2V0-622 Question #171: Real Exam Question with Answer & Explanation
The correct answer is B: Decrease the number of vCPUs assigned to SlowVM.. When an SMP VM exhibits high Co-Stop due to over-assigned vCPUs on a contended host, reducing vCPU count, offloading competing VMs, or migrating to a less loaded host are the correct remediation actions.
Question
Refer to the Exhibit. An administrator is troubleshooting a CPU performance related problem for the SlowVM virtual machine. Which three actions should the administrator take to improve CPU performance for SlowVM? (Choose three.)
Exhibit
Options
- AIncrease the number of vCPUs assigned to SlowVM.
- BDecrease the number of vCPUs assigned to SlowVM.
- CPower off other VMs running on the same ESXi host.
- DIncrease the CPU limit for SlowVM.
- EMove SlowVM to another ESXi host with more physical CPU resources available.
Explanation
When an SMP VM exhibits high Co-Stop due to over-assigned vCPUs on a contended host, reducing vCPU count, offloading competing VMs, or migrating to a less loaded host are the correct remediation actions.
Common mistakes.
- A. Increasing the number of vCPUs on an already contended host worsens Co-Stop values because it becomes even harder for the scheduler to find enough free physical cores to simultaneously schedule all vCPUs.
- D. Increasing the CPU limit would only help if the VM were being throttled by an existing limit; the exhibit indicates the issue is scheduling contention, not a configured resource cap.
