Which command would you use to view detailed network information for TCP, UDP, IP, and ICMP protocols?

• A. ifconfig
• B. ethtool
• C. traceroute
• D. netstat

Answer: (D)

Choosing the command to view detailed network information for the TCP, UDP, IP, and ICMP protocols can be effectively addressed with the use of netstat. This command is particularly useful because it provides comprehensive details about the network connections currently in use, including active connections, routing tables, interface statistics, and protocol statistics. netstat allows you to view the state of TCP connections (whether they are established, listening, or closed), which is crucial for troubleshooting network issues. Additionally, it can display UDP connection information, providing insights into the packets being sent or received without establishing connections like TCP. While the other commands listed have their specific purposes, they do not offer the same level of detail across all the mentioned protocols: - ifconfig is primarily used to configure network interfaces and retrieve configuration details for those interfaces rather than providing detailed protocol-level insights. - ethtool focuses on Ethernet device settings and statistics, which does not extend to detailed views of network protocols like TCP, UDP, or ICMP. - traceroute aids in determining the path packets take across the network but does not provide detailed information about the protocols themselves or the state of active connections. Therefore, netstat is the most suitable command for obtaining extensive network information related to TCP, UDP, IP,
