CompTIA A+ Core 2 (220-1102) — Question 89

A technician is troubleshooting a computer with a suspected short in the power supply. Which of the following is the FIRST step the technician should take?

Answer options

• A. Put on an ESD strap.
• B. Disconnect the power before servicing the PC.
• C. Place the PC on a grounded work bench.
• D. Place components on an ESD mat.

Correct answer: B

Explanation

The correct step is to disconnect the power before servicing the PC to ensure safety and prevent electric shock. While wearing an ESD strap, using a grounded workbench, and placing components on an ESD mat are all important for protecting components and the technician, they should be secondary actions taken after ensuring the device is powered down.
