1. If there are multiple Servers configured that listen on the queried port, it will check which one
   has the most specific zone for this query (longest suffix match). E.g. if there are two Servers,
   one for example.org and one for a.example.org, and the query is for www.b.example.org, it
   will be routed to the latter.

The query of www.b.example.org will be routed to the former.
I guess the query is for www.a.example.org .
