Your company has a main office and three branch offices. Each office is configured as a
separate Active Directory site that has its own domain controller.
You disable an account that has administrative rights.
You need to immediately replicate the disabled account information to all sites.
What are two possible ways to achieve this goal? (Each correct answer presents a complete
solution. Choose two.)

A.
From the Active Directory Sites and Services console, configure all domain controllers as
global catalog servers.

B.
From the Active Directory Sites and Services console, select the existing connection
objects and force replication.

C.
Use Repadmin.exe to force replication between the site connection objects.

D.
Use Dsmod.exe to configure all domain controllers as global catalog servers.

How to force replication of Domain Controllers From time to time its necessary to kick off AD
replication to speed up a task you may be doing, or just a good too to check the status of
replication between DC’s.
Below is a command to replicate from a specified DC to all other DC’s.
Repadmin /syncall DC_name /Aped By running a repadmin /syncall with the /A(ll partitions)
P(ush) e(nterprise, cross sites) d(istinguished names) parameters, you have duplicated
exactly what Replmon used to do in Windows 2003, except that you did it in one step, not

many.And with the benefit of seeing immediate results on how the operations are
proceeding.
If I am running it on the DC itself, I don’t even have to specify the server name.
