A private cloud administrator needs to configure replication on the storage level for a required RPO of 15 minutes and RTO of one hour. Which of the following replication types would be the BEST to…

Cold storage is designed for archival and infrequent access, not for achieving a low RPO of 15 minutes or an RTO of one hour, as recovery from cold storage is typically much slower.

Regional replication refers to replicating data within a specific geographic region, which describes the scope of replication, not a replication type that defines the specific RPO/RTO characteristics directly.

Asynchronous replication copies data to a secondary location after the primary writes are acknowledged locally, introducing a slight delay but allowing for geographic distance and lower bandwidth requirements. This delay results in a small potential data loss window (the RPO), which can typically be configured to be within 15 minutes, while still providing data for a recovery within an RTO of one hour.

Multiregional replication refers to replicating data across multiple geographic regions, which, similar to regional replication, describes the scope of replication rather than a replication type that directly addresses the RPO/RTO timing characteristics.
