Correct answer & explanation
ping: Tests network connectivity to a remote host
Common CLI tools for network troubleshooting: ping tests reachability, traceroute shows the path, nslookup resolves DNS names. Confusing these functions is a typical mistake.
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
Correct: ping sends ICMP echo requests to test reachability and round-trip time.
traceroute: Traces the route packets take to a destination
Why this is correct
Correct: traceroute shows each hop along the path to the target IP.
nslookup: Queries DNS to resolve domain names to IP addresses
Why this is correct
Correct: nslookup is used to diagnose DNS resolution issues.
ping: Traces the route packets take to a destination
Why it's wrong here
Incorrect: this describes traceroute, not ping. Ping tests connectivity, not path.
traceroute: Queries DNS to resolve domain names to IP addresses
Why it's wrong here
Incorrect: traceroute maps the network path; DNS resolution is done by nslookup.
nslookup: Tests network connectivity to a remote host
Why it's wrong here
Incorrect: nslookup resolves DNS; testing connectivity is the role of ping.
