You learned about the various types of replication — snapshot, transactional, and merge — and the different topologies that can be used with replication. You learned how to monitor replication using the Replication Monitor, the Performance Monitor, and the relevant performance counters, and about some of the replication DMVs and system stored procedures.
Along with log shipping, database mirroring, and clustering, SQL Server 2008 provides many features to satisfy customers needs for load balancing, high availability, disaster recovery, and scaling.
