ISC2 Certified Cloud Security Professional (CCSP) Practice Question
A retail organization hosts its mission-critical order-processing database in a public cloud. A recent business impact analysis states that, if the primary region is lost, no more than 15 minutes of data may be lost (RPO) and service must resume within 60 minutes (RTO). At present the database runs in a single region and relies on once-per-day snapshots. Which change to the architecture most effectively satisfies the stated BIA requirements?
Copy the daily snapshot to on-premises storage and perform a full restore in the event of a disaster.
Increase snapshot frequency to every two hours and store the snapshots in long-term cold storage.
Convert the deployment to a multi-zone cluster within the same region and enable automated daily backups.
Enable continuous asynchronous replication to a secondary region and maintain a warm standby database instance that can be promoted during failover.
Continuous asynchronous replication to a secondary region keeps the replica nearly current, so at failover no more than a few minutes of data are lost, comfortably meeting the 15-minute RPO. Because a warm standby instance is already running, only promotion and redirection of traffic are required, allowing service restoration well inside the 60-minute RTO. Increasing snapshot frequency still involves a time-consuming full restore, which normally exceeds a one-hour RTO. Multi-zone clustering in the same region improves availability but does not protect against a regional outage, leaving RPO and RTO unmet. Copying daily snapshots off-site provides geographic diversity but both the backup interval and full restore process violate the 15-minute RPO and likely the 60-minute RTO.
