Your network contains an Active Directory domain named contoso.com.
The domain contains a main office and a branch office.
An Active Directory site exists for each office.
All domain controllers run Windows Server 2012. Thedomain contains two domain controllers.
The domain controllers are configured as shown in the following table.
DC1 hosts an Active Directory-integrated zone for contoso.com.
You add the DNS Server server role to DC2.
You discover that the contoso.com DNS zone fails toreplicate to DC2.
You verify that the domain, schema, and configuration naming contexts replicate from DC1 to DC2.
You need to ensure that DC2 replicates the contoso.com zone by using Active Directory replication.
Which tool should you use?
A.
Active Directory Domains and Trusts
B.
repadmin
C.
ntdsutil
D.
Active Directory Users and Computers
It’s C. Ntdsutil
I think its B, Repadmin.
ntdsutil.exe: pa ma
Add NC Replica %s1 %s2
Repadmin.exe helps administrators diagnose Active Directory replication problems between domain controllers running Microsoft Windows operating systems.
To use Repadmin.exe, you must run the ntdsutil command from an elevated command prompt. To open an elevated command prompt, click Start, right-click Command Prompt, and then click Run as administrator.
You can use Repadmin.exe to view the replication topology, as seen from the perspective of each domain controller. In addition, you can use Repadmin.exe to manually create the replication topology, to force replication events between domain controllers, and to view both the replication metadata and up-to-dateness vectors (UTDVECs). You can also use Repadmin.exe to monitor the relative health of an Active Directory Domain Services (AD DS) forest.
