VCP-VVF Troubleshoot And Optimize Practice Question
An administrator is troubleshooting a virtual machine that is experiencing slow performance. The administrator opens vSphere Client performance charts and notices that the guest OS CPU usage is low, but the host CPU ready time for the VM is extremely high. What does this indicate?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The host physical CPUs are overcommitted, causing the hypervisor to delay scheduling the virtual machine's vCPUs.
High CPU ready time with low guest OS CPU usage means the VM wants to run and is ready, but the ESXi scheduler is making it wait because the physical host CPUs are heavily overcommitted or constrained.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The host physical CPUs are overcommitted, causing the hypervisor to delay scheduling the virtual machine's vCPUs.
Why this is correct
High ready time is a direct sign of CPU contention and overcommitment on the ESXi host.
- ✗
The datastore backing the VM is experiencing high I/O latency.
Why it's wrong here
Storage latency affects storage metrics (DAVG), not CPU ready time.
- ✗
The virtual machine has been configured with too many vCPUs relative to workload demand.
Why it's wrong here
While oversized vCPUs can contribute to co-stop or ready time, high ready time primarily reflects host CPU contention and scheduling constraints.
- ✗
The guest operating system's internal firewall is blocking CPU execution threads.
Why it's wrong here
Firewalls filter network packets, not CPU execution threads.
