Nutanix Exam NCP-MCI-6.10 Topic 4 Question 3 Discussion

When diagnosing CPU performance issues, CPU Ready Time and CPU Usage are the key indicators of whether more vCPUs are needed.

Option A (VM CPU Ready Time) is correct:

High CPU Ready Time means the VM is waiting for CPU resources, indicating CPU contention.

Option B (VM CPU Usage) is correct:

If CPU usage is consistently high, adding more vCPUs may improve performance.

Option C (Host CPU Usage) is incorrect:

Host-wide CPU usage does not indicate whether a specific VM needs more vCPUs.

Option D (Host Memory Swap Out Rate) is incorrect:

Memory swapping affects RAM performance, not CPU allocation.
