Which of these troubleshooting tasks would be accomplished by pinging 127.0.0.1?
A) Validate that the default gateway is responding
B) Confirm that the local IP stack is working properly
C) Test Windows Update connectivity
D) Determine round-trip time to a site across the Internet
E) Identify open ports on the local device
F) It would be easier to troubleshoot if I connected the power
The answer: B) Confirm that the local IP stack is working properly
The 127.0.0.1 address is the local loopback for the device, and pinging the loopback address can confirm that your local IP stack and operating system configuration is working properly. The next steps would most likely be to ping the IP address on your network adapter and then another device on your local subnet, such as your default gateway.
