XK0-006 Troubleshooting Practice Question
An administrator needs to check the current routing table on a Linux system. Which command should be used?
⚠ Common exam trap
Candidates often confuse `ip neigh` (which shows ARP entries) with `ip route` (which shows the routing table), as both involve network path information but serve entirely different layers of the network stack.
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
✓
ip route
The `ip route` command displays the kernel routing table, showing the paths that packets take to reach network destinations. This is the standard tool on modern Linux systems for viewing and manipulating routing entries, replacing the older `route -n` command.
