What command do you use to test a system’s IPv4 protocol stack?
A.
ping 127.0.0.1
B.
ping self
C.
ping 255.255.255.255
D.
ping defaultgateway
Explanation:
Working with Ipconfig and PingWhen you ping 127.0.0.1, the results do not include any hostname resolution information. This is the best way to ping the local host when testing IPv4.
When pinging 127.0.0.1, no traffic is placed on the network segment; instead, all traffic is kept inside the computer or local loopback.
