2V0-622 Question #172: Real Exam Question with Answer & Explanation
The correct answer is D: Increase the CPU limit assigned to SlowVM.. The esxtop output shows the VM is being throttled by a CPU limit, so removing or raising that limit is the correct fix.
Question
Refer to the Exhibit. Examine the esxtop command output shown in the Exhibit. Which option would improve application performance for the SlowVM virtual machine?
Exhibit
Options
- AIncrease the number of vCPUs provided to SlowVM.
- BDecrease the number of vCPUs provided to SlowVM.
- CMove SlowVM to another ESXi host with more physical CPU resources available.
- DIncrease the CPU limit assigned to SlowVM.
Explanation
The esxtop output shows the VM is being throttled by a CPU limit, so removing or raising that limit is the correct fix.
Common mistakes.
- A. Adding more vCPUs does not resolve throttling caused by a CPU limit; the scheduler will continue to cap the VM at the same MHz ceiling regardless of vCPU count.
- B. Decreasing the vCPU count reduces the VM's scheduling parallelism and does not address the root cause of a configured resource limit.
- C. Migrating to another host does not help because the CPU limit is a VM-level configuration that travels with the VM and will continue to throttle it on any host.
