Forest is the largest container of objects and that contains Tree, Domain, and OU. In a hierarchical structure, you can provide multiple rights and permission to any object.
Multi-Master Authentications and Multimaster Replication
Active Directory or Active Directory Domain Services provide Multi-master authentications- means you can access your server or resources from multipoint of Administrations.
Multimaster Replication means you can access and modify your AD DS from multiple points of Administrations. If you have changed or updated on your first server it will be automatically replicated on another server in the network.
Multi-Master Authentications and Multimaster Replication are too useful for any user because a single node of failure users can log in and access his computer or resources without failure.
A single Point of access to Network Resources
Active Directory provides a single point of access to network resources you do not need to find out like where is DNS Server, DHCP Server, DNS Server. You just log in on the AD DS server and get information about all the servers and resources.
