I've got a little lost with DNS Clustering so would appreciate some feedback.

At the moment I have:

cPanel A (ns1.mydomain.com)
cPanel B (ns2.mydomain.com)
DNS Only (ns3.mydomain.com)

1) Is it optimal to have them all running as nameservers serving zones for both cPanel A and B?

2) How should they be configured with each-other so that a Zone edited on either cPanel A or B syncs to each-other as well as the DNS Only server?

Unless I'm missing something, this is a very straight forward setup:

cPanel A -> Sync Changes cPanel B
cPanel A -> Sync Changes DNS Only

cPanel B -> Sync Changes cPanel A
cPanel B -> Sync Changes DBS Only

If you were to add cPanel C it would look like:

cPanel C -> Sync Changes cPanel A
cPanel C -> Sync Changes cPanel B
cPanel C -> Cync Changes DNS Only
