A diagnostic tool reports a "host seems down" event for a server with an IP address of 192.168.47.44. Which of the following commands should the administrator use to confirm the host down event?
The ping -c 1 192.168.47.44 command sends one ICMP echo request to the specified host to check its availability. If the host is down, there will be no response. This is the quickest way to confirm if a host is reachable. nmap -Pn can also be used to check a host status, but ping is faster and lighter.
