- 正解だと思う選択肢: B
In HA configuration standby instance can't be in another region
👍 5chelbsik2022/12/26 B. A is not HA. B would be HA. C doesn’t make sense and neither does D. Cloud SQL is a regional service which means the failover replica is in the same region as the primary - hopefully in a different zone. Read replicas can be in different regions, but they’re read replicas not failover replicas.
