When would a technician use delegation vs a stub zone or forwarding? Please reply when you have the chance.

Hi @dewitsc 

You use forwarding when you want to forward all DNS queries to another DNS server for resolution. This can be an external DNS server like a public one 4.2.2.2.

Use delegation when you want to delegate a subdomain to another DNS server. This can be when having a child domain like child.domain.com

Use stub zones when you want to create a lightweight copy of a zone to efficiently locate authoritative DNS servers for that zone.
