Q44 Single choice

A company has an application that uses a MySQL database that runs on an Amazon EC2 instance. The instance currently runs in a single Availability Zone. The company requires a fault-tolerant database solution that provides a recovery time objective (RTO) and a recovery point objective (RPO) of 2 minutes or less.

Which solution will meet these requirements?

A
Migrate the MySQL database to Amazon RDS. Create a read replica in a second Availability Zone. Create a script that detects availability interruptions and promotes the read replica when needed.
B
Migrate the MySQL database to Amazon RDS for MySQL. Configure the new RDS for MySQL database to use a Multi-AZ deployment.
C
Create a second MySQL database in a second Availability Zone. Use native MySQL commands to sync the two databases every 2 minutes. Create a script that detects availability interruptions and promotes the second MySQL database when needed.
D
Create a copy of the EC2 instance that runs the MySQL database. Deploy the copy in a second Availability Zone. Create a Network Load Balancer. Add both instances as targets.
