You have an Active Directory forest named csmtech.local and two Active Directory domains in the forest named csmpub.local and csmsales.local. You want the DNS servers in each domain to be able to handle DNS queries from client computers for any of the other domains. DNS servers in the csmtech.local and csmpub.local domains should be authoritative for their own domains and the csmsales.local domain. However, DNS servers in csmsales.local should be authoritative only for csmsales.local.
How should you set up the DNS servers and zones to handle this situation? Explain how the DNS servers in each domain should be configured with zones. Be sure to include information about replication scope and zone types.
