   A company runs a mission-critical application in the us-east-1 Region. The application must be recoverable within 15 minutes (RTO) and with a maximum of 1 minute of data loss (RPO) in the event of a regional failure. The company has a high budget and prioritizes minimal downtime. Which disaster recovery strategy best meets these requirements?

   • AActive/active: run the application in both us-east-1 and us-west-2 with traffic split between them and synchronous data replication.
   • BPilot light: replicate data to us-west-2 and keep only the database running.
   • CBackup and restore: take snapshots every hour and copy them to us-west-2.
   • DWarm standby: run a scaled-down version of the application in us-west-2 with asynchronous replication.
