In a troubleshooting scenario, which command can be used to check the ping response from a default gateway?

Using the ping command is an effective way to check the connectivity to a default gateway. This command sends Internet Control Message Protocol (ICMP) echo request packets to the specified network device, such as the default gateway, and listens for echo reply packets. This process helps determine if the device is reachable over the network and provides information about the round-trip time of the packets. If the default gateway responds to the ping, it confirms that both the network path to the gateway is functioning and that the gateway is operational.

The other commands serve different purposes. Tracert is used to trace the route packets take to reach a destination, which helps identify potential points of failure along the path but does not directly check the response from a gateway. Ipconfig provides information about the IP configuration of the system, including the default gateway, but does not test connectivity. Finally, nslookup is used for querying DNS records and does not relate to pinging or connectivity checks. Therefore, using ping is the most appropriate method to verify the response from a default gateway.
