Quick Answer
The answer is the `show mpls forwarding-table vrf <name>` command, as it provides the most complete information for verifying MPLS forwarding entries for a specific VRF. This command displays the label forwarding information base (LFIB) for that VRF, showing both the inbound label assigned locally and the outbound label used for forwarding, along with the next-hop and outgoing interface. On the Cisco SPCOR / CCNP Service Provider Core 350-501 exam, this question tests your ability to distinguish between control-plane label bindings and the actual data-plane forwarding table—a common trap is to confuse `show bgp vpnv4 unicast all labels` (which only shows BGP-assigned labels) or `show ip cef vrf` (which lacks MPLS label details) with the correct forwarding verification command. Remember the memory tip: "For forwarding, you need the full LFIB—so think 'mpls forwarding-table vrf' to see labels in action, not just in theory."
This 350-501 practice question tests your understanding of architecture. 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.
An SP is managing a large MPLS network and needs to verify the MPLS forwarding entries for a specific VRF. Which command provides the most complete information for the VRF?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
show ip cef vrf <name>
Why wrong: This shows IP CEF entries but not MPLS label information.
show mpls forwarding-table vrf <name>
Shows the complete LFIB for the VRF with inbound and outbound labels.
show mpls vrf <name>
Why wrong: This command does not exist in Cisco IOS-XE.
show bgp vpnv4 unicast all labels
Why wrong: Displays BGP label assignments, but not the actual forwarding table.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
show mpls forwarding-table vrf <name>
Option D is correct because 'show mpls forwarding-table vrf <name>' displays the label forwarding table for the VRF, including inbound and outbound labels. Option A is wrong because 'show ip cef vrf' shows CEF table, not MPLS labels. Option B is wrong because 'show bgp vpnv4 unicast all labels' shows BGP label bindings, not the forwarding table. Option C is wrong because 'show mpls vrf' is not a valid command.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
show ip cef vrf <name>
Why it's wrong here
This shows IP CEF entries but not MPLS label information.
show mpls forwarding-table vrf <name>
Why this is correct
Shows the complete LFIB for the VRF with inbound and outbound labels.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
This shows IP CEF entries but not MPLS label information.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 350-501 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.
