350-401 BGP Practice Question

This 350-401 practice question tests your understanding of bgp. 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 R1:

R1# show bgp ipv4 unicast 192.168.1.0

BGP routing table entry for 192.168.1.0/24, version 10 Paths: (2 available, best #2, table default) Advertised to update-groups: 1 Refresh Epoch 1 Local

10.0.0.2 from 10.0.1.2 (10.0.0.2)

Origin IGP, metric 0, localpref 100, valid, internal rx pathid: 0, tx pathid: 0x0 Local, (received & used)

10.0.0.3 from 10.0.1.3 (10.0.0.3)

Origin IGP, metric 0, localpref 200, valid, internal, best rx pathid: 0, tx pathid: 0x0

Based on this output, what can be concluded?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "best"

    Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.

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

✓

The path from 10.0.1.3 is preferred because of a higher local preference.

The output shows two BGP paths for 192.168.1.0/24, both with Origin IGP and metric 0. The path from 10.0.1.3 has a local preference of 200, while the path from 10.0.1.2 has a local preference of 100. BGP selects the path with the highest local preference as the best path, making the path from 10.0.1.3 the best (marked as 'best' in the output).

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

  • ✗

    The path from 10.0.1.2 is the best path because it is received first.

    Why it's wrong here

    BGP does not select best path based on order received. The best path is path #2 from 10.0.1.3 due to higher local preference.

  • ✓

    The path from 10.0.1.3 is preferred because of a higher local preference.

    Why this is correct

    Local preference is 200 for path #2 (from 10.0.1.3) versus 100 for path #1. Higher local preference is preferred in BGP best path selection.

    Clue confirmation

    The clue word "best" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Both paths are from external BGP peers.

    Why it's wrong here

    Both paths show 'internal' in the output, indicating they are iBGP routes, not eBGP.

  • ✗

    The path from 10.0.1.2 is marked as best because it has a lower metric.

    Why it's wrong here

    Both paths have metric 0. The best path is determined by local preference, not metric.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the BGP best path selection order, and the trap here is that candidates may confuse local preference with MED or assume that the first received route is preferred, when in fact local preference is evaluated much earlier in the decision process.

Trap categories for this question

  • Command / output trap

    Both paths show 'internal' in the output, indicating they are iBGP routes, not eBGP.

Detailed technical explanation

How to think about this question

Local preference is a well-known mandatory BGP attribute used to influence outbound traffic from an AS; it is propagated throughout the entire AS via iBGP updates. In the BGP best path selection algorithm, local preference is the second step after preferring a path with a higher weight (Cisco-specific), making it a critical tool for traffic engineering within a single AS. A common real-world scenario is setting higher local preference on routes learned from a primary upstream provider to prefer that link over a backup.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • 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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
