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 AS 65001 is the best path due to its higher local preference of 100.
The show bgp ipv4 unicast command displays BGP paths for a specific prefix. Here, two paths are available: one from AS 65001 with local preference 100, and one from AS 65002 with local preference 50. The path with higher local preference (100) is selected as best.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Both paths are equally preferred, and BGP load-balances traffic to 192.168.1.0/24.
Why it's wrong here
Only the best path is used for forwarding; load-balancing requires multiple best paths, which is not shown.
- ✗
The path from AS 65002 is preferred because it has a lower local preference.
Why it's wrong here
Higher local preference is preferred. The path with localpref 100 is best.
- ✓
The path from AS 65001 is the best path due to its higher local preference of 100.
Why this is correct
Local preference is a weight attribute; higher values are preferred. The path with localpref 100 is selected as best.
- ✗
The path from AS 65002 is the best path because it has a lower metric.
Why it's wrong here
Both paths have metric 0. Local preference determines best path here.
