LPIC-1 Essential System Services and Networking Practice Question
A technician is troubleshooting network connectivity. The server's IP is 192.168.1.10/24, and the gateway is 192.168.1.1. The server can ping the gateway but cannot ping 8.8.8.8. Which command is most appropriate to check if the default route is configured?
⚠ Common exam trap
Test-takers frequently assume a successful ping to the gateway implies a default route exists, but the gateway being reachable does not mean the server has a route to forward traffic beyond the local subnet.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
route -n
The `route -n` command displays the kernel IP routing table without resolving hostnames, showing the default route (destination 0.0.0.0) and its gateway. Since the server can ping the gateway but not 8.8.8.8, the issue is likely a missing or incorrect default route, which `route -n` directly reveals.
