Your network contains a domain controller that runs Windows Server 2008 R2.
You run the following command on the domain controller:
dsamain.exe C dbpath c:\$SNAP_201006170326_VOLUMEC$\Windows\NTDS\ntds.dit C
ldapport 389 -allowNonAdminAccess
The command fails.
You need to ensure that the command completes successfully.
How should you modify the command?

A.
Change the value of the -dbpath parameter.

B.
Include the path to Dsamain.

C.
Change the value of the -ldapport parameter.

D.
Remove the CallowNonAdminAccess parameter.

Use the AD DS database mounting tool to load the snapshot as an LDAP server.
dsamain -dbpath c:\$SNAP_datetime_VOLUMEC$\windows\ntds\ntds.dit -ldapport
portnumber

Be sure to use ALL CAPS for the -dbpath value and use any number beyond 40,000 for the –
ldapport value to ensure that you do not conflict with AD DS.
Also note that you can use the minus (–) sign or the slash (/) for the options in the command.
