PowerDNS doesn't resolve domain

[hackernewbie91]

Hi, I'm a newbie and want to learn about PowerDNS.
I have installed latest powerDNS version 4.9.x
I have setup Authoritative DNS and recursive DNS

Hostname : NS1 (192.168.10.200) as Authoritative DSN
in /etc/resolv.conf ::
nameserver 192.168.10.200

in /etc/hosts
192.168.10.200 ns1 ns1.formylab.loc

in pdns.conf
local-address = 192.168.10.200
localport =53

hostname : dns1 (192.168.10.201) as recursive DNS
I'm confuse there are two config file (recrsor.conf and recursor.yml-dist) which one should I use ?
I use recursor.yml-dist, and I have already setup some parameter like below :
forward-zone :
domain : formylab.loc
local-port: 53
more or less look like above

the issue is on recursive dns doesn't resolv domain and ext. domain as well.
it make me frustrated, please help
