ISC2 Certified Cloud Security Professional (CCSP) Practice Question

A SaaS provider runs its customer-facing ERP application on virtual machines spread across a single public cloud region. A recent business impact analysis set a recovery time objective (RTO) of 4 hours and a recovery point objective (RPO) of 15 minutes. Budget constraints rule out fully active-active operation, but management wants a solution consistent with ITIL service continuity management guidance. Which resiliency design best meets these requirements while keeping costs moderate?

  • Deploy a warm standby environment in a second region with asynchronous database replication every five minutes, scaling up resources only during a failover.

  • Maintain a pilot-light instance in another availability zone, replicating data once per day and automating infrastructure build on demand.

  • Implement an active-active multi-region deployment with synchronous data replication and global load balancing across sites.

  • Rely on a cold standby site that is provisioned from weekly full backups stored in object storage.
