Secondary DNS can be used not only to combine two or more servers to work together, but it can be used to have a Hidden Master server where to manage all DNS zones, records and settings and the zones and changes to be propagated automatically to a public server which will face all the DNS traffic. Such configuration allows you to protect the backend hidden server from DDoS attacks or your domain names to be served only from a fast Anycast network, so the Unicast network connection of the Hidden Master server will not affect the global speed of the domain name.
Hidden Master is a simple DNS configuration that prevents attacks on the Master DNS server. Usually, this server is not listed at the registrar or as an NS record in the DNS zone. This way, the Master DNS server is always protected, as nobody will be able to see that it exists. If something wrong happens to the Slave DNS server, there will be no impact on the Master DNS server. Optionally, it can be behind a Firewall.
