What action should be taken to improve the performance of VDI desktops in a Nutanix environment with high utilization rates?

To improve the performance of Virtual Desktop Infrastructure (VDI) desktops in a Nutanix environment experiencing high utilization rates, adding CPU resources to the cluster is an effective approach. High utilization often indicates that the current CPU resources may be insufficient to handle the demands of VDI workloads. By increasing the number of CPU cores or the overall CPU capacity in the cluster, you can enhance the processing power available for these workloads, which leads to better responsiveness and reduced latency for users.

Enhancing CPU resources directly addresses bottlenecks that can occur at the processing level, allowing for more simultaneous operations, faster execution of tasks, and improved overall system performance under load. This is particularly crucial for VDI environments, where user experience is heavily reliant on the performance of virtual desktops.

The other options, while they may also contribute to overall system performance, do not specifically target the key bottleneck that high CPU utilization indicates. For instance, increasing SSD storage can help with data retrieval speeds but may not resolve CPU contention issues. Similarly, adding memory can support applications that require more RAM but may not alleviate CPU-related slowdowns. Lastly, increasing vCPU cores allocated to the Controller Virtual Machine (CVM) can be beneficial, but focusing on the cluster's overall CPU resources is
