CompTIA Cloud+ (CV0-003) — Question 154

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 correct answer is D because network issues can often lead to reduced storage throughput, especially in a virtualized environment. The other options, while potentially related to performance, do not directly address the immediate concern of throughput degradation as seen in the performance graphs.
