Correct answer & explanation
ping: Tests network connectivity to a remote host
Ping tests connectivity, netstat shows network statistics, ifconfig configures interfaces, nslookup performs DNS queries. Traceroute traces paths, and system IP is better shown by ifconfig or hostname -I.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
ping: Tests network connectivity to a remote host
Why this is correct
ping sends ICMP echo requests to verify reachability and measure round-trip time.
netstat: Displays network connections, routing tables, and interface statistics
Why this is correct
netstat provides information about active network connections and network protocols.
ifconfig: Configures or displays network interface parameters
Why this is correct
ifconfig is used to assign IP addresses, netmasks, and other interface settings.
nslookup: Queries DNS servers for hostname or IP address information
Why this is correct
nslookup resolves domain names to IP addresses and vice versa.
ping: Used to trace the route packets take to a destination
Why it's wrong here
This describes traceroute, not ping.
netstat: Used to display the IP address of the system
Why it's wrong here
While netstat can show interface IPs, its primary purpose is broader; ifconfig or hostname -I is more direct.
