A company's cloud application experienced a complete regional failure. Post-incident analysis reveals that all data was stored in a single region with no replication. Backups exist but are also in the same region. The recovery took 6 hours. Which operations design changes would best address both the RTO and data loss risk for future incidents?

Question

Accepted Answer

A. Implement cross-region data replication for active data and store backups in a separate region; deploy the application in an active-active or active-passive multi-region configuration to reduce failover time. Cross-region replication minimizes data loss by maintaining a synchronized copy in another region, addressing RPO. Multi-region active-active or active-passive deployment enables rapid failover, addressing RTO. The CompTIA Cloud+ V4 Operations domain covers backup and recovery including cross-region strategies for business continuity.
