A cloud administrator notices that the performance of a database-heavy application has degraded significantly. They suspect an I/O bottleneck on the storage device assigned to the application. What is the BEST way to confirm if the storage device is the cause of the performance degradation?
Check the CPU utilization of the servers hosting the database to rule out CPU performance issues.
Monitor the Input/Output Operations Per Second (IOPS) and throughput on the storage device during peak operation times.
Ensure the storage device has the latest firmware updates installed.
Review Virtual LAN (VLAN) configurations to ensure there is no network segmentation impacting storage access.
