Question
Your network contains an Active Directory Domain Services (AD DS) forest. The forest contains the servers shown in the following table.
| Name | In domain | Description |
|---|---|---|
| Server1 | contoso.com | Domain controller, DNS server |
| Server2 | contoso.com | Domain controller, DNS server |
| Server3 | contoso.com | DNS server |
| Server4 | east.contoso.com | Domain controller, DNS server |
| Server5 | east.contoso.com | DNS server |
On Server1, you create a DNS zone named Zone1.com as shown in the following exhibit.
To which DNS servers is Zone1.com replicated?
- A. Server2 only Correct
- B. Server2 and Server3 only
- C. Server2 and Server4 only
- D. Server2, Server3, and Server4 only
- E. Server2, Server3, Server4, and Server5
Explanation
Zone1.com is an Active Directory-integrated zone, and its replication scope is set to All DNS servers in this domain. Its data is stored in the DomainDnsZones application directory partition of contoso.com, and that partition replicates only to domain controllers in contoso.com that run the DNS Server role. Server2 is the only other domain controller in contoso.com that runs DNS, so the zone replicates only to Server2. Server3 is a DNS server in contoso.com but not a domain controller, so it holds no copy of the Active Directory database and cannot host an AD-integrated zone. Server4 and Server5 are in east.contoso.com, outside the selected domain scope. Only the All DNS servers in this forest scope would include Server4, and even then Server5 would be left out because it is not a domain controller.
