Question #: 38
Topic #: 1

An administrator is trying to diagnose a performance issue and is reviewing the following output:

System Properties:

CPU: 4 vCPU -

Memory: 40GB -

Disk maximum IOPS: 690 -
Disk maximum throughput: 44Mbps | 44000Kbps
Based on the above output, which of the following BEST describes the root cause?

A. The system has reached its maximum IOPS, causing the system to be slow.
B. The system has reached its maximum permitted throughput, therefore iowait is increasing.
C. The system is mostly idle, therefore the iowait is high.
D. The system has a partitioned disk, which causes the IOPS to be doubled.

the TPS of sdb and sdb1 add up to 690, which is the disk's maximum IOPS. Therefore, the answer is A. Answer B says "permitted" - that's not a technical limitation, that's configuration.

you cant see IOPS using this command, so those are irrelavent. high iowait means that the system is stuck or that a it's not able to provide enough resources
