CompTIA A+ Core 2 (220-1002) — Question 233

A technician is working on a desktop computer that is not performing as expected. Program windows sometimes open and close without user intervention.
Windows cannot check for OS updates, and some websites are not accessible. Which of the following tasks should the technician perform FIRST?

Answer options

• A. Roll back recent driver updates.
• B. Replace the defective keyboard.
• C. Reset all the settings in the Internet Options.
• D. Unplug the Ethernet cable.

Correct answer: D

Explanation

The correct first step is to unplug the Ethernet cable, as this will immediately stop any external interference or remote access that might be causing the erratic behavior. The other options, such as rolling back drivers or replacing hardware, may be relevant later but do not address the potential immediate cause of the problem.
