Which tool should you use?

Netdom

B.
Ntdsutil

C.
Dsmod

D.
Dsamain

Explanation:
* To create or delete an application directory partition Open Command Prompt.
Type:ntdsutil
At the ntdsutil command prompt, type:domain management
At the domain management command prompt, type:connection
At the server connections command prompt, type:connect to server ServerName
At the server connections command prompt, type:quit
At the domain management command prompt, do one of the following:
* partition management
Manages directory partitions for Active Directory Domain Services (AD DS) or Active Directory
Lightweight Directory Services (AD LDS).
This is a subcommand of Ntdsutil and Dsmgmt. Ntdsutil and Dsmgmt are command-line tools that

are built into Windows Server 2008 and Windows Server 2008 R2.
/ partition management create nc %s1 %s2
Creates the application directory partition with distinguished name %s1, on the Active Directory
domain controller or AD LDS instance with full DNS name %s2. If you specify “NULL” for %s2, this
command uses the currently connected Active Directory domain controller. Use this command only
with AD DS. For AD LDS, use create nc %s1 %s2 %s3.
Note:
* An application directory partition is a directory partition that is replicated only to specific domain
controllers.
A domain controller that participates in the replication of a particular application directory partition
hosts a replica of that partition.
