Which tool is commonly used for network troubleshooting?

• A. Word processor
• B. Ping command
• C. Spreadsheet application
• D. Graphic design software

Answer: (B)

The ping command is a fundamental tool used for network troubleshooting because it tests the reachability of a host on an Internet Protocol (IP) network. When a user executes a ping command, it sends Internet Control Message Protocol (ICMP) echo request packets to the target IP address and listens for responses. This helps determine if the target is accessible and measures the round-trip time for messages sent from the originating host to the destination and back. Network administrators regularly use the ping command to diagnose connectivity issues, check if a device is online, and evaluate the quality of the network connection. This tool is essential for troubleshooting because it provides immediate feedback on the status of network devices, serving as a first step in the diagnostic process. The other options listed—word processors, spreadsheet applications, and graphic design software—are not designed for network diagnostics and serve different purposes unrelated to network troubleshooting.
