An AWS workload in a VPC is running a legacy database on an Amazon EC2 instance. Data is stored on a 200GB Amazon EBS (gp2) volume. At peak load times, logs show excessive wait time.What solution should be implemented to improve database performance using persistent storage?

• Migrate the data on the Amazon EBS volume to an SSD-backed volume.

• Change the EC2 instance type to one with EC2 instance store volumes.

• Migrate the data on the EBS volume to provisioned IOPS SSD (io1).

• Change the EC2 instance type to one with burstable performance.
