   A developer added a new server block to NGINX to serve a second application on port 8080. After reloading NGINX, the new application is not reachable, and the error log shows 'bind() to 0.0.0.0:8080 failed (98: Address already in use)'. Which command should you run first to identify the process occupying the port?

   • Anginx -t
   • Bss -tlnp | grep :8080
   • Ciptables -L -n
   • Dsystemctl status nginx
