Which utility would you use to troubleshoot network connectivity issues?

Using the Ping utility is an effective approach to troubleshoot network connectivity issues because it operates by sending Internet Control Message Protocol (ICMP) Echo Request messages to a destination IP address and waiting for a response. This process helps determine whether the target device is reachable over the network. If the ping command returns a response, it indicates that the network connection between the source and destination is functioning correctly. If it fails, further investigation is needed to identify where the connectivity issue may lie, whether it be a problem with the local network, a firewall blocking connectivity, or issues with the destination server itself.

In contrast, FTP is primarily a file transfer protocol and does not provide tools for diagnosing connectivity issues. SSH is a secure protocol for managing network devices and does not inherently check connectivity, but rather allows encrypted command line access. Wake-on-LAN is a network standard used to turn on devices remotely, which is unrelated to troubleshooting existing connectivity problems.
