CompTIA Cloud+ (CV1-003) — Question 6

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?

Answer options

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

Correct answer: D

Explanation

The next step should be to verify the network because issues with network performance can lead to reduced storage throughput, especially in an IaaS environment relying on NFS. The other options, such as application performance, SAN issues, and VM GPU settings, are less likely to be the direct cause of the observed decrease in storage performance since CPU, memory, and latency metrics are stable.
