Which actions can a database specialist perform to resolve this issue?
(Choose two.)
Restart the application tool used to run queries.
Change to a database instance class with higher throughput.
Convert from Single-AZ to Multi-AZ.
Increase the I/O parameter in Amazon RDS Enhanced Monitoring.
Convert from General Purpose to Provisioned IOPS (PIOPS).
Explanations:
Restarting the application tool may not resolve the I/O capacity issue, as the problem lies with the database’s I/O performance, not the application tool.
Upgrading to a larger instance class with higher throughput can provide more CPU and memory resources, which can help improve the I/O performance.
Converting to Multi-AZ improves availability and fault tolerance, but does not directly address the I/O capacity issue.
Increasing the I/O parameter in Amazon RDS Enhanced Monitoring does not directly resolve the I/O capacity issue; Enhanced Monitoring is for observing metrics, not for altering performance.
Converting to Provisioned IOPS (PIOPS) provides dedicated I/O capacity, which can significantly improve I/O performance by reducing latency and increasing throughput.
In my opinion, the answer is:
Change to a database instance class with higher throughput.
Based on what I know, the answer is:
Change to a database instance class with higher throughput.
