Which tool should you use?

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 R2. The domain 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 to replicate 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 Sites and Services

B.
Ntdsutil

C.
DNS Manager

D.
Active Directory Domains and Trusts

Explanation:
A)
To control replication between two sites, you can use the Active Directory Sites and Services
snap- in to configure settings on the site link object to which the sites are added. By configuring
settings on a site link, you can control when replication occurs between two or more sites, and how
often
B)
Ntdsutil.exe is a command-line tool that provides management facilities for Active Directory
Domain Services (AD DS) and Active Directory Lightweight Directory Services (AD LDS).
You can use the ntdsutil commands to perform database maintenance of AD DS, manage and
control single master operations, and remove metadata left behind by domain controllers that were
removed from the network without being properly uninstalled.
C)
DNS Manager is the tool you’ll use to manage local and remote DNS Servers
D)
Active Directory Domains and Trusts is the Microsoft Management Console (MMC) snap-in that
you can use to administer domain trusts, domain and forest functional levels, and user principal
name (UPN) suffixes.

Note: If you see question about AD Replication, First preference is AD sites and services, then
Repadmin and then DNSLINT.
