You configure an NTP server to use its local undisciplined clock and also an external server at address 192.20.20.1. Additionally, you create a fudge line:

fudge 127.127.1.0 stratum 12

Which is the purpose of the fudge line?

A.
to ensure that only servers below stratum 12 are queried

B.
to ensure that the server’s local clock is seen as a stratum 12 server

C.
to ensure that the synchronization is checked at 12:00 P.M. each day

D.
to make the xntpd daemon check the clients clock every 12 minutes
