Explanation:
To prepopulate the password cache for an RODC by using Active Directory Users and Computers (see step 1
below).
Administrative credentials: To prepopulate the password cache for an RODC, you must be a member of the
Domain Admins group.
Click Start, click Administrative Tools, and then click Active Directory Users and Computers.
Ensure that Active Directory Users and Computers points to the writable domain controller that is running
Windows Server 2008, and then click Domain Controllers.
In the details pane, right-click the RODC computer account, and then click Properties.
Click the Password Replication Policy tab.
Click Advanced.
Click Prepopulate Passwords.
Type the name of the accounts whose passwords you want to prepopulate in the cache for the RODC, and
then click OK.
When you are asked if you want to send the passwords for the accounts to the RODC, click Yes.
Note: You can prepopulate the password cache for an RODC with the passwords of user and computer
accounts that you plan to authenticate to it. When you prepopulate the RODC password cache, you trigger the
RODC to replicate and cache the passwords for users and computers before the accounts try to log on in the
branch office.

Not C. You don’t need to add User1 to the Allowed RODC Password Replication Policy group. As a first step
you should run Active Directory Users and Computers as a member of the Domain/Enterprise Admins
group.-
