Exhibit

Refer to the exhibit.

Router# show ip bgp
BGP table version is 123, local router ID is 10.1.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
              r RIB-failure, S Stale, m multipath, b backup-path, f RT-Filter,
x best-external, a additional-path, c RIB-compressed,
Origin codes: i - IGP, e - EGP, ? - incomplete

Refer to the exhibit. Which of the following is true about the BGP table?

⚠ Common exam trap

Cisco often tests the misconception that a shorter AS path always determines the best path, but here both paths have equal AS path length, so candidates must look at other attributes like origin code or IGP metric to determine why one path is preferred.

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 prefix 192.168.3.0/24 has two paths, with the best path selected based on some attribute.

The exhibit shows two paths for prefix 192.168.3.0/24: one via 10.4.4.4 with AS path 300 400 and one via 10.5.5.5 with AS path 300 500. BGP selects the best path based on a sequence of attributes (e.g., weight, local preference, AS path length, origin code, MED, etc.). Option B is correct because the prefix has two paths and BGP will choose one as best based on these attributes.

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 to 192.168.3.0/24 with path 300 400 has an origin of IGP.

    Why it's wrong here

    Incorrect. The origin is incomplete ('?').

  • The prefix 192.168.3.0/24 has two paths, with the best path selected based on some attribute.

    Why this is correct

    Correct. There are two entries, one is best.

  • The prefix 192.168.2.0/24 is not the best path because it has a lower local preference.

    Why it's wrong here

    Incorrect. It has local preference 150, which is higher than 100.

  • The route to 192.168.3.0/24 via 10.4.4.4 is the best path because it has a shorter AS path.

    Why it's wrong here

    Incorrect. The best path is via 10.5.5.5, which has longer AS path.
