I have a 3 node Windows Server 2016 DataCenter Failover Cluster with a SQL Always On Availability Group (SQL Server 2019) with no shared storage.
There are two nodes in Site1 and a third node in another remote site Site2.
Is a file share witness the best option for as a quorum witness?
Does it matter which site should the file share witness be placed in?
Does the file share witness have to be Server 2016 and up?
Also, what would happen if the file share witness server was to go offline in the above setup?
