I get this in most interviews to explain how to troubleshoot replication lag after you have already identified if this is a network problem or other (IO thread vs SQL thread). Can someone please help to describe some of the steps or process they take to troubleshoot replication lag, and also broken replication. How to broken replication without having to recreate the replica.
