Your company has two main offices located in two countries and multiple branch offices in each
country. The wide area network (WAN) link between the offices has restricted and limited
connectivity. The network consists of two Active Directory forests. The functional level of the forests
is Windows 2000 Server. Each forest includes a root domain and four child domains. All resources for
each forest are located only in a single country. You plan to deploy Active Directory Domain Services
(AD DS). The AD DS deployment must support the following requirements:
Replication traffic between the main offices must be minimized.
Users in all offices must be able to access resources in all other offices.
The solution must use the minimum amount of domains.
Which migration strategy should you recommend?
A.
Restructure to a two-domain, two-forest Active Directory structure.
B.
Restructure to a single-domain, single-forest Active Directory structure.
C.
Restructure to a multi-domain, single-forest Active Directory structure.
D.
Upgrade all existing domains and maintain the existing Active Directory structure.
Explanation:
To deploy Active Directory Domain Services (AD DS) and to make sure that the replication traffic
between both the main offices are minimized and the users in all offices are able to access resources
in all other offices, you need to modify the structure to deploy a two-domain, two-forest Active
Directory structure. Usually a single forest is sufficient in many situations. However you need more
than one forest if the network is distributed among many autonomous divisions as in this scenario,
where two main offices are located in two different countries. Therefore you need two-forest Active
Directory structure. You need to deploy two domain structures because you need to minimize the
replication traffic between both the main offices. Replication traffic can be avoided by creating a
separate domain for both the head office locations and not replicating that domain to the branch
offices. In a forest containing a single domain, every object in the forest is replicated to every
domain controller in the forest. This might lead to objects being replicated to places where they arerarely used, which is an inefficient use of bandwidth. For example, a user that always logs on at main
office location does not need their user account replicated to a branch office location.
