Step-by-Step Explanation:
Understand the Problem:
The application on a general-purpose EC2 instance experiences performance issues during I/O intensive tasks.
High VolumeQueueLength indicates a bottleneck in I/O operations.
Analyze the Requirements:
Improve disk I/O performance to handle intensive read/write operations.
Evaluate the Options:
Option A: Modify the instance type to be storage optimized.
This could help but may not be necessary if increasing IOPS on the EBS volume resolves the issue.
Option B: Deselect Auto-Enable Volume I/O.
This option is not relevant to addressing high VolumeQueueLength.
Option C: Modify the volume properties to increase the IOPS.
Increasing IOPS directly addresses the I/O performance bottleneck.
Option D: Enable enhanced networking.
Enhanced networking improves network performance but not disk I/O performance.
Select the Best Solution:
Option C: Increasing the IOPS of the EBS volume directly addresses the high VolumeQueueLength and improves I/O performance.

Optimizing EBS Performance
Modifying the volume properties to increase the IOPS ensures that the application can handle intensive read/write operations more effectively.
