An architect must remediate a SPOF in a single-AZ RDS DB serving a multi-AZ web tier. Which DOP-C02 §3.1 change is the canonical fix?
ADisable backups
BIncrease the instance size only
CAdd more web tier capacity
DEnable Multi-AZ on the RDS instance (synchronous standby in a second AZ + automatic failover)
Answer & Solution
Correct answer: D. Enable Multi-AZ on the RDS instance (synchronous standby in a second AZ + automatic failover)
Multi-AZ RDS removes the SPOF (per DOP-C02 §3.1). Sizing/capacity don't address SPOF; disabling backups worsens reliability.
