validation, a 'gap' in the data record most commonly indicates: → A loss of RF link or recorder dropout during acquisition
24. What is the role of ethics in maintaining corporate governance? → To ensure transparency and fairness in decision-making.
25. Which onboard recorder characteristic is most critical for high-vibration flight test environments? → Solid-state memory with no moving parts
26. Which instrumentation specification defines the smallest detectable change in a measured value? → Resolution
27. During a test event, the word 'HOLD' is transmitted on the countdown net. What must all range stations do? → Cease all non-safety communications and await further instructions
28. During a test countdown, the test conductor initiates a 'GO/NO-GO' poll. What is the correct response from a station that is ready to proceed? → GO
29. What does the proword 'ROGER' confirm in test range radio communications? → The receiver has received and understood the last transmission
30. Which data normalization technique is used to compare defect counts fairly between a module with 500 lines of code and one with 50,000 lines? → Calculate defect density (defects per KLOC) for each module
