   A company runs a critical application that must be able to recover to a consistent state from a specific point in time after a logical corruption event, such as an accidental deletion or a bad software update. The recovery point objective (RPO) is 15 minutes, and the recovery time objective (RTO) is 2 hours. Which storage-based fault tolerance technique should the administrator implement?

   • AStorage snapshots taken every 15 minutes
   • BRAID 10 mirroring
   • CAsynchronous replication with a 1-hour lag
   • DSynchronous replication to a remote site
