Exam N10-009 topic 1 question 97 discussion

The correct answer is: B. netstat Explanation: The netstat command is used to check the listening ports and active network connections on a system. Since the web server process is running and users can ping the server, the issue might be related to whether the web server is properly listening on the expected port (e.g., TCP port 80 for HTTP or TCP port 443 for HTTPS). Running netstat (or its modern replacement, ss) can quickly verify if: The web server is listening on the expected port. The service is bound to the correct IP address or network interface.

C. tcpdump Explanation: Since users can ping the server but cannot access the web server via a browser, it suggests that the server's network interface is operational (because it responds to ICMP ping requests), but there may be an issue with the web server's network traffic or its ability to respond to HTTP requests. tcpdump is a network packet analyzer that can capture and display packets on the network. Running tcpdump on the server will help the administrator observe if the server is receiving the HTTP requests (on port 80 for HTTP or port 443 for HTTPS) from users and whether the server is responding to those requests. This would be the first step to identify if the issue lies with the server not receiving or not responding to web traffic.

Check the netstat first. Even if the demon is running, there is no port mapping or correcrt port number when checking netstat. .

The netstat command helps verify if the server is listening on the correct port (e.g., 80 or 443 for HTTP/HTTPS)
