   A company runs a critical application that must have an RPO of 5 minutes and an RTO of 1 hour. The application data is stored in a cloud database. The current backup strategy uses nightly full backups and hourly transaction log backups. The company is considering switching to continuous database replication to a standby instance. Which statement correctly evaluates the trade-off?

   • AContinuous replication is always cheaper than nightly backups because it uses less storage
   • BContinuous replication reduces RPO to near zero but may increase cost and complexity; the RTO depends on the failover mechanism and whether the standby is pre-warmed
   • CContinuous replication eliminates the need for backups, so RTO becomes zero
   • DHourly transaction log backups already meet the 5-minute RPO, so replication is unnecessary

   A company runs a critical application in a single cloud region. The business has an RTO of 30 minutes and an RPO of 15 minutes. The application is stateful and cannot run in active-active mode. Which disaster recovery strategy best meets these requirements?

   • APilot light: keep a minimal standby environment in a secondary region, replicate data continuously, and scale up on failover
   • BMulti-site active-active: run the application in both regions simultaneously
   • CBackup and restore: take hourly backups and restore to a new environment in the secondary region
   • DWarm standby: maintain a partially running environment in a secondary region with continuous data replication and automated failover
