Nutanix Certified Master – Multicloud Infrastructure (NCM-MCI) — Question 46

An administrator receives reports that VDI desktop performance in an 8-node Nutanix VDI environment is poor. Opening applications takes between 1 and 2 minutes. When investigating the issue, the following conditions are found:
✑ Cluster memory utilization: 80%
✑ Cluster SSD utilization: 70%
✑ Average VM CPU Wait Time: 11%
✑ CVM CPU utilization: 75%
Which action should be taken to improve VDI performance?

Answer options

• A. Increase the amount of SSD storage in the cluster.
• B. Add memory to the nodes in the cluster.
• C. Add CPU resources to the cluster.
• D. Increase the number of vCPU cores allocated to the CVM.

Correct answer: C

Explanation

The correct answer is C because increasing CPU resources can help reduce the average VM CPU Wait Time of 11%, which indicates that VMs are waiting for CPU resources to become available. The other options do not address the immediate bottleneck related to CPU resources, as memory and SSD utilization are not critically high.
