Difficulty: EasyUtilizing Command-Line Network Troubleshooting Utilities

Match each command-line network utility on the left with its primary diagnostic function on the right.

  • pingVerifies Layer 3 reachability to a remote host and measures round-trip time using ICMP Echo Requests.
  • tracertDisplays the hop-by-hop router path and packet delivery latency to a target destination.
  • nslookupQueries DNS servers to test name resolution and inspect domain resource records.
  • netstatDisplays active TCP/UDP connections, listening ports, and protocol statistics on the local system.

Answer

ping matches reachability verification; tracert matches hop-by-hop path tracing; nslookup matches DNS query testing; netstat matches active connections and listening ports inspection.
Each utility targets a distinct diagnostic domain: ping tests basic ICMP reachability; tracert maps route paths and hop latencies; nslookup queries DNS infrastructure; and netstat inspects active protocol connections and listening ports on the local machine.

Step-by-Step Solution

1
Identify the basic reachability tool
ping sends ICMP requests to check if a remote host is reachable.
ping is the primary tool for testing Layer 3 ICMP echo response.
2
Identify the route tracing tool
tracert identifies intermediate router hops and latency along a path.
tracert increments TTL values to discover each router along the path to a destination.
3
Identify the name resolution diagnostic tool
nslookup queries DNS servers directly.
nslookup evaluates DNS record lookups and name resolution issues.
4
Identify the protocol and session statistics tool
netstat lists active connections and open ports on the local endpoint.
netstat provides socket-level information for active TCP/UDP sessions.
