The local AS number being 100 seems straightforward, but I’m a bit confused about the significance of the AS-path and how it affects route selection.

I remember that the local BGP router ID is usually important for identifying the router, so I believe option B is true.

I feel like the Local_Pref value should influence route selection, but since it says "pref-val 0," I'm not sure if that means it won't be selected.
