This 350-401 practice question tests your understanding of mpls. 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.
A network engineer runs the following command on Router R9:
R9# show mpls ldp bindings 10.9.9.0 255.255.255.0
lib entry: 10.9.9.0/24, rev 10 local binding: label: 22 remote binding: lsr: 10.9.9.1:0, label: 23 remote binding: lsr: 10.9.9.2:0, label: 24 remote binding: lsr: 10.9.9.3:0, label: 25
Based on this output, how many remote LDP peers have advertised a label for the prefix 10.9.9.0/24?
1
Why wrong: There are three remote bindings.
2
Why wrong: There are three remote bindings.
3
Three remote LSRs are listed: 10.9.9.1:0, 10.9.9.2:0, and 10.9.9.3:0.
4
Why wrong: There is one local binding and three remote, so total four entries but only three remote peers.

Correct answer & explanation
3
The output shows three remote bindings from different LSRs (10.9.9.1, 10.9.9.2, 10.9.9.3), each with a different label. So three remote peers have advertised labels.
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.
1
Why it's wrong here
There are three remote bindings.
2
Why it's wrong here
There are three remote bindings.
3
Why this is correct
Three remote LSRs are listed: 10.9.9.1:0, 10.9.9.2:0, and 10.9.9.3:0.

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.
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 350-401 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.
What to study next
