CompTIA A+ Core 2 (220-1202) — Question 121

After clicking on an advertisement, a user reports that their browser is slow. A technician looks at the network connections for the machine and notices a large number of outbound connections. Which of the following actions should the technician take next?

Answer options

• A. Enable the firewall.
• B. Run antivirus scans.
• C. Reboot the computer.
• D. Quarantine the system.

Correct answer: D

Explanation

Quarantining the system is the most appropriate response as it prevents further network activity that could compromise security. Enabling the firewall may provide some protection but does not address the immediate issue. Running antivirus scans is important but should come after isolating the system to prevent further damage. Rebooting the computer does not solve the underlying problem.
