An administrator wants to use a Windows system to monitor a server that is rebooting. Which of the following commands should the administrator use to know when the NIC is back online in the server?

The ping -i 240 command sets the Time To Live (TTL) value of the ICMP packets to 240, which is unrelated to continuously monitoring a server for connectivity after a reboot.

The ping -t command sends continuous ICMP echo requests to the target host until interrupted, allowing the administrator to immediately see when the server's NIC comes back online and starts responding.

The ping -a command resolves addresses to hostnames, which is not the primary function for monitoring when a NIC is back online.

The ping -w 240 command sets the timeout for each ping request to 240 milliseconds, which determines how long to wait for a reply, but it does not send continuous pings.
