Actual exam question from CompTIA's CV0-003

Question #: 294
Topic #: 1

An OS administrator is reporting slow storage throughput on a few VMs in a private IaaS cloud. Performance graphs on the host show no increase in CPU or memory. However, performance graphs on the storage show a decrease of throughput in both IOPS and MBps but not much increase in latency. There is no increase in workload, and latency is stable on the NFS storage arrays that are used by those VMs. Which of the following should be verified NEXT?

A. Application
B. SAN
C. VM GPU settings
D. Network

Selected Answer: D

Given that CPU and memory usage on the host are not showing abnormalities, and latency on the storage arrays is stable, the next thing to investigate in this scenario should be the **network**. When storage throughput decreases while latency remains stable, it's often an indication that there might be a network-related issue causing the slowdown. Check the network connections and settings, including any potential bottlenecks or misconfigurations in the network infrastructure between the VMs and the storage. So, the correct answer is: **D. Network**

Could be SAN ?

I initially thought SAN too because of the decrease in IOPs, but it's probably the SAN decreasing IOPs in accordance with the lack of throughput.
