Free CompTIA Linux+ XK0-005 Practice Question

Your server has a web application that should be accessible from the internet, but users report they are unable to connect. You have confirmed that the web server is running and that network connectivity is established. What should you check next to ensure that the firewall is not blocking the web application's traffic?

  • Use a network scanner to detect open ports on the server.

  • Verify that the firewall rules allow traffic on ports 80 (HTTP) and 443 (HTTPS).

  • Check the listening ports to ensure the server is listening on the correct interface.

  • Restart the web server service to ensure it is not a service issue.
