CompTIA A+ Core 2 (220-1002) — Question 356

A technician is investigating the cause of a Windows 7 PC running very slow. While reviewing Task Manager, the technician finds one process is using more than
90% of the CPU. Outbound network traffic on port 25 is very high, while inbound network traffic is low. Which of the following tasks should be done FIRST?

Answer options

• A. Disconnect the network cable.
• B. Update the antivirus software.
• C. Run an antivirus scan.
• D. Shut down the PC.

Correct answer: A

Explanation

The correct action is to disconnect the network cable to prevent further data transmission, which likely indicates a compromise or malware affecting the system. Updating antivirus software and running a scan are important but should be done after immediate threats are contained. Shutting down the PC is not a proactive measure to address the ongoing issue.
