ISC2 Certified Cloud Security Professional (CCSP) Practice Question
Your company hosts a customer-facing application on a single IaaS cloud region. Management states: service must be recoverable within 1 hour (RTO ≤ 60 minutes) and tolerate up to 10 minutes of data loss (RPO ≤ 10 minutes) if the primary region fails. Ongoing costs must remain as low as possible; manual DNS cut-over is permissible. Which cloud DR pattern best satisfies these constraints?
Backup/restore strategy using periodic snapshots copied to inexpensive object storage in another region, restored when needed
Active/active multi-region deployment with traffic load-balanced globally across two fully provisioned regions
Warm-standby deployment with a fully functional but downsized copy of the entire stack running in another region at all times
Pilot-light deployment with continuously replicated data and minimal standby resources in a secondary region, activated by manual DNS failover
A pilot-light strategy keeps a minimal version of the environment-typically the database replicated in near-real time and essential services-running in a secondary region. Continuous or frequent replication allows data loss to be limited to a few minutes, meeting the 10-minute RPO. Because only critical components are powered on, ongoing costs stay relatively low compared with maintaining fully provisioned resources. When a disaster is declared, additional application servers are rapidly deployed and DNS is updated, enabling recovery within about an hour and satisfying the 60-minute RTO.
A simple backup/restore approach usually misses the RPO and often the RTO because restoring large databases and provisioning infrastructure can take many hours. Warm-standby maintains a scaled-down but fully functional stack; it meets the objectives but incurs higher steady-state cost than pilot-light. Active/active multi-region meets or exceeds the objectives but is the most expensive option and unnecessary given the cost constraint.
