✍️ Sample CET Questions & Answers

1. A technician is asked to repair a device that may contain evidence in a criminal investigation. The technician should FIRST:

✓ Consult with law enforcement or legal counsel before proceeding

Devices involved in legal investigations must be handled according to legal protocols; proceeding without guidance could compromise evidence or expose the technician to liability.

2. What is the primary purpose of a 'nonconformance report' (NCR) in electronics production?

✓ To document products or processes that do not meet specified requirements

An NCR formally identifies and documents any product, component, or process that fails to meet defined specifications or standards.

3. A PNP transistor is suspected faulty. Using a DMM in diode-check mode, the base-emitter junction should read approximately:

✓ 0.6–0.7V with positive lead on emitter, near OL reversed

For a PNP transistor, the base-emitter junction forward biases with the positive lead on the emitter (P-type).

4. What is 'data at rest' in the context of electronics security?

✓ Data stored on a device or media not currently being transferred

Data at rest refers to inactive data stored physically on drives, SSDs, USB sticks, or other media, as opposed to data in transit or in use.

5. Which standard of practice is MOST important for ensuring quality in Follow-Up & Survival Analysis?

✓ Following evidence-based protocols while adapting to specific circumstances

Evidence-based protocols provide a foundation of proven practices, but effective Certified Electronics Technician professionals must also adapt their approach based on specific circumstances and individual case needs within Follow-Up & Survival Analysis.

6. An inverting op-amp amplifier has a feedback resistor Rf = 10 kΩ and input resistor Rin = 2 kΩ. What is the closed-loop voltage gain?

✓ -5

Inverting amplifier gain = -Rf/Rin = -10k/2k = -5.

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 — 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.
A printable CET cheat sheet you can print or save as a PDF.
CET flashcards built from the same question bank.
Free CET practice tests with the correct answer shown after each question.
