NSE7 Troubleshooting and Diagnostics Practice Question
You are troubleshooting BGP route advertisement issues. Which THREE debug commands would be useful to identify why a route is not being advertised to a neighbor? (Choose three.)
⚠ Common exam trap
A common mix-up: candidates confuse 'received-routes' (inbound) with 'advertised-routes' (outbound) and think a summary command provides enough detail to diagnose per-neighbor advertisement issues.

Correct answer & explanation
✓
diagnose debug router bgp <neighbor>
The 'diagnose debug router bgp <neighbor>' command enables real-time debugging of BGP events for a specific neighbor, allowing you to see why a route is being filtered or not advertised (e.g., due to prefix-list, AS-path, or next-hop unreachable issues). This is a Fortinet-specific debug command that provides granular insight into the BGP decision process for that neighbor.
