Which solution will meet these requirements?
Eliminate the Multi-AZ deployment. Run the DB instance in only one Availability Zone
Recreate the DB instance. Use the default storage type. Reload the data from an automatic snapshot
Switch the storage to Provisioned IOPS SSD on the DB instance that is running
Recreate the DB instance. Use Provisioned IOPS SSD storage. Reload the data from an automatic snapshot
Explanations:
Eliminating the Multi-AZ deployment reduces availability and fault tolerance, which doesn’t address the issue of high latency in database writes.
Using the default storage type (General Purpose SSD) does not provide the required performance boost, and recreating the DB instance is unnecessary.
Switching to Provisioned IOPS SSD storage increases I/O performance, which is needed for high OLTP workloads and reduces database write latency.
Recreating the DB instance and switching to Provisioned IOPS SSD storage is unnecessary if the current instance can be modified directly without recreating it.
