StructureSitesLogical representations of physical structureLocations where all computers are well-connectedWell-connected means that all computers in a single site are connected by high-speed, reliable, and cost-effective links (such as a LAN)Sites and site links have three main purposesControlling replicationProviding local logonsControlling certain directory-enabled applications

StructureControlling replicationTypes of replicationIntrasiteOccurs spontaneously based on database changes Allows for fast database convergence, but can be chaotic and bandwidth-intensiveIntersiteOccurs between designated bridgehead servers according to a schedule and interval Always compressedPath can be influenced by modifying the costs associated with site

between sites with a monitoring application to determine periods of peak activity and amount of available bandwidth during periodIf link(s) have a low amount of available bandwidth during peak periods, configure a schedule for the site link that excludes peak periodsDesigning a Site Structure (4)(Skill 2)10.10 © 2004 Pearson Education, Inc.Exam 70-297 Designing a Microsoft® Windows® Server
