Your network contains an Active Directory forest named corp.contoso.com. All servers run Windows Server 2012 R2.
The network has a perimeter network that contains servers that are accessed from the Internet by using the contoso.com namespace.
The network contains four DNS servers. The servers are configured as shown in the following table.

All of the servers on the perimeter network use Server1 and Server2 for name resolution.
Additional DNS servers will be added to te corp.contoso.con during the next year.

Suggested Answer:
A Stub Zones allows an organization to resolve names to a private namespace or speed up name resolution to a public name space without the use of Conditional

DNS Stub Zones in each domain will be configured to forward request for the other organization name space to a DNS server that is authoritative. All other names needing resolved will use the default name resolution method.
