Answers to Review Questions
1. A, D. The switch to the Windows 2000 native domain functional level is a one-time, one-way
switch and is irreversible. Once you have switched to the Windows 2000 native domain
functional level, you will no longer be able to have Windows NT 4.0 domain controllers
within the organization.
2. D. Windows Server 2003 (along with Windows 2000 Server) and Active Directory sup-
port two-way transitive trusts between domains. When a child domain is created, a trust
relationship is automatically configured between that child domain and the parent domain.
This trust is two-way, meaning that resource access requests can flow from either domain
to the other.
3. C. The domain controller on which the change is made will wait 15 seconds (to account
for any additional changes) and then will begin replicating its changes to the other domain
controllers within that site. After replication has occurred with the first replication partner
of the domain controller, it will wait 3 seconds and then commence replication with its next
replication partner, and so forth, until the original domain controller has replicated with all
replication partners within that site.
4. C. A domain tree is a hierarchical arrangement of one or more Windows Active Directory
domains that share a common namespace. Domain Name Service (DNS) domain names
represent the tree structure. The first domain in a tree is called the root domain.
5. B. To create a Windows Server 2008 domain controller, you first install the Active
Directory Domain Services role on it and then run DCPromo. During this process, you
have the option of creating a new domain or joining an existing domain. If you create a new
domain, you also have the option of creating or joining an existing domain tree or forest.
6. A. An organizational unit is a container in which you can place objects such as user accounts,
groups, computers, printers, applications, file shares, and other organizational units. An orga-
nizational unit cannot contain objects from other domains and is the smallest unit to which
you can assign or delegate administrative authority. Organizational units are provided strictly
for administrative purposes and convenience.
7. B. DNS is the primary provider of name resolution for Windows Server 2003–based net-
works. In fact, the Windows Server 2003 domain structure is based on DNS structure, and
Active Directory requires that DNS be used.
8. C. All messages in Exchange Server 2007 are routed to their destination mailbox by the
Hub Transport server, even if the message is sent between recipients on the same Exchange
Mailbox server.
9. B. Any changes that need to be made to the schema of the forest must be made on the
schema master. Exchange Server 2007 requires schema modifications and thus will fail to
install if the schema master cannot be contacted.
10. B. The Hub Transport server, which is responsible for message routing in Exchange Server
2007, computes the lowest-cost route to the site containing the destination Mailbox server
based on the site link costs configured on Active Directory site links between the sites.
