Question 1: How do you identify a faulty transformer during troubleshooting?

Which action should you take?

Choose only one option

Test the transformer using a high-voltage probe

Measure the voltage on both primary and secondary sides

Measure the resistance of the windings

Inspect the transformer windings for physical damage

Question 2: What is the most likely cause of a voltage drop in a system under high load?

Which action should you take?

Choose only one option

Incorrectly configured software

Insufficient power supply capacity

Faulty ground connections

Overloaded components or circuits

Question 3: During a service visit, the client's operator asks repetitive questions showing uncertainty. How do you ensure they gain confidence without feeling patronized?

Which action should you take?

Choose only one option

Patiently re-explain key points with slight rewording each time, use visual aids, and offer a short recap at the end confirming their understanding

Dismiss their questions as obvious

Become impatient and technical

Tell them to read the manual

Question 4: You need to communicate complex firmware upgrade steps to a client's onsite technician who is time-constrained. How to ensure they can perform it correctly the first time?

Which action should you take?

Choose only one option

Give them the manual's entire firmware section

Send a lengthy text-only procedure

Create a concise step-by-step guide with clear bullet points, reference images, and highlight critical steps in bold, offer a brief video demo if possible

Rely on them to guess steps

Question 5: A high-voltage test station occasionally shows random undervoltage errors on the DUT. The internal power supply checks out. Before suspecting a load variation, which troubleshooting method identifies a hidden contact resistance in wiring?

Which action should you take?

Choose only one option

Use a four-wire measurement technique (Kelvin connections) on suspect cables and connectors to detect micro-ohm level contact resistance

Disable undervoltage alarms to see if it persists

Check event logs for undervoltage

Replace cables blindly

Question 6: Which is the best way to document recurring technical issues?

Which action should you take?

Choose only one option

Use a spreadsheet

Avoid documenting minor issues

Log issues in a centralized ticketing system

Use paper notes
