An administrator suspects that a gateway machine on their network has failed; the administrator is unsure which machine is the problem. Which of the following commands will help locate the problem mac

`ps` lists active processes on the local machine and is unrelated to network path diagnostics.

`netstat` displays network connections, routing tables, and interface statistics on the local machine, but it doesn't trace the path to a remote host.

`nslookup` (or `dig`) is used for DNS queries to resolve hostnames to IP addresses or vice versa, not for network path diagnostics.

`ifconfig` (or `ip addr`) displays network interface configuration on the local machine, not for diagnosing issues with remote gateways.

The `traceroute` command maps the path packets take to reach a destination by showing each intermediate hop (router/gateway) and the time it takes to reach it. If a gateway machine has failed, `traceroute` will show where the packets stop or encounter significant delays, pinpointing the problematic device on the network path.
