Set the DNS Server1(TN)'s address on NUT as above mentioned Network Topology.
In order to send the query for A type of AP Server1(TN):A.example.com to the DNS Server1(TN) with OPT RR(1024 bytes), NUT is configured.
This test sequence is following.

1. Standard query for A type with OPT RR must be based on above Verification Points. *OPT RR must be one.
If NUT has cache function, clear the cache.
