1 00:00:06,430 --> 00:00:14,380 When you deploy Active Directory Domain Services it's important to provide an efficient sign in infrastructure 2 00:00:14,740 --> 00:00:18,080 and a highly available directory service. 3 00:00:18,230 --> 00:00:26,530 Implementing multiple domain controllers throughout the infrastructure helps you achieve both of these 4 00:00:26,530 --> 00:00:27,460 goals. 5 00:00:27,460 --> 00:00:35,620 However you must ensure that Active Directory replicates its information between each domain controller 6 00:00:35,620 --> 00:00:36,860 and the forest. 7 00:00:36,940 --> 00:00:44,410 In this course you'll learn how Ada ESA replicates information between domain controllers within a single 8 00:00:44,410 --> 00:00:48,230 site and throughout multiple sites. 9 00:00:48,250 --> 00:00:56,770 You also will learn how to create multiple sites and how to monitor replication to help optimize aided 10 00:00:56,770 --> 00:01:00,700 s replication and authentication traffic. 11 00:01:00,700 --> 00:01:08,520 After completing this course you'll be able to describe how aided s replication works configure Ada 12 00:01:08,520 --> 00:01:16,870 decides to help optimize authentication and replication traffic and you'll be able to configure and 13 00:01:16,900 --> 00:01:20,080 monitor aided the replication. 14 00:01:20,110 --> 00:01:20,950 Let's start.
