The correct answer is B: Create an Amazon RDS for MySQL Multi-AZ DB instance. Use a MySQL native backup that is. Migrating the database to Amazon RDS for MySQL with Multi-AZ provides automated, synchronous replication to a standby instance in another Availability Zone, along with automatic failover. This minimizes both data loss (low RPO) and downtime (low RTO) without requiring you to mana
Question
A company has a web application with a database tier that consists of an Amazon EC2 instance that runs MySQL. A solutions architect needs to minimize potential data loss and the time that is required to recover in the event of a database failure.

- CCreate an Amazon RDS for MySQL Single-AZ DB instance with a read replica. Use a MySQL
- DUse Amazon Data Lifecycle Manager to take a snapshot of the Amazon Elastic Block Store
Explanation
Migrating the database to Amazon RDS for MySQL with Multi-AZ provides automated, synchronous replication to a standby instance in another Availability Zone, along with automatic failover.

This is more operationally efficient and resilient than managing EC2 + EBS snapshots or a single-AZ RDS instance with manual
