Table 3-1 shows that some of the naming contexts in the XYZ Corporation are held on several servers in order to provide faster access and to reduce the connection costs by keeping information local.
One server holds the master copy, the others are replicas.
Table 3-2 shows the replication strategy for each naming context in the XYZ Corporation directory service.
