Error Symptoms:

Added DNS host record to cPanel virtual server and synchronized to all name servers but it cannot be queried. Problem was described at
https://forums.cpanel.net/threads/dns-records-are-not-synchronizing.638673/
This thread was started by Teo En Ming.

Cause:

My DNS Cluster was configured correctly and also synchronizing correctly as well.
However, there are THREE (3) zone files which contain the same domain name teo-en-ming-corp.com, which causes great confusion for the BIND DNS server.
As a result, DNS host record which is added and synchronized successfully could not be queried.
There should be only one zone file for one domain name.
