    A secondary zone is a read-only copy of a primary zone. Basically, you can use them to offload some of DNS traffic like queries, from areas in your network that are more heavily used. If your primary zone were to become unavailable, the secondary zone could provide name resolution until the primary zone is restored.

    Stub zones only store the name server, SOA, and A records. They can be used to minimize the network traffic. Stub zones are dynamic, so they can be used to update records for the parent zones.
