CompTIA A+ Core 2 (220-1002) — Question 285

Several users at an office have noticed their computers have been behaving erratically over the past hour. A technician suspects there may be a network worm or a hardware failure because all the affected computers were purchased together. Which of the following should the technician perform FIRST?

Answer options

• A. Download antivirus updates
• B. Update the device drivers
• C. Quarantine the affected systems
• D. Perform hardware diagnostics

Correct answer: C

Explanation

The correct first step is to quarantine the affected systems to prevent further spread of a potential network worm. Downloading antivirus updates or updating device drivers may not resolve the immediate issue, and performing hardware diagnostics should come after isolating the systems to avoid compromising network integrity.
