While trying to configure an existing DNS server to be a secondary server
for the domain mydomain.com, you receive the following error:

Dec 25 08:12:52 frogstar named[1531]: transfer of ‘mydomain.com/IN’ from 192.168.10.11#53: failed
while receiving responses: REFUSED

SOA record on the secondary server

B.
allow-query entry on the slave server

C.
allow-query entry on the master server

D.
allow-transfer entry on the master server
