Selected Answer: B
Aurora replicates data to the secondary AWS Regions using dedicated infrastructure, with latency typically under a second. The secondary clusters allow you to make an Aurora global database available in a new primary AWS Region more quickly (lower RTO) and with less data loss (lower RPO) than traditional replication solutions. https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-global-database.html
