Command-Line Tools for Network Troubleshooting

A.

The command-line tool that should be used to troubleshoot the scenario where a customer is unable to access wired network resources, shared drives, printers, or the Internet is the Ping tool.

Ping is a network utility tool that is used to test the connectivity between two devices on a network. It sends an Internet Control Message Protocol (ICMP) echo request to a specific IP address or domain name and waits for a response.

By using Ping, you can check whether the computer can communicate with other devices on the network. If the Ping test is successful, it means that the network connection between the computer and other devices is working properly. If the Ping test fails, it indicates that there is a problem with the network connection, such as a misconfigured IP address, a faulty network cable, or a network device failure.

The other command-line tools mentioned in the answers are:

• hwconfig: This is not a valid command-line tool. It is possible that the answer meant to refer to the "ipconfig" tool, which is used to display the IP configuration settings of a Windows computer.
• Nbtstat: This is a tool that is used to display the NetBIOS over TCP/IP (NBT) protocol information for a Windows computer. It can be used to troubleshoot name resolution issues on the network.
• Nslookup: This is a tool that is used to perform DNS (Domain Name System) lookups to resolve domain names to IP addresses. It can be used to troubleshoot DNS-related issues on the network.

While hwconfig and Nslookup can be useful for troubleshooting specific issues, Ping is the most general-purpose tool and is the best choice for troubleshooting connectivity issues.
