350-401 Practice Question: Runs the following command on Router R1: R1# show…

A network engineer runs the following command on Router R1:

R1# show bgp ipv4 unicast 192.168.1.0/24

BGP routing table entry for 192.168.1.0/24, version 15 Paths: (1 available, best #1, table default) Advertised to update-groups: 1 Refresh Epoch 1 65050, (received & used)

10.0.1.2 from 10.0.1.2 (10.0.0.2)

Origin IGP, metric 0, localpref 100, weight 0, valid, external, best rx pathid: 0, tx pathid: 0x0

Based on this output, what can be concluded?

⚠ Common exam trap

Cisco often tests the distinction between 'valid' and 'best' — candidates may incorrectly assume that an external route is automatically invalid or that 'external' implies a problem, but the output clearly shows the route is both valid and best.

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 route is from AS 65050 and is the best path.

The output shows the BGP table entry for 192.168.1.0/24 with path 65050, and the line 'valid, external, best' confirms that this route is from AS 65050 and is selected as the best path. The 'best' keyword in the status flags directly indicates that this path is the best among all available paths for this prefix.

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 route was learned from an internal BGP peer.

    Why it's wrong here

    The output says 'external', meaning it is an eBGP route, not iBGP.

  • The route is from AS 65050 and is the best path.

    Why this is correct

    The AS_PATH shows 65050, and the path is marked as 'best'.

  • The route has a local preference of 0.

    Why it's wrong here

    The local preference is 100, not 0.

  • The route is not valid because it is external.

    Why it's wrong here

    The route is marked as 'valid', so it is valid.
