Exam Highlights

Before taking the exam, review the key points and terms that are presented in this chapter. Return to the lessons for additional practice.

Key Points

• You must have an ADC installed in each domain that contains Exchange Server 5.5 servers.

• Exchange 2000 Server ADCs must be upgraded to the Exchange Server 2003 version prior to installing Exchange Server 2003.

• The Site Replication Service can run only in a mixed-mode Exchange organization.

• If the ADC is installed on a domain controller, you must change the LDAP port used by connection agreements.

Key Terms

connection agreement A connection agreement defines what and how data will be replicated between the Exchange Server 5.5 directory and Active Directory. A connection agreement is part of an ADC, and an ADC can contain multiple connection agreements.

LDAP port The Lightweight Directory Access Protocol (LDAP) is an industry standard protocol for accessing information in directories. Active Directory uses LDAP extensively, and if you install an ADC on an Active Directory domain controller, you must change the default LDAP port in your connection agreements.

replication Replication is the process of synchronizing data between two or more directories or databases. Replication enables Active Directory and the standalone Exchange Server 5.5 directory to synchronize so that changes made in one directory are automatically reflected in the other.
