An architect must improve reliability of a multi-AZ workload that has a single-AZ Amazon RDS instance as a single point of failure. Which is the MINIMUM change?
AIncrease the instance size
BDisable backups
CAdd more EC2 web tier capacity
DEnable Multi-AZ on the RDS instance (synchronous standby in another AZ)
Answer & Solution
Correct answer: D. Enable Multi-AZ on the RDS instance (synchronous standby in another AZ)
Multi-AZ RDS is the SPOF fix (per SAP-C02 §3.4). Sizing/capacity don't address SPOF; disabling backups worsens reliability.
