The answer is show vrf, show ip route vrf BLUE, and show ip interface vrf BLUE. These three commands are the standard verification tools for VRF-Lite because they respectively display the VRF definitions with route distinguishers and route targets, the VRF-specific routing table, and the interfaces assigned to a given VRF. On the Cisco CCNP ENARSI 300-410 exam, this topic tests your ability to isolate and troubleshoot multi-VRF environments without MPLS, and a common trap is confusing show vrf interfaces with the correct show ip interface vrf command—the latter is the only one that confirms interface-to-VRF binding. Remember the memory tip: “V, R, I” for VRF list, Route table, and Interface assignment—if you can recall those three, you’ll avoid the invalid options like show vrf detail or show vrf interfaces.
300-410 VRF-Lite Practice Question
This 300-410 practice question tests your understanding of vrf-lite. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE commands can be used to verify VRF-Lite configuration and operation on a Cisco IOS-XE router? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
show vrf
Common verification commands for VRF-Lite include: 'show vrf' to list VRFs and their RD/RT, 'show ip route vrf <name>' to display the VRF-specific routing table, and 'show ip interface vrf <name>' to show interfaces assigned to a VRF. Option A is correct. Option B is correct. Option C is correct. Option D is incorrect because 'show ip vrf interfaces' is the correct command, not 'show vrf interfaces'. Option E is incorrect because 'show vrf detail' is not a valid command; the correct command is 'show vrf' or 'show vrf <name>'.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
show vrf interfaces
Why it's wrong here
Incorrect. The correct command is 'show ip vrf interfaces'. 'show vrf interfaces' is not a valid IOS command.
✗
show vrf detail
Why it's wrong here
Incorrect. There is no 'show vrf detail' command. Use 'show vrf' or 'show vrf <name>' for details.

TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
