An architect needs to design HA across two GCP regions for a critical workload. Which approach best maps to the Well-Architected reliability pillar?
AManual disaster-recovery scripts run by oncall every quarter
BDisabling backups to save cost
CMulti-region deployment with failover and replicated data (active-passive or active-active)
DSingle-zone deployment in one region
Answer & Solution
Correct answer: C. Multi-region deployment with failover and replicated data (active-passive or active-active)
Multi-region HA with replication + failover is GCP's canonical HA design. Single-zone has no zone-failure protection; manual DR is brittle; disabling backups violates the reliability pillar.
