300-410 Practice Question: Which THREE commands are used to troubleshoot…

Which THREE commands are used to troubleshoot VRF-Lite connectivity issues on a Cisco IOS-XE router? (Choose THREE.)

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

✓

show ip route vrf <vrf-name>

These three commands provide essential troubleshooting information: 'show ip route vrf' displays the VRF routing table, 'ping vrf' tests connectivity from within a VRF, and 'show vrf' shows VRF status and interfaces. The other options: 'traceroute' without VRF context may not work correctly, and 'show ip cef' without VRF shows global CEF, not VRF-specific.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    show ip route vrf <vrf-name>

    Why this is correct

    Shows the routing table for the specified VRF, critical for verifying route presence.

  • ✓

    ping vrf <vrf-name> <destination>

    Why this is correct

    Sends ICMP echo requests from within the VRF context, testing end-to-end connectivity.

  • ✓

    show vrf

    Why this is correct

    Displays all VRFs and their associated interfaces, confirming correct configuration.

  • ✗

    traceroute <destination>

    Why it's wrong here

    Without the VRF keyword, traceroute uses the global routing table and may not work for VRF destinations.

  • ✗

    show ip cef

    Why it's wrong here

    Shows the global CEF table, not VRF-specific; use 'show ip cef vrf <vrf-name>' instead.
