75 questions
120 min time limit
75% to pass
  1. When an IC chip becomes unusually hot during operation, the first diagnostic step should be: โ†’ Check for correct supply voltage and verify no output is shorted
  2. An inverting op-amp amplifier has a feedback resistor Rf = 10 kฮฉ and input resistor Rin = 2 kฮฉ. What is the closed-loop voltage gain? โ†’ -5
  3. An electronics technician finds a device in the shop with no visible FCC ID. What is the most likely compliance issue? โ†’ The device may have been sold without required FCC equipment authorization
  4. What does the slew rate of an op-amp specify? โ†’ The maximum rate of change of output voltage in V/ยตs
  5. In Reporting Requirements & Standards, what is the FIRST step a CET professional should take when encountering a new case or situation? โ†’ Conduct a comprehensive assessment and gather all relevant information
  6. In an electronics repair facility's registry, a 'nonconformance report' (NCR) is generated when: โ†’ A product or process fails to meet specified requirements
  7. A PNP transistor is suspected faulty. Using a DMM in diode-check mode, the base-emitter junction should read approximately: โ†’ 0.6โ€“0.7V with positive lead on emitter, near OL reversed
  8. What does a Ground Fault Circuit Interrupter (GFCI) outlet protect against? โ†’ Electric shock from current leaking to ground through a person
  9. What is the primary purpose of a 'nonconformance report' (NCR) in electronics production? โ†’ To document products or processes that do not meet specified requirements
  10. What is the purpose of thermal imaging in electronics troubleshooting? โ†’ To detect hot spots in circuits and identify faulty components.
  11. A technician discovers a hard drive containing customer records while repairing a computer. The best course of action is to: โ†’ Avoid accessing personal data and inform the customer
  12. Which ISO standard provides the framework for quality management systems most often referenced in electronics manufacturing compliance reports? โ†’ ISO 9001
  13. In a preventive maintenance registry, 'MTBF' is used to schedule service intervals. What does MTBF stand for? โ†’ Mean Time Between Failures
  14. In a multistage amplifier, the overall bandwidth compared to a single stage is: โ†’ Narrower
  15. What is the PRIMARY purpose of continuing education requirements in Cancer Registry Data Collection for CET professionals? โ†’ Maintaining current knowledge and competency as the field evolves
  16. In preventive maintenance registry systems, the term 'condition-based maintenance' (CBM) differs from time-based maintenance in that CBM: โ†’ Is triggered by actual equipment condition data rather than fixed time intervals
  17. In asset registry management, 'depreciation schedule' information is relevant because it: โ†’ Supports financial reporting and replacement planning
  18. In TNM staging, what does 'N0' indicate? โ†’ No regional lymph node involvement
  19. Which of the following scenarios requires a Corrective Action Report (CAR)? โ†’ A recurring solder defect is identified across multiple production batches
  20. Which FCC regulation part primarily governs unintentional radiators such as digital devices and computers? โ†’ FCC Part 15
  21. What tool is commonly used for measuring the voltage in a circuit? โ†’ Multimeter
  22. Which standard of practice is MOST important for ensuring quality in Cancer Registry Data Collection? โ†’ Following evidence-based protocols while adapting to specific circumstances
  23. What is the function of a buffer stage inserted between two amplifier stages? โ†’ Provide high input impedance and low output impedance to prevent loading
  24. In decibel notation, a two-stage amplifier with each stage providing 20 dB gain has a total gain of: โ†’ 40 dB
  25. What constitutes 'first course of treatment' in cancer registry documentation? โ†’ All planned treatment given before disease progression or recurrence
  26. How is the 'date of diagnosis' defined in cancer registry abstraction? โ†’ Date of the first positive histologic or cytologic confirmation of malignancy
  27. What is the primary advantage of a switching power supply over a linear regulator for the same output power? โ†’ Much higher efficiency (often 80โ€“95%) because the switching transistor is either on or off
  28. A technician tests a power supply and finds output voltage is within tolerance. How should this result be recorded? โ†’ Measured value, specification limits, pass/fail result, and date/technician signature
  29. When using an oscilloscope to troubleshoot, a waveform appears 'clipped' at the top. This most likely indicates: โ†’ Amplifier saturation or clipping
  30. A technician is asked to repair a device that may contain evidence in a criminal investigation. The technician should FIRST: โ†’ Consult with law enforcement or legal counsel before proceeding

What Practice Test Geeks adds beyond an AI chat for CET

An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:

  • A timed, full-length CET mock exam โ€” 75 questions in 120 minutes with a 75% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
  • A fixed CET question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
  • Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
  • CET flashcards built from the same question bank.
  • Free CET practice tests with the correct answer shown after each question.
