Active Directory site and Service The Active Directory Sites and Services snap-in is a GUI tool that allows IT network administrators to configure Active Directory as a distributed network service
Active Directory Replication Active Directory replication is the method of transferring and updating Active Directory objects from one DC to another DC.

Active Directory Replication
Active Directory Intra Site Replication In an intrasite environment, directory replication is automatic. Intrasite Replication The bridgehead server is a domain controller that you designate to send and receive replicated data at each site. The bridgehead server from the originating site collects all of the replication changes and then sends them to the receiving site's bridgehead server, which replicates the changes to all domain controllers in the site.
Active Directory Inter Site Replication Intersite If active directory infrastructure contains more than one site, a change happens in one site need to replicate over to other sites . This is called as inter-site replication and its topology is different from the intra-site replication.
Understanding Domain and Trust An Active Directory trust (AD trust) is a method of connecting two distinct Active Directory domains (or forests) to allow users in one domain to authenticate against resources in the other. Transitive Trusts Explicit Trusts Shortcut trust
Transitive Trust Two-way transitive trusts are automatically established upon the creation of a subdomain or with the addition of a domain tree into an AD DS forest
Expicit Trust explicitly transitive (between two forest) created trust between two forest root domains. Forest trust are manually created, one-way transitive or two-way transitive trust that allows you to provide access to the resource between multiple forest.
S hortcut Trust Shortcut trusts simply allow authentication verifications to be processed faster, as opposed to having to move up and down a domain tree.
Replication Interval active directory R The default replication interval is 180 minutes, or 3 hours. The minimum interval is 15 minutes. Consider the following criteria to determine how often replication occurs within the schedule window: A small interval decreases latency but increases the amount of wide area network (WAN) traffic
