Question 1: In the context of test planning, what is the primary purpose of traceability matrices?

Which action should you take?

Choose only one option

To provide a roadmap for test execution

To ensure test cases cover all requirements

To monitor the progress of testing

To allocate testing resources effectively

Question 2: In terms of signal integrity, what is the impact of vias on high-speed signals?

Which action should you take?

Choose only one option

Vias improve the overall bandwidth of the signal path

Vias introduce additional inductance and capacitance, causing signal degradation

Vias have no impact on high-speed signal integrity

Vias help to reduce signal reflections by improving routing efficiency

Question 3: What could cause a voltage regulator to output an incorrect voltage?

Which action should you take?

Choose only one option

Power supply failure

Overload condition

Incorrect feedback loop

All of the above

Question 4: What is the primary cause of oscillations in a high-frequency circuit under test?

Which action should you take?

Choose only one option

Overdriven amplifier stages

Improper feedback loop design

Inadequate bypass capacitors

Grounding issues

Question 5: When diagnosing a fault in a low-power system, what is the most likely cause of malfunction?

Which action should you take?

Choose only one option

Power supply instability or insufficient current

Faulty signal routing

Incorrect software configuration

Component overheat

Question 6: What is the most effective way to manage the calibration of power supplies used in testing electrical systems?

Which action should you take?

Choose only one option

Recalibrate only after observing irregular output

Use a multimeter to manually adjust output settings

Use a known load to test the accuracy of the output voltage

Calibrate once every three months regardless of usage
