The correct answer is A. Add more Provisioned IOPS SSD (io1) EBS volumes. Use OS commands to create a Logical. The maximum provisioned IOPS for io1 is 64000 and hence you can achieve higher aggregate performance by adding more io1 volumes.
Question
A company recently performed a lift and shift migration of its on-premises Oracle database workload to run on an Amazon EC2 memory optimized Linux instance. The EC2 Linux instance uses a 1 TB Provisioned IOPS SSD (io1) EBS volume with 64,000 IOPS. The database storage performance after the migration is slower than the performance of the on-premises database. Which solution will improve storage performance?
Options
- AAdd more Provisioned IOPS SSD (io1) EBS volumes. Use OS commands to create a Logical
- BIncrease the Provisioned IOPS SSD (io1) EBS volume to more than 64,000 IOPS.
- CIncrease the size of the Provisioned IOPS SSD (io1) EBS volume to 2 TB.
- DChange the EC2 Linux instance to a storage optimized instance type. Do not change the

Explanation
The maximum provisioned IOPS for io1 is 64000 and hence you can achieve higher aggregate performance by adding more io1 volumes.
