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, indicatingCPU contention.
Option B (VM CPU Usage) is correct:
If CPU usage isconsistently high, adding more vCPUsmay 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 swappingaffects RAM performance, not CPU allocation.
