   A company runs a legacy TCP-based inventory service on port 9000 at 10.0.0.10. They want NGINX to accept client connections on port 9000 and forward them to the backend. The NGINX server has one network interface with IP 192.168.1.10. Which configuration block correctly implements this socket proxy?

   • Astream { server { listen 192.168.1.10:9000; proxy_pass 10.0.0.10:9000; } }
   • Bstream { server { listen 9000; proxy_pass http://10.0.0.10:9000; } }
   • Cevents { server { listen 192.168.1.10:9000; proxy_pass 10.0.0.10:9000; } }
   • Dhttp { server { listen 192.168.1.10:9000; proxy_pass 10.0.0.10:9000; } }

   A team runs a TCP service on three backends. They want NGINX to send new connections to the backend with the fewest active connections. Which upstream configuration achieves this?

   • Astream { upstream backends { server 10.0.0.81:9000; server 10.0.0.82:9000; server 10.0.0.83:9000; least_conn; } server { listen 9000; proxy_pass backends; } }
   • Bstream { upstream backends { least_conn; server 10.0.0.81:9000; server 10.0.0.82:9000; server 10.0.0.83:9000; } server { listen 9000; proxy_pass backends; } }
   • Cstream { upstream backends { server 10.0.0.81:9000; server 10.0.0.82:9000; server 10.0.0.83:9000; } server { listen 9000; proxy_pass backends; } }
   • Dstream { upstream backends { server 10.0.0.81:9000; server 10.0.0.82:9000; server 10.0.0.83:9000; } server { listen 9000; proxy_pass backends; least_conn; } }
