Difficulty: EasyUtilizing Command-Line Network Troubleshooting Utilities

A network technician is troubleshooting a workstation that cannot access external web services. Arrange the command-line network utilities in the correct logical sequence of execution to systematically isolate the issue from the local host configuration to external path reachability and name resolution.

  1. 1ipconfig /all
  2. 2ping 192.168.1.1
  3. 3tracert 8.8.8.8
  4. 4nslookup www.example.com

Answer

The correct logical order of execution is: 1. ipconfig /all, 2. ping 192.168.1.1, 3. tracert 8.8.8.8, 4. nslookup www.example.com.
A structured troubleshooting approach starts on the local machine with ipconfig /all to verify interface settings, moves to testing the local gateway with ping, extends to remote internet path checking via tracert, and concludes with domain name resolution verification via nslookup.

Step-by-Step Solution

1
Run ipconfig /all to examine local host IP settings.
Confirms the host has a valid IP address and identifies the configured default gateway.
Troubleshooting must begin by verifying that the local adapter is properly configured and functional.
2
Run ping against the default gateway IP address (192.168.1.1).
Confirms local network interface communication and switch port connectivity.
Verifying local gateway reachability ensures local network segment connectivity works before testing remote paths.
3
Run tracert to a known public IP address (8.8.8.8).
Maps the hop-by-hop path across external routers to isolate routing failures.
Testing IP routing to an external IP ensures IP packets can exit the local network independently of DNS name resolution.
4
Run nslookup for the target domain name (www.example.com).
Tests whether the configured DNS server can resolve domain names to IP addresses.
Name resolution testing should occur after basic IP connectivity and remote path reachability have been established.

Key Concept

Standard systematic CLI network troubleshooting methodology progresses from local host configuration verification up through local gateway ping, remote path tracing, and application domain name resolution.
