Splunk Enterprise Certified Architect Practice Test

What is one characteristic of migrating from a single-site to a multisite index replication?

1. A master node is needed at each site.

2. Multisite policies only apply to new data.

3. Single-site buckets receive multisite policies instantly.

4. Multisite total values must not exceed single-site factors.

The correct answer is: Multisite policies only apply to new data.

Migrating from a single-site to a multisite index replication involves several important characteristics, one of which is that multisite policies only apply to new data. This means that the configurations and replication strategies designed for multisite deployments are enforced on data that comes in after the migration has been completed. Any existing data prior to the implementation of multisite configurations remains unchanged; it is not retroactively subjected to the new policies. This is significant because it allows for a seamless transition without disrupting the existing data integrity while providing an opportunity to apply new replication strategies for future incoming data. The implementation of multisite architectures focuses on enhancing data resilience and availability for data that is ingested after the changeover, thus optimizing the infrastructure's performance and reliability moving forward. The other characteristics that suggested options pertain to operational specifics of multisite environments, such as the need for a master node in each site and the behaviors of data buckets during the migration, but they do not capture the key aspect of how multisite replication policies are applied primarily to new data.
