Your network contains a multi-site Active Directory Domain Services (AD DS) forest. Each Active Directory site is connected by using manually configured site links and automatically generated connections.

To minimize the latency for changes to Active Directory in a multi-site environment, you need to ensure that replication of directory data is efficient and timely across all sites. There are several ways to achieve this, but the most effective ones are:
A. Modify the site link costs: Site link costs determine the order in which replication occurs between sites. By default, all site links are created with a cost of 100, which means that they are all considered equally important. However, you can modify the cost of each site link to prioritize replication traffic between specific sites. For example, if you have two sites that are far apart and have a slow WAN link between them, you can increase the cost of the site link between them to ensure that replication traffic uses a faster route. Conversely, if you have two sites that are close together and have a fast LAN link between them, you can decrease the cost of the site link between them to prioritize replication traffic over other site links.
B. Create a site link bridge: A site link bridge is a logical connection between site links that allows replication traffic to flow between them without having to traverse another site link. Site link bridges are useful when you have a complex topology with multiple site links and you want to optimize replication traffic between specific sites. For example, if you have two hub sites that are connected to multiple spoke sites, you can create a site link bridge between the two hub sites to ensure that replication traffic between them is efficient and timely.
C. Modify the options attribute: The options attribute of a site link determines how replication traffic is handled between sites. By default, all site links are created with a set of default options that are appropriate for most environments. However, you can modify the options attribute to optimize replication traffic for specific scenarios. For example, you can enable the "Use Notify" option to ensure that changes to directory data are replicated immediately instead of waiting for the next replication cycle.
D. Modify the replication schedule: The replication schedule determines when replication occurs between sites. By default, replication occurs every 180 minutes (3 hours) between sites. However, you can modify the replication schedule to ensure that replication occurs more frequently or less frequently, depending on your needs. For example, you can increase the replication frequency during peak business hours to ensure that changes to directory data are replicated in a timely manner.
Overall, the best approach to minimize latency for changes to Active Directory is to use a combination of these techniques, depending on your specific environment and requirements.
